The future of cooling - process industry examples - Name: Klaus Peters Position: Secretary General Entity: ESTEP – European Steel Technology Platform

cooling in steel industry 1 In the steel industry cooling is used to achieve special properties in modern steels. 2 The production of steel is linked to high temperature treatment. The reactors and the equipment have to be cooled. Water cooling Air cooling New cooling 2

Life Cycle of Water 3 Source: worldsteel.org

High water demand low water consumption 4

Continuous Casting of Steel precise temperature Air-water-cooling (2-phase) Precise mild Technical data Slabs 1.000 <w<2.150 mm t < 257 mm 2 strang arc-typ caster 80t tundish (distributor) Cooling of the hot strang Single nozzle on/off modus Zone cooling over width Less edge defects at slabs Important for high strebgth steels 5

New cooling medium in annealling processes Higher heat flux Production of modern high strength steels (quenching & partinioning) 6 Source: Research Fund for Coal and Steel (RFCS)
