The details of Furnace Bottom Tapping Hole Fillers

Introduction:

EAF tapping hole filler also called Furnace bottom tapping hole filler which is used in steel tapping hole of EAF bottom. To meet the increased requirements for large size EAF, Changxing refractory developed this ideal tapping hole filler to replace the traditional type. Our EAF tapping hole filler is well known for its excellent corrosion and scouring resistance of iron steel, long operating life and easy execution and mending. Further, these can be provided in different specifications as required by the clients. The automatic opening rate of Changxing Refractory’s EAF tapping hole filler can reach 98%.

EAF tapping hole filler can be packed into different package based on the different tonnage of EAF, which is convenient for using and without environmental pollution. Compared with similar imported products, our EAF tapping hole filler can greatly reduce the cost of steel melting.

Advantages:

Long operating life

Easy execution and mending
Excellent corrosion and scouring resistance of iron steel
Specific Application: EAF tapping hole filler is used as tap hole filler in EAF bottom. The automatic casting rate can reach 98%.?

The details of Mullite Insulating Firebrick

Introduction:

There are many kinds of light Mullite Insulating Firebrick, we call the one with mullite as principal crystalline phase Mullite Insulating Firebrick. In the mineral composition, besides mullite, the ones with low Al2O3 content also contain a small quantity of glass phase and cristobalite, the ones with high Al2O3 content is with a small quantity of corundum.

Light Weight Mullite Insulating Firebrick can be widely used as lining or insulation layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry.

Advantages:

Mullite Insulating Firebrickhas excellent thermal shock resistance, strong resistance to the corrosive gas and slag.

Refractory Products containing a large number of closed pores, and a lightweight high temperature, good insulation properties, refiring small contraction, excellent thermal shock resistance, strong resistance to the corrosive gas and slag. Products can greatly improve the thermal efficiency of the kiln to shorten the production cycle, reduce the kiln body weight to achieve energy saving.

Application:

Light mullite insulating brick can be directly used in the lining of high temperature kilns and furnaces. Mullite Insulating Firebrick has already been widely used in shuttle kiln, roller hearth furnace, glass furnace, etc.

Changxing refractory provides refractory products, calcium silicate products, castable & mortar, china refractory brick, ceramic fiber felt, ladle & tundish nozzle, ceramic fiber with high quality for you. Such as high alumina refractory bricks, magnesia carbon brick, clay refractory bricks and other refractory?products.

The supplier of high power graphite electrodes

We are instrumental in manufacturing for our clients a commendable array of Graphite Electrodes that are demanded for their ease of use, long time service and options for wide ranging usages. Offered range also incorporates Ultra high power graphite electrodes, HP graphite electrode and Regular Power Graphite Electrodes. These offered Electrodes are prepared by using LWG Furnaces, advanced machinery and latest techniques. Backed by its excellent attributes, this offered range is extensively applauded by our patrons. Addition to this, we ensure customized product for the gratification of esteemed clients.
SDGEs are usually manufactured from petroleum coke, regardless of the grade. Some SDGEs are manufactured with high-grade coke, others with a lower grade coke. In fact, some SDGEs are a blend of several different grades. LDGEs on the other hand, are more commonly manufactured with premium, 100% high grade needle coke.
There are different grades specified within both electrode types, such as:
HP – HP graphite electrode
HD – High Density
UHP – Ultra High Power
SHP – Super High Power

There are also other grades including regular power (RP), normal power (NP), and medium power or (MP). However, these grades are less commonly used. Do you need HP graphite electrode? We offer best HP Graphite Electrode with lowest price. HP GraphiteElectrode - Graphite Electrodes Manufacturers - Changxing Refractory. Welcome to view our web to know more details.

Design and Application of Tapping Sleeve Brick

The tapping sleeve brick is the channel for the molten steel from converter to the ladle. It directly contacts with the molten steel and its life directly affects the steel making rhythm of the converter. From the structure, tapping sleeve bricks are divided into monolithic sleeve brick and split sleeve brick. The monolithic sleeve brick is generally used isostatic compression molding, split sleeve brick is used machine pressure molding.

Whether it is monolithic or split type, the inner holes is a circular structure of the through-hole. The hole size according to tapping time, and the wall thickness is generally 50-100mm. The hole shape is divided into straight and trumpet-shaped. Experiments show that the trumpet-shaped hole and the circular inlet shape, the tapping speed is faster, which means that the interference between the molten steel and the tap hole is weakened and the water flow is relatively stable, shortens the tapping time. There have many kinds of refractory products in our factory.

Changxing refractory provides refractory products, calcium silicate products, castable & mortar, china refractory brick, ceramic fiber felt, ladle & tundish nozzle, ceramic fiber with high quality for you.

Ladle Submerged Entry Nozzle

Submerged entry nozzle was development in 1960s. At first time, it was produced from quartz. With the development of continuous casting, it can not meet the requirement of high level continuous casting and special steel casting.

With the improvement of the level of casting, especially special steel casting, quartz submerged entry nozzle can not meet requirement of casting life and steel quality. Therefore, aluminum carbon and aluminum carbon-zirconium carbon combined submerged entry nozzles came out. Compared to quartz submerged entry nozzle, this nozzle is of much longer service life. In order to adapt to low carbon steel casting, the inner layer of the ladle nozzle uses special refractory materials like aluminum magnesium, ceramics, etc. For casting aluminum killed steel, nozzle would easy to get block out of caking. Against this condition, both blowing argon in the way of ventilation and using non-carbon-containing and calcium zirconate material have achieved a good result. To solve some emergency working conditions, non-baking submerged entry nozzle was developed. By the methods of designing the trapezoidal submerged nozzle, and mounting impeller in the nozzles, we can make slag floating, in which way blocking can be well prevented.

Changxing refractory provides refractory products, calcium silicate products, castable & mortar, china refractory brick, ceramic fiber felt, ladle & tundish nozzle, ceramic fiber with high quality for you. Such as high alumina refractory bricks, magnesia carbon brick, clay refractory bricks and other refractory products.
