FIELD: metallurgy. SUBSTANCE: invention relates to metal scrap remelting and refining of pig iron into steel. Equipment has vessel in the form of lined laddle suspended from hollow half-axles. Side walls of ladle have ducts in the form of even number of multistart spirales. Each pair of ducts has common outlet into lower part of vessel. One of ducts of pair is connected to source of combustible gas, the other one - to source of air or oxygen. Gas is fed into spiral ducts through hollow half-axles. EFFECT: simplified design, improved operational efficiency of equipment. 2 dwg
