High-wear-resistance regenerated synthetic cast iron forged steel ball and production process thereof

Abstract

The invention discloses a high-wear-resistance regenerated synthetic cast iron forged steel ball and a production process thereof. The high-wear-resistance regenerated synthetic cast iron forged steelball comprises the following raw materials, by mass percent, 0.95% to 1.05% of C, 0.25% to 0.45% of Mn, 0.15 to 0.35% of Si, 1.40 to 1.65% of Cr, 0.2 to 0.30% of Ni, 0.05% to 0.10% of Mo, 0.15 to 0.25% of S, 0.15 to 0.025% of P and the balance Fe or a small amount of residual elements; and the invention further provides the high-wear-resistance regenerated synthetic cast iron forged steel ball and the production process thereof. The production process comprises the following step of (1) burdening: preparing a raw material according to the following chemical components in percentage by mass: 0.95%-1.05% of C, 0.25%-0.45% of Mn and 0.15%-0.35% of Si. According to the high-wear-resistance regenerated synthetic cast iron forged steel ball and the production process thereof, desulfurization ina furnace can be achieved, a nodulizing agent can be saved, ductile iron production is stabilized, and high-quality nodular cast iron is obtained.

Description

technical field [0001] The invention relates to the technical field of steel ball production, in particular to a high wear-resistant recycled synthetic cast iron forged steel ball and a production process thereof. Background technique [0002] High wear-resistant recycled synthetic cast iron grinding balls are mainly used to replace the original No. 45 steel forged steel balls. Compared with No. 45 steel forged steel balls, the wear resistance is increased by 3 to 10 times. The use of this product can greatly save steel consumption. save resources. In the prior art, during the smelting process of steel balls, a large amount of sulfur will be produced in the furnace, and the production of the balls is unstable, and high-quality nodular cast iron cannot be obtained. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a high wear-resistant recycled synthetic cast iron forged st...
