Abstract
Винахід належить до галузі чорної металургії, а саме - до способу термічної обробки інструменту з середньолегованої сталі. Спосіб полягає у попередньому підігріванні, подальшому нагріванні до температури гартування, витримці, гартуванні у рідкому гартівному середовищі, відпусканні, причому гартування проводять у рідкому гартівному середовищі до температури поверхні інструменту Мк - Мк - 50 °С, де Мк - температура закінчення перетворення аустеніту в мартенсит в сталі, з якої виготовлено інструмент, а після відпускання виконують охолодження інструменту у воді до закінчення її кипіння. Винахід забезпечує зменшення часу на термічну обробку та підвищення стійкості термообробленого сталевого інструменту.The invention relates to the field of ferrous metallurgy, namely to a method of heat treatment of a tool of alloy steel. The method consists in pre-heating, subsequent heating to the tempering temperature, holding, tempering in a liquid quenching medium, tempering, and the quenching is carried out in a liquid quenching medium to the surface temperature of the tool Mk - Mk - 50 ° C, where Mk - the temperature of the end of the transformation of the austen in steel from which the tool is made, and after release, the tool is cooled in water until its boiling is complete. EFFECT: invention reduces the time for heat treatment and increases the stability of the heat-treated steel tool.
