Les réfractaires sont une classe de matières premières industrielles utilisées à haute température, corrosion chimique et autres environnements de travail difficiles, widely used in steel, Métaux non-ferreux, verre, ciment, céramique, pétrochimique, machinerie, chaudières, industrie légère, pouvoir électrique, military and other fields of the national economy, is to ensure the production of the above industry operation and technological development of essential basic materials, in the development of high temperature industrial production plays an important role The important role of replaceable. Although in different fields and specific applications, the type and performance of refractories are very different, different kinds of refractories have their own unique properties, but in general, refractories need to have some of the following important properties: high temperature stability: refractories need to maintain structural stability at high temperature for a long time, do not produce brittle rupture and oxidation corrosion; Chemical erosion resistance, refractories need to have the ability to resist the erosion and corrosion of various chemical substances to ensure long-term use in special media, excellent mechanical strength: refractories need to have high strength and toughness, can withstand the impact of mechanical shock and thermal demand and other factors; Good heat resistance, refractories need to have a certain thermal shock safety factor, to avoid thermal shock damage due to sharp temperature changes; Good thermal conductivity and heat insulation: refractories need to be able to properly conduct heat or isolate heat sources, so as to maintain the temperature stability of the surrounding environment of the equipment; Good cohesiveness and workability: refractories need to have good plasticity and cohesiveness, which is easy to manufacture and process into various shapes, sizes and structures.

As important non-metallic mineral resources, refractory vanadium, brown corundum and white corundum play an important role in industrial production. They are widely used in metallurgy, matériaux de construction, industrie chimique, machinery manufacturing and other fields. Cependant, in its processing and application process, some impurities will be doped, which will affect the quality and service life of the material.

As a kind of high temperature material, fire-resistant mature vanadium soil has excellent high temperature resistance and is often used in iron and steel industry. In its production and use, it is necessary to remove some impurities. Par exemple, the physical properties and high temperature oxidation resistance of the material that the metal elements such as iron, Qin, and bear in refractory cooked keshi will shadow. En outre, mineral impurities such as quartz and calcite will also affect the fire resistance and thermal conductivity of the material, seriously affecting the service life of the material.

Brown King is a kind of high hardness, high density exciting grinding material, often used in materials, abrasives and other fields, but it will be affected by some impurities in the morning. Par exemple, the dyes in Kangwang mainly include Ca, Mg, Co and other elements, and these elements will affect the physical and mechanical properties and electrical conductivity of the material. En outre, impurities in brown corundum include quartz, dolomite and calcite. These minerals will affect the wear resistance, toughness and strength of brown corundum, reducing the quality of the material.

Baigang Wang is also an important non-metallic mineral resources, often in abrasives, céramique, chemicals and other fields. But in the process of its production and application, it will also be affected by similar dyes. Par exemple, the main chemicals in Baigang Wang are aluminum, calcium, magnésium, sodium and other elements, and doping these elements will affect the physical and mechanical properties and electrical conductivity of the material. En outre, impurities such as quartz kimono clay will also affect the color and transparency of the white Kong king, shadow its application in the field of sea and optics. En résumé, it is very important to eliminate the dye in important materials such as refractory mature woven soil, brown Gang Wang and white Gang Wang. Only by reducing the existence of impurities as much as possible, can the quality and service life of materials be guaranteed, and the technical level and industrial competitiveness of related fields be further improved.
