Из-ве стен способ обработки труб из малоуглеродистой низколегирОВаннон стали, включающий лн-югократную холодную деформацию, промежуточную терм ическую обработку и высокий отнуск после деформачит на .копечный размер.Because of the walls, there is a method of processing pipes from low-carbon low-alloy steel, which includes cold cold deformation, intermediate thermal treatment and high recovery after deforming into a large size.
С целью повышени нрочиости труб предлагаетс перед дефорлшцией на конечный размер подвергать их иормализацин.In order to increase the pipelines, it is proposed to subject them to normalization before deforming to the final size.
Этот способ обработки, на-прнмер труб 16X2,5 мм т стали 12Х1МФ, включает холодную нрокатку заготовки 57X6,5 мм иа размер 42x3,5 мм, высокий отнуск, химическую обработку, холодиую прокатку на размер 22X2,4 мм, нормализацию, химическую обработку , безонравоч иое волочение на конечный размер 16X2,5 мм, высокий отпуск н хи-мическую обработку. В результате нормализации труб неред деформацией на коиечиый размер и последующего отнуска ироисходит nepeipacпределение карбидной фазы, обеспечивающее новышение нрочиостных характеристик нри соxpaiiciiiiii и,1астическ х.This method of processing, on-prnmer pipes 16X2.5 mm t steel 12H1MF, includes cold rolling rollers of the workpiece 57X6.5 mm and size 42x3.5 mm, high recovery, chemical treatment, cold rolling for size 22X2.4 mm, normalization, chemical treatment , no-drag drawing for a final size of 16X2.5 mm, high tempering and chemical treatment. As a result of pipe normalization by non-deformation at a coic size and subsequent depletion, the carbide phase is determined nepeipac, which provides an increase in the physical characteristics of the cohpiciciiiiii and partly.
Предлагаемый способ был опробован нрп производстве труб из стали 12Х1МФ. По сравнению с известным способом предел прочности 5 груб повысилс .на 20-25%, предел текучест 1 - па 60% при со.храиении пластических свойств.The proposed method was tested by the NPP production of pipes from steel 12H1MF. Compared with the known method, the tensile strength of 5 is roughly increased by 20-25%, the yield strength of 1 is 60% for the case of plastic properties.
Благодар иовышеппю прочиости труб, применение опИсываемого способа позвол ет соQ кратить расход металла при производстве трубиых конструкций.Thanks to the high pipe strength, the use of the method described allows you to reduce the consumption of metal in the production of pipe structures.
