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.
The high-temperature strength of silicon nitride ceramics is very good, which ensures that the sealed tube can still be used for a long time under frequent operating conditions.In view of the brittleness of silicon nitride ceramics, large mechanical shocks should be avoided, so attention should be paid to the design and installation of the lifting transmission device.
Advantage:
The high density, high strength and high thermal shock resistance of silicon nitride ceramics determine that it is the best choice for sealing tubes in low pressure die casting.
Compared with aluminum titanate and alumina ceramics, silicon nitride has superior wear resistance, which can ensure the airtightness of the sealed tube for a long time;
