rp 700 mm graphite electrode

The rp 700 mm graphite electrode is used in the atomic energy industry and the national defense industry. The rp 700 mm graphite electrode has good neutron deceleration performance. It was originally used as a moderator in atomic reactors. The uranium-graphite reactor is one of the most widely used atomic reactors. The deceleration material used in nuclear power reactors should have high melting point, stability and corrosion resistance. Graphite can fully meet the above requirements. The purity of graphite used in atomic reactors is very high, and the impurity content should not exceed tens of ppm (ppm is one part per million), especially the boron content should be less than o.sppm.

Graphite is also used in the defense industry to manufacture solid fuel rocket nozzles, missile nose cones, spare parts for aerospace navigation equipment, heat insulation materials and radiation protection materials. Graphite can prevent boiler fouling. Experiments have shown that adding a certain amount of graphite powder to the water can prevent scaling on the boiler surface. In addition, metal chimneys, roofs, bridges and pipes are coated with graphite to prevent corrosion and rust. Including refractory bricks, crucibles, continuous casting powder, casting cores, casting detergents, high temperature resistant materials, etc. In the past 20 years, two important changes in the refractory industry have been the wide application of magnesia-carbon bricks in steelmaking furnace linings and the application of aluminum-carbon bricks in continuous casting.

Graphite and other impurities can be used as carburizing agents in the steelmaking industry. Carburizing uses a variety of carbon materials, including synthetic graphite, petroleum coke, metallurgical coke and natural graphite. Graphite is still one of the main uses of clay graphite in steelmaking in the world.
