It is proposed that results obtained from the experimental-theoretical solution of a three-dimensional problem on the plastic flow of metal be used to determine the main reasons for variations in the output of usable metal products. The results were obtained on the basis of models of quality. Modeling was performed to analyze a technology for rolling a broad range of structural-grade carbon-steel rounds that then undergo cold extrusion and upsetting. The rounds are rolled on a light-section mill and a rod mill at the EVRAZ ZSMK combine. It is shown that under the given production conditions the value of the integral index of rolled-product quality which characterizes the output of usable metal over long periods of time is determined mainly by simultaneous processes that involve the healing (or deepening) of surface defects, the formation of cracks on the surface of the semifinished products, nonuniform wear of the grooves of the rolling-mill passes, and depletion of the reserve ductility of the metal in the region where it comes into contact with the grooves. The results have been used to substantiate corrective measures taken in the multi-stage manufacture of rolled products at the combine. The measures were substantiated within the context of the combine's existing quality-control system. © 2014, Springer Science+Business Media New York. Source

Results are presented from laboratory studies of the sintering of a two-layer charge in which the solid fuel is separated into different fractions. It was established that a reduction in the top layer’s content of the –0.5-mm fraction from 45% to zero is accompanied by a decrease in the unit productivity of the sintering machine and increases in the output of sinter and its strength characteristics. The indices of the sintering operation and sinter quality remain the same as in the standard technology when fuel content is decreased from 7.5 to 7.1–7.2%. Introduction of the technology that was developed will makes it possible to decrease the unit consumption of solid fuel for sinter production by 4%. © 2014, Springer Science+Business Media New York.
