Embodiment Construction

[0028] The present invention will be further described in detail in conjunction with specific embodiments below.

[0029] The technical solution adopted in the present invention is: a production process of high-performance tool and die flat steel, comprising the following steps:

[0030] Step 1. Send the scrap steel and pig iron into the electric arc furnace. After melting, heat up to ≥1580°C. During the oxidation period, the amount of C removal is guaranteed to be ≥0.20%. The rate of C removal is 0.01% / min-0.03% / min. 0.10%;

[0031] Step 2: Send the molten steel into the LF furnace, adjust the slag, add C powder, Fe-Si powder and Si-Ca powder for reduction, fine-tune the composition after the temperature is ≥1580°C, and keep the slag in the furnace for ≥20 minutes after it turns white , after the ingredients are qualified and the temperature reaches 1670°C-1690°C, it will be released from the furnace;

[0032] Step 3. After pouring out 70%-80% of the slag, the molten steel ...

Abstract

The invention discloses high-performance tool mold flat steel. The high-performance tool mold flat steel comprises, by weight percentage, 0.35%-0.40% of C, 0.70%-1.0% of Si, 0.30%-0.60% of Mn, smallerthan or equal to 0.010% of P, smaller than or equal to 0.005% of S, 5.20%-5.70% of Cr, 0.40%-0.60% of Ni, 1.30%-1.50% of Mo, 0.90%-1.20% of V, smaller than or equal to 0.10% of Cu, smaller than or equal to 0.010% of the combination of As, Sn, Pb, Sb and Bi and the balance Fe and inevitable impurity elements. The yield of the produced tool and mold flat steel is high, the inherent purity degree ishigh, few impurities exist, the organization is uniform, various mechanical properties are high, the energy is saved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of alloy steel processing, and in particular relates to a production process of high-performance tool and mold flat steel. Background technique [0002] Die steel is a type of steel used to make molds such as cold stamping dies, hot forging dies, and die-casting dies. Its performance is mainly affected by material and heat treatment. It has very high requirements on the purity, cracks and mechanical properties of steel, and the harmful impurities such as P, S, H, O, N, As, Sn must also be strictly controlled. At present, in the common production process, multiple ingredients need to be used, so the ratio of each ingredient is difficult to control. Often the properties and parameters of mold steel after processing cannot meet the practical requirements, resulting in problems such as low yield. In the prior art, it is difficult to effectively solve the above problems. Contents of the invention [0003] The technic...
