Изобретение относитс  к области получени  быстрорежущих марок сталей.This invention relates to the field of producing high-speed steels.

Известен способ выплавки быстрорежущих марок стали, заключающийс  в переплаве собственных и близких по химическому составу отходов с применением кислорода.The known method of smelting high-speed steel is the remelting of its own and similar in chemical composition of waste using oxygen.

Сущность способа заключаетс  в расплав-, лении шихты, рафинировании и раскислении металла в печи алюминием.The essence of the method consists in melting, blending, refining and deoxidation of metal in a furnace with aluminum.

Однако такой способ не обеспечивает получение достаточно пластичного литого металла и приводит к потере выхода годного.However, this method does not provide enough plastic ductile metal and leads to a loss of yield.

С целью устранени  указанных недостатков предлагаетс  способ выплавки быстрорежущей стали, включающий расплавление шихты, рафинирование, раскисление металла в печи алюминием и введение в процессе выпуска металла с температурой 1510°-1540°С циркони  в количестве 0,09-0,11% (по расчету) с последующей выдержкой металла в ковше в течение 5-8 минут.In order to eliminate these drawbacks, a method of smelting high-speed steel is proposed, including melting the charge, refining, deoxidation of the metal in the furnace with aluminum and introducing zirconium in the quantity of metal with a temperature of 1510 ° -1540 ° C in the amount of 0.09-0.11% ) followed by aging of the metal in the ladle for 5-8 minutes.

Пример. Быстрорежущую сталь за 2- 3 минуты до выпуска плавки раскисл ют алюминием , введенным на штангах в количестве 0,3-0,5 кг/т стали, перемешивают железными гребками и при температуре 1510-1540С выпускают в ковш, во врем  выпуска в металл ввод т цирконий 0,09-0,11% по расчету (в виде силикоциркони ), затем металл перед разливкой выдерживают в ковше в течение 5-8 минут и разливают в изложницы дл  слитков массой 700-1200 кг.Example. High-speed steel 2–3 minutes prior to the release of smelting is deoxidized with aluminum introduced on the rods in an amount of 0.3-0.5 kg / t of steel, mixed with iron strokes and at a temperature of 1510–1540 ° C is released into the ladle t zirconium 0.09-0.11% by calculation (in the form of silicocyrconium), then the metal is cast in a ladle for 5-8 minutes before casting and cast into ingots for ingots of 700-1200 kg.
