Bar Heating Induction Furnace

The induction furnace for bar heating is well understood from the literal meaning, that is, the medium frequency furnace for heating bar. However, the connotation is not simple, and the bar heating process is relatively complex. Why do we think the bar heating induction furnace is complex? Let's give you a detailed introduction.

1. Differences between bar heating induction furnace and other heating furnaces

1) The heating principle is different

Most of the previous bar heating furnaces used coal, gas, oil, and resistance heating. The heating principle is radiation heating, that is, the furnace is heated to a certain temperature and transmitted to the heating bar through heat radiation, so that the bar temperature can reach the process heating temperature; The medium frequency furnace for bar heating adopts the principle of electromagnetic induction heating, which cuts the metal through the magnetic line of force, forms a vortex in the bar, the current flows, and the bar heats itself, so as to achieve the purpose of heating the bar. In other words, in the past, the heating furnace heated the bar through heat conduction, but now the heating furnace of Haishan electric furnace generates eddy current through the magnetic line of force, making the bar heat itself.

2) The heating speed is different

The previous bar heating furnace had to raise the furnace temperature to the process temperature for a long time; Now, the bar heating of electric furnace, the instantaneous electromagnetic induction of the medium frequency furnace can make the bar reach the temperature required by the heating process, which does not need the preliminary preparation for furnace temperature rise and reduces the labor intensity.

3) Meet the environmental protection requirements

The previous heating furnace will produce a large amount of smoke and dust in the combustion of coal, oil and gas, while the bar heating induction furnace makes the bar heat itself and will not produce smoke and dust, which meets the environmental protection requirements. It belongs to the heating industry and advocates the development of water temperature heating equipment.

4) The utilization rate of bar material is different

In the past, the heating time of heating furnace was long, the oxidation burning loss was large, and the utilization rate of bar oxide scale was reduced; Nowadays, the medium frequency furnace for bar heating of Haishan electric furnace has fast heating speed, reduced oxidation burning loss, greatly reduced relative oxide scale and greatly improved bar utilization.

2. Basic parameters of induction furnace for bar heating

1) The induction furnace for bar heating is expressed by heating power and heating frequency: 

the heating power is 100kW -- 20000KW; The heating frequency is different according to the outer diameter of the bar, and the frequency range is 50Hz --- 8000Hz:

2) The medium frequency furnace for bar heating is mainly composed of the thyristor control circuit, and the model is expressed as: 

KGPS power / frequency; 

The heating furnace head is expressed as GTR - bar diameter; 

KGPS is used together with GTR and cannot be used alone.

3) The material of bar heating induction furnace heating bar is: alloy steel, alloy aluminum, stainless steel, alloy copper, titanium alloy and other metal materials

4) The heating temperature of medium frequency furnace for bar heating can be heated at different temperatures according to the heating process requirements. Generally speaking, the forging heating temperature is 1200 ℃; The quenching heating temperature of bar material is between 700 ℃ - 1000 ℃; The tempering heating temperature of bar material is between 450 ℃ - 600 ℃; Warm forging temperature is between 800 ℃ - 9000 ℃;

3. Auxiliary equipment of induction furnace for bar heating

Bar heating medium frequency furnace is commonly used in bar forging heating industry and bar quenching and tempering heating industry. Supporting auxiliary equipment can realize the automation of heating production line. These auxiliary equipment include automatic feeder, roller conveyor, cylinder pushing, temperature detection device, PLC control system, discharge system, hsbl cooling system, power supply device, etc, The main purpose is to realize the intellectualization of bar heating medium frequency furnace production line, and it is also the main force of intelligent factory construction at present.

To sum up, the bar heating medium induction furnace has obvious heating characteristics, is deeply loved by people in the heating industry, and is also the mainstream equipment in the bar heating industry at present.
