Scientific-Technical Conference of Specialists in Blast-Furnace Smelting

A scientific-technical conference of specialists in blast-furnace smelting was held in Moscow on December 4–7, 2000 under the auspices of the Association of Blast-Furnace Operators, the Institute Chermetinformatsiya, and the International Union of Metallurgists. Specialists from more than 40 metallurgical companies, scientific-research institutes, and planning organizations in Russia, the Ukraine, and Kazakhstan met with representatives of companies from Slovakia and Germany to discuss the state of blast-furnace smelting and exchange ideas on how to promote its development. The convening of the conference was particularly symbolic for the year 2000, since the beginning of the third millenium should be marked by progress in every sphere of human activity. Veteran blast-furnace operators A. F. Borisov and B. N. Zherebin were among those in attendance.     

Optimum Slag Composition for the Blast-Furnace Smelting of Titaniferous Ores

Abstract

This work is the second part of an investigation aimed at gaining a wider knowledge of the problems met when smelting titaniferous iron ores in the blast furnace. Viscosity measurements of the lower melting slags in the lime-silica-titania-alumina system were studied in neutral atmos. and under reducing conditions. Slag thickening was found to take place in the presence of C. The thickening rate varied with the comp, basically and temp. of the slag. The optimum slag comp. was considered to be that of a slag whose viscosity did not exceed 5 poises after heating in the presence of C at 1500°C for at least 2 hrs.
