Crucible of medium frequency furnace and refractory mastic lining

affected by furnace lining refractory, furnace drying process and service process, which are introduced below.

On May 4, the person in charge of Luoyang shennai and his delegation visited the customer enterprise MCC-SFRE Heavy Industry Equipment Co., Ltd. in Fuping, Shaanxi Province, discussed the technical transformation of shennai electric furnace with relevant operation engineers during the plant equipment maintenance period, and put forward the maintenance and rectification plan.

According to different magnetism, all metals and alloys can be divided into two categories:

Fault phenomenon: the equipment operates normally and the DC current indication is high. If the current is set at the rated value, the voltage is too low, and the indicated value of the power meter is inconsistent with the product of DC voltage and DC current, which was consistent before.

Fault phenomenon: when the equipment is running, the DC voltage and intermediate frequency voltage have reached the rated value, but the DC current is small and the power is low.

Fault phenomenon: when the equipment is running, the DC current has reached the rated value, but the DC voltage and intermediate frequency voltage are low. Observe the intermediate frequency voltage waveform with an oscilloscope. The waveform is normal and the front angle of the inverter is also normal.

Fault phenomenon: there is no response when the equipment is started. After observation, the phase loss indicator on the control circuit board is on.

When current flows through a conductor, a magnetic field is formed around the conductor. When the conductor flows through alternating current, that is, the value and direction of current change periodically, the magnetic field also changes with it.

Harmonics in the power system come from electrical equipment, that is, from power generation equipment and electrical equipment. 

As an advanced heating method, induction heating has the following advantages over traditional heating methods

Heat in a resistance furnace. The metal is installed into the furnace, the current flows through the heating element to generate heat, and the temperature of the furnace is increased by radiation and convection, so as to heat the metal.
