Submerged arc welding is a complex metallurgical process with temperature of nearly 2000 ∘C (a much higher than that in traditional steelmaking) and different phases, including flux (slag), metal, plasma. Flux serves vital functions order to produce the weld metal desired qualities. It well known understandings thermodynamic properties regarding slag are essential aid design optimization. Actua...

Ladle refractories were subject to repeated chemical erosion and physical scouring by various hot fluids such as steel slag, liquid steel, argon oxygen. Firstly, the heat transfer model of ladle wall was established, refractory under different corrosion conditions analyzed. The relationship between residual thickness lining temperature field outer surface established. Secondly, a set infrared t...

The recycling options of spent MgO-C refractories from an electrical arc furnace (EAF) have been evaluated. The economic, quality of spent refractories and products made from it, the ease of implementation of a recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a foaming sla...

With the development of energy control system iron and steel enterprises, urgency solving problem resource saving steelmaking processes increases, taking into account reconfiguration production to a new task, intensification recycling raw materials, as well reducing waste intensity production. The way solve is creation computer system. It allows one analyze state refractory converter lining, ca...
