Q:How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?

Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks

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:What are the main constituents of refractory bricks?

Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:

Q:The formula in the refractory brick, and firing curve, who knows?

By silica powder, 81-85%, perlite 15-19%, plus the total weight of the main raw materials of the following accessories

Q:Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450

Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.

Q:Why is the three oxidation of two silicon is very harmful impurities in silica brick

Heating calcination is the best way to extend this sort of impurity removal. Remove impurities

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

Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use, but the anti alkali erosion ability, thermal shock stability is the worst, a scrap. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.

Q:The difference between clay refractory bricks and refractory brick in the application.

Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use,

Q:Which material is good for furnace refractory?

Kiln types of refractories is very extensive, selection of refractory materials according to the type of furnace furnace temperature and use of selected refractory material, refractory material is divided into custom products of refractory bricks and unshaped refractory castable series products. According to chemistry, it is divided into acidic, neutral and alkaline materials.
