Lable Slag Line Refractory Brick
Due to different working conditions, the firebrick used in the working layer is slightly different. Ladle slag is a thermal equipment for loading and transporting molten steel, and its internal environment is subdivided into impact area, bottom area, wall area and slag line area. As is known to all, the refractory bricks used in different parts of the kiln with different materials, but the refractory bricks used in steel lable is magnesium-carbon brick. Ladle slag line refractory brick is high grade magnesia carbon brick.

Feature of Lable Slag Line Refractory Brick
. goodresistance to slag corrosion.
. good high temperature performance.
. good anti-stripping.
. long service life.
The ladle slag line area is the worst condition of the lining of the ladle lining. It is in the high alkaline slag erosion area, severe temperature changes and mechanical impact of the molten steel. Therefore, there is a much higher requirement for the refractory brick used in the slag line area. The raw material for the use of magnesia carbon brick for ladle is magnesia, which has high corrosion resistance and combines with carbonaceous graphite to better resist slag and molten steel erosion in high temperature environments.
With the development of the steel business, the ladle slag line used firebrick and integral with the ladle refractory brick from steel mills to refractory manufacturer contract, can improve the efficiency of ironmaking, reduce the costs of ladle refractory material used by steel mills spending, revell refractory can provide ladle with firebrick contracting services, solve the ladle refractory materials for you.
