News on May 26: according to the preliminary data released by the international copper research organization (ICSG) in the may express

First, check the power switch and control switch to see if they are closed; If the control switch is turned on and gives an alarm, the following processing shall be carried out according to the alarm information

Fault phenomenon: the discharge inductance is heated or even burnt out in the boost load

Silicon steel sheet for electrical purposes is commonly known as silicon steel sheet or silicon steel sheet

During the smelting process of medium frequency furnace, a large amount of smoke and dust will be emitted into the air, seriously polluting the environment and affecting the health of workers.

During the design of intermediate frequency power supply, the following principles can be followed to select the appropriate inverter thyristor according to the actual application

The medium frequency power supply below 1000kW for the medium frequency furnace generally adopts three-phase five wire 380V, 50Hz industrial power

At present, the main smelting furnaces are vacuum induction smelting furnace, electric arc smelting furnace and electroslag remelting.

Common smelting methods and heating principles

When designing the inductor, it is necessary to know the material, size, temperature and productivity of the workpiece in advance

Fault phenomenon: the equipment can be started, but the voltage rise is not high, which is easy to produce overcurrent or overvoltage fault

Fault phenomenon: the equipment can be started, but the voltage rise is not high. The reactor is very loud and dull. When the voltage rises, it is very unstable and trembling.
