Final report on Contract No 7210-PA/014; 1 July 1997 to 31 December

The project has examined the formation of scale during direct casting of steel strip in a collaboration of MPI, IRSID, TKS and Corus UK. Scale grown in casting under air and the corresponding yield losses have been evaluated. Systems to prevent oxygen access to the strip surface have been developed ranging from cassette shrouds on pilot casting machines to a fully enclosed laboratory caster. The effect of reduced oxygen partial pressures was investigated by off-line tests. Steel grades were low carbon, high carbon and silicon steels, also with aluminium addition. Theoretical modelling has been developed and validated which allows prediction of scale thickness on the basis of thermal computations and kinetic expressions. The effect of meniscus protection by non-oxidising gases was studied. Pickling behaviour was investigated as a function of the pickling solution and steel grade and direct descaling by solid carbon dioxide under high pressure was tested.
