Product Description

Topchase Tundish Refractory brick

Tundish Refractory brick feature:

It is refractory seating block as base brick for ziconia insert nozzle IN Tundish.

With high erosion resistance

Work together with zirconia nozzle can keep long time no change on shape

No crack etc good feature,can custom make as per client 's drawing,better meet client requirement.

Tundish Refractory block brick were used for tundish,used together with zirconia nozzle,for

continuous casting of blooms, billets ,rectangular billet and slab casting.

Q: The introduction of silica brick: The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass

Q: Physical solid waste disposal: Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.

Q: The introduction of silica brick: Brick refers to the content of more than 93% products SiO2. Brick with SiO2 content of not less than 96% of silica as raw materials, adding mineralizer and binder, through mixing, molding, drying, sintering and other processes in the system. The higher the content of SiO2 in silica raw material, the higher the refractoriness of the product. According to the use of brick varieties, divided into: coke oven silica brick, brick for hot blast stove, electric stove with brick, brick for glass furnaces. According to the transformation is divided into: standard bricks, tiles, bricks and general special brick etc..

Q: Semisilica brick, clay brick, high alumina brick and what is the difference?: This is a kind of refractory material is divided into three types: semisilica brick (A12O315 ~ 30%), clay brick (A12O330 ~ 48%), high aluminum brick (A12O3>48%).

Q: The United States of our brick anti-dumping duties?: . According to the relevant legal procedures, the United States International Trade Commission will make a final ruling on the anti dumping industrial injury before January 6, 2014, if an affirmative determination, the U.S. Department of Commerce will be involved in product release tax anti-dumping order.

Q: Why is the three oxidation of two silicon is very harmful impurities in silica brick: Can generate the material needs is the best way to see the impurity problem!! the first consideration is whether can get the material impurities with what method choice after the time! Miscellaneous reactions cannot have new impurity formation! Selected cannot and need material reaction reagent!

Q: The chemical composition of silica brick and its physicochemical index?: Brick refers to the refractory products in more than 93% of the content of SiO2

Q: What is the silica refractory products?: High silicon content in high temperature expansion sintering temperature between 1390-1410 in furnace arch

Q: High temperature refractory material?: Special materials often use AZS brick (i.e. corundum brick), corundum brick, magnesia chrome bricks, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Insulation refractories are often used diatomite products, asbestos products, insulation board. Unshaped refractories are often used refractory castable, refractory clay, refractory ramming material, refractory plastic and fettling material, fire resistance, gunning, refractory cast material, fireproof coating, lightweight refractory castable, gun mud.

Q: Such purpose and scope please give me detailed points thank you: Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
