LRF LADLE REFINING FURNACE

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.
