Abstract

Изобретение относится к области черной металлургии, в частности к способам и устройствам термической обработки железнодорожных рельсов. Техническим результатом является универсальность способа и устройства, которые позволяют осуществлять термическую обработку рельсов как из углеродистых нелегированных сталей, так и из легированных сталей. Способ позволяет производить охлаждение рельсов со скоростями охлаждения в пределах 2-20°С/с, плавно изменять скорости охлаждения в процессе термообработки, получать однородную мелкодисперсную перлитную структуру (сорбит закалки) на глубину более 22 мм от поверхности и получать твердость по поверхности катания до НВ401. Регулирование охлаждающей способности газовой среды производят по программно заданному режиму путем импульсной квазинепрерывной и/или непрерывной инжекции воды в поток воздуха. В зависимости от химического состава рельсовой стали и начальной температуры рельса не ниже температуры аустенизации регулируют расход газовой среды от 20 до 60 м/мин на 1 метр погонный рельса, при этом расход инжектируемой воды составляет до 12 л/мин на 1 метр погонный рельса. Кроме того, содержание воды в газовой среде составляет до 0,2 л воды на 1 мвоздуха. Давление газовой среды регулируют в пределах от 0,005 до 0,1 МПа.The invention relates to the field of ferrous metallurgy, in particular to methods and devices for heat treatment of railway rails. The technical result is the versatility of the method and device, which allow heat treatment of rails from carbon unalloyed steels and alloy steels. The method allows cooling the rails with cooling rates in the range of 2-20 ° C / s, smoothly changing the cooling speeds during the heat treatment, to obtain a homogeneous finely dispersed pearlite structure (quenching sorbitol) to a depth of more than 22 mm from the surface and to obtain hardness along the rolling surface to HB401 . The cooling ability of the gaseous medium is regulated according to the programmed mode by means of a pulsed quasi-continuous and / or continuous injection of water into the air stream. Depending on the chemical composition of the rail steel and the initial rail temperature not lower than the austenization temperature, the gas flow rate is controlled from 20 to 60 m / min per 1 meter of running rail, while the flow of injected water is up to 12 l / min per 1 meter of running rail. In addition, the water content in the gas medium is up to 0.2 liters of water per 1 air. The pressure of the gas medium is regulated in the range from 0.005 to 0.1 MPa.
