Description
Известные способы выплавки вольфрамосодержащей стали в мартенов ских печах, вследствие тугоплапкости и большого удельного веса ферровольфрама привод т к замедлению растворени вольфрама и заметной его потере.The known methods of smelting tungsten-containing steel in open-hearth furnaces, due to the refractoriness and high specific weight of ferro-tungsten, slow down the dissolution of tungsten and its noticeable loss.
Отличительна особенность оп1исываемого способа состоит в том. что пр.и выплавке вольфрамосодержащей стали примен ют легкоплавкие комплексные W-Cr или W-Cr-Si-Al ферросплавы.A distinctive feature of this method is. that, in the production of tungsten steel, low-melting complex W-Cr or W-Cr-Si-Al ferroalloys are used.
Такой способ обеспечивает выплавку в ольфрамосодержащей стали в основных и кислых мартеновских печах.This method provides smelting in alum-containing steel in the main and acid open-hearth furnaces.
С целью создани возможности расплавлени вольфрамосодержащей присадки в услови х мартеновской плавки вольфрам вводитс в мартеновскую ванну в виде врльфрамосодержапдей лигатуры, представл ющей собой легкоплавкий комплексный W-Cr или W-Cr-Si-Al ферросплав.In order to create the possibility of melting a tungsten-containing additive under the conditions of open-hearth melting, tungsten is introduced into the open-hearth bath in the form of a vertical base containing ligature, which is a low-melting W-Cr complex or W-Cr-Si-Al ferroalloy.
Присадка вольфрамосодержащей лигатуры в печь производитс по ходу плавки после или одновременно с предварительным раскислением ваннм.The addition of a tungsten-containing ligature to the furnace is carried out during smelting after or simultaneously with the preliminary deoxidation of the baths.
Верхний предел содержани вольфрама в лигатуре составл ет , 1мерно 38-45% ,а содержание хрома до 30%, что не вызывает заметного повышени температуры ллавлени сплава.The upper limit of the content of tungsten in the ligature is 1D 38-45%, and the content of chromium is up to 30%, which does not cause a noticeable increase in the temperature of fusion of the alloy.
Понижение удельного веса вольфрамовой лигатуры может осуществл тьс -введением в состав лигатуры до 10% и до 5% алюмини . В этом случае необходимость введени в ванну специальных раскислителей дл предварительного раскиспени исключаетс .Reducing the specific weight of tungsten ligatures can be accomplished by introducing into the composition of ligatures up to 10% and up to 5% aluminum. In this case, the need to add special deoxidizing agents to the preliminary deoxidation in the bath is excluded.
