Ladle Refining Furnances

Listing ID #4283542

Our firm is one of the prominent names, which is engaged in offering Ladle Refining Furnaces. Developed utilizing premium grade raw material, which is procured from dependable vendors of the market, this range is ideally applicable for refining of liquid steel which helps in producing high quality structural/alloy steel. Appreciated for decreasing the dissolved gas content, this range also helps in quick recovery of ferro-alloys. Along with this, the offered range is available with capacity ranging from 5 Ton to 50 Ton. Ladle Refining Furnaces are a proven technology used for producing alloy steel, desulphurizing liquid steel and for improving the productivity from a steel plant. Ladle Refining is a post-melting treatment that is after melting in either the Induction Melting Furnace or Electric Arc Furnace.

Whenever LRF is installed on-line, liquid metal is transferred from the main melting source to the LRF at a nominal tapping temperature and either Argon/Nitrogen is purged from the bottomapart from arcing (using electrodes) on the top to bring about homogeneity of liquid metal composition and temperature. Fused lime/CaSi is added to the liquid metal to reduce sulphur and bring it within acceptable limits. And temperature is raised for the next casting operation.

Ladle Refining of liquid metal is a proven technology to produce high quality steel. Ladle Refining Furnaces (LRFs) are used to desulphuriser steel, remove other impurities and hold the molten steel for casting operations. Without LRFs, higher tap temperatures are normally required from steel making furnaces due to heat losses during transfer and casting of liquid metal. LRF facilitates higher productive time to the melting furnace besides producing better quality of steel at lower cost.

When alloying is done in the LRF, the main melting furnace is freed from this activity providing more productive time to the melting equipment and this external treatment has a few distinct benefits like reduced alloy consumption, better lining life, excellent homogeneity of chemical composition & temperature and relatively lower energy cost. The normal LRF cycle lasts for about 40-50minutes depending upon the aim and final chemistry and desired temperature rise. Temperature can be raised in the LRF at the rate of 3-4OC per minute depending upon ladle condition and ferro-alloy additions that are carried out.

By providing a mean to refine outside of the steel making furnace, LRF provides many benefits including reduced alloy consumption, uniform temperature & properties and lower energy costs. In addition, a vacuum environment can be attained in LRF, which allows production of high quality alloy steel.
