Embedded slag type structure of heating element electrodes of electromagnetic induction slag smelting furnace

Abstract

The invention relates to an embedded slag type structure of heating element electrodes of an electromagnetic induction slag smelting furnace. The embedded slag type structure of the heating element electrodes of the electromagnetic induction slag smelting furnace is characterized by comprising four graphite heating element electrodes, four fixing plates and sixteen fixing bolts, wherein the graphite heating element electrodes are inserted into a furnace bottom lining and are firmly fixed in the furnace bottom lining through the fixing plates and the fixing bolts. In the working process, an induction coil is electrified, the graphite heating element electrodes induce heat and enable slag to be melt, and due to the fact that the positions of the graphite heating element electrodes are located under the slag liquid level all the time in the whole course of heating and melting the slag, the graphite heating element electrodes are oxidized but are small in loss. The embedded slag type structure of the heating element electrodes of the electromagnetic induction slag smelting furnace has the advantages that the problems of oxidization and burning loss of the electromagnetic induction graphite electrodes are effectively solved; the electromagnetic induction slag smelting furnace is high in power factor, low in energy consumption, and high in temperature rise speed; the energy consumption is low, the heat efficiency is high, the waste slag amount is small, the fiber forming rate is high, and the cost advantage is obvious; the smelting furnace has the advantages of saving energy, lowering cost, and being short in flowing path, high in quality and efficient.

Description

technical field [0001] The invention relates to a slag-embedded slag-type structure for a heating element electrode of an electromagnetic induction slag melting furnace, and belongs to the technical field of slag melting equipment. Background technique [0002] The process energy consumption of blast furnace ironmaking accounts for about 60% of the total energy consumption of the iron and steel industry. Blast furnace slag is a kind of solid waste discharged from blast furnace ironmaking. Its treatment process not only consumes a lot of energy, but also discharges a lot of harmful substances. Therefore, it is necessary to carry out research on the recycling of blast furnace slag, which is an industrial solid waste. The slag discharged during the blast furnace ironmaking process, also known as blast furnace slag, can be divided into steelmaking pig iron slag, foundry pig iron slag, ferromanganese slag, etc. In some areas of China and the Soviet Union, titanium-magnetite is ...
