4.Put one layer of high alumina blowing felt on the ladle wall.
5.The gap distance between ladle wall working layer and high alumina blowing felt would be permanant layer thickness (normally would be 70-110mm). After installing working layer of 3-5 layers (about 300-500mm high), inject running castable into the gap between ladle wall working layer and high alumina blowing felt. Then use trowel to make the castable hard. Repeat the above procedure until LF construction finished.
6.On basis of optimized sintering method, sinter the ladle for 24 hours. After sintering, the ladle can be used.

Install the LF in above method, it has advantages as following.

1.Permanant layer and working layer are installed at same time, in which way they can be combined closely. During sintering period, deformation of permanant layer can be sperated. In this way, gap would not appear, and improve safe of the LF.
2.Permanant layer running castable is of high strength, it would not be easy to be damaged when unpacked and translated.?
3.No need mold, in which way can avoid damage the ladle brick by vibrating.
4.No need to sinter the permanant layer seperately. The LF would be sintered for 24 hours in optimized method. During actual working, it would not cause problem of gas in melton steel rising up.

Come to know the application of fire bricks on chinafirebrick

Would you like to know more fire brick for sale?There have many kinds of refractory products in our factory .The storage and installation parameters associated with monolithic refractories vary across specific manufacturers and products but, generally speaking the materials and water used to mix the material should be between 60 degrees and 80 degrees Fahrenheit at the time of installation and during the period of time within which the “initial set” takes place.
When long-term climate controlled storage of materials is not possible, the following tips may prove to be valuable:
Consider temporary heated storage such as a shipping container, tent, or trailer.
Consider encapsulating and heating the work area. In addition to ensuring that the materials are installed at the proper temperature, encapsulating the work area also contributes to the comfort of the employees performing the work and prevents dust from traveling to unintended areas.
Relocate items not used during a maintenance outage to accommodate material storage.
Coordinate “just in time” delivery of materials from a climate controlled environment to minimize the period of time the materials are exposed to cold temperatures.
Use totes, barrels, tanks, etc. in conjunction with heating devices in order to ensure water is the proper temperature prior to mixing. Be careful when heating water. If the water is too warm, it can cause the material set-time to decrease which also has the potential to adversely impact material properties and performance.When you need any china fire brick , Please tell us the product material, style, size and quantity ordered and other specific requirements, so our customer service staff to give an accurate quote.

would u like to know more information about Refractory Dry-Out？

Changxing Refractory is a Chinese leading refractory and oil fracturing proppant manufacturer & supplier with a wide range industries in high temperature field . From a refractory bricks manufacturing factory, Changxing has become a professional manufacturer with various refractory materials and oil fracturing proppant both in domestic and international market during 30+ years, whose customers covers North America, Middle East, Asia, Africa, etc.
For many refractory installations, the dry-out portion of the project can be the most frustrating. It looks like the work is completed, the vessel looks brand new, and there are always intense pressures to “fire it up” and get production ramped back up after a costly outage. At Schad, we are often asked by customers, “Do we really need to do this?” or “Isn’t there something that we can do to speed this up?” In some cases, alternative materials may be an option, and may provide value if they can eliminate or expedite this step of the project, however, once the materials have been placed the answer is almost certainly a resounding, “No!”
Although it may be tempting to speed things up or by-pass the dry-out step altogether, it is critical to understand that aggression with regard to a dry-out schedule in the short-term can have highly costly long-term ramifications. Wherever possible it is advisable to be conservative. Getting a refractory lining too hot too fast can cause excessive cracking, spalling, or may even cause significant portions of a new installation to blow up. It may also negatively impact the properties achieved by the new materials decreasing their useful lifespan.
There have many kinds of fire bricks in our factory.what's more ,There also have many kinds of refractory products in chinafirebrick.Always consult the refractory installer and the material manufacturer in order to obtain a dry-out schedule and adhere to it as closes as possible in order to avoid major pitfalls.Changxing has a production line, which is base on oil & gas applied ceramic proppant, and also with 3 factories focusing on all kinds of refractory materials used for iron & steel casting, cement, glass petrochemical and ceramics industries.

Purposes of steelmaking

Steel is made by pig iron produced by blast furnace and DRI sponge iron and scrap as raw material, using different melting methods into steel, which include converter steelmaking method, open hearth furnace, electric arc furnace steelmaking etc. three categories. All the three kinds of steel-making process can meet the general quality requirements of steel users.

In order to meet requirements for higher quality and more varieties of high-grade steel, there has a variety of handling methods for molten steel outside of the furnace (also known as refining), such as blowing argon, vacuum degassing and desulfurization outside of furnace etc. By additional refining processing of molten steel produced from converter, open-hearth furnace and electric arc furnace etc, we can get advanced steel grades.

For some high-quality steel for special purpose and special requirements, if further processing outside of furnace still can not meet requirements, then we will use a special method for steel refining, such as ESR, which is a complicate refining process need secondary refining. After got molten steel from converter, open-hearth furnace or electric arc furnace steel smelting, do casting for forging to make it as electrode, then start secondary refining by heating with remelting slag.There have many kinds of refractory products in our company , such as fire brick, refractory nozzle ,refractory raw materials etc.

1. Reduction in physical properties – Improper water content leads to a reduction in the physical properties associated with a monolithic refractory material. This can decrease the lifespan of the refractories as well as create issues for the end user throughout the time period in which they are in use. In many cases, end users select more costly refractories in order to acquire higher quality materials. The improper addition of water can completely negate this additional spend. In many cases leading to performance, that is inferior to properly mixed lower quality materials.
2. Increased set-up time – Materials in which too much water has been added will not set-up at the rate which they were designed to. In some cases, they may not set-up at all and may remain soft, spongey, or grainy. This may lead to the need to remove and re-cast the materials causing long and expensive delays. Furthermore, the rate at which monolithic refractories cure has an impact on the physical properties achieved. Accelerating and decelerating this reaction can have negative implications.
There are ways to insure that materials are properly mixed. These methods include adequate training of the workforce, proper communication, have the mixing and use instructions available during an installation, have proper measuring devices available, and the use of mixing logs and even third party inspectors.Changxing has a production line, which is base on oil & gas applied ceramic proppant, and also with 3 factories focusing on all kinds of refractory materials used for iron & steel casting, cement,fire bricks glass petrochemical and ceramics industries.

Buy fire brick with high quality in chinafirebrick now

These days, it can be overwhelming and exhausting listening to all of the talk about wearing the proper PPE for the task that is being performed. It can be easy to tune this talk out, but that is a dangerous road to travel.Do you need any refractory products ? Such as fire brick , fire briks and refractory castable.There are many kinds of refractory products and refractory materials in our factory .
There are certain types of PPE that everybody is familiar with and are predominantly available on the work site. These include safety glasses, steel toe boots, and gloves to name a few, but PPE isn’t that simple. When it comes to construction work, and more specifically, refractory installation it is critical to match the PPE being worn to the material being installed as well as the installation method being used.
For starters, all refractory materials are not created equal. Some materials are “phosphate bonded.” These materials can be corrosive in nature and additional precaution should be taken when working with them since they can pose additional risk to the eyes and skin. Especially when using liquid phosphate bonded or “two component” mixes, goggles and corrosive resistant gloves should be considered. Single component products such as phosphate bonded plastics should also be considered to pose an additional risk to individuals installing them.
Aside from material type, installation method should also be considered. Cutting bring or “shooting” refractory materials in lieu of vibration casting can lead to additional risk to the eyes and a face-shield should likely be considered. Furthermore using monolithic materials or “dry-cutting” products can create excessive dust and appropriate respiratory protection should be used.
At times, it seems as though there are as many combinations of materials and installation methods as there are stars in the sky. It is important to understand the specific hazards posed by each material and installation method prior to using the products. When it comes to safety, all products are not created equal. Be sure to refer to product data sheets, SDS information, mixing and using instructions, and lean on industry experts such as manufacturers and qualified contractors in order to prevent injuries.If you need any fire brick or refractory products , welcome to view our website to know more kinds of refractory products.

Kerneos India plans to complete the construction of its US$18.9m, greenfield 30,000t/yr calcium aluminate cement plant in Visakhapatnam within the next two years. The ground-breaking ceremony was held on 20 May 2015. The Vizag plant will be Kerneos' 12th manufacturing plant globally. Three of its plants are located in France, three are in China, one is in the UK and one is in the US.Changxing Refractory is a Chinese leading refractory and oil fracturing proppant manufacturer & supplier with a wide range industries in high temperature field .
Calcium aluminate cement is specialty cement used mostly by manufacturers of refractories. Demand for the specialty cement hinges directly on the growth of the steel industry. Segi P Idicula, managing director of Kerneos (India and Middle East), said that the Vizag plant's capacity would be taken up as the market grows. India currently consumes 50,000t/yr of calcium aluminate cement as refractory binder. Kerneos supplies about 10,000t/yr to Indian refractory makers from its French and Chinese plants.
Idicula said the Indian Government is aiming at a total steel production of 250Mt/yr by 2025. "At this rate, the Indian refractory industry will almost triple in size and there will be a corresponding rise in demand for calcium aluminate binders. We expect the refractory binder market to double from the current 50,000t/yr by 2020," said Idicula.
Currently in India, there are several small-scale merchant producers and several refractory producers manufacturing the binders for captive use. Kerneos, which has 30 customers in India, expects to double its market share in this segment in the next five years. Pierre Baillagou, Kerneos director (Industrial) said that the company plans to sell the entire production from its Vizag unit for the domestic refractory industry.
