LF Ladle Refining Furnace

The LF ladle refining furnace can be used for refining molten steel in primary furnaces (electric arc furnaces, converters). It is important metallurgical equipment for continuous casting and rolling. It has the functions of atmospheric arc heating, argon blowing and stirring, alloy feeding, temperature measurement, sampling and so on. It is excellent equipment for refining outside the furnace.

 

Equipment Composition

1. Ladle and ladle car;

2. Heating device (electrode control mode: manual control or microcomputer automatic control. Energy-saving short net and conductive cross arm are used);

3. Vacuum and detection system;

4. Hydraulic and control valve system;

5. Argon, oxygen, compressed air and cooling water systems;

6. Electrical control system (using PLC control and CRT image analog display);

7. High voltage power system;

8. High current circuit.

The combination of LF ladle refining furnace and EBT electric furnace can achieve short processes, improve steel quality, reduce production costs, and expand smelting varieties.
