What inspections must be done before using the metal melting furnace?

In order for the metal melting furnace to be better used when working, it is necessary to:

(1) Use a temperature measuring gun to observe the temperature of the thyristor and the RC protection resistor and the working temperature of the voltage equalizing resistor. The temperature measurement time is divided into three stages: the first temperature measurement is when the metal melting furnace is running the first molten steel, about one-third of the power is turned on, and the temperature is measured about 5 to 10 minutes later. The second time was about when the molten steel was almost full. Then for the third time, the temperature was measured at the end of the smelting, which is today’s last furnace with full power. Of course, all the above 3 temperature measurements need to be recorded in order to find and solve problems in time.

(2) Check whether the cable screws are loose or not every day.

(3) It is necessary to confirm that the power supply water pump and the furnace water pump are turned on every day before starting the machine. The water pressure is 1.5 to 1.7 kg in the power cabinet and 1.5 to 2 kg in the furnace.

(4) Keep the furnace body clean and free of iron filings and metal objects near the water cables.
