Following the shutdown of the old LTV Corp. facility, ISG Cleveland implemented an asset protection plan for restarting the furnaces. This article provides a brief overview of the start-up plan, as well as the expectations for the new company culture and its effect on iron producing.

The replacement of a snort valve at WCI Steel involved an industry survey as well as a look back at previous WCI experiences. Selection criteria and installation details for the new snort valve, silencer and operator are discussed.

A Web-based computer model that provides mass- energy balance analysis also considers the effects of nonequilibrium conditions that often occur in blast furnace reactions. The model provides sufficient information to determine the validity of instrumentation data, identify the casuses of furnace upsets and guide furnace operation.

Dofasco’s No. 4 blast furnace, a two-taphole furnace, adopted an alternating taphole casting practice in the mid-1990s. The constraints of a single-taphole practice, efforts to maximize two-taphole availability and the change in casthouse practices are discussed.
