The development of rails rolled from continuously cast blooms in the United Kingdom is described. Results of pilot (seven tonne) trials which were begun in 1962 are discussed. These trials evolved into larger scale experiments and eventually into routine processing routes and rail evaluations.
Production experience, mechanical test data, and the results of metallurgical evaluations of rails from the new continuously cast steel process route in various steel grades totalling over 300 000 tonnes are given. Because of the new nature of the process, special testing of the rails was undertaken. These tests included fracture toughness testing and wear tests which compared rails from continuously cast blooms with conventional rails. A program to survey hydrogen content and the development of retarded bloom cooling for shatter crack prevention is reviewed.
