It's an crucial metallurgical equipment for producing the high quality carbon steel, bearing steel, tool steel, stainless steel. etc. and meet the needs of continuous casting and continuous ligation.

Device features:

This device have functions of electric arc heating, argon stirring, wire feeding, measuring temperature and sampling, alloying, etc. Ladle refining furnace users can make choicesby following the steel grade and smelting technology.

Device components:

Ladle, ladle car and towline equipment, heating framework of bridge and guide roller equipment, cover of heater and lifting appliance. electrode positioning mechanism, feeding system. High current system, themometric sampling unit, argon forming system, water-cooling and compressed-air system, hydraulic pressure system, high-pressure system, furnace transformer, low pressure control system, automation control system.

Component parts:

•Ladle and carrier

• Heating device

•Electrode control types: Manual or Microcomputer control

•Hydraulic and valve control system
