Lf Ladle Refining Furnace(Secondary Steelmaking)

Lf-typed ladle refining furnace is used for refining molten steel from primary melting furnace (eaf or convertor), can create a slightly positive pressure reducing atmosphere, apply such means as submerged arc heating, argon stirring, white slag refining, alloy composition trimming, wire feeding under the atmosphere to conduct degassing, desulfuration, decontamination for hot metal, and accurately control the ingredients and temperature of molten steel. The equipment also has an effect of buffering and adjusting continuous casting links. It consists of: Transformer for electric furnace, network, electrode lifting and lowering device, ladle lid and ladle lid lifting and lowering device, heating bridge frame, steel ladle, ladle carrier, wire feeder, argon regulating system, water cooling system, compressed air system, hydraulic system, temperature measurement and sampling system, automatic charging system, high-voltage power supply system, low-voltage electrical control system and automation system, etc. Type of lf furnace : Bridge type or the type with independent rack mount and furnace cover; single arm or three-arm; ladle revolving platform or furnace lid rotary type, etc.

LF type ladle refining furnace   Usage : 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: 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.

Ladle refining furnace is used to refine the molten steel from primary melting furnace (electric arc furnace, induction furnace, converter and etc.), meanwhile have the function of adjusting molten steel temperature, and be a buffer of the whole process. It is described to be soul of the best production line (primary melting furnace + lf+ ccm). It is widely used in refining all kinds of steel grade, such as ball bearing steel, alloy structural steel, tool steel, spring steel, carbon steel and etc. Capacity 20-150t, transformer rated capacity 3150-20000kva
