Find high quality ladle furnace with competitive price here. Please rest assured to buy ladle furnace with Xi'an Huachang Metallurgical Technology Co.,Ltd

Usage:

Ladle refining furnace belongs to the secondary refining equipment, which typically to be used follows the primary melting furnace. Its main function is to remove sulfur, impurity from molten steel and adjust chemical components, thereby, improve quality of molten steel. LF is mainly used in high-quality carbon steel, stainless steel, manganese steel and other metal smelting.

Features: 

1. LF is not available for oxidizing period smelting, because the whole process of refining atmosphere is reduction reaction.

2. LF refining furnace usually carried out in the ladle, with blowing argon stirring, can achieve a better effect of removing sulfur, impurities, as well as adjusting the composition of the alloy and accurately control the temperature of molten steel.

3. If the primary smelting equipment is induction furnace, then follows LF, which can improve the quality of molten steel, completely finish adjusting the alloy composition. 

4. If the primary smelting equipment is EAF, then follows LF, which can replace the arc furnace to finish the refining process of molten steel, at the same time, arc furnace only as a melting furnace. This method can significantly improve the smelting efficiency.

5.Production Capacity: 8t—200t

Strengths of HC Ladle Refining Furnace

1. Low power consumption   

2. Optimized structure, Low failure rate, limited investment

   Three electrode clamping device installed in the cross arm, the working environment temperature    is lower, to ensure the service life.

3. Safety & Stability

4. High flexibility & Maximum simplicity of operation

5. Coordinated with HC’s patented multi-pouring systems, per batch liquid steel pouring out more times is available, which benefits foundries requirements of different size castings.

HC’s patented technology <Multi-pouring Mechanism>, is a kind of rod utilized to block the hole on ladle bottom, which can realize pouring through the bottom of ladle, make the pouring process easier, safer.Advantages of this kind mechanism: 1.Make one batch liquid steel with multiple pouring come true, which casting times is far more than sliding nozzle does. 2. The hot rod is mounted before pouring. Compared to cold rod, which will not be melted with liquid steel, and protect the plug rod from meltdown process, thereby, steel leakage can be avoided. 3. Implementation of hot rod is convenient, pressing down hand shank the pouring starts, otherwise, the pouring ends.

6. Automatic temperature sampling system is available, so that the operation is more safe and convenient.

7. HC’s furnaces are equipped with a variety of dust removal systems, can be based on environmental requirements of different countries support different forms of dust removal equipments.
