Quick Details
Specifications
Silicon Nitride Heater Protection tube
Good casting will be depend on temperature control.For optimum pouring temperature of molten metal,heater will be used for steady temperature.Silicon nitride heater protection tube will not only protect the heater,but also make rapid and uniform heating of molten metal during casting.
Usually immersion heater will be used in non-ferrous metallurgy due to the corrosion resistance,fast heat conductivity of silicon nitride.
No matter electricity or gas heating,the efficiency is higher and service life is long.
