1.Stainless Steel AISI 316-L or LDX2101
2.The normal sheet thickness is 3,00 – 3,25 mm for steel and titanium, which thickness tolerance is (+0.04mm, -0.12mm).This is the optimum thickness taking into consideration the plate performance, ease of manufacture and cost-effectiveness
3.V-groove and lifting ears are usually machined to the sheet
Cathode Sheet: Stainless Steel AISI 316-L or LDX2101
Cathode plate the bottom corners have square notches of steel
removed. And it has 45 degrees chamfered corners cut away from the
bottom of the blade. The dimensions of the chamfered corners are 60mm x 60mm. These
dimensions have been chosen to maximise the tearing action, whilst reducing the
chances of bending the cathode corners or producing a ropey edge that would
potentially entrap falling slimes. The tearing action produced by the corner chamfers
initiates the split of the copper sheets and improves splitting if lamination has
occurred. Now these corners vary shapes and sizes. Smaller corner cut outs as well as rounded corners were trialled.
Cathode sheet is 3.25 mm thick. This is the optimum
thickness taking into consideration the plate performance, ease of manufacture and
Tolerance as follows,
Flatness tolerance: 2.0mm when sheet is hung from top edge.
Camber tolerance: 1.0mm.
Parallel tolerance: 1.0mm wide, datum opposite edge.
Squareness tolerance: diagonal dimensions to be within 1.5mm of each side.
Sheet finish: both sides 2B cold-rolled and annealed.
Surface roughness: 0.25 to 0.60 Ra in accordance within ISO/R1302, sheet to be free from burrs and sharp edges.
0.2% proof strength(yield) of the material shall be less than 310 Mpa
