Abstract

FIELD: petroleum industry machine engineering. SUBSTANCE: method involves rapid heating up to temperature higher than Ac3, holding and air cooling only those ends of rod and adjacent portions upset and preliminarily cooled after upsetting operation up to temperature lower than 700 C. After thermal treatment for martensite type steels, additional high-temperature tempering is conducted with heating up to 500-700 C with air cooling. EFFECT: increased endurance limit of heads and adjacent to them portions of rod body and therefore the structure of rod as a whole.

После предложенной термической обработки для сталей мартенситного класса осуществляют дополнительно высокий отпуск с нагревом до 500-700°C и охлаждением на воздухе. Данная технология позволяет повысить предел выносливости головок и прилегающих к ним частей тела штанги, а следовательно и штанги как конструкции в целом.After the proposed heat treatment for martensitic steels, an additionally high tempering is carried out with heating to 500-700 ° C and cooling in air. This technology allows you to increase the endurance limit of the heads and adjacent parts of the body of the rod, and therefore the rod as a structure as a whole.
