Vervaardiging van gesmolten magnesiumoxide

Fused magnesia has the characteristics of high purity, large crystal grains, dense structure, sterke slakweerstand, en goede thermische schokstabiliteit. It is an excellent high-temperature electrical insulation material and is also used for making high-grade magnesia bricks, magnesia koolstofstenen, and unshaped An important raw material for refractory materials. Fused magnesite is widely used in metallurgy, chemische industrie, national defense, scientific research, ruimtevaart, household appliance components, enz.

The specific production process of fused magnesite

In specific industrial production, the raw materials of fused magnesia of different specifications are also different. Ordinary fused magnesia usually uses magnesite directly as raw material, while large crystalline fused magnesia uses light-burnt magnesium as raw material. The equipment adopts Submerged arc furnaces mostly using three regenerated or non-regenerated graphite. The specific process is: feeding → ignition and lifting of electrode → gradual feeding → smelting (magnesite is sintered and melted by the heat generated by high current) → natural cooling → crushing, classification, and sorting → warehousing.

Advantages of fused magnesia

It has a complete structure, dense structure, high melting point (up to 2800°C), stable chemical properties, hoge druksterkte, strong insulation properties, erosiebestendigheid, en corrosiebestendigheid. It is an important raw material for metallurgy, bouwmaterialen, light industry, furnace lining, and bulk materials. It is also an indispensable and important refractory material in steel, cement, glas, smelten van non-ferrometalen, en andere industrieën.

Main applications of fused magnesite

In the metallurgical refractory industry, it is used to produce auxiliary refractory materials such as high-purity fused magnesia, gunning materials, and ramming materials, as well as special refractory bricks such as flowing steel bricks, magnesiumoxide bakstenen, En magnesiumoxide chroomstenen. It can also be used in vacuum and non-vacuum induction It is used as refractory lining on furnaces and electric arc furnaces. It is an ideal raw material for making magnesium oxide crucibles, furnace bladders, and various high-temperature casings.
