Q:Can not use it two brick

Acidic silica brick refractory material, has good ability in acid slag erosion

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:High temperature refractory material?

Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, the refractory material used for special occasions.Now the definition of refractory materials, has not only depends on whether the refractoriness at 1580 DEG. Refers to the current refractories used in metallurgy, petrochemical, cement, ceramics and other production equipment with inorganic non-metallic materials.

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

That is because the brick load softening point the maximum temperature is 1450 degrees.

Q:The specific content is what gb/t2608-2012 brick

The provisions of the brick classification, technical requirements, test methods,

Q:Brick

Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.

Q:Such purpose and scope please give me detailed points thank you because I am learning stage

Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature. The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass. Tridymite and cristobalite and quartz remaining at low temperature due to phase change, volume changes greatly, so the brick thermal stability at low temperature is very poor. In use, under 800 degrees Celsius, slowly heating and cooling, so as not to produce cracks. The use of temperature in blast furnace so should not be below 800 DEG on. The properties and process of silica crystal with SiO2 transformation is closely related, therefore, the proportion of it is one of the important quality indexes of silica brick. General requirements below 2.38, high quality silica brick should be less than 2.35. The true density is small, reflecting a large number of scale quartz and square quartz in the brick, the residual quartz is small, so the residual line expansion is small, and the strength is decreased in useThe raw materials for the manufacture of silica brick. The higher the SiO2 content of silica raw material, the higher the refractoriness. The most harmful impurities are Al2O3, K2O, Na2O and so on. They seriously reduce the refractoriness of refractory products. Brick with SiO2 content of not less than 96% of silica as raw materials, adding mineralizer (e.g. millscale, lime) and binder (such as molasses, sulfite pulp waste liquid), after mixing, molding, drying, sintering and other processes in the system.

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:Which material is good for furnace refractory?

Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.

Q:Why in the production of the brick to detect the volume density

Density is the property of material, different density of materials, density of the same kind of material is not up to standard, affecting performance.
