Clay brick Clay brick is composed of fireclay as raw material. It is noted for low creep, superior refractoriness, thermal shock stability, high extrusion pressure, lower moisture water content, high production capacity and greater intensity of wet bricks . It is suitable for producing Multi-hole bricks, hollow bricks and solid clay bricks with different sizes. It is used in hot blast stove, regenerator , partition wall and so on ,such as clay refractory bricks for blast furnaces,clay insulation brick ,fire-clay insulating refractory brick ,clay refractory bricks for casting , clay refractory bricks for steel casting in the ladle , clay refractory bricks for steel ladle linings, dense fireclay brick, clay refractory bricks for glass furnace, low porosity clay refractory bricks for glass furnace,low creep fire clay brick, phosphate immersed clay refractory bricks for blast furnaces and so on.
