best graphite electrode uhp
The main application areas of best graphite electrode uhp
1. Used in electric arc steelmaking furnace. Electric furnace steelmaking is a big user of best graphite electrode uhp. The output of electric furnace steel in my country accounts for about 18% of the output of vinegar tanks, and the graphite electrode uhp for steelmaking accounts for 70% to 80% of the total amount of best graphite electrode uhp. Electric furnace steelmaking uses the best graphite electrode uhp to introduce current into the furnace, and uses the high temperature heat source generated by the arc between the electrode end and the charge to smelt. At present, the domestic consumption of best graphite electrode uhp per ton of electric furnace steel is 1.5-6kg. In 2004, the output of electric furnace steel in my country was 45 million tons, and the best graphite electrode uhp needed for electric furnace steelmaking was 150,000 to 200,000 tons.
2. Used in ore thermal electric furnaces. The submerged electric furnace is mainly used for the production of industrial silicon and yellow phosphorus. Its characteristic is that the lower part of the conductive electrode is buried in the charge to form an arc in the charge layer, and the heat energy from the resistance of the charge itself is used to heat the charge, which requires current High-density submerged electric furnaces need uhp graphite electrode. For example, each production of 1t of silicon consumes about best graphite electrode uhp, and every production of 1t of yellow phosphorus consumes about 40kg of best graphite electrode uhp.
3. For resistance furnace. Graphitization furnaces for the production of graphite products, melting furnaces for melting glass, and electric furnaces for the production of silicon carbide are all resistance furnaces. The materials in the furnace are both heating resistors and objects to be heated. Usually, the best graphite electrode uhp used for conduction is embedded In the furnace head wall at the end of the resistance furnace, the best graphite electrode uhp used here is discontinuously consumed.
4. Used to prepare special-shaped graphite products. The blank of best graphite electrode uhp is also used to process various crucibles, molds, boats and heating elements into special-shaped graphite products. For example, in the quartz glass industry, for every 1t of fused tubes produced, 10t of best graphite electrode uhp blanks are required; for every 1t of quartz bricks, the best graphite electrode uhp blanks are consumed.
