Silicon carbide refractory products

     Silicon carbide refractories with silicon carbide particles or powder as a raw material. Added binder (clay or ferrosilicon, quartz, etc.) is made, or without a binding agent with high-temperature recrystallization into the legal system.

     Clay as binding agent silicon carbide products, including SiC 35% ~87%, Si02 10% ~50%, Al3O2 3% ~30%, load softening starting temperature of 1400~1620 ℃.

     2300 ℃ obtained by melting recrystallization silicon carbide products, including SiC 99%, a bulk density of 2.55g / cm3. Product has a high thermal conductivity, high resistance to thermal shock. Wind from the quenching temperature, repeated up 50~150 times. high temperature chemical stability and wear resistance are good, but expensive, in the range of 900~1100 ℃ easily oxidized. Products more compact, better oxidation resistance. Used to do furnace lining, muffle furnace wall refractory heating plate, sagger, kiln push plate moved into plate and heating elements (silicon carbide) and the like.

     The use of silicon carbide with a corrosion-resistant, high temperature strength, good thermal conductivity, impact resistance and other characteristics, on the one hand can be used for a variety of silicon carbide smelting furnace lining, high temperature furnace components, silicon carbide plate, lining, supports, sagger , silicon carbide crucible.

     On the other hand it can be used for high-temperature indirect heating material non-ferrous metal smelting industry, such as Vertical Retort furnace, distillation furnace trays, aluminum cell, copper melting furnace lining, zinc furnace arc plate, thermocouple protection tubes, etc. ; for the production of wear-resistant, corrosion resistance, high temperature and other advanced silicon carbide ceramic material; also making rocket nozzles, turbine blades. In addition, silicon carbide is the highway, one of the ideal material for solar water heaters and other aviation runway of.
