Description
II
Иэофетение относитс к металлургии, преимущественно черной, и может быть испопоьзовано при подготовке стружки высоколегированных сталей, содержащей масло, к плавлению в электропечах.Electrofusion refers to metallurgy, mostly black, and can be used in the preparation of chips of high-alloy steels containing oil, to melt in electric furnaces.
В современной металлургической щэомьшщенности при выплавке сталей и ферросплавов в качестве шихты широко примен етс стружка легированных сталей , подвергаема перед плавкой тепловой обработке дл удалени содержащегос в ней масла.In modern metallurgy of the smelting of steels and ferroalloys, chips of alloyed steels are widely used as a batch, which is subjected to heat treatment before melting to remove the oil contained in it.
Извести способ тепловой обработки легковесной шихты, например стружки Легированных сталей, содержащей масло, заключакицийс в ее нагреве до 6ОО80О С .Lime is a method of heat treatment of lightweight charge, for example, chips of alloyed steels containing oil, concluded in its heating to 6OO80O С.
Нагрев производитс в две стадага: вначале стружку нагревают до 2504ООС , выдерживают при этой талп атуре до прекращени дымообразовани , и затем продолжают нагрев до окончательной температуры 6ОО-80О С til The heating is carried out in two stages: first, the chips are heated to 2504 ° C, they are kept at this talp until the smoke stops, and then the heating is continued to the final temperature 6OO-80 ° C With til
Однако данный способ обработки не позвол ет получать быстрый нагрев кусочков стружки из-за необходимости прекращени нахрева при достижении стружкой температуры 25О-4ОО С и ее выдерживании в этом температурном интервале до 1фе1фащшги дымообразован .However, this treatment method does not allow for quick heating of the chip pieces due to the need to stop the warming up when the chips reach 25O-4OO C and it is kept in this temperature range up to 1f 1 smoke.
Известен также способ тепловой обработки металлических отходов, наприм лома, заключающийс в нагреве его до There is also known a method of heat treatment of metal waste, for example scrap, which consists in heating it to
10 и выше путем продувки его газообразным тешоноситепем, имеющим т« пературу 115О°С 2 ,10 and higher by purging it with gaseous teshonositepem, having a temperature of 115 ° C 2,
Однако известный способ непригоден дл тепловой обработки стружки, так как However, the known method is unsuitable for heat treatment of chips, since
ts не предотвращает возгорание масла и окисление, стружки.ts does not prevent ignition of oil and oxidation, chips.
Цепью изобретени вл етс ;гатевсификаци очистки стружки и предот ащ ние ее окислени .The chain of the invention is to force chip cleaning and prevent its oxidation.
2020
Поставленна цель достигаетс тем, что стружку предварительно увлажн ют до .% содержани воды, а в ка- честве теплоносител используют продувThe goal is achieved by the fact that the chips are pre-moistened to.% Water content, and blowing is used as a heat carrier.
