The standard for selecting steel pellets is mainly to look at the workpieces you want to clean. Non-ferrous metals are generally made of aluminum pellets or stainless steel pellets. Steel shots are used for ordinary steel weldments, castings, and steel. The larger the diameter of the steel shot, the higher the surface roughness of the cleaned, but the cleaning efficiency is also high; the irregular shape of the steel sand or steel wire is better than the spherical shot, but the surface roughness is also high.
When selecting the steel pellet size, under the premise of meeting the surface roughness requirement, a larger steel shot is selected as much as possible to improve the cleaning efficiency.
The production process of alloy steel shots is as follows: firstly, high-quality steel blocks, wool yarns and steel scraps are melted, and then molten steel water is poured into water by high-speed centrifugal molding using a centrifugal disk, so that the surface temperature of the steel pellets is drastically lowered to form a pellet. It is a quenching. The quenched pellets are dried and reheated in the furnace to achieve the appropriate hardness. The tempered steel pellets are sorted by mechanical screen into SAE-compliant products of different grades for shot peening. device.
In fact, steel pellets can be reused, and proper recycling can reduce our cost. Steel pellets are not only widely used but also reasonably priced, so they are loved by many manufacturers. It is used in various fields, but many manufacturers have used it once. I thought that the steel pill has been damaged. If it is not used, it will be thrown away. This will cause a lot of waste of resources. In fact, the used steel pill still has value. The used steel pill is treated twice. Still can continue to use.
After many steel mills have used the steel pellets, they think that the sand is broken or the mortar is difficult to handle and it is left blank. Some of them are dumped directly, and a lot of resources are wasted. In fact, the value of the steel shot after use is also quite high, just to deal with the trouble. Sand used after sandblasting and polishing a single steel shot material can be sold back to the manufacturer. After screening and crushing, the manufacturer can obtain small-sized sand. It can also be sold as a weight material to a mechanical weight enterprise or a mortar mixture. After use, it can be sold to chemical companies.
