Graphite electrode usage

What is the allowable stress that the graphite electrode can withstand for the backing plate? How thick is the graphite plate generally, and what purpose is it used for; can it be used for sliding friction pads?

1) Refractory materials: In the smelting industry, graphite is used to make graphite crucibles, as a protective agent for steel ingots, and as magnesia-carbon bricks for the lining of smelting furnaces.

2) Conductive materials: In the electrical industry, graphite electrodes, electric brushes, electric rods, carbon tubes and coatings for television picture tubes are widely used.

3) Wear-resistant materials and lubricants: In many mechanical equipment, graphite is used as a wear-resistant and lubricating material, which can slide at a speed of 100m/s within the temperature range of -200 to 2000°C without or using less lubricating oil.

4) Sealing materials: Flexible graphite is used as piston ring gaskets and sealing rings for centrifugal pumps, water turbines, steam turbines and equipment that transport corrosive media.

5) Corrosion-resistant materials: Graphite is used as utensils, pipes and equipment, which can resist corrosion of various corrosive gases and liquids. It is widely used in petroleum, chemical, hydrometallurgical and other sectors.

6) Heat insulation, high temperature resistance and radiation protection materials: Graphite can be used as a neutron retarder in nuclear reactors, as well as nozzles of rockets, nose cones of missiles, aerospace equipment parts, heat insulation materials, radiation protection materials, etc.
