Analysis of the Effect of Organizational Factors on Blast Furnace Operating Indices

Resumo

The effect is analyzed of organizational factors on blast furnace operating indices under contemporary intense smelting conditions: current banking time, fanning time, and compliance with the discharge schedule. The quantitative effect of these factors on blast furnace performance was established more the thirty years ago and needs adjustment. It is demonstrated that production losses associated with banking depend on duration and number, and production losses associated with fanning depend on duration, amount, and degree of blast pressure reduction. Dependences (equations) are determined for production loss connected with banking and fanning. The effect of banking and fanning time on the change in equivalent coke consumption is determined. Values obtained differ from those used previously. The effect of discharge schedule on furnace performance and specific coke consumption for AO EVRAZ NTMK loses its relevance.
