Abstract

THE CONVENTIONAL HOT STRIP MILL (HSM) IS REGARDED AS THE MOST VERSATILE AND FLEXIBLE METALLURGICAL TOOL FOR THE PRODUCTION OF HOT ROLLED COILS, BOTH IN TERMS OF PRODUCT DIMENSIONS AND STEEL GRADES. DUE TO THE PROCESS CHARACTERISTICS OF THE HSM, THERE ARE PARTICULAR CHALLENGES WHEN IT COMES TO THE PRODUCTION OF THIN-GAUGE HOT ROLLED STRIP. THIS APPLIES FOR BOTH, SOFT CARBON STEEL GRADES, AS WELL AS, DRIVEN BY THE MARKET REQUIREMENTS, INCREASINGLY ALSO FOR HIGH-STRENGTH STEEL GRADES. SMS GROUP HAS DEVELOPED A COMPREHENSIVE “TOOL BOX” IN ORDER TO SUPPORT THE STABLE AND EFFICIENT PRODUCTION OF “THIN” HOT STRIP IN A CONVENTIONAL HOT STRIP MILL. THE “TOOLBOX” CONSISTS OF MECHANICAL PACKAGES AND AUTOMATION PACKAGES WHICH WILL BE INTRODUCED IN THIS PAPER. IN ADDITION, PRACTICAL RESULTS FROM EXISTING HSMS WILL BE PRESENTED.
