Development and Prospect of Refractories

refractory material is a refractory degree of not less than 1580 degrees, a better thermal shock and chemical erosion, low thermal conductivity and low expansion coefficient of inorganic non-metallic materials. Its widely used in iron and steel, glass, cement and other industries. Refractories have their own characteristics have been proven advantages, but its shortcomings and deficiencies are also different. The development of refractories on the whole in the new products, new processes, such as the direction of development trends.

Refractory material firebrick refractory is mainly made of raw materials such as bauxite, dolomite, silica, magnesite, steel fiber and so on. The development of refractories in the national industrial production applications have a pivotal position.
Refractory materials basic refractories according to the product shape and compact degree, a casting method, melt blowing method, sintering method. Sintering method is part of the raw material pre-firing clinker, cracking and screening, and then a certain percentage of mixing with the raw materials, through molding, drying and firing. The purpose of raw materials is to burn the moisture, organic debris and gas burned. Reduce the sintering products shrink to ensure the accuracy of finished size. In order to homogenize the ingredients and particles of the various raw materials and clinker, kneading is carried out while the binder is added to enhance the bonding strength.

Casting method is to mix raw materials through the process of mixing and fine grinding, in high temperature baking, direct casting, cooling crystallization, annealing into products.

The melt blow method is a method in which the ingredients are melted and then sprayed with high pressure air or superheated steam to disperse them into steel fibers or hollow spheres.
