Protective tubes for pyrometers - Import export

The protective tube of silicon nitride material has high thermal conductivity, high temperature resistance, corrosion resistance,non-wetting with molten metal, and electrical insulation, making it the best choice for heating body protection tubes. The advantage of the immersion holding furnace is very obvious, and in order to achieve the immersion of the heating element into the molten metal, it is necessary to have a protective tube which can protect the heating element well. Silicon Nitride (Si3N4) Characteristics: 1 Good thermal shock resistance 2 Creep resistance 3 Low density 4 High fracture toughness 5 High hardness and wear resistance 6 Electrical resistivity
