Also, we have SK30, SK32, SK34, SK35 refractory clay bricks to choose. Their aluminum content is lower than high alumina bricks, and the use temperature is lower, but the price is cheaper. If your kiln is not demanding, you can also choose refractory clay bricks.
Applications:
1. Furnaces of metallurgy industry, heat treatment furnace.
2. Furnaces of chemical industry and construction industry.
3. Furnace of incineration of garbage, recirculating fluidized bed furnace.
Standard size:
230x114x65mm. This product can be customized on color, size and shape, ect. Welcome to OEM and ODM.
