Product Description

 

Description of Magnesia Chrome refractory Brick

Magnesia Chrome refractory Brick are refractory products containing magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main components, and periclase and spinel are the main mineral components. This type of brick has high refractoriness, high temperature strength, strong resistance to alkaline slag, excellent thermal stability, and certain adaptability to acidic slag.

Instructions for use of Magnesia Chrome refractory Brick

Magnesia Chrome refractory Brick are mainly used in metallurgical industries, such as the construction of open hearth furnace roofs, electric furnace tops, furnace refining furnaces, and various non-ferrous metal smelting furnaces. The high temperature part of the ultra high power electric furnace wall is made of fused cast Magnesia Chrome refractory Brick. The high erosive area of the refining furnace outside the furnace is made of Magnesia Chrome refractory Brick made of synthetic material. 

 

Features of Magnesia Chrome refractory Brick
The refractoriness is greater than 2000 ℃, the softening temperature under load is generally above 1550 ℃, the high temperature volume stability is good, and the rapid cooling and heating resistance is good.

Application field of Magnesia Chrome refractory Brick


Mainly used for cement rotary kiln, glass kiln regenerator, steelmaking furnace lining, refining ladle permanent layer, non-ferrous metallurgical furnace, lime kiln, mixing furnace and refractory high temperature furnace lining, etc.; also used for open hearth furnace top, electric furnace Furnace top, refining furnace outside the furnace.

 

Classification of Magnesia Chrome refractory Brick

(1) Ordinary Magnesia Chrome refractory Brick

(ie silicate combined Magnesia Chrome refractory Brick), this kind of brick is made of chrome ore and magnesia with more impurities (SiO2 and CaO). The firing temperature is not high, around 1550°C. 

(2) Directly bonded Magnesia Chrome refractory Brick

are made of chromium concentrate with low impurity content and relatively pure magnesia. The firing temperature is above 1700°C. The structural feature of this kind of refractory brick is that the refractory crystal grains are mostly in direct contact.

(3) Recombined Magnesia Chrome refractory Brick

are combined with Magnesia Chrome refractory Brick. Magnesia Chrome refractory Brick made from artificial synthetic raw materials co-sintered magnesia chromium materials or fused magnesia chromium materials (or partly fused magnesia) are called recombined Magnesia Chrome refractory Brick.

(4) Semi-recombined Magnesia Chrome refractory Brick

which are made of artificial synthetic raw materials as granules, and chromium concentrate and magnesia as fine powder, should be called semi-recombined magnesia-chrome bricks. 

(5) Casting Magnesia Chrome refractory Brick

are made of magnesia and chrome ore with a certain amount of additives, mixed, compacted and bisque-fired, broken into pieces, melted in the electric arc furnace, injected into the mold, and annealed to produce master bricks
