Consumption Analysis of Graphite Electrode in Steel Making Process

Time:2017-11-29 17:27

  Graphite electrodes in the steelmaking process will produce some consumption, which can be divided into normal consumption and very consumption, in the normal consumption of arc consumption, chemical consumption, oxidation consumption of three, although they cause wear and tear on the graphite electrode, but the way There are differences.

  1, the arc consumption has also become evaporation consumption, because the electrode and charge will produce up to 3000 ℃ high temperature, there will be a continuous consumption of graphite electrodes, accounting for about 40% of normal consumption.

  2, the chemical consumption refers to the electrode and some of the impurities of iron steel, calcium, fierce oxide reaction or reaction with the molten iron consumption, this consumption is also the quality of steel and graphite electrodes have a direct diameter Relationship.

  3, oxidative consumption refers to the consumption of oxygen produced in the process of steelmaking, and the furnace atmosphere, gas temperature, gas flow rate, found in the normal consumption of 50% -60%, is the largest consumption of.

  4, the consumption is the machine wear grade fracture and so on.
