Oxygen Rich Side Blown Melt Melting Furnace
Contact UsThe oxygen rich side blown molten pool melting furnace is an efficient and energy-saving steel melting equipment. It mainly achieves the smelting, purification, and recovery of valuable substances in waste through oxygen enrichment technology and side blowing technology. Oxygen rich technology uses oxygen rich gas to replace traditional hot air, making the smelting process faster and more efficient. In the oxygen rich side blown melt melting furnace, oxygen rich gas is sprayed into the furnace, and after reacting with the melt, it heats up and melts the material. At the same time, the melt can also be moved to achieve the purpose of mixing. Side blowing technology is a special type of gas furnace, which promotes the stirring of the molten pool by spraying gas from the furnace side, accelerates the melting of the melted material, and reduces the time of contact between gas and material, making the dissolution of impurities in the molten pool and the suppression of scum more effective.
