Problems solved by technology

Existing cut shot pays more attention to hardness and toughness, and there is little research on corrosion-resistant cut shot. Due to the large amount of use in actual production, foundry processing manufacturers often reserve a large amount of cut shot for use. , causing a large amount of cut pellets to be rusted, corroded, and scrapped, resulting in a lot of waste. Therefore, the present invention studies a corrosion-resistant cut pellet formula, and takes both hardness and toughness into consideration.

Abstract

The invention provides a corrosion-resistant cut shot and a machining method thereof. A compound of the elements such as chromium, molybdenum and tungsten in the formula is effectively resistant to corrosion, is mainly resistant to acid, and particularly has an obvious resisting effect on monobasic acid like hydrochloric acid. The machining method of the corrosion-resistant cut shot is more refined, aerial fog machining is combined with cutting, quenching and tempering are integrated, and all indexes of a cut shot finished product are excellent.

Description

technical field [0001] The invention relates to the field of shot cutting processing, in particular to a corrosion-resistant cutting shot and a processing method thereof. Background technique [0002] Cut shot is a metal abrasive necessary for surface processing. It is mainly used in shot blasting equipment. Shot blasting equipment shoots cut shot to the surface of the casting at high speed to remove rust and burrs on the surface of the casting for surface treatment. Existing cut shot pays more attention to hardness and toughness, and there is little research on corrosion-resistant cut shot. Due to the large amount of use in actual production, foundry processing manufacturers often reserve a large amount of cut shot for use. , causing a large amount of cut pills to be rusted, corroded, and scrapped, resulting in a large amount of waste, so the present invention studies a corrosion-resistant cut pill formula, and takes hardness and toughness into consideration.
