We follow the quality of rest assured that the price of conscience, dedicated service. Silicon nitride ceramic has the best thermal conductivity when used for aluminum melting. It’s quick response to the temperature sensor in aluminum and other nonfrrous metals melting.
It has excellent shock resistance. Light weight make it easier to operate and maintain. It can be used for many years. Silicon Nitride Protect Tube for Thermocouples is mainly used in the production of aluminum, copper, and zinc, as the lining material of the molten pool and electrolytic bath (reduction bath).
