Original Abstract

An in-line heat treatment of rolled materials is becoming frequently used by hot rolling plants. This method achieves the required material structure without the necessity of reheating. This paper describes a design procedure of cooling sections for obtaining the demanded structure and mechanical properties. An experimental stand, applied for the cooling study of steel samples, was built at the Brno University of Technology. The stand carries a movable trolley with a tested sample. The sample moves under the spray by a given velocity. The sensors indicate the temperature history of the tested material. This experimental stand enables to simulate a variety of cooling regimes and evaluate the final structure of the tested samples. The same experimental stand is a tool for the design of the cooling sections which can ensure obtaining demanded heat treatment procedure and demanded final structure. The HTC history at the surface is reached as an output of inverse task. Cooling examples of rails and tubes are presented in the paper.
