Hopper High Alumina Refractory Brick Unshape Brick for Iron and Steel Industry
The Description:
Clay brick for ingot casting refers to the clay brick commonly used in the whole process of introducing molten steel from the steel drum to the ingot mold. It includes steel drum lining bricks and steel casting bricks (in which sleeve bricks, plug bricks, water position bricks, seat bricks, shaped pipe bricks, management center cast pipe bricks, management center bricks, flow steel bricks, flow steel tail bricks, ingot mold bottom bricks). The initial key selection of plastic method (moisture 16-20%) production of ingot clay brick. After the 1950s, marketing promoted the semi-dry production of ingot clay bricks. Compared with the two production and manufacturing methods, the semi-dry production and manufacturing process is less, the high temperature characteristics of handicrafts are good, the specifications are accurate, and the production and manufacturing cost is low, so the semi-dry production and manufacturing of ingot clay bricks are selected all over the world.
