    Electric furnace principle(原理)

    Which furnace is used for forging?

    As the name suggests, the forging heating furnace is used for heating before forging, heating before hot stamping, heating before rolling, and heating before round steel quenching and tempering. The heating temperature is generally lower than 1250 degrees, and the heating furnace shape is different, but in the end To achieve the purpose of heating. So, what is the classification of forging heating furnaces? Summarize the following classification methods for your reference.

    1. Classification of forging heating furnaces:

    According to the type of energy, forging heating furnaces can be divided into two categories: fuel furnaces (flame furnaces) and electric heating furnaces.

    1. Fuel furnaces (flame furnaces) for forging heating furnaces include: coal furnaces, coke furnaces, heavy oil furnaces, diesel furnaces, artificial gas furnaces and natural gas furnaces.

    2. Electric heating furnaces for forging heating furnaces include resistance furnaces and induction heating furnaces .

    2. Application of forging heating furnace:

    1. Heating before forging: Mainly used in the heating process of round steel, bar stock, aluminum rod, copper rod, stainless steel rod, steel plate, steel pipe, gear, ring gear, semi-shaft connecting rod, bearing and other products before forging;  

    2. On-line heating: refers to steel ball rolling heating, tube billet reaming heating, round steel quenching and tempering production line , hot coil spring billet heating, pipeline anti-corrosion spraying, bar blue brittle blanking, steel pipe quenching and tempering production lineetc. Craft

    3. Local heating: Local heating is the heating of the middle or end parts of the round steel. For example, the production and heating processes of drill pipe head heating, drum thermal assembly, steel pipe bending and so on.

    4. Rolling heating: used for heating before rolling of shafts and rods, and often used for heating and rolling of motor shafts.

    3. Heating principle of induction heating furnace for forging :

    The induction heating furnace for forging is currently very commonly used in the heating industry. The induction heating furnace is a power supply device that converts the power frequency 50HZ alternating current into an intermediate frequency ( above 100HZ to 10K HZ ). It can convert the three-phase power frequency alternating current into direct current after rectification, and then turn the direct current into an adjustable intermediate frequency current, supply the intermediate frequency alternating current flowing through the capacitor and the induction coil, and generate high-density magnetic lines of force in the induction coil. And cut the metal material contained in the induction coil, which produces a large eddy current in the metal material. This eddy current flows in a metal body with electrical resistance to generate heat to heat the metal.

    The heating method of induction heating furnace for forging is non-contact heating, with high heating efficiency, fast heating speed, high production efficiency, uniform heating, small core surface temperature difference, less oxidation and decarburization, material saving, good working environment and low production cost. Suitable for mass die forging production and precision forging.
