Reasons for High Power Consumption of Electric Arc Furnace Steelmaking


The reasons for the high power consumption of electric arc furnace steelmaking are rough as follows.

Raw Material Conditions

For the scrap steel used in electric furnace steelmaking, since the raw materials are required to use light and thin materials, briquettes, etc., it is often easy to cause high material feed and thermal shutdown, resulting in large heat loss. 

In the case of insufficient charging once, a second feeding is required. In some cases, there have been three feedings, which also increases the heat loss. Each additional charging (the average charging time is 5min) increases the power consumption by about 7-12KWh/T. 

In addition, it is found that C and P are relatively high after the raw materials are purified. 

After entering the oxidation period, the removal of C and P will require a longer time and higher energy consumption.

Operator Skills

The power consumption during the melting period accounts for 60%-70% of the total power consumption, and the power is mainly wasted after the chemical cleaning. energy.

Objective Conditions

During the smelting process, due to the shortage of electric power, the phenomenon of power outage occurs suddenly. After a long time, the molten steel cools and solidifies and needs to be remelted. This process wastes a lot of electric energy.

Other Accidents

If the operator does not operate properly, the electrode will be broken, and a lot of heat will be lost in the process of processing the electrode. 

When the reduction sample is taken in the reduction period, it is found that the composition is unqualified, and the secondary oxidation must be carried out, which will also waste a lot of money. thermal energy. 

During the smelting process, the coal-oxygen burner leaks water, which interrupts the fluxing; when the furnace wall is hung with materials, the furnace cover needs to be unscrewed for processing, which delays the smelting time to varying degrees and increases the heat loss.
