Electroslag furnace

Electroslag furnace

Capacity:100kg-1.5t 2ton-20t,30-50ton

The electroslag remelting furnace is a device for remelting metal by using the thermal energy generated by current through high resistance slag. Electroslag remelting is generally carried out under atmospheric pressure, and vacuum units can also be configured for vacuum refining as required.

Chinese name electroslag refining furnace Foreign name electroslag refining furnace Advantages High purity, low sulfur content, less non-metallic inclusions Composition Furnace body, power supply system, control system, etc. Principle The resistance heat of the slag is used as the heat source

The structure overview

The furnace consists of vacuum melting chamber, column-oriented coupling body, vacuum system, pneumatic system, water cooling system, electrical system and other components.

1. Vacuum melting chamber: the furnace, the electrode rod and lifting devices, molds and other components.

2. Column guide coupling body: from the vacuum transition chamber, column guide body, drive and other components.

3. Vacuum system: mechanical vacuum pumps, roots pumps and valves, piping and other components. According to the needs of smelting process can be used separately or alone.

4. Pneumatic system [see attached Figure 6]: By the air compressor, constant pressure valve, oil-water separator, oil mist, with gas pipe, valve and other components. To ensure the movement of the pneumatic components.

5 water cooling system [see Figure 5]: water cooling system by the points, water return pipes and various auxiliary devices such as: water temperature gauge, pressure gauge, ball valve and other components. For cooling power, electrodes, furnaces and so on. It can supply water at the same time or separately, and it can provide alarm protection functions such as total water pressure alarm, crucible water pressure shortage and crucible water temperature too high.

6. Power and electronic control system: from the vacuum system power supply, power lifting rod, stable arc power supply and smelting main power, pneumatic lift control and other parts.
