The report considers possible action of the raising/increase of production capacity of oxygen converters. Given the types of technological operation on lining oxygen converters care shortlist, identified relations production capacity aggregates dependence on endurance lining. Using the analysis of production indicators and create graphics with approximation-ratio, in report showed than high-endurance lining that rise outage by execution technological operations - decline of production capacity occuring. In report calculated optimum-endurance lining converters, smelting steel. Produced calculation extension of terms terms repair intervals main and auxiliary machinery of converter-workshop by maximum loading workshop. According the calculation, showed decline volume of outage at repair machinery, relevated raising/increase of production capacity metallurgy aggregate, also decrease cost price steel production on account economy materials, year-raising production of steel indicators. This research and his direction of development is capability using outlined actions on any metallurgy plant, exploited oxygen converters.
