Method for melting molten steel in induction melting furnace
Method for melting molten steel in induction melting furnace
Scrap steel must be added sparingly, added frequently, and mashed frequently to prevent “building sheds”. If it is not found in time after the “scaffolding”, the temperature of the molten steel at the lower part will be too high and it will burn through the furnace lining.
When the induction melting furnace is remelted or the steel (iron) water is kept warm, it is necessary to observe that the upper layer cannot be crusted. Once the crust is found, remove the crust in time or tilt the furnace body at an angle so that the molten steel in the lower layer will melt the crust, and there will be a vent hole to avoid explosion.
When the excess molten steel is returned to the furnace, there should be no cold material in the furnace, and the molten steel should be poured after reducing the power.
When tapping steel, tapping is generally performed.
When the tilting furnace body injects the molten steel into the ladle, the power should be cut off first, and then the machine should be operated to pour slowly. The ladle must be baked and dried. Moisture and accumulation of water are strictly prohibited in the pit in front of the furnace.
Once the tilting furnace cannot be stopped (out of control), cut off the power supply of the tilting reducer in time (or turn the furnace selection switch to the middle position) to stop the tilting furnace. For hydraulic tilting furnace, press the emergency stop button.
The reasons for this are generally:
a. The contacts of the contactor are burnt to death;
b. The button of the button box cannot be played when pressed;
c. The cable sheath of the button box is damaged causing a short circuit.
