Accelerated Cooling After Controlled Rolling During Heavy Plate Pipe Steel Manufacture in 3600 Mill at the Azovstal Metallurgical Combine

Contemporary controlled rolling technology with accelerated cooling is assimilated at the Azovstal Metallurgical Combine, used in production of plate intended for manufacturing gas and oil pipelines of considerable diameter. General characteristics are provided for the SMS-Demag accelerated controlled cooling unit in the plate workshop within the 3600 mill line. Mechanical properties are tested and the microstructure is examined. Batches of pipe steels of various grades satisfy test specifications and are estimated as favorable according to results for pipes manufactured from them.
