The hereditary effect of the structure of a wire rod on the structure and physicomechanical properties of the steel 08G2S wire produced by rolling with shear is studied in comparison with the wire produced according to the standard technology in OAO Metal Steel Krivoi Rog. © 2011 Pleiades Publishing, Ltd.

Systems for reducing the width of continuous-cast slab supplied to broad-strip hot-rolling mills are reviewed. It is found that the use of vertical scale removers with smooth rollers, without smoothing in horizontal rollers, is laborious and ineffective. The use of smooth vertical rollers and a series of horizontal rollers, which is a configuration often used outside Ukraine, permits reduction in slab width by no more than 150–200 mm. Systems with vertical grooved rollers and horizontal smoothing rollers prove the best. Optimal conditions for reducing slab width are proposed, and parameter values of the corresponding equipment are recommended for the 2000 mill. © 2014, Allerton Press, Inc.

TSK-K-25 slag-forming mixture is chosen for the production of 500 × 500 mm square billet on a vertical continuous-casting machine. This mixture permits the casting of 45XΓMA steel at reduced speed (0.07-0.14 m/min). © 2011 Allerton Press, Inc.

Increase in barrel length of the working rollers from 3100 to 3400 mm is proposed in the 3000 mill, without change in barrel length of the supporting rollers (2980 mm) or in the structure of the cell. Calculations of the pressure between the rollers and the transverse thickness variation of the rolled metal when the barrel length of the working rollers is 3100 and 3400 mm shows that the maximum pressure between the rollers is increased by 6-8% for 3400-mm working rollers with rolled sheet of maximum width 3200 mm; the rolled material is concave. To obtain a convex cross section, the depth of the bevel of the edges of the supportingroller barrel is doubled. Increasing the length of the working rollers in the 3000 mill at PAO Mariupol'skii Metkombinat im. Il'icha permits the production of commercial sheet with a width up to 3000 mm. © 2013 Allerton Press, Inc.

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.
