Hebei ultra-high power graphite electrode for arc furnaces manufacturers
The temperature of molten salt electrolysis of graphite products is generally below 1000 degrees Celsius. Graphitized anodes are generally used as anode conductive materials for electrolyzers producing alkali and salt solutions. Graphitized electrodes are also used to produce conductive materials for the furnace head of the resistance furnace used in the production of emery (silicon carbide). In addition to the above uses, carbon and graphite products are widely used as conductive materials in the motor manufacturing industry as slip rings and brushes. They are also used as carbon rods in dry batteries, searchlights or arc carbon rods for arc generation, and anodes in rectifiers.

Varieties of graphite electrode. Electric arc steelmaking furnaces are generally divided into three categories, namely ordinary power electric furnaces, high-power electric furnaces and ultra-high-power electric furnaces. Corresponding to the power level of electric furnace steelmaking, graphite electrode is also divided into 3 varieties accordingly, namely ordinary power graphite electrode (code RP grade), high power graphite electrode (code HP grade) and ultra high power graphite electrode (code UHP grade) ). The nominal diameter of the electrode varies from 75mm. The physical and chemical functions of high-power and ultra-high-power graphite electrodes are better than those of ordinary power graphite electrodes, such as low electrical resistivity, large volume density, high mechanical strength, low linear expansion coefficient, and excellent oxidation resistance.
Graphite has outstanding chemical stability. The specially processed graphite has the characteristics of corrosion resistance, good thermal conductivity, and low permeability. It is used to make heat exchangers, response tanks, condensers, combustion towers, absorption towers, coolers, heaters, and filters. , Pump equipment. It is widely used in petrochemical industry, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, which can save a lot of metal materials. Graphite can also prevent boiler fouling. Tests by relevant units indicate that adding a certain amount of graphite powder (approximately 4 to 5 grams per ton of water) can avoid boiler fouling. In addition, graphite coating on metal chimneys, roofs, bridges, and pipes can prevent corrosion and rust.

Why is graphite used to make electrodes? About electrodes should be seen everywhere in our daily life, but we may not be familiar with why we choose graphite as the main material. This is because graphite has some useful properties that make it ideal as an electrode in a variety of applications, such as the production of arc steel. Furthermore, graphite is cheap, rich, stable under various operating conditions, expandable, durable/hard, and has outstanding electrical and thermal conductors (a lot of heat occurs in the production of arc steel).
What are the advantages and disadvantages of copper electrode and graphite electrode in electrical discharge machining? Advantages and Disadvantages of Red Copper Electrode Red copper has a wide range of origins, has excellent conductivity, can be processed stably under difficult conditions, is not prone to arcing, and has low processing loss; higher accuracy can be obtained, and the selection of precision processing can achieve better than Ra1. Surface roughness of 25μm. The machining process can maintain sharp edges and corners and fine shapes. Disadvantages: The mechanical processing function is not as good as graphite, and the grinding is difficult; the mechanical strength is low, which is not conducive to the clamping, correction and the maintenance of stable processing for a long time; the ratio is serious, that is, it increases the burden of the processing feed system and improves The requirements for the system are not conducive to the installation and calibration of electrodes.
