Application of graphite products |
1. Used as refractory material: Graphite and its products have the properties of high temperature resistance and high strength. It is mainly used in the metallurgical industry to make graphite crucibles. In steelmaking, graphite is often used as a protective agent for steel ingots and as an inner lining of metallurgical furnaces.
2. As a conductive material: used in the electrical industry to manufacture electrodes, brushes, carbon rods, carbon tubes, positive electrodes of mercury positive current devices, graphite washers, telephone parts, and coatings for television picture tubes, etc.
3. As a wear-resistant lubricating material: graphite is often used as a lubricant in the machinery industry. Lubricating oil is often not used under high-speed, high-temperature, and high-pressure conditions, while graphite wear-resistant materials can work at high sliding speeds at a temperature of 200 to 2000 ℃ without lubricating oil. Many equipment that transports corrosive media widely use graphite materials to make piston cups, seals and bearings. They do not need to add lubricating oil when they are running. Graphite emulsion is also a good lubricant for many metal processing (wire drawing, pipe drawing).
4. Graphite has good chemical stability. Specially processed graphite, which has the characteristics of corrosion resistance, good thermal conductivity, and low permeability, is widely used in the production of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, and filters , Pump equipment. It is widely used in petrochemical industry, hydrometallurgy, acid-base production, synthetic fiber, papermaking and other industrial sectors, which can save a lot of metal materials.
Using Instruction :
1.Avoid contacting of hot molten metals with water, oil, grease, etc. It may cause excessive spatter and burns.
2. Do not uses in flammable vapors or dust, a fire or explosion may happen.
3. Avoid looking directly at the light of the reaction. It may irritate your eyes.
4. Wear safety glasses and leather gloves to use the graphite molds.
5. void fire, graphite molds / products must be stored in dry, well-ventilated area, away from open flame and excessive heat.

About High purity graphite ring |
Because the High purity graphite ring is made of the same material, the performance of the material is uniform in all parts of the seal ring, there is no defect of leakage and separation of the combined seal ring, and there is no possibility of electrochemical corrosion. Most of the soft rings are made of graphite, and various alloy steels such as bearing steel (GCr9), high-speed steel (W18Cr4V) and other alloy steels (such as 1140Cr, 3Cr13, etc.) can be used in the manufacture of hard rings, and some alloy cast irons are also used.
