The main functions of electricity

In order to ensure the reliability and safety of primary equipment operation, it is necessary to have many auxiliary electrical equipment to serve it. The combination of several electrical components that can achieve a certain control function is called a control circuit or secondary circuit. These devices should have the following functions:

Electrical system composition

The basic return route of commonly used control circuits consists of the following parts.(1) Power supply circuit. There are various power sources for the power supply circuit, including AC380V and 220V.(2) Protection circuit. There are various working power sources for the protection (auxiliary) circuit, including single-phase 220, 36V or DC 220, 24V, etc., which provide various protections for electrical equipment and circuits such as short circuit, overload, and voltage loss. They are composed of protective components such as fuses, thermal relays, voltage loss coils, rectifier components, and voltage stabilizing components.

Matters needing attention when using intermediate frequency furnace

1. Before starting the furnace, check whether the electrical equipment, water cooling system, copper tube of the sensor are intact, otherwise it is forbidden to open the furnace.2. Furnace melting loss should be repaired in time if it exceeds regulations. Smelting is strictly prohibited in crucibles with excessive melting.3. The pouring site and the pit in front of the furnace should be free of obstacles and water, so as to prevent molten steel from exploding on the ground.

Method for reducing electrode loss in electric furnace of intermediate frequency furnace

The main reasons for electrode wear in electric furnaces such as steel and intermediate frequency furnaces are: It is divided into two aspects: first, chemical loss caused by oxidation during the smelting process, and second, physical loss caused by broken electrodes.

Why is the energy saving and environmental protection of the intermediate frequency furnace?

In the smelting industry, if it is said which type of smelting equipment is most recommended, many people in the industry will recommend intermediate frequency furnaces. The intermediate frequency furnace has many advantages over other melting furnaces, but what people value most is the performance of the intermediate frequency furnace in energy saving and environmental protection.
