Graphite rod

Graphite rods. High-purity graphite rods have excellent physical and chemical properties, so they are widely used in chemical industry, electronics, machinery, metal smelting and other industries. Carbon steel pole. Graphite columns have many uses. 1. Refractory materials. Due to the heat-resistant and high-strength properties of graphite rods and products, they are mainly used in the manufacture of graphite crucibles in the metallurgical industry. In steelmaking, graphite is often used as a protective agent for steel ingots and linings for metallurgical furnaces. 2. As refractory filler. A graphite rod composite interlayer compound prepared by chemical or electrochemical treatment method, the preparation method is expandable graphite rod. When the graphite rod is heated, its volume expands rapidly to suffocate the flame and expand, thereby achieving the effect of isolating the flame, delaying or interrupting the spread of the flame, and it is non-combustible, with good flexibility, high surface energy, and good strength of the carbonized layer. 3. Anti-corrosion material. The electrode has good chemical resistance and solvent corrosion resistance. If chemical pigments such as zinc yellow are added to the formula, its anti-rust effect will be better; the anti-rust primer made of carbon black, talcum powder, oil, etc. has excellent anti-corrosion performance. 4. As a conductive material. In the electronics industry, it is used to manufacture electrodes, electric brushes, carbon rods, carbon tubes, positive electrodes of mercury positive flow devices, ink gaskets, telephone components, TV picture tube coatings, and so on. 5. Used as a wear-resistant lubricating material. In the mechanical industry, graphite rods are often used as lubricants and can be used under high-speed, high-temperature and high-pressure conditions. 6. Castings, foundry, dies and high-temperature metallurgical materials: Because graphite rods have a small thermal expansion coefficient and can withstand rapid cooling and rapid heat changes, they can be used as glassware casting molds. After graphite treatment, the castings have accurate dimensions and smooth surface yields. High, can be used without machining or slight treatment, so a lot of metal can be saved.
