Insulating firebricks HS

High-temperature mullite insulation bricks

High-temperature mullite insulation bricks are imported new technology, using high-purity hot-mullite clinker. Depending on the temperature, add a filler made of alumina in line with burn products, high temperature firing, direct synthesis of mullite phase in energy-efficient material that can be direct contact with flame.By the relevant units of the current use of the product to achieve a variety of similar products abroad, technical indicators, advanced furnace must use new materials, new material is a high-temperature insulation refractory mullite.
