Печь для переработки ковша VD/VOD 50 тонн 100 150

VD/VOD ladle refining furnace 50 Ton 100 Ton 150 Ton Ladle Refining Furnace

Aluminum Shell/Steel Shell/Copper

1. Arc heating at normal pressure, temperature measurement and sampling, and final temperature precise control can optimize the pouring temperature;
2. Refining, desulfurization, deoxidation, degassing and inclusion removal of synthetic slag;
3. Bottom blowing argon stirring makes the temperature of molten steel uniform, the composition uniform and pure;
4. Alloy fine-tuning makes the composition control accurate, and the final required chemical composition can be efficiently achieved by ferroalloy elements or aluminum or wire feeding.
5. With wire feeding machine, desulfurization and deoxidation of molten steel can be achieved, morphological distribution of inclusions can be changed, and alloy elements can be accurately controlled. At the same time, the alloy yield is high, the temperature of molten steel is low, and the environmental pollution is small.
6. As the buffer equipment between primary smelting furnace and continuous casting machine, it ensures the matching production of primary smelting furnace and continuous casting, and realizes multi-furnace continuous casting.

1. The water-cooled furnace cover is equipped with a dust removal interface which can adjust the size of the delayed outlet, so that the furnace can always operate in 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 furnace lining.
3. It is equipped with automatic or manual temperature measuring and sampling device to accurately measure molten steel temperature.
4. Large cross-section water-cooled cable, compensator and copper-steel composite conductive cross-arm are used in large current system to reduce the main circuit impedance.
5. The automatic feeding device of alloy and slag is used to accurately measure the alloy and slag added into the package.
6. It is equipped with PLC control system and smelting model.
