Some refractory parts are small and may possess a complex and delicate geometry; others are massive and may weigh several tons in the form of precast or fusion cast blocks.
What Are Refractories Made Of?
Refractories are produced from natural and synthetic materials, usually nonmetallic, or combinations of compounds and minerals such as alumina, fireclays, bauxite, chromite, dolomite, magnesite, silicon carbide, zirconia, and others.
What Are Refractories Used For?
In general, refractories are used to build structures subjected to high temperatures, ranging from the simple to sophisticated, e.g. fireplace brick linings to reentry heat shields for the space shuttle. In industry, they are used to line boilers and furnaces of all types--reactors, ladles, stills, kilns--and so forth.
Depending upon the application, refractories must resist chemical attack, withstand molten metal and slag erosion, thermal shock, physical impact, catalytic heat and similar adverse conditions. Since the various ingredients of refractories impart a variety of performance characteristics and properties, many refractories have been developed for specific purposes. It is a tribute to the refractory engineers, scientists and technicians, and plant personnel that more than 5000 brand name products are listed in the latest Product Directory of the Refractories Industry in the United States.

why not know what are refractories made of now ?

The volume of refractories consumed is projected to rise in the USA, Western Europe, and Japan following an extended period of decline, as economic conditions strengthen in these areas and output of ferrous metals and other refractories-using products rebounds. Output gains in these areas are more likely to result in higher refractories demand because the manufacturing techniques used are already so efficient that it will be much difficult to reduce refractories consumption on a per unit output basis than in less developed countries.
Due to their greater use of more costly, high-quality products, the US, Western Europe, and Japan will account for a larger share of the world refractories market in dollar terms in 2020 than they will in tonnage?ChangXing Refractory is a Chinese leading refractory and oil fracturing proppant manufacturer & supplier with a wide range industries in high temperature field .

While this definition correctly identifies the fundamental characteristics of refractories--their ability to provide containment of substances at high temperature--refractories comprise a broad class of materials having the above characteristics to varying degrees, for varying periods of time, and under varying conditions of use. There are a wide variety of refractory compositions fabricated in a vast variety of shapes and forms which have been adapted to a broad range of applications.
The common denominator is that when used they will be subjected to temperatures above 1000°F (538°C) when in service. Refractory products fall into two categories: brick or fired shapes, and specialties or monolithic refractories. Refractory linings are made from these brick and shapes, or from specialties such as plastics, castables, gunning mixes or ramming mixes, or from a combination of both.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.

The differences between water and waterless tapping clay

Generally speaking, there are two big classifications of tapping clay, which are water and water-less tapping clay.Chinafirebrick provides refractory products, calcium silicate products, castable & mortar, fire brick, ladle & tundish nozzle, ceramic fiber with high quality for you.

The main content of water tapping clay is fire clay, refractory material, pitch and water, which is mainly applied for less than 200m3 blast furnace.

Water less tapping clay is mainly made from coke powder, refractory clay powder, pitch,high alumina bauxite, silicon carbide and so on. This kind of tapping clay is applied for more than 200m3 blast furnace.

Compared with water tapping clay, water less tapping clay has better performance. As water tapping clay with less active principle, when using the tapping clay need to add middle temperature agglutinant, which made tapping clay easy to melt. Thus the erosion resistance performance become poor, which may lead to molten steel spatter.

While water less tapping clay can reduce 25min working temperature at least when working, and also make sure stable tapping iron.

Except water and water less tapping clay, there are also resin bonded tapping clay in our factory, which is the best one for blast furnace.

If you need tapping clay, please tell us the size of your blast furnace, and we can provide you the exactly recommendation.You can enjoy best service onChinafirebrick.com.

Effect of slide gate and refractory nozzle on molten steel leakage

Ladle nozzle and slide gate are key items in a steel casting system, which must with high quality or it will be very dangerous for workers.

Following are some items that may lead to molten steel leakage

1. Nozzle well block
Nozzle well block?usually with lower high temperature strength, when changing upper nozzle with pneumatic pick, it is easy to be damaged. Molten steel will flow into gaps and lead to molten steel leakage.

2.Upper nozzle usually with poor thermal stability. When changing ladle, and temperature difference will hurt upper nozzle and result in explosion.

3.Slide gate will bear eroding from molten steel when working. After long time working, and there will be indentation on the slide gate, which will result in gap between two slide gate, and molten steel will let out between two gates.

4.Lower nozzle is easy to explosion. When casting steel, there will be flaw on lower nozzle due to heat stress. The flaw will be very dangerous when casting.

So it is very important to choose high quality nozzle and slide gate. There are different brands nozzle and slide gate in our factory, such as C40, B60 and so on, which can meet all your casting requirements.
