Function
1. Electric arc heats up and temperature rises under constant
pressure, measure temperature and take samples, finally temperature
control is accurate so as to optimize casting temperature.
2. Synthetic slag goes through refining, desulfuration,
deoxidation, degasification and removal of inclusions
3. Bottom blowing argon siring. make liquid steel temperature
uniform and make components uniform and pure.
4. Alloy fine adjustment makes component controlled accurately. The
finally required chemical composition could be achieved with high
efficiency through ferroalloy element or aluminum or wire feeding.
5. Being equipped with wire feeder makes liquid steel realize
desulfuration and deoxygenation, changes inclusion pattern and
distribution and accurately controls alloy elements. And it has
high alloy yield, low temperature drop and low environmental
pollution.
6. As buffering equipments between primary melting furnace and
continuous casting machine, ensure matching production of primary
meting furnace and continuous casting, realize sequence casting.
Characteristics
1. Adopting the water cooled furnace roof equipped with dedusting
interface of which the size of smoke outlet is adjustable to keep
the tiny barotropic atmosphere and reducing atmosphere inside the
furnace.
2. Using the cooper-steel composited conductive arm, reducing
electrode pitch circle diameter and prolonging lining service life.
3. Equipped with automatic or manual temperature measurement and
sampling device to measure the liquid steel temperature accurately.
4. Large current system adopts large-section water cooled cable,
compensators and copper-steel composite conducive arm, thus reduce
major loop impedance.
5. Using alloy and slag automatic charging device to accurately
measure the charging volume.
6. Equipped with PLC control system and smelting model.
