Abstract

The invention aims at providing a low carbon cast steel pellet low in raw material cost, uniform in shape, comparatively low in rigid deviation of metal texture and stable in clearing capability through optimizing a chemical composition including the containing volume of micro constituents. The low carbon cast steel pellet is characterized in that the low carbon cast steel pellet has the chemical composition of, by mass, 0.1 percent to 0.25 percent of C, 0.1 percent to 0.3 percent of Si, 0.4 percent to 1.0 percent of Mn, 0.3 percent to 1.0 percent of Cr, less than 0.05 percent of p, 0.05 percent of S, and the rest of Fe and unavoidable impurities.

Description

technical field

[0001] The invention relates to a carbon cast steel shot. In more detail, the present invention relates to a low-carbon cast steel shot with uniform shape, small deviation of metal structure and hardness, and stable shot blasting ability. Background technique

[0002] Conventionally, cast steel shot has been used in a wide range of applications. Cast steel shot is mainly used in a wide range of applications, including sand cleaning of castings, deburring of ferrous metal materials, removal of deposits, and removal of oxide films.

[0003] Cast steel shot is generally divided into high-carbon cast steel shot and low-carbon cast steel shot, and its chemical composition and quality are standardized. For example, Japan has regulations in JIS Z0311 (2004).

[0004] Since the high-carbon cast steel shot contains 0.80% to 1.2% of C, the quenching hardness can be improved, so it can be mechanically pulverized to produce scrap metal. Since crushed metal is widely u...
