Description:

Good casting will be depend on temperature control. For pouring temperature of molten metal , heater will be used for steady temperature . Silicon nitride heater protection tube will not only protect the heater 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.

Feature:

1.High strength & good compactness

2.low thermal expansion coefficient

3.Excellent thermal shock resistance

4.No wetting by molten aluminium and other non-ferrous molten metal

5.Good corrosion resistance

Application:

Silicon Nitride heater protection tube is used in molten aluminum, high oxidation resistance, high-speed and efficient dispersal and removal of hydrogen and other unwanted particles, long service time.
