graphite electrode for lf

Consumption analysis of graphite electrode for lf during the steelmaking process In the process of steelmaking, graphite electrode for lf will produce some consumption, which can be divided into normal consumption and extraordinary consumption. In normal consumption, there are arc consumption, chemical consumption, and oxidation. Consume three kinds, although they cause loss to the graphite electrode for lf, but there are differences in the way.

1. Arc consumption is again called evaporative consumption, because there will be a high temperature of up to 3000 ℃ between the electrode and the charge, and there will be continuous consumption of the graphite electrode for lf, which accounts for about 40% of the normal consumption.

2. Chemical consumption refers to the reaction between the electrode and some impurity iron, calcium, and manganese oxides in the steel or the reaction with the iron in the molten steel. This consumption is also the quality of the steel and the diameter of the graphite electrode for lf. There is a direct relationship.

3. Oxidation consumption refers to the consumption caused by the reaction with oxygen in the process of steelmaking. It is related to the atmosphere, gas temperature and gas flow rate in the furnace. It is found in the normal consumption of 50%-60%, which is the largest consumption. of.

4. Extreme consumption is the breakage of the machine when it is used at abrasion level.
