Quickly and safely remove solidified slag, adhered slag and cold steel on the doors of Electric Arc Furnace (EAF) and Eccentric Bottom Tapping Furnace (EBT), so as to ensure continuous, stable and safe smelting.
Molten steel splashes during melting and forms slag buildup up to 600 mm thick on the furnace door, which will block lance insertion, temperature measurement, sampling and tapping.
The machine completes slag removal in 2–3 minutes, compared with 15–20 minutes by manual work, effectively shortening the smelting cycle.
It replaces manual work near the high-temperature zone of 1700℃, preventing injuries caused by thermal radiation, splashing materials and slag collapse, and nearly eliminating on-site accidents.
Equipped with remote control, it keeps operators away from hazardous areas.
It avoids damage to furnace door frames and seals caused by slag extrusion, extending the service life of furnace lining by more than 30%.
On-site operators are reduced from 3–4 persons to 1. Power consumption per furnace is cut by 8%–12%, bringing substantial annual electricity savings.
Timely slag removal prevents slag-steel mixing, reduces inclusions and raises the qualification rate of steel composition.
Push unmelted scrap steel back into the furnace to increase metal yield.
Keep the furnace door in stable condition to facilitate subsequent tapping and slag treatment.
Mini-mill Steel Plants: Slag removal for doors of 10–150 tonne EAF and EBT furnaces.
Special Steel & Alloy Plants: Applied to smelting of stainless steel, bearing steel and other special steels where thick slag easily accumulates on furnace doors.
Foundries: Used for large cast steel production with EAF furnaces. Frequent slag removal ensures smooth pouring operation.
