Black silicon carbide raw materials (quartz sand, petroleum coke, silica, etc.) are mixed according to a certain proportion, and then sent to the resistance furnace for high temperature smelting, and the finished product is silicon carbide block after smelting. Crushing: silicon carbide hardness is high, between white corundum and diamond, and the block is relatively large, ordinary crusher is difficult to crush it, need to first use the jaw crusher for rough crushing. Fine crushing: After coarse crushing of silicon carbide, it is necessary to use a cone crusher for fine crushing, and the cone fine crusher can crush silicon carbide into a variety of specifications.
Screening: The fine silicon carbide particle size screening, screening into different particle size of silicon carbide sand.
We are professional black silicon carbide manufacturer for customers in different industries and countries according to FEPA, JIS, GB, ISO, ANSI & P standard. 0-1mm, 1-3, 3-5mm etc. for refractoriness, FEPA F sizes for bonded abrasives aluminum oxide tools, FEPA P sizes for coated abrasives silicon carbide products.

Black Silicon Carbide Applications:
●The application in the non-ferrous metal smelting industry
Use black silicon carbide’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 silicon carbide’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 silicon carbide 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.
