Differential heat treatment of rails by air on the basis of the rolling heat is considered. The research is conducted at AO EVRAZ ZSMK during the reconstruction of rail production. The influence of the chemical composition of the steel and the conditions of plastic deformation and heat treatment on the onset of polymorphic transition is studied. Thermokinetic diagrams are plotted for steels of experimental chemical composition. The cooling rate over the cross section of the rail head is investigated as a function of the heat-treatment parameters. The optimal chemical composition and heat-treatment conditions are determined. The heat treatment of rail samples directly after rolling is experimentally studied. Recommendations for the industrial introduction of differential quenching are developed on the basis of the theoretical and laboratory results. Industrial tests show that the rails produced are of high quality and comply with standard requirements. 相似文献

Multistage heat treatments have been used to clarify transformation mechanisms and to provide a basis for reducing heat treating
time in commercial practice and/or obtaining improved properties. The influence of stepped transformation on the kinetics
of the bainite reaction is examined and the results suggest means for improving the hardenability of medium alloy steels.
The application of double aging treatments to age hardening systems also is examined.
This paper is based on a presentation made at a symposium on Altering the Time Cycle of Heat Treatment, held at the Philadelphia
meeting of The Metallurgical Society of AIME, October 14, 1969, under the sponsorship of the IMD Heat Treatment Committee. 相似文献

Heat stress is an occupational health problem affecting Man in diverse, hostile environments ranging from deep mining to outer space. Healthy, young military recruits and industrial workers exposed to hot, humid environments are typically at risk. The International Classification of Diseases classifies heat disorders into 10 separate entities, of which the most clinically significant are heat cramps, heat exhaustion and heat stroke. The latter is a medical emergency of the first order. Clinical management hinges upon early treatment based on a high index of suspicion. Effective preventive measures and adequate education of those at risk form the basis for its control. 相似文献
