Embodiment

[0016] The sand casting production method of the abrasive casting of the present embodiment comprises the following steps:

[0017] (1) Material ratio (weight%): carbon 3.6, chromium 1.2, manganese 1.0, silicon 1.6, nickel 0.1, molybdenum 0.1, copper 0.8, iron balance;

[0018] (2) Smelting;

[0019] (3) Casting;

[0020] (4) Cold treatment. About 10 minutes after the casting is completed, open the upper box of the blank sand box, remove the molding sand on the blank, and expose the tooth surface. When the temperature of the tooth surface drops by 900°C, sprinkle water on the tooth surface for cooling treatment. Then cool naturally.

[0021] The casting production process of the grinding disc is simple, the manufacturing cost is low, the product performance is good, and the wear resistance and service life of the grinding disc are improved.

Abstract

The invention discloses a molding sand casting production method of an abrasive disc casting. Materials for producing the abrasive disc casting comprise 2.8-3.6wt% of C, 0.6-1.2wt% of Cr, 0.5-1.0wt% of Mn, 1.6-2.0wt% of Si, 0.1-0.5wt% of Ni, 0.1-0.2wt% of Mo, 0.5-0.8wt% of Cu, and the balance of Fe. The abrasive disc casting is produced through the processes of smelting, casting, and chilling treatment through sprinkling water to gear surfaces. The production method has the advantages of simple process and low production cost, the abrasive disc casting has good performances, and the method improves the wear resistance and prolongs the service life of the abrasive disc.

Description

[0001] technical field [0002] The invention belongs to the technical field of casting, and in particular relates to a casting production process of grinding discs. [0003] Background technique [0004] The grinding casting manufacturing process includes at least the manufacturing and pouring process of the casting mold. In the current manufacturing process of grinding discs, it is easy to produce sand sticking defects, sand washing defects and coarse structure, and thick and large ductile iron parts have a tendency to shrinkage and porosity. [0005] Contents of the invention [0006] In order to overcome the above-mentioned technical problems existing in the prior art field, the object of the present invention is to provide a sand casting production method of grinding disc castings, which has simple production process, low manufacturing cost, good product performance and improved wear resistance of grinding discs. sex and longevity. [0007] The sand casting produc...
