Shipbuilders and manufacturers of large machinery, bridge components and pressure vessels and tanks often order plate that has been shot blasted to remove mill scale and rust, then primed to prevent rusting during shipment and processing. This clean plate product not only alleviates users from having to perform post-processing cleaning and priming themselves, but it keeps their fabrication shops much cleaner and healthier.
EPS Cell Configuration version 5.2 has been developed to serve the growing need for large, clean plate. It utilizes EPS Slurry Blast technology, in a configuration different from other EPS Cell designs, to descale plate from 1800 mm to 4100 mm (71″ to 160″) wide and 8 mm to 100 mm (0.315″ to 4″) thick. Length is limited only by the conveying system used to transport the plate through the Version 5.2 Cell.
The image below shows how Cell Version 5.2 operates. Rather than feeding the plate lying flat as is done with coil, the plate is stood up on its side with the 8 Slurry Turbines (4 per side) arrayed vertically to cover the width of the plate. (Note that for processing of more narrow plate, the top turbines are shut off). This makes for a simple, compact cell design.
But rather than being just a replacement for shot blasting, Version 5.2 offers the inherent advantages Slurry Blasting has over shot blasting:
- More complete, consistent scale removal.
- No inclusions that entrap dust, oil or contaminants to the surface. A much cleaner surface overall.
- A surface finish that is optimized for paint performance.
In summary, while plate suppliers have increased their value added by providing a shot blasted & primed product, they can offer an even better product by using EPS Cell version 5.2 technology. In doing so, they would also find that an EPS processing line runs cleaner and more efficiently than a conventional shot blasting line.
