LF Ladle Refining Furnace LF-75t for Sale
The LF ladle refining furnace is used for molten steel refining. The structure type is divided into the heating bridge, fourth column, cross arm rotation and large package rotary table for users to choose.
The LF ladle refining furnace equipment consists of the ladle, ladle car and streamer, furnace cover, electrode lifting mechanism, short net, water cooling system, hydraulic system, argon system, electric furnace transformer, high voltage cabinet, low voltage electrical and automatic control system, etc. Tonnage ranges from 10 tons to 300 tons.
Features
1. The arc is heated and heated under normal pressure, the temperature is sampled, and the final temperature is precisely controlled to optimize the pouring temperature;
2. Synthetic slag refining, desulfurization, deoxidation, degassing, removal of inclusions;
3. Blowing argon gas at the bottom to make the temperature of the molten steel uniform, uniform and pure;
4. The alloy fine-tuning makes the composition control accurate, and the final chemical composition can be efficiently achieved by ferroalloy elements or aluminum or wire feeding;
5. With the feeding machine, the molten steel is desulfurized and deoxidized, the shape distribution of the inclusions is changed and the alloying elements are accurately controlled. At the same time, the alloy has a high yield, the molten steel temperature is small, and the environmental pollution is small;
6. As for buffering equipment between the primary refining furnace and the continuous casting machine, it is ensured that the primary refining furnace and continuous casting are matched to produce and the multi-furnace continuous casting is realized.
Characteristics
1. The water-cooled furnace cover is equipped with a dust-removing interface that can adjust the length of the extended exit so that the furnace is always operated under a micro-positive pressure reducing atmosphere;
2. The copper-steel composite conductive cross arm is used to reduce the diameter of the electrode distribution circle and improve the service life of the lining;
3. Equipped with automatic or manual temperature measurement sampling device to accurately measure the temperature of molten steel;
4. The large current system adopts large-section water-cooled cable, compensator and copper-steel composite conductive cross arm to reduce the main circuit impedance;
5. Using alloy and slag automatic feeding device, accurately metering the alloy and slag in the bag;
6. Equipped with PLC control system and smelting model.
