Electromagnetic induction heater can quickly convert electrical energy into heat energy, and the heat energy is mainly transferred through the self-sensing heating method inside the ore, so that the iron ore can quickly reach the required high temperature. Compared with the traditional heating method, electromagnetic induction heating is faster and can improve production efficiency.

The actual application of electromagnetic heating in the iron ore site mainly involves two aspects: ore pretreatment and smelting process. The following are the practical applications of electromagnetic heating in these fields:

I. Ore pretreatment:

1, drying: electromagnetic heating can be used in the drying process of ore. By converting electromagnetic energy into thermal energy, it rapidly heats up the ore to make its internal moisture evaporate and accelerate the drying speed.

2, crushing and grinding: electromagnetic heating can be applied to the crushing and grinding process of ore. The ore is subjected to alternating electromagnetic force in the electromagnetic field, which increases the collision frequency between particles, thus improving the crushing and grinding efficiency.

Second, smelting process:

1, smelting: electromagnetic induction heating is used in the smelting process of iron ore. In electromagnetic induction heating, by introducing high-frequency current into the iron ore in the smelting container, electrical energy is converted into thermal energy, which rapidly heats the iron ore to the melting point and realizes smelting.

2, pre-furnace heating: electromagnetic induction heating can be used for pre-furnace heating of iron ore in the smelting process. Through the iron ore into the smelting furnace before the electromagnetic induction heating, improve the temperature of the charge, reduce smelting energy consumption.

Electromagnetic heating in the practical application of iron ore has the advantages of rapid heating, efficient utilization of energy, precise control of heating temperature and so on. It can improve the processing efficiency of iron ore, reduce energy consumption, and is environmentally friendly. Therefore, in the mining and metallurgical industries, electromagnetic heating is widely used in the pretreatment and smelting process of iron ore to achieve higher production efficiency and quality control.
