Abstract

This is to present at three examples the scope of work, the targets and the results. 1. Revamp of the HSM Salzgitter/Germany. Scope:Slab Sizing Press, new 4-high roughing mill stand with attached edger, new loopers, shifting and bending systems at the finishing mill, complete L1 + L2. Target: Quality improvement, capability to roll new high demanding steel grades. 2. Revamp of the HSM Meishan/China in two steps Scope Step 1: Heat retention hoods, new descaler; AGC-cylinders F4-F6, shifting/bending F1-F6, new looper, new spindles, new runout roller tables with new laminar cooling, new downcoiler Target Step 1: Increase of produvrion from 1,2 to 1,75 Mio tpa Scope Step 2: new roughing mill with edger, two new descaler, new F0 infront of finishing train, installation of coilbox Target Step 2: Increase of production to 3 Mio tpa. 3. Revamp of the Steckel-Mill Outukumpo Stainless/Finland. Scope: 3 finishing mill stands behind the existing Steckel-mill stand, second downcoiler, L2. Target: Double of production to 1,65 Mio tpa; improve of quality
