Abstract

The invention relates to the field of cast steel, in particular to cast steel. The cast steel is prepared from the following raw materials by mass percent: 0.31%-0.36% of carbon, 0.35%-0.6% of silicon, 1.1%-1.4% of manganese, 0-0.035% of phosphorus, 0-0.035% of sulfur, 0.03%-0.08% of aluminum and the balance of iron. The invention further relates to a production technology of the cast steel. According to the cast steel, the technical problem of low strength of existing cast steel is solved; the tensile strength, elongation percentage, reduction of cross section and impact toughness of the caststeel are 20%-50% higher than similar products; and the cast steel is mainly applied to cast of engineering machinery parts.

Description

technical field [0001] The invention relates to the field of cast steel, in particular to a cast steel and a production process thereof. Background technique [0002] There are many existing cast steel products, and there are many types of their proportions, and the formula is adjusted according to the purpose of the characteristics. For example, Chinese Patent No.: CN201210525541.7 discloses a cast steel, and the cast steel The chemical composition and its mass percentage are: carbon: 0.15-0.2%; silicon: 0.3-0.55%; manganese: 1.1-1.45%; chromium: 0.35-0.5%; nickel: 0.4-0.9%; titanium: 0.04-0.06% ; Rhenium: 0.02-0.04%, the rest is composed of iron, the invention has the advantages of low cost and strong impact resistance. However, the usual defect of existing cast steel is its low strength. It is often difficult to meet the strength requirements of construction machinery parts, resulting in the low life of existing construction machinery parts. How to improve its strength h...
