Black Carborundum Applications:
●The application in the non-ferrous metal smelting industry
Use black carborundum’s high temperature, strength, good thermal conductivity and impact resistance, for high-temperature indirect heating materials, such as distillation furnace trays, aluminum tanks, copper melting furnace linings, zinc furnace arc plate, thermocouple protection tubes.
●The application in the iron and steel industry
Use black carborundum’s corrosion-resistance, thermal shock resistance to abrasion and good thermal conductivity for increasing service life of large-scale blast furnace lining.
●The application in the metallurgical ore processing
Black carborundum with strong wear resistance, second only to the diamond hardness, is the ideal material for wear-resistant pipe, impeller, pump chamber, cyclone and ore bucket lined, also for the aviation runway. The wear resistance is 5-20 times of cast iron, rubber life.
●The application in the building materials ceramic and grinding wheel industry
Use its characters of thermal conductivity, heat radiation and high temperature strength to make sheet kiln. It can not only reduce the kiln capacity, but also improve furnace installed capacity and product quality and shorten the production cycle. It is also the ideal indirect materials of sintering ceramic glazed baked.
●The application in energy saving
Use its good thermal conductivity and thermal stability to make heat exchanger, saving 20% fuel consumption and 35% fuel and improving the productivity by 20-30%. In particular, mine processing plant with a discharge pipeline in place, the abrasion resistant material is 6-7 times more than common.
