Magadh can supply 20-hi mills for strip width up to 1625 mm, minimum finish strip thickness up to 0.05 mm and mill speeds up to 800 MPM which are quite popular for rolling high tensile ferrous and non-ferrous metal strips especially of wider width to thinner gauges more effectively than other mill designs.
|
20-hi mills are of mono block housing construction in which the roll separating force is transmitted from the work rolls, through the intermediate rolls to the multiple backup assemblies and finally to the housing (Figure 1). This ensures support of the work roll throughout their length thereby minimizing deflection which facilitates close gauge tolerance across the entire width of the strip.
|
| 20-hi mill is an economical solution for rolling of alloy steels and various grades of Stainless Steels in close gauge tolerance and minimum number of passes. The mill design is compact, screw down is hydraulic and crown control is hydraulic motor/ cylinder actuated. Lateral adjustment is provided at first intermediate rolls while the mill drive is connected through second intermediate rolls. Roll changing is quite simple, foundation costs are reduced and smaller roll grinders are required for grinding of work and intermediate rolls. |
