Product Picture
Produce Processing
- Q: Physical solid waste disposal
- Reduce crack production and improve yield. The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem
- Q: The hot blast stove when the temperature did not rise against the brick interface decreased
- Insulation of hot blast stove, key insulation silica brick hot stove, hot blast stove is shutdown or need repairing in blast furnace.
- Q: Why will expand when heated brick
- In the process of SiO2 drying, the four crystalline transformation points of 117, 163, 180~270 and 573 DEG C are found, among which the volume expansion caused by the 180~270 is the largest.
- 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: 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: 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: What role does silica play in refractories?
- Low fractory refers to the alumina content between 10%~30%, SiO2 content is less than 85%, semisilica brick SiO2 = 65%,The SiO2 content of not less than 93%, refractory material to natural quartz rock as the main raw materials are called silica, silica brick, silica brick, quartz glass and special products. China's literature generally put this type of product is called "siliceous refractory products", which is the most important brick.
- 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: 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: 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.
