1 Transport of refractory materials and refractory products 1.1 All refractory materials and refractory products used in furnace construction must have a factory qualification certificate that meets t

Firebrick stacking skills: 1. According to different parts of the furnace fire bricks are stacked; 2. According to the composition of firebrick, firebrick specification and size, respectively stacked;

The following common problems should be avoided when laying refractory bricks: (1) Dislocation: that is, uneven between layers and layers, blocks and blocks; (2) Tilt: that is, uneven in the horizonta

According to Al? O? -SiO? Binary phase diagram of the system, mullite composition in Al? O? 79%, SiO%21% or so is more appropriate, but considering the presence of a certain amount of impurities in th

The synthesis method of mullite can be divided into sintering method and electric melting method. Sintering method can be divided into dry method and wet method according to the way of raw material pr

The production of mullite materials can generally be made of kaolinite, sillimanite group minerals, aluminum hydroxide or aluminum oxide and silicon dioxide directly synthesized. Clay materials react

Is mullite produced in 3Al? O? ·2SiO? The crystalline phase is the main component of refractory raw material. Mullite is divided into natural mullite and synthetic mullite. Natural mullite is r

There are many types of abrasives, corundum abrasives are often used, corundum is divided into several kinds, today we will understand it together. When it comes to abrades, we will think of white cor

The purpose of smelting brown corundum is to better generate corundum, so that it can achieve better heat and wear resistance characteristics. As an important industrial raw material, brown corundum h

Brown corundum is bauxite, coke (anthracite) as the main raw materials, in the arc furnace by high temperature smelting, with it made of abrasive tools, suitable for grinding high tensile metal, such

Brown corundum is a new polishing material commonly used in our industrial production, but many friends do not know where brown corundum can also be used? Brown corundum is the use of bauxite, carbon
