Usage of ladle furnace:
LF ladle refining furnace is used to refine molten steel of the primary 

smelting furnace (electric arc furnace, converter). It can create a micro positive 

pressure reduction system and can realize the operation of submerged arc 

heating, argon stirring, white slag refining, fine adjustment of alloy 

constituent, wire feeding, etc. Its function on molten steel is degassing, 

desulfuration, purifying and controlling temperature and constituent accurately. 

At the same time, it has the function of buffering and adjustment on primary 

smelting and continuous part.

Form of device structure:
Common form of LF ladle refining furnace includes rackle-type and 

independent frame.
According to conductive cross arm: single arm, three-arm, rotary cross arm 

(double station)
According to method of ladle delivery: ladle cart type, large rotary table type.

Constitution of ladle furnace:
Furnace transformer, short net, electrode lifting device, furnace lid, furnace 

lid lifting device, heating rackle, (independent frame), electrode rotary device, 

ladle, ladle cart(ladle turret),argon automatic control system, water cooling 

system ,compressed air system, hydraulic system, sampling device of 

temperature measurement, charging system, high voltage supply system, low 

voltage electrical control system, automatic system, wire feeder, etc.
