Product Application

1. 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 a lining for metallurgical furnaces.

2. Used for processing and manufacturing electric heating elements, precious metal casting molds, smelting metals and other graphite crucible boats, dishes, single crystal furnaces; used for heaters, electric spark graphite, sintering molds, electron tube resistance anodes, metal coating, semiconductor technology Graphite molds; graphite products such as graphite electrodes for emission electron tubes, thyratrons and mercury arc distillers are mainly used in various vacuum resistance furnaces, induction furnaces, sintering furnaces, brazing furnaces, ion nitriding furnaces, tantalum-niobium smelting furnaces, Special graphite plates for vacuum quenching furnaces, graphite boats, graphite tubular heating elements, conductive rods, graphite hearth plates, graphite bolts, nuts, graphite brackets, graphite molds

3. As a conductive material, used in the electrical industry to make electrodes, brushes, carbon rods, carbon tubes, positive electrodes of mercury positive current devices, graphite washers, telephone parts, and coatings for television picture tubes.

4. Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000℃. It is easy to oxidize at high temperatures. Except for vacuum, it can only be used in a neutral or reducing atmosphere. Its thermal expansion coefficient is small, thermal conductivity is large, resistivity is (8~13)×10-6 Ω•m, processability is better than SiC, MoSi2 rod, high temperature resistance, extreme cold and extreme heat resistance, good price Cheaper.

5. Graphite blocks are used for silicon carbide furnaces, graphitization furnaces and other metallurgical furnaces, resistance furnaces as furnace lining and conductive materials, and impermeable graphite heat exchangers. It is widely used in various fields such as electronics, metallurgy, chemical industry, steel and so on. The products have excellent quality and stable performance. Graphite blocks are used as conductive electrodes in the electrolytic magnesium, electrolytic nickel and other industries. Graphite blocks are also widely used to make corrosion-resistant heat exchange equipment in the chemical industry and materials for high-temperature furnaces.
