Graphite products have been widely used in industrial sectors such as metallurgy, machinery, electrical, chemical, textile, and defense because of their many excellent properties.
Two important changes in the graphite refractory industry are the widespread use of magnesia carbon bricks in steelmaking linings and the application of aluminum carbon bricks in continuous casting. One of the main uses of graphite is in the production of refractory materials, including refractory bricks. , crucible, continuous casting powder, mold core, mold, detergent and high temperature resistant materials.
Graphite products are currently used in large quantities in the world for magnesia carbon bricks, and have become a traditional use of graphite. Conventional graphite clays are made of flake graphite with a carbon content greater than that of graphite, which is currently produced in foreign countries. Important improvements in technology.
The type of graphite used, the size and quality of the graphite have greater flexibility. Secondly, the traditional clay graphite crucible is replaced by silicon carbide graphite crucible. The products are increasingly used in mining systems, diesel systems, railway systems and high-tech. industry.
Graphite particles are mainly derived from the scraps generated during the machining of graphite electrodes and the waste products generated by the graphitization process. They are one kind of graphite products. Because graphite scraps have electrical conductivity, thermal conductivity, high temperature resistance, low ash content and high carbon content. It has a good chemical stability and is widely used as a recarburizer for steelmaking furnaces.
The combination of domestic graphite column and self-produced wear-resistant plate technology has made outstanding contributions to the development of China's automobile industry, greatly improving the production efficiency of automobiles, and lowering the cost of automobiles. It is used in guide bushes, guide columns and self-control. Lubricating the graphite column on the bearing and wear plate, the graphite product can also be made by carbonizing the carbon refractory material in a resistance furnace at 2500 ° C ~ 2800 ° C to make it graphitized.
Graphite products can be used as reaction tanks and autoclave linings in the chemical industry. They are also widely used in the manufacture of corrosion-resistant heat exchangers and masonry high-temperature furnaces. Graphite has a high scattering cross section and a very low thermal neutron absorption cross section. The high scattering cross section is used to slow down the neutrons, the low absorption cross section prevents the neutrons from being absorbed, allowing the nuclear reactor to achieve critical or normal operation with a small amount of fuel, which is used in graphite materials for the nuclear industry.
