Power Cooling And Mulpic Technology For Hot Rolled Flat And Plate Production

The market trend of advanced high strength steel (AHSS) with demand for higher strength products is increasing continuously. The inline cooling technologies have established as the most powerful metallurgical tool to achieve these demands. However, the cooling capabilities of existing hot strip mills, plate and Steckel mills are often not adequate to generate high cooling rates and the cooling accuracy required for the production of AHSS. Hence there have been many developments for an intensive, highly flexible accurate homogeneous cooling technology. Considering the wide variety of strip and plate geometry, Primetals Technologies have developed Power Cooling Technology for strip and introduced MULPIC®4 Technology for the plate production. In this paper we shall discuss these enhanced technologies that provide the inline cooling requirement with examples from the recently commissioned machines.
