How to improve the quality of magnesium products?

An important way to improve the quality of refractory materials is to increase the purity of the product, reduce the amount of low-melting matter, and increase the density and high temperature strength of the product. High-density magnesium refractories and high-purity direct combination of magnesium refractories are important trends in the development of magnesium refractories at home and abroad in recent years.
 

High-purity raw materials, high-pressure molding, high-temperature firing and their significance.
 

A basic experience in the production of refractories is based on concentrates, which means high purity. The content of flux impurities has a great influence on the slag resistance and high temperature strength of furnace lining bricks. And directly affect the life of the furnace lining.

The purpose of high pressure molding is to increase the strength and density of the product. The higher the density of the brick, the more difficult it is for slag to penetrate the brick.
 

High-temperature firing is a measure taken to achieve sufficient sintering on the basis of high-purity raw materials. The so-called direct bonding structure can be formed in the brick under the condition that the liquid phase is very few, and the density of the product can be increased, and the high temperature strength of the brick can be improved.

It should be said that the improvement of the high-temperature strength of bricks is a comprehensive result of factors such as reduced impurity content, high-pressure molding, and high-temperature firing. Tests and experience show that the high temperature strength of the brick can predict the brick's ability to resist scrap wear.
