Square steel induction heating furnace

Square steel induction heating furnace is an induction heating furnace designed for forging after heating square steel, mainly used in the heating process before forging. Because it is specially designed and manufactured for square steel heating, its power supply parameters, coil design, and equipment structure still have their own characteristics, which are very different from other induction heating furnaces. So, what are the specific characteristics of the square steel forging induction heating furnace? What is the difference with other induction heating furnaces? Below, I will give you a detailed introduction.

1. Heating purpose of square steel forging induction heating furnace:

Square steel forging induction heating furnace is mainly used for heating alloy steel, alloy aluminum, alloy copper, stainless steel, titanium alloy and other alloy square steel, square steel and long shaft workpieces. The heating temperature of alloy steel: 1200 degrees; alloy aluminum: 480 degrees; alloy copper: 1100 degrees; stainless steel 1250 degrees.

2. Heating coil of square steel forging induction heating furnace:

The square steel forging induction heating furnace is mainly used for heating square steel, and its coil structure is different from the smelting furnace used by the induction heating furnace for smelting.

1. First of all, the square steel forging induction heating furnace heating coil is called an inductor or a diathermy furnace induction coil. It is composed of many turns of coils connected in parallel or in series. The number of turns is related to the heating power, material, heating temperature, and copper tube. Factors such as specifications and production efficiency are related. There are through-type heating coils to distinguish between end and local heating coils, which are used for the overall heat transmission of square steel or the end and local heat transmission of square steel.

2. The heating temperature of the heating coil of the square steel forging induction heating furnace is different from other intermediate frequency heating coils. The heating coil of the square steel forging induction heating furnace is only used for heating before forging or for quenching and tempering of square steel, and heating according to square steel forging Process or tempering heating process heating, generally does not exceed 1200 degrees; while the melting heating temperature of the induction heating furnace is as high as 1650 degrees, the main purpose is to design for metal melting. Due to the different heating temperature of the induction heating furnace, the selected rectangular copper tube specifications are different. Especially the temperature resistance value of the lining material is very different.

3. Auxiliary equipment of square steel forging induction heating furnace:

The square steel forging induction heating furnace is designed for the square steel forging or quenching and tempering production line, and it mainly includes the feeding platform, the conveying mechanism, the pressure roller device, the temperature measuring mechanism and the PLC control console, etc.; and the induction heating furnace is used for melting , There is only a loading car and temperature measurement and dumping mechanism, not as complicated as a square steel forging induction heating furnace. The temperature measurement method is also different. The square steel forging induction heating furnace adopts infrared temperature measurement, and the intermediate frequency melting furnace adopts the thermocouple type temperature measuring gun to measure the temperature.

Fourth, the characteristics of square steel forging induction heating furnace:

1. Compared with coal-fired, gas-fired, oil-fired and resistance furnace heating, the square steel forging induction heating furnace has the characteristics of fast heating. The ready-to-use function requirements reduce the preparation time for the square steel heating and reduce the labor intensity of the operators.

2. Compared with the traditional heating of coal-fired, gas-fired, oil-fired and resistance furnace heating, the square steel forging induction heating furnace has its own unique characteristics of uniform heating. The traditional square steel heating is generally box-type and radiant heating. That is, after heating the furnace to the process temperature, the heat radiation is conducted to the square steel, so that the square steel reaches the forging heating temperature; the square steel forging induction heating furnace uses the principle of electromagnetic induction, electromagnetic cutting of the metal causes the induction current inside the square steel metal, and the current is in The internal flow of the square steel generates heat so that the square steel itself heats up and reaches the forging or quenching and tempering temperature. It has the characteristics of fast speed and uniform temperature.

3. The square steel forging induction heating furnace is energy-saving and environmentally friendly, electromagnetic induction does not produce smoke and dust, the working site environment is good, the degree of automation is high, and the amount of labor is small, which meets the current smart factory and environmental protection requirements.

4. Due to the fast heating speed of the square steel forging induction heating furnace, the surface oxidation of the square steel is reduced during the heating process, and the oxide scale is greatly reduced, which can be reduced to less than 0.25%, which greatly reduces the burning problem during the forging process and improves the square steel. Utilization rate of steel.

In summary, the square steel forging induction heating furnace has its own unique advantages, and it is also the preferred heating equipment for square steel forging and modulation heating.
