(54) СПОСОБ ВЫПЛАВКИ БЫСТРОРЕЖУЩЕЙ СТАЛИ(54) METHOD FOR MELTING QUICK-CUTTING STEEL

выпуском и, следовательно, -перец разливкой . Быстрорежущие стали, выдержанные при вышеуказанных температурах., хорошо разливаютс  при 144О-1490 С, т.е. температура металла перед выпуском составл ет 1450-1500°С.release and, therefore, pepper by pouring. High speed steels aged at the above temperatures are well cast at 144 ° -1490 ° C, i.e. the temperature of the metal before release is 1450-1500 ° C.

Раачивка быстрорежущих сталей при этих температурах приводит к образованию большего количества центров кристаллизации . Поэтому при затвердевании быстрорежущей стали, выплавленной по предложен юму способу, получаетс  более мелкое зерно и равномерное распре- целение карбидной фазы, что уменьшаетThe casting of high-speed steels at these temperatures leads to the formation of a larger number of crystallization centers. Therefore, when solidifying high-speed steel smelted according to the proposed method, a finer grain and uniform distribution of the carbide phase are obtained, which reduces

степень денпоитной ликвации, повышае технологичность стали и стойкость изгого шенного из нее режущего инструмента .the degree of denpoitic segregation, the improved manufacturability of steel and the durability of the cutting tool bent from it.

Способ осуществл ют следующим образом . В индукциониой печи емкостьюThe method is carried out as follows. In induction furnace capacity

60 кг выплавл ют опытную плавку быстрорежущей стали Р6М5. После расплавлени  шихты металл нагревают до 1720 С, раскисл ют алюминием в количестве60 kg of melted high-speed steel R6M5 melted. After the charge is melted, the metal is heated to 1720 ° C, deoxidized with aluminum in the amount of

0,6 кг/т, выдерживают 25 мин, быстро охлаждают в результате отключени  пе- чи и при 1490 С выпускают : в ковш. Металл при 1470 С разливают на два слитка массой по ЗО кг. Из одного слитка изготавливают образцы на гор чее кручение, другой слиток проковывают до диаметра 30 мм и получают из иего резцы.0.6 kg / t, incubated for 25 minutes, quickly cooled as a result of shutdown of the furnace and at 1490 C is released: into the ladle. The metal at 1470 C is poured into two ingots with a mass of 30 kg. Samples for hot torsion are made from one ingot, another ingot is forged to a diameter of 30 mm and produced from its cutters.

Качество металла, выплавленное по предлагаемому способу, сравнивают сThe quality of the metal produced by the proposed method is compared with

качеством металла, выплавленным по известному способу.the quality of the metal produced by a known method.
