The main methods of cooling of hot-rolled strip at continuous mills and casting and rolling complexes are considered. Based on the data of the influence of the cooling conditions on mechanical properties of strip, the actuality of the existing equipment and automation modernization is shown (within the boundaries of the runout-table layout). An assessment of the effect of the cooling rate and the placement of water cooling equipment on the microstructure and mechanical characteristics is made. The paper summarizes the research and practical experience of accelerated and intensified water cooling at laboratory equipment and industrial rolling mill. During the production at industrial rolling mill, it has been established that for different thicknesses and initial chemical compositions, it’s possible to increase strength properties and cold-resistance of final strip. The transformation of the microstructure of steel by varying the conditions of post-deformation cooling contributes to obtaining rolled products of various strength classes from steel of the same chemical composition.Keywords: Continuous hot strip mill, hot-rolled steel, intensive cooling, water alloying, mechanical properties
