Induction melting furnace electrical maintenance and precautions for use

(1) The overload capacity of the thyristor components of the induction melting furnace is low, so overloading is not allowed.

(2) During the smelting process of the induction melting furnace, no wire contact is allowed in the machine or the induction coil of the furnace, which will cause the equipment to be short-circuited and damaged.

(3) When replacing the thyristor components of each bridge arm in the equipment, pay attention to pairing and use. Pay special attention to the consistency of the turn-off time and the consistency of dynamic voltage equalization of the inverter two-series thyristor components. The turn-off time of the selected thyristor components is 40jxs the following.

(4) When checking the thyristor circuit, it is not allowed to use a shaker, and a multimeter must be used.

(5) During the test run, the induction coil of the furnace must be put in and the circuit cannot be opened.
