Product Description
High aluminum brick is made of high aluminum vanadium soil with a certain amount of clay combined with aluminum content from 46% to 80% of aluminum silicon series refractory brick, has excellent compressive strength and anti-spalling performance, while high aluminum brick is a neutral resistant material product, so the slag resistance and acid and alkali corrosion resistance is particularly outstanding. It can be used in non-metal smelting furnace, ladle, cement rotary kiln, lime kiln, waste incinerator, heating furnace and other industrial furnaces.
