___A shief metallurg of “TehnoIngeniring.RF” company write:
___The Beginning processes of the rebirth converters production was conditioned by possibility of the use in production become greater amount of the technical oxygen, got by factious reduction of the air on oxygen station. The Studies metalworker in the field of improvements converters production – an using the oxygen in mixture with air and the other gas at conservation of the principle blowing classical processes (from below) – did not yet provide the required decisions of the problem of the using converters processes in modern metallurgy. The Cardinal decision of the problem was a creation oxygen – an converters of the way production become with use the new principle of blowing – a presenting of blowing from technical oxygen overhand on surface processed in converter of the metal.
___The Technology of the oxygen – converters process was designed in Russia and Austria simultaneously. Transition on production become in deafbottoms converter with the main fireproof and presenting the oxygen overhand through metallic water – coolled furms has brought about scolded change the conditions converters melting trunks. The Exception from composition of blowing nitrogen, entered in converter in classical process with air blow, promoted increase an amount used in smelting of the heat so became the possible conversion cast iron with low contents of phosphorus and silicon, shown main source of the heat in tomass and bessemers process. Besides, manage vastly to raise the share of scraps, melted down in converter.
___At use instead of air of the technical oxygen with purity less 99,5% sharply fell the contents of the nitrogen in metal before limit, usual for open-hearth process and below. The Process turned out to be more flexible in respect of regulations slags mode in converter and possibilities of the removing the bad admixtures (the sulphurs and phosphorus) in contrast with tomass process. Was it thereby solved problem quality metal and of melting in converter become practically whole open-hearth of sortament.
___Simultaneously with removal defect classical converters of the ways, oxygen – converters way production by steels have saved their main value (high efficiency, small capital expenditures, simplicity of the equipment and service conveners shop). Besides, oxygen – converters process has allowed to use such ore place of birth, using which difficult under the other way production by steels, and has permitted the redistribution high manganese cast iron, redistribution chromise cast iron, cast iron with raised by contents of phosphorus and others. Value oxygen – an converters of the way has provided the high pace of development of this process. At present it is dominise in production by steels. This way melting more than 50% whole become (in the world).
___The Development an oxygen – converters way production by steels occurs toward the further improvement of the process with upper blowing, as well as new way to use the oxygen with fuel additive or other gas in converter. The Improvement oxygen – an converters of the way with upper blowing occurs toward mutating device and mode of blow, as well as slags mode melting trunks (last mainly as a result of moving the part of processes from converter in scoop and reduction amount slag in most converters process). Such actions is caused by imperfection of mixing metal and slag and insufficient mixing action flow of blow on the whole volume of the fluid metal in converter with upper blowing. This particularly characteristic of for converter of the most capacity.
