Special high alumina bricks and ordinary high alumina bricks are different in performance, index and usage. The main reason is the difference in internal quality. Special grade bricks are made of special grade bauxite raw materials. The content of the special grade ra··· ...

Due to the process and equipment requirements of industrial kilns in metallurgy, building materials, glass, electric power, chemical industries and other industries, refractory materials must be built as linings. The performance of refractory materials directly affect··· ...

1 Preparation of mud for high alumina bricksFirst, prepare the clay mud. The clay mud is prepared in a mud mixer, the density of the mud is 1.50~1.65g/cm3, and the temperature is 50~70℃.The mud is prepared in a wet mill. The preparation procedure is as follows: accor··· ...

Highalumina bricks are aluminum silicate refractory products containing more than 48% aluminum oxide (A203). If the content of A203 is higher than 90%, it is called corundum brick, because the standards of different countries are not completely consistent due to diffe··· ...

High alumina brick is one of the commonly used refractory bricks. It belongs to the silicon-aluminum refractory material and the neutral refractory brick. It is commonly used in various large and medium-sized thermal kiln equipment or smelting kilns, according to GB/T··· ...

Thermal shock resistance refers to the ability of refractory materials to resist damage caused by rapid changes in temperature. It has been called thermal shock stability, thermal shock resistance, temperature sudden change resistance, and rapid cold and heat resistan··· ...

The process of removing moisture from solid materials is called drying. The drying process of refractory materials is roughly divided into: drying of raw materials and drying of semi-finished products after molding. If the water content of soft clay exceeds 12%, it wi··· ...

The production of high alumina bricks usually uses soft clay or semi-soft clay as a binder. The role of clay in the compounding is to improve the molding properties of the mud and to make the molded and dried body have a certain strength. However, during the firing pr··· ...

Finding and choosing a castable refractory concrete appropriate for use in heater construction can be difficult. Requirements are: high density, large aggregate and high tolerance to thermal shock. The castable used here is Mount Savages Heatcrete 24 ESC (24 f. extra ··· ...

What is the difference between iron ditch material and iron ditch castable? Before understanding the difference between iron ditch material and iron ditch castable, we need to know what iron ditch material and iron ditch castable are in order to better distinguish bet··· ...
