Using steel shot processing speed and fatigue life
- Nov 13, 2017 -
The hardness of steel shot and cleanup is proportional to the speed, but and is inversely proportional to life.So the higher the hardness of steel shot, clean up the faster speed for a long time, but short life consumption is big, so hard to be moderate (about HRC40-50 advisable) to use the best effect.Choose steel shot with moderate hardness, excellent elasticity of steel shot, every place to clean up the room, also can reduce the processing time.
Steel shot is mainly used to clean up the workpiece, the choice of steel shot and working efficiency is proportional to the correct selection of steel shot is the key to improve the work efficiency, steel shot high hardness, the workpiece cleaning effect is good, relative to the consumption of good, so, the use of steel shot, according to the workpiece material and hardness, to choose the appropriate steel shot, so as to improve the service life of steel shot.
Correct selection of steel shot should pay attention to the following questions;Determine the steel balls mainly depends on the kinds of artifacts, you want pills for aluminum or stainless steel is generally used in nonferrous metals;Ordinary steel, welding, casting, such as the steel will choose steel shot;Steel shot diameter, the greater the cleaned up the surface roughness is higher, but the efficiency is very high;Irregular shape of the steel grit and steel cut wire shot cleaning efficiency than the spherical pellet, but the surface roughness is high;Clean up the high efficiency of the projectile to equipment wear and fast;Just use time to calculate, but production efficiency compared to the wear and tear is not fast.
