Based on field tests carried out during the manufacturing of high-speed steel rail in Baotou Rail and Beam Plant,effects of heating time and heating temperature on the thickness of decarburized layer of high-speed U71Mn rail are studied.Results show that in normal production,the thickness of the decarburized layer can be effectively decreased with tapping temperature of billets at 1 080~1 100℃ and uniform billet temperature.In the case of rolling delay for 15~30 min,by controlling the temperature of soaking zone and the temperature of sectionⅠof heating zone lower than 1 200℃ and 1 230℃ respectively,the production requirements can be satisfied and the thickness of the decarburized layer reduced.
