Zusammenfassung:	PCT No. PCT/SU83/00018 Sec. 371 Date Jul. 19, 1984 Sec. 102(e) Date Jul. 19, 1984 PCT Filed Jun. 2, 1983 PCT Pub. No. WO84/02353 PCT Pub. Date Jun. 21, 1984.A process of making steel from solid metal iron-bearing materials, especially metal scrap, in an oxygen converter comprises heating and melting the charge by supplying a fuel and an oxidizing agent in the direction from the bottom upwardly and from the side through the thickness of the materials charged into the converter, as well as top feeding of the oxidizing agent, whereupon the melt is refined while a silicon-containing heat carrier is added thereinto. At the same time, the side and top blowing of oxygen is discontinued while the bottom blowing thereof is reduced.
