Conclusions At the Ukrainian Scientific-Research Institute of Refractories, in collaboration with Ukrogneupornerod and the Chasov-Yar Refractories Combine, methods have been developed for improving the service properties of mullite-corundum slabs and increasing their reliability and stability in operation. The commercial production of mullite-corundum slabs has been organized.The slabs are being successfully used in stopperless steel pouring at the Il'ich Metallurgical Works, Zhdanov, and at the Donetsk Metallurgical Works.To increase the stability of mullite-corundum slabs to two or three meltings, it is necessary to organize the commercial production of these articles with alumina-enriched binder.Translated from Ogneupory, No. 5, pp. 25–29, May, 1981.  相似文献

Experimental study on the effect of strain rate on discontinuous flow and mechanical characteristics of the high-nitrogenous steel Kh23AG19F has been performed. Within the range of strain rates from 4.62 · 10-5 to 1.85 · 10 -4 s-1, discontinuous flow, reflected by serration on the tensile diagram, is chiefly determined by intergranular deformation mechanisms. Under strain rates over 1.85 · 10-2 s-1, combined deformation modes prevail, which cause a change in the character of discontinuous flow and transform a serrated tensile diagram into a wavy graph, with the yield stress of steel increased significantly.  相似文献
