A Duration of smelting

___A shief metallurg of «TehnoIngeniring» company write: 
___A main technician economic factor of smelting become in oxygen converter are their capacity and prime cost by steels. At quality of the metal must completely be up to quality standard. Functioning of the converter characterize annual and sentry by its capacity. Duration, or cycle smelting trunks is defined by time between consequent potting of cast iron in converter and forms from duration of blowing and auxiliary operation (the loading of scrap, potting of cast iron, plum of the metal and slag, waiting result of analysis of the metal and adjustments of its composition and the temperature).
___A Duration of smelting trunks in oxygen converter not proportional its capacities, but increases with increasing the capacities more slowly. This defines more high efficiency converter to big capacity in unit of time. Output suitable bullion depends on losses of the metal at blowing and way of pouring. In most cases he forms 89 — 91% from mass of metallic shicht. The Least losses of the metal get when use the machines of unceasing pouring by steels. The Number worker day at year depends on organizations of the work in convertered shop. At presence in shop two constantly working converter and the third, residing under repair, number worker day at year on working converter take equal 354 (rest on repairs). Duration of the repair of the converter with full change of fireproof forms before 100 hours.
___Prime cost by convertered steels forms from cost of metallic shicht (cast iron, scrap, ferro-alloys), additional material (lime, ore, bauxite, fluorspar) and redistribution. The Cost of the redistribution includes the costs on fireproofs, oxygen, electric power, removable equipment, salary, amortization of the main means. The Correlation between separate specified article following; cost of metallic shicht forms before 86% overall value, additional material — before 3%, redistribution — before 19%. What shows the analysis of the structure to prime cost, convertered process takes advantage of open-hearth on cost of the redistribution, which can be nearly in two times less, as well as cost to electric powers and fuel, refractory and auxiliary materials.
