Steel Shots are spherical in shape, which are produced by the atomization of molten steel, followed by a series of thermal and mechanical treatment in order to attain martensite microstructure. Steel shots are widely used as a media for descaling steel components prior to coating. In this application the media is used almost exclusively in centrifugal wheel airless blasting equipment. It is also used in the foundry casting industry to remove sand from castings after removal from the mould and also for shot peening operations on metal components which are exposed to severe stress in automobile and construction machinery industries
- Removes sand and other surface contamination from steel and iron casting, cast pipes, malleable fittings copper and aluminium alloy castings and other general foundry products.
- Descalling of forged steel products and heat-treated products.
- Shot peening for automotive parts, aircraft components, railway casting, all sorts of gears, super hard steel chips, various tools.
- Used in airless wheel blast machines to clean foundry castings, surface polishing and shot peening.
- Also used in portable trackblast airless wheel blast machines for concrete floor preparation and profiling.
- Long lasting and can be recycled around 100 times, making it the most economical and efficient abrasive.
Steel shot is a non polluting blast media used extensively in the blast cleaning industry to remove paint, rust, millscale and other surface contaminants from steel, concrete and other surfaces prior to coating. It is also used to remove surface contaminations from casting parts in foundry. The cost effectiveness is incomparable due to its impact resistance qualities, durability and with utmost cleaning capacity.
Particle Shape: Rounded abrasive particles produce a peened surface, whereas angular or irregular shaped abrasive particles produced an etched or angular surface profile. Selecting the right particle shape to produce the required profile and texture for the job at hand can impact productivity and performance of the coating applied.
Particle Weight : Different metallic abrasives have different mass weights per unit volume and different impact values. For a given impact velocity and particle shape, the weight (mass) of the particle determines the shape and the depth of the profile produced.
As steel abrasives have approximately 1-1/2 to 2-1/2 times the density of nonmetallic abrasive, steel abrasives create more impact for a given particle size. Smaller steel abrasive particles will produce the same impact value as nonmetallic particles 1-1/2 to 2 1/2 times larger. With the smaller steel abrasive there are more abrasive particles impacting the surface per unit time, which means faster cleaning rates.
Particle Size : Abrasive particle size influences two primary functions of blast cleaning, rate of cleaning and profile. Decreasing particle size may increase cleaning rate because more particles are impacting the surface per unit time. Increasing abrasive size may be necessary to increase profile and/ or to remove heavy coatings.
Particle Hardness : It is generally believed that the harder an abrasive, the better it will perform on difficult to clean areas.
Dust Generation: Metallic abrasives do not break down on impact like conventional nonmetallic abrasive product\\\'s. Consequently, there is considerably less dust and waste generated during the blasting process. Low dust levels mean better visibility, faster cleaning, increased productivity and shorter cleanups, saving time and labor and disposal costs
