Refractory fire Brick For Metal Mixer And Ladle Of Iron

Refractory fire Brick For Metal Mixer And Ladle Of Iron

Refractory fire bricks are an essential component in the construction of linings for metal mixers and ladles used in iron and steel production. These bricks are designed to withstand high temperatures, thermal shock, and the corrosive effects of molten metal.

What Kind of Unshaped refractory materials for Iron Industry?

TypesUnshaped refractory materialsIntroduction
Type 1Alumina Silicon Carbide BrickThese bricks are commonly used in areas of furnaces and other high-temperature applications where harsh conditions and temperature fluctuations are present.
Type 2Chrome-Containing Phosphate High Alumina BrickThey are often used in areas of furnaces where there is exposure to aggressive slag or high-temperature environments.
Type 3Unfired BrickThey are in a raw, unburnt state and are typically shaped and dried but not fired in a kiln.

Type 1:Alumina Silicon Carbide Brick

Alumina Silicon Carbide (AlSiC) bricks are composed of high alumina and silicon carbide. This combination results in a brick with excellent thermal shock resistance, high temperature strength, and resistance to wear.

Type 3:Unfired Brick

Unfired bricks, also known as green bricks, are refractory bricks that have not undergone the firing process. They are in a raw, unburnt state and are typically shaped and dried but not fired in a kiln. These bricks require careful handling and proper firing during installation to achieve the desired properties. Once fired, they undergo a transformation and acquire the necessary strength and resistance for use in high-temperature applications.
