Description

Silicon Nitride Heater Protection Tube
Because of its superior high strength, thermal shock resistance and corrosion resistance, silicon nitride ceramic has become the first choice for the heater protection tube of aluminum casting furnaces, especially holding furnace. Its comprehensive performance and service life are also the best of all available materials.

Advantages:
1.Silicon nitride ceramics are excellent in heat resistance, so our products can withstand the heat load of high temperature heating elements.
2.Its strong thermal shock resistance ensures that the protection tube will still work for a long time when the aluminum liquid heats up and cools down and the temperature difference between the heating element and the aluminum liquid. Therefore, plugging and unplugging will not affect performance during batch operation.
3.The superior corrosion resistance makes the eluted contaminants not enter the molten aluminum liquid, thereby maintaining the purity of the aluminum liquid.
4.Low wettability to molten aluminum, easy to maintain and operate.
5.Silicon nitride ceramics have excellent high temperature resistance and high temperature mechanical strength, and can withstand the heat load of high temperature heating elements.
6.The non-wetting property of molten aluminum liquid can greatly reduce the adhesion of slag on the surface of the protection tube, which is convenient for maintenance and operation.
7.Excellent insulation to ensure good insulation between the heating element and the aluminum liquid.
8.The superior corrosion resistance and wear resistance of silicon nitride ceramics can protect the internal heating element for normal operation for a long time, and the practical application proves that the operating life can exceed 1 year.

MANUFACTURING PROCESS:
Granulation - Extrusion Forming - Semi-finished Processing - Sintering - Grinding and Polishing- Quality Inspection and Test.
