Изобретение относитс к получению быстрорежущих марок сталей.This invention relates to the production of high-speed steels.
Известен способ выплавки быстрорежущей стали, защищенный основным авт. св. JMb 438707, заключающийс в расплавлении шихты, рафинировании , окончательном раскислении металла алюминием, введении циркони в количестве 0,09-0,11% (по расчету) с последующей выдержкой металла в ковше в течение 5-8 мин.There is a method of smelting high-speed steel, protected by the main ed. St. JMb 438707, consisting in melting the charge, refining, final deoxidation of the metal with aluminum, introducing zirconium in an amount of 0.09-0.11% (by calculation), followed by holding the metal in the ladle for 5-8 minutes.
Описываемый способ вл етс развитием известного, защищенного основным авторским свидетельством, и отличаетс от него тем, что перед присадкой циркони ввод т азот до получени его в металле в количестве 0,04- 0,09% Это повышает качество металла, выход годного и стойкость инструмента.The described method is the development of a well-known, protected basic copyright certificate, and differs from it in that before the zirconium additive nitrogen is introduced before its production in the metal in the amount of 0.04-0.09%. This improves the quality of the metal, the yield of the tool and the durability .
Описываемым способом выплавл ли сталь Р6М5 в печи емкостью 25 т. После расплавлени шихты, рафинировани и окончательного раскислени стали алюминием, в металл при 1525°С вводили в виде азотированного феррохрома 0,048% азота, а перед выпуском плавкиBy the described method, steel R6M5 was smelted in a furnace with a capacity of 25 tons. After the charge was melted, the steel was refined and finally deoxidized with aluminum, 0.048% of nitrogen was introduced into the metal at 1525 ° C, and
В ковщ присаживали цирконий в количестве 0,11% (по расчету). После выпуска плавки металл выдерживали в ковше в течение 6 мин и разливали в изложницы дл слитков массой 1150 кг. VZirconium was deposited in the carpet in an amount of 0.11% (by calculation). After melting, the metal was kept in a ladle for 6 minutes and cast into molds for ingots weighing 1150 kg. V
Сталь, выплавленную описываемым способом , можно нагревать под закалку на 15- 20°С выше обычных пределов; азот, раствор сь при нагреве в твердом растворе, уменьшает коэффициент диффузии элементов, способству его большой легированности. Все это приводит к повышению стойкости инструмента , изготовленного из быстродействующей стали , полученной описываемым способом.Steel melted by the described method can be heated for quenching by 15-20 ° C above normal limits; Nitrogen, dissolving when heated in a solid solution, reduces the diffusion coefficient of elements, contributing to its high doping. All this leads to an increase in the durability of a tool made of high-speed steel, obtained by the described method.
