Изобретение относитс к внеыечной обработке металлов и сплавов.This invention relates to the extra-machining of metals and alloys.
По основному авт. ев J6202I9I известно устройство дл вакуумировашш сталей и сплавов с одновремехшой обработкой их в столбе жидкого шлака.According to the main author. The J6202I9I device is known for vacuuming steels and alloys with simultaneous treatment of them in a column of liquid slag.
Однако известное устройство не обеспечивает достаточно полного рафинировани металла вследствие ухудшени рафинирукщих свойств шлака в ходе процесса з-за обогащени его окислагли железа, марганца , кремни и т.п. Кроме того, при окислительном процессе реакции обезуглероживани не получают должного развити However, the known device does not provide a sufficiently complete refining of the metal due to the deterioration of the refining properties of the slag during the process of enriching its oxidized iron, manganese, silicon, etc. In addition, during the oxidative process, the decarburization reaction does not receive proper development.
С целью вдувани активного газа или порошкообразного материала предлагаемое устройство снабжено адрмами, установленными в верхней части шлакового рукава.In order to inject the active gas or powdered material, the proposed device is equipped with adrums installed in the upper part of the slag sleeve.
На фиг. I показана предлагаема установка дл внелечного рафи .нировани жидкого металла; наFIG. I shows the proposed plant for an off-site refining of liquid metal; on
фиг. 2 - то же с коллектором дл подачи порошка.FIG. 2 - the same with a collector for feeding powder.
Установка состоит из копильника I с металлом, вакуумной камеры 2 с вакууьшлотныл фланцевым соединением дл стыковки с копильником ,вертикального нефутеровашюго шлакового рукава 3, работающего в гарниссашюм режиме, фурменного водоохлаждаемого коллектора 4 дл подачи активного газа шш дл вдувани порошков, вмонтированного в шлаковый рукав, и приемника 5.The installation consists of a metal case I with metal, a vacuum chamber 2 with a vacuum flange connection for docking with a pigmer, a vertical non-lining slag sleeve 3 operating in the garnissashy mode, a water-cooled tuyere stock 4 for supplying active gas shsh for blowing powders mounted into the slag sleeve and receiver 5.
фурмы дл подачи газа или порошков располагаютс по окружновти поперечного сечени шлакового рукава . Их сечение и шаг выбирают в загвисимости от необходимого расхода газа и порошковых реагентов. Высота шлакового рукава при этом выбираетс с учетом образовани в его надфуменнои части газо-чплаковой смеси определенных параметров.tuyeres for supplying gas or powders are located along the circumference of the slag sleeve. Their cross section and pitch is chosen depending on the required flow of gas and powder reagents. In this case, the height of the slag sleeve is selected taking into account the formation of a gas-flame mixture of certain parameters in its supranuclear part of the gas.
Место расположени фурменного коллектора по высоте шлакового рукава при восстановительном процессеLocation of the tuyere collector at the height of the slag sleeve during the recovery process
определ етс видом прюлеп емого восстановител .determined by the type of spun-down reductant.
При окислительно-восстановитедьном процессе фурменный коллектор устанавливают в верхней части шлако- 5 вого рукава. Это позвол ет при подаче окислител в виде газа, создать локальную окислительную зону в столбе шлака.In the case of the redox process, the tuyere collector is installed in the upper part of the slag sleeve. This allows, when the oxidant is supplied in the form of a gas, to create a local oxidation zone in the slag column.
