How does the preheating of nitrogen affect the mass of gas added to the supersonic jet that enters an oxygen converter? To establish the influence of this and other factors, an appropriate system of gasdynamic equations is solved. © 2011 Allerton Press, Inc. Source

The factors affecting the thermal state of mold walls in continuous slab-casting machines are analyzed. On the basis of the proposed method and model, the design parameters of a radial mold with slot channels and the parameters of the coolant (water) flow may be calculated. © 2011 Allerton Press, Inc.

The production of rolled bar and complex profiles from continuous-cast slab is considered. The proposed method includes water-based cooling systems and the introduction of consumable macrocooling units in the melt. This approach significantly reduces the axial segregation of chemical elements and the structural inhomogeneity of the blank, improves the plastic properties and improved strength of the rolled bar, and reduces the metal consumption. © 2010 Allerton Press, Inc.

Physical simulation of steel injection in the intermediate ladle of a continuous slab-casting machine permits the determination of the supply channels for the bottom tuyere such that bubble injection of the metal extends over the whole bath depth in the intermediate ladle and the gas bubbles reliably pass through the slag coating layer. Practical results are presented for the proposed tuyere. © 2010 Allerton Press, Inc. Source
