Cost effective steel bar heating furnace ‘detailed introduction’

Steel bar heating furnace is a mature induction heating equipment, especially before die forging, steel bar heating furnace is indispensable. The medium frequency heating furnace is the main heating furnace for die forging. Fast heating speed, convenient operation, energy conservation and environmental protection have won a lot of reputation for the medium frequency heating furnace.

1. Background of steel bar heating furnace:

The traditional heating method of steel bar heating furnace is flame heating, which heats steel bars by burning heavy oil, natural gas and other media. It has the disadvantages of poor heating environment, long heating time and high cost of flue gas desulfurization. With the progress of science and technology and the maturity of medium frequency components, the steel bar heating furnace has gradually transitioned to the era of medium frequency heating furnace. Flame heating is only used in free forging heating, while the heating of steel bars in die forging has been dominated by medium frequency heating furnace. Medium frequency heating furnace for steel bar is an indispensable induction heating equipment for heating before die forging.

2. Composition of steel bar heating furnace:

The steel bar medium frequency heating furnace is composed of medium frequency power supply, inductor, controller, inductor furnace frame, cooling system, cylinder pushing system, automatic feeding system, temperature measurement and sorting system, conveying system, discharging system and control system.

3. Characteristics of steel bar heating furnace:

(1) The heating beat can be designed according to the productivity. The heating speed is designed according to the heating power, heating temperature and the weight of the heated workpiece. The heating speed can be up to 3 seconds and can be adjusted arbitrarily.

(2) An electromagnetic induction heating equipment that can work continuously for 24 hours and adopts the principle of electromagnetic induction to quickly induce a large eddy current inside the metal material in the alternating magnetic field, so as to heat the metal material until melting. It can also penetrate the non-metallic material and quickly heat the metal material locally or completely.

(3) There are few problems. If there are problems, 90% of them are caused by insufficient water pressure or water flow. It is recommended to use the internal circulating water system, that is, the closed cooling tower, to cool the medium frequency heating furnace, which can greatly improve the stability of power supply, be economical and cost-effective.

(4) The heating range of medium frequency heating furnace is very wide, and there can be various forms of heating methods, which can heat all kinds of workpieces (replace the removable induction ring according to the shape of workpieces), such as end heating, overall heating, steel plate heating, etc

(5) It belongs to direct heating, because there is no heat loss of radiation conduction heating due to the internal heating of metal, so it consumes less power, less heat loss, less specific friction, and 20% – 30% less energy consumption than other similar products, reducing the production cost.

(6) It is safe and reliable, with alarm indications such as overvoltage, overcurrent, overheating and water shortage, and automatic control and protection. No high voltage, safe operation of workers.

At present, the steel bar induction heating furnace is the steel bar medium frequency heating furnace. From the above, we can see the specific content of the steel bar heating furnace. Hebei FOREVER electromechanical Co., Ltd. is a professional manufacturer of induction heating equipment, induction heat treatment equipment and quenching and tempering heat treatment furnace. Suitable induction heating equipment is customized according to the actual process needs of users.
