High Alumina Brick Manufacturing Process

Views: 43     Author: Site Editor     Publish Time: 2023-02-09      Origin: Site

The manufacturing process of high alumina bricks is similar to that of clay bricks.But the difference is that the proportion of clinker used in high alumina bricks is relatively high,up to 90~95%.Before the clinker is crushed and fired at a high temperature of up to 1500~1600 degrees,all the iron slag is selected and screened out.RS Group Manufacturer, as a supplier of high alumina refractories in China,proved that in order to improve the quality of high alumina brick products,it is necessary to store high alumina clinker in strict grades, then finely grind the bauxite clinker, and stick the clay together.

High Alumina Brick Raw Materials High Alumina Bricks-

According to different resource conditions and product requirements,RS high alumina brick manufacturers generally use the following raw materials to produce high-quality high alumina bricks:

  • High alumina bauxite, containing the gibbsite minerals bauxite and bauxite.

  • Sillimanite minerals including andalusite,kyanite and sillimanite.

  • Synthetic materials such as synthetic mullite,industrial alumina and fused corundum.China is a land with high-quality and abundant high-aluminum raw material resources.As a leading manufacturer of high-alumina refractory materials in China,RS company has the best raw material resource advantages.

Fire brick

Refractory bricks,refractory bricks or refractories are blocks of ceramic material used to line furnaces,kilns,fireboxes and fireplaces. Refractory bricks are primarily built to withstand high temperatures,but also typically have a lower thermal conductivity for energy efficiency.Typically dense refractory bricks are used in applications with extreme mechanical,chemical or thermal stress,such as the interior of wood-fired kilns or furnaces,where they are subject to abrasion of wood,melting of ash or slag, and high temperatures.In other,less harsh situations,such as in electric or gas kilns,perforated bricks (commonly called "kiln bricks") are a better choice.They are weaker,but lighter,easier to shape and better insulators than dense bricks.Under no circumstances should the refractory bricks spall and their strength should remain good during rapid temperature changes.

High temperature applications

Silica refractory bricks lining steelmaking furnaces are used at temperatures as high as 3,000 °F (1,649 °C),which melts many other types of ceramics and in fact partially liquefies the silica refractory bricks.High-temperature reusable surface insulation (HRSI),a material with the same composition,is used in space shuttle insulation tiles.Basic refractory bricks are used in non-ferrous metallurgical processes because the slag used in these processes readily dissolves "acid" silica bricks.The most commonly used basic refractory bricks for smelting non-ferrous metal concentrates are "chrome magnesia" or "magnesia chrome bricks" (depending on the relative proportions of magnesite and chromite used in their manufacture).
