LRF ladle refining furnace is the most widely used refining equipment outside the furnace at present. The LRF furnace is used to refine the molten steel melted in the primary furnace, and can adjust the molten steel temperature and buffer the process.

The ladle furnace refining equipment has many advantages, such as reasonable equipment structure, reliable operation, low cost, many refined steel types, high quality and convenient operation.

FUNCTIONS

CONDITIONS AND FUNCTIONS OF LRF IN STEEL MAKING

 The LF furnace specification is from 8t to 300t, and has the following conditions and functions:

The working conditions in the LRF steel making furnace are reducing atmosphere and micro positive pressure;    

The electrode adjustment mode of the industrial furnace ladle is three arm three-phase electrode adjustment;    

The thermodynamic condition of the ladle heating furnace is graphite electrode arc heating;

The dynamic condition is argon stirring at the bottom of the ladle;

Add a certain amount of scrap crushing material into the ladle, heat it up with electric arc, measure the temperature and take samples to make the temperature control accurate, so as to optimize the pouring temperature;

Bottom blowing argon stirring to make the temperature of molten steel uniform, the composition uniform and the molten steel pure;

Slagging to remove sulfur and inclusions in molten steel;

Adjust the alloy composition and use the alloy feeding system to make the composition control accurate and the molten steel meet the final required chemical composition;

Wire feeding treatment: directly feed various wires into molten steel with a wire feeder, which can significantly improve the yield of alloy;

Smoke exhaust and dust removal. Equipped with a smoke exhaust and dust removal system, it can effectively control the smoke discharge and make the smoke emission meet the requirements of environmental protection;

As the ladle refining equipment outside the ladle arc furnace between the primary refining furnace and the continuous caster, it plays a buffer and regulating role in the production process of the whole workshop to ensure that molten steel with qualified temperature and composition is provided to the continuous caster.
