Description
Ladle Refining Furnaces
A ladle refining furnace is used to refine the molten steel melted in a primary smelting furnace (converter, medium frequency furnace, medium frequency induction furnace, electric arc furnace, etc.), and has the functions of adjusting molten steel temperature and process buffer. It is known as the soul of the best production line (primary smelting furnace + LF + continuous casting). Refined steel types include ball bearing steel, alloy structural steel, tool steel, spring steel, carbon structural steel, etc.

Features
1. The operation is simple and intuitive, and the man-machine dialogue effect is very friendly;
2. The electrode lifting speed regulation range is large, which can quickly lift the electrode;
3. The non-sensitive area is continuously adjustable, and the size of the nonsensitive area can be adjusted at any time according to the furnace condition; The system has a short response time and high adjustment accuracy;
4. Fast arc stabilization, accurate current regulation, and small power grid impact;
5. Due to the use of PLC photoelectric isolation control, it has a strong anti-electromagnetic interference ability. In addition, the system adopts a modular design, which has stable and reliable operation and an extremely low failure rate;
6. Using PLC programming, more complex calculations can be carried out, such as three-phase power, current and voltage balance control, and the program modification is very convenient;
7. Simple and clear operation and convenient maintenance;
8. Low investment, quick effect and low energy consumption.
9. Strong craftsmanship and advanced software programming.
