Zusammenfassung: | The invention belongs to the technical field of metallurgy, and particularly relates to a preparation method of high-carbon high-alloy cold-working die flat steel. The preparation method of the high-carbon high-alloy cold-working die flat steel comprises the following steps that raw materials are smelted according to the element proportion of the high-carbon high-alloy cold-working die flat steel, and molten liquid is obtained; the molten liquid and the alloy are mixed for alloying and then sequentially subjected to LF refining and VD degassing treatment, and molten steel is obtained; the molten steel is subjected to continuous casting, and a continuous casting blank is obtained; and the continuous casting blank is sequentially subjected to one-heating-number rolling and annealing treatment, and the high-carbon high-alloy cold-working die flat steel is obtained. The preparation method provided by the invention is simple in process flow, the production cost is reduced, and the production efficiency is improved |
