Abstract

método de produção de material de aço para ferramentas de alta velocidade. é descrito um método para produzir um material de aço para ferramenta de alta velocidade tendo excelente capacidade de trabalho a quente, em que o enxofre (s) e o nitrogênio (n) são reduzidos para uma quantidade baixa, e uma quantidade desejada de cálcio (ca) é adicionada. o método de produção inclui: um primeiro processo para preparação de um aço fundido tendo uma composição de um aço para ferramenta de alta velocidade; um segundo processo para refino da escória do aço fundido preparado, para reduzir o s no aço fundido para 0,004% ou menos, em massa; um terceiro processo de adição de ca ao aço fundido com escória refinada, e de ajuste de ca no aço fundido para 0,005 a 0,015% em massa; e um quarto processo de moldagem do aço fundido adicionado com ca. de preferência, o aço fundido preparado no primeiro processo é refinado a vácuo, ou preferivelmente o n, no aço fundido antes de ser moldado no quarto processo, é reduzido mais ainda para 0,01% ou menos, em massaproduction method of steel material for high speed tools. a method is described for producing a high speed tool steel material having excellent hot-working capability, in which sulfur (s) and nitrogen (n) are reduced to a low amount and a desired amount of calcium ( ca) is added. the production method includes: a first process for preparing a molten steel having a high speed tool steel composition; a second process for refining the slag of the prepared molten steel, to reduce the s in the molten steel to 0.004% or less by weight; a third process of adding ca to molten steel with refined slag, and adjusting ca to molten steel to 0.005 to 0.015% by weight; and a fourth molding process of molten steel added with ca. preferably, the molten steel prepared in the first process is vacuum-refined, or preferably the n, in the molten steel before being molded in the fourth process, is further reduced to 0.01% or less by weight
