What are the main applications and fields of cast steel shot? Is it really true that the rounder the better?

　　Steel structure construction enterprises: Steel structures must be rust removed before use to meet the structural requirements stipulated by the state. The pass-through shot blasting machine adopts a fully automatic cleaning method, which does not require manual rust removal and reduces the environmental pollution problem of pickling. .

　　Hardware factory and electroplating factory: Because both hardware factory and electroplating factory require the surface of the workpiece to be clean, flat, and lubricated, the shot blasting machine can solve these problems.

　　Hardware factories, electroplating factories, and motorcycle parts factories: the workpieces are small, and drum-type shot blasting machines and crawler-type shot blasting machines are suitable for use, depending on the situation.

　　Valve factory: Since the workpieces in the valve factory are all cast, they all need cast steel shot to be polished and polished in order to be clean, lubricated, and smooth. This requires shot blasting machinery to clean up these impurities. Available machinery: rotary table type, hook type shot blasting machine.

　　During the process of granulating steel balls, the molten steel is cooled from liquid to solid and condensed during the cooling process. This kind of expansion is carried out at random, and it is not equipped with a riser to prevent the expansion of the steel ball after being condensed like a cast part. The reduced volume fills the molten steel, thus producing oblate particles with dents on the surface. These particles have undergone sufficient contraction and are not round in appearance but have high density. Steel balls that have not undergone sufficient contraction have concentric sides. The strength is good, but the structure is high-density and has internal defects such as casting defects and shrinkage porosity.

　　In terms of the actual application effect of cast steel balls, the rounder the steel balls are, the higher they are. Steel balls are generally used in the eradication industry. The eradication efficiency of steel balls with high concentricity is lower than that of rolled-up steel balls. The throwing kinetic energy E=1/2mv2, the ball with poor concentricity is well packed and arranged with high density, so the same volume, the mass m is large, the impact kinetic energy is high, and it is not fragile; on the contrary, the steel ball with good concentricity is not arranged easily High density, small particle mass, low mechanical energy, and brittle.
