Abstract. Results of the analysis of physical-chemical properties of sinter and pellets are presented. It shows that at BF transition to operation with high proportion of acidacid pellets in furnace charge, it is necessary to change the basic parameters of the slag mode as well as furnaces loading practice.

Irregularities in Blast Furnace during Operation. For a stable and efficient operation of a blast furnace, smooth and uniform movement of burden materials downward and movement of furnace gases in the upward direction is very important.
The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air …
The disruptive effect of Blast Furnace was short lived: it was a matter of too few resources and too short a time. The four-month operation depressed coca prices below production costs, but things returned to normal at the end of the operation.
The zinc furnace permits treatment of complex zinc-lead ores. Earlier attempts with high CO furnace gas resulted in low thermal efficiency and reduction of iron oxides. The lead splash condenser, developed by Imperial Smelting, has permitted zinc to be condensed from blast-furnace gas high in CO 2 ...
