Magnesium and Magnesia-based Refractory Bricks
Magnesium magnesium silicate refractory bricks are refractories with magnesium and magnesium-silicate as main raw materials. They are widely used in metallurgical, chemical and other industries. This paper introduces the structure and performance of magnesium and magnesium-silicate refractory bricks.
Magnesium magnesium silicate refractories are generally composed of basic oxide, transition oxide and auxiliary oxide, with magnesium oxide as the main component, which determines their outstanding high temperature performance. The basic oxide has functions such as bearing load and corrosion resistance, the transition oxide has functions such as binding, gelatinization, etc., and the auxiliary oxide has functions such as lubrication and stabilization of the slag. Therefore, the composition and type of oxide have a great influence on the performance of magnesium and magnesium silicate refractories.
In terms of performance, magnesium and magnesium silicate refractory bricks have excellent high temperature properties, especially their high temperature strength is good. The higher the content of magnesium oxide and the higher the transition oxide content, the higher the high temperature strength of the brick. In addition, they have good thermal shock resistance, corrosion resistance, slag resistance and erosion resistance. Magnesium and magnesium silicate refractory bricks also have the advantages of large refractoriness, long service life and strong air adaptability.
In addition, magnesium and magnesium silicate refractory bricks have unique physiological and biochemical properties. They have high new heat strength and good slag erosion resistance. In addition, their insulation properties are also very good, which can ensure the stability of the furnace.
In summary, magnesium and magnesium silicate refractory bricks have many advantages, such as high temperature strength, thermal shock resistance, corrosion resistance, slag resistance and erosion resistance, etc. They are widely used in metallurg y, chemical industry and other industrial fields.
