LF furnace, full name is Ladle Refining Furnace, is a kind of equipment which has the function of heating and refining. It is an important metallurgical equipment used to refine molten steel in primary smelting furnace (electric arc furnace, open hearth furnace and converter), adjust temperature of molten steel, buffer process and meet requirements of continuous casting and continuous rolling. Ladle furnace is one of the main equipments in secondary refining.
Features:
LF furnace has the features such as atmospheric pressure arc heating, vacuum degassing, argon stirring, blowing oxygen feed wire, pressure or vacuum feeding, temperature measurement, sampling, TV camera and frequency observation functions. And the furnace is mainly consists of the following parts:
1. Ladle and ladle car;
2. Heating device (electrode control modes: manual control or automatic control using energy-saving bus bar and conduction arm).
3. Vacuum and detection system.
4. Hydraulic and control valve system.
5. Argon , oxygen, compressed air and water cooling systems.
6. Electrical control system (with PLC control and CRT image Impersonation shown).
7. High Voltage Electric Systems.
8. Large current line.
