Shot blasting is a very common practice nowadays that holds valuable efforts and an astounding result in the industrial application. With every manual work coming under the arena of electronic mechanism, companies are saving extensive time and money on labor intensive work. With the global sand blasting machine market expected to reach USD 441 million by 2020 as per study by Grand View Research, there would be an incremental rise in demand from end user markets including construction, automobile, aerospace and the like.
Ever since shot blasting machines have replaced sandblasting machines in many applications and procedures to annihilate respiratory and related diseases, the shot blasting market is more likely to be impacted by greater demand for this material as a whole.
As we know that blasting is incomplete without media, and of course, shots play a pivotal role in both the performance and result of treatment. India being a big manufacturing giant has many places where engineered products like steel shots are manufactured. Shots are basically used in surface preparation and cleaning applications like removal of loose materials, grease, dirt and rust from surface. They also provide physical modification to a surface.
Shots are important in shot peening applications and the quality of the shots is all the more vital to have an efficient, effective and economical result. Although every shot could be identical in size and shape but the impact of good steel relates to the higher kinetic energy it carries in its strike to successfully produce result oriented compressive stresses on surface.
We must be sure about the quality of the steel shot and check on these following characteristics:
Hardness: The abrasive must be hard enough to not absorb the kinetic energy in its shot or flatten it after a strike against the work surface resulting in slower coverage and lower arc heights. The hardness of shot for shot peening must equate to the hardness of the peened work. Low hardness cannot be compensated by increasing peening cycle. Excessive hardness breaks down shots easily and increase machine running cost.
Microstructure: The structural formation of the shot is to deformation upon impact which gives its tensile strength and cooling like tempered martensite. Carbide mix in shots will fracture them and increase their usage. Chemical analysis will help control hardness and brittle grain formation.
Shape: The shots must not have cracks or shrinkage as it will affect peening. Statistical control methods can monitor the quality of shots being used. High quality media can be purchased from Steel Shots Distributors in India and abroad.
Size: Shot size is crucial to propel shots to correspond to the air compression or the horsepower of the wheel in the machine. Selecting the smallest shot means it absorbs the surface rapidly and give adequate cleaning or shot compression.
Energy: Transmitted energy of the steel shot must be able to be transmitted in its kinetic form to the surface at its fullest. Shots that absorb energy will make the machine run with more cycles to peen and a larger quantity of shots will be required, increasing both time and effort in the process.
As we study the role of shots in shotblasting, the importance of genuine shot sellers is crucial. Quality Spare Centre is the leading Steel shots distributors in Faridabad have been providing export quality shots for both home and abroad. With better steel shots available now, the industry of shot peening is definitely progressing to newer heights every year.
