First, hot plate polishing:

Hot plate, the general thickness is more than 3mm, most of the polishing requires about 400 mesh, roughness Ra0.4

1. Abrasive belt polishing:

Optional belt size: width 60 mm length 2000mm Price: 29-35 yuan (40#-400# abrasive belt) hot plate polishing belt use order: 60#, 80#, 120#, 240#, 400#,60#, 80# is a ceramic abrasive belt used for polishing stainless steel surface oxide scale. It is coarsely polished and has a large amount of grinding. It is also suitable for polishing pressure vessel welds (the weld is relatively hard).

Rough throwing (60#, 80#) an abrasive belt can be polished to an area of about 10m2, and the belt consumption is about 2.9 yuan ∕m2 fine throwing (120#, 240#, 400#) for the stacked abrasive belt. Medium, fine polishing, small amount of grinding, more wear-resistant,

The abrasive belt can be polished to an area of about 20m2, and the belt consumption is about: 1.8 yuan ∕m2

Under normal circumstances, the polishing of stainless steel plates of 3mm or more is required to reach a roughness of Ra0.4. According to the above method, the coarse throwing and fine polishing are performed using 40#, 80#, 120#, 240#, 400# abrasive belts, and the total cost of polishing 5 times is 8.3.RMB∕m2

2. Thousand impeller polishing:

Optional thousand impeller size: diameter 250mm, thickness 35mm Price: 30-40 yuan

The order of hot plate polishing thousand impellers is: 60#, 80#, 120#, 240#,400#,60#, 80#, thousand impellers are used for polishing stainless steel surface oxide scale, which is coarsely polished, with large grinding amount and no wear resistance.

A thousand impeller can be polished to an area of approximately 18m2, and the thousand impeller consumption is approximately: 1.67 yuan ∕m2

120#, 240#, 400#, thousand impellers, used for medium and fine polishing, with less grinding and wear resistance.

A thousand impeller can be polished to a surface area of approximately 28 m2, and the thousand impeller consumption is approximately: 1.43 yuan ∕ m2

Under normal circumstances, the polishing of stainless steel plates of 3mm or more is required to reach a roughness of Ra0.4. According to the above method, the coarse throwing and fine polishing are performed using 40#, 80#, 120#, 240#, 400# abrasive belts, and the total cost of polishing 5 times is 7.39.RMB∕m2
