Brand steel shot selection, secondary quenching of scrap steel with high requirements, high-quality Anlan brand

Description :

　　The hardness of steel shot is directly proportional to its consumption. Those engaged in the abrasive industry know that as the hardness of steel sand increases, the speed of cleaning the workpiece becomes very fast. However, the corresponding consumption of steel shot also becomes very fast, and its service life will be shortened faster than usual. So generally, from the perspective of economic benefits, steel grit with moderate hardness is selected for processing before cleaning the workpiece.

　　Another possibility is that you purchased recycled or non-standard steel pellets, which do not meet the quality standards and are prone to breakage. In addition, the larger the diameter of the steel shot, the higher the surface roughness after cleaning, but the cleaning efficiency is also high; The cleaning efficiency of irregularly shaped steel grit or steel wire cutting pellets is higher than that of spherical pellets, but the surface roughness is also higher; Bullets with high cleaning efficiency also wear out equipment quickly (relatively), only in terms of usage time, but compared to production efficiency, this wear is not considered fast.

　　Customers who use shot blasting machines all want to find suitable steel shot. High quality steel shot can effectively protect shot blasting machine equipment, improve the service life of shot blasting machine parts, and reduce the maintenance cost of shot blasting machines. Based on the experience of Anlandi Steel Ball Editor, the selection of commonly used steel balls for different workpieces is summarized below for reference only:

　　1. Non ferrous metals generally use aluminum or stainless steel pellets;

　　2. Use steel balls for ordinary steel and its welded parts, castings, steel, etc;

　　What are the effects of steel shot hardness, steel shot shell, and steel shot density on the service life of steel shot?

　　a)、 Hardness is directly proportional to cleaning speed, but inversely proportional to lifespan. So the hardness is high, the cleaning speed is fast, but the service life is short and the consumption is large, so the hardness should be moderate (about HRC40-50 is suitable) and the use effect is good.

　　b)、 Moderate hardness and excellent rebound enable the steel shot to reach every part of the cleaning chamber, reducing processing time.

　　c)、 Internal defects such as porosity, cracking, and shrinkage porosity in projectile materials can affect their lifespan and increase consumption.

　　d)、 If the density is greater than 7.4g/cc, the internal defects tend to be minimized.
