Title: Method of finishing stainless steel coils and sheets.

Summary:

The use of non-woven abrasive belts on belt machines, producing a brushed finish on stainless steel equivalent to that currently obtained by the use of abrasive brushes on brush machines.

Description:

Stainless steel with various pre-finished surfaces is supplied to the metal fabrication market by coil manufacturers or by service centers.

Currently, the surface is either sanded with a coated abrasive belt, grit 240 or 220 being the last step, or brushed with non-woven abrasive brushes.

There are several advantages in achieving the brushed finish with non-woven abrasive belts:

1. The productivity of the finishing lines can be significantly increased, as brushes work well up to 10 metres per minute line speed, whereas belts can perform up to 40 metres per minute line speed.

2. Maintenance costs are decreased. Changing a brush takes several hours and can require two operators. If this change operation is not done during scheduled maintenance periods, the line must be stopped. Belts can be changed without stopping the line, in a few seconds, by one operator.

3. From the surface finish point of view, brushes must be accurately manufactured and well balanced to avoid any finish defects. Belts produce uniform finishes with simple technology.

4. Logistics and storage is less a problem with belts, compared to brushes.

5. Investment in machinery is minimized. Non-woven belts can be mounted on existing belt machines...
