Q:The United States of our brick anti-dumping duties?

At present of our brick anti-dumping rate is 73.10%

Q:The chemical composition of silica brick and its physicochemical index?

The physicochemical index of silica brick:Turn left to |

Q:Can not use it two brick

The softening temperature is up to 1640~1670 DEG C, and the volume is stable at high temperature for a long time.

Q:Because of the recent relates to this industry, by way of learning to name for all raw materials, I hope knowledgeable friends exhibitions, thank you.

The main raw material is the main body of refractory. Auxiliary raw materials can be divided into binders and additives. The role of bonding agent is to make the refractory body in the production and use process has enough strength. There are commonly used lignin, phenolic resin, asphalt, cement, water glass, phosphoric acid and phosphate, sulfate, some main raw material itself has the effect of binder, such as clay; additive is to improve the production of refractory materials and construction technology, or strengthen the refractory material of some properties, such as stabilizer, water reducing agent, inhibitor, plasticizer, foaming agent, dispersing agent, bulking agent, antioxidant.

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 difference between clay refractory bricks and refractory brick in the application.

The ability of alkali resistance is poor, the thermal shock stability is the worst, and it is scrapped at one time. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.

Q:What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you

Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.

Q:Such purpose and scope please give me detailed points thank you

Mainly used for coke oven carbonization chamber and the combustion chamber wall, open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace, refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.

Q:Physical solid waste disposal

The production of silicon material is added to the cause of waste brick:Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products during firing

Q:The brick is mainly used in the place?

Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
