Customer in Mexico ordered 45 tons refractory fire bricks and 36 rolls ceramic fiber blankets
In Jan. 45 tons refractory fire bricks and 36 rolls ceramic fiber blankets are packed for delivering to customer in Mexico. High quality and nice price refractory fire bricks and insulation thermal materials in Topower Refractory.
The following we will talk out the performance and molding method of glass kiln with clay bricks.
Fireclay refractory bricks are refractory products produced by refractory clay as raw materials. It is widely used in industry. Fireclay bricks are divided into ordinary clay bricks, multi -familiar clay bricks, all -rayed clay refractory fire bricks and high silicon clay bricks.
Clay refractory fire bricks are acidic refractory materials, and their acidity gradually weakens as the content of AL2O3 in the brick. Its thermal guidance rate is the lowest of all refractory materials. Although its fire resistance is as high as 1700 ° C, the softening temperature of the lotus is only about 1300 ° C. This is the biggest disadvantage of clay bricks. Therefore, it cannot be loaded or compressed during high temperature use. When it is eroded by a large amount of R2O, its softening temperature will be further dropped to about 1050 ° C, so it can only be used at the lower part of the lower part of the pool wall or the bottom of the pool bottom. The thermal expansion rate of clay bricks is the smallest of common refractory materials. At the same time, due to the small crystals of clay refractory fire bricks and small pores, it is evenly distributed, which makes the stress easier to get buffer, so it is strongly resistant to heat resistance. The lower temperature of the lower part of the heat storage room, the grid brick, the flue and the daily glass pond furnace, the refractory material accessories near the supply machine, such as the punch, the bowl of the bowl, and other places where the heat -resistant impact is required, it can fully play a role.
There are many ways to make clay refractory fire bricks, which can be formed, tinked, squeezed, mud pouring molding, and high pressure molding of mud. Different molding methods, the nature of the product is very different. Even if the types of chemical ingredients and raw materials are exactly the same, the nature of the bricks will be different due to the different molding methods. Different forming methods are adopted according to different use sites. The heat storage room grid bricks, small brick size, the best product for molding with high pressure pressure machines; for large -scale pond wall bricks, material groove bricks, etc. The best mud casting method of vacuum exhaust. It is better to form with pounding.
