High-performance silicon nitride ceramic materials developed for the aluminum industry has significantly improved thermal and mechanical properties than similar products. On this basis, the "L-shaped high thermal conductivity submerged heating "Appliance" will bring revolutionary progress to aluminum industrial equipment.
Silicon nitride ceramic has become the material of choice for the outer protection tube of electric heaters and gas heaters due to its excellent high temperature performance.
Due to its good high-temperature strength and high thermal shock resistance, the product can withstand the thermal load of the high-temperature heating element or burner for a long time, and the service life is more than one year;
Advantage:
Compared with the traditional upper radiant heating method, the energy saving efficiency reaches 20%-30%, and the overheating and oxidation of the upper aluminum liquid is effectively avoided.
Silicon nitride ceramics hardly react with the molten aluminum, so it will not pollute the molten aluminum, which is beneficial to maintain the purity of the heated molten aluminum;
