Photos for Workshop
- 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: 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: What is acid refractory?
- Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.
- Q: Glass kiln brick for physical and chemical indicators?
- Glass kiln with high quality silica brick with silicon oxide content, low melt index, mainly used for glass kiln crown, parapet, wall hanging, small furnace arch superstructure and regenerator.
- Q: How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
- Mainly from the impurities to determine how much, generally less impurity single color brick.
- Q: How to improve the thermal conductivity of the coke silicabrick rate?
- The content of SiO2 is 98.23% crystalline silica as raw material, with sulfite pulp liquid as binder, millscale and lime as mineralizer, by Jin Hongshi (TiO2) as additive, can improve the rate of thermal conductivity of silica brick for coke oven. When the rutile content is 1.5%, the coefficient of thermal conductivity of silica brick for coke oven is 2.66W/ (m.k).
- Q: What are the main constituents of refractory bricks?
- Clay brick and clay brick are mainly composed of mullite (25% ~ 50%), glass phase (25% ~ 60%) and square quartz and quartz (up to 30%). Usually with hard clay as raw material, pre calcined mature material, and then with soft clay, semi dry or plastic molding, the temperature at 1300~1400 C fired clay brick products. Can also be added a small amount of water, glass, cement and other binders to make non burning products and amorphous materials. It is a refractory brick commonly used in blast furnaces, hot blast furnaces, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory bricks.
- Q: Brick
- 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.
- Q: Why in the production of the brick to detect the volume density
- Fast density test, please consult an instrument.
- Q: Physical solid waste disposal
- 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 when firing, reduce cracks, improve the rate of finished products.
