Abstract

Изобретение относится к области металлургии, в частности к термической обработке стального изделия, проката различной формы, в т.ч. листового проката, фасонного проката, в частности железнодорожных рельсов. Технический результат достигают способом термической обработки стального изделия, включающим непрерывное и/или дифференцированное охлаждение стального изделия с прокатного и/или повторного нагрева от температуры не ниже температуры аустенизации, при этом охлаждение осуществляют охлаждающей средой, формирующейся в сопловых отверстиях пластины, установленной на выходном отверстии коллектора, путем эжектирования воды потоками газовой среды, которая из системы трубопроводов газовой среды поступает в коллектор и далее в сопловые отверстия пластины, а вода из системы трубопроводов воды поступает в сопловые отверстия пластины по каналам, выполненным в пластине с сопловыми отверстиями. Способ термической обработки стального изделия реализуют благодаря устройству термической обработки стального изделия, содержащему систему трубопроводов газовой среды, систему трубопроводов воды, охлаждающие модули, каждый из которых содержит коллектор с входным отверстием, обеспечивающим ввод газовой среды, выходным отверстием, направленным на термообрабатываемую поверхность стального изделия, на котором установлена пластина с сопловыми отверстиями. В пластине выполнены каналы, по которым вода из системы трубопроводов воды поступает в сопловые отверстия.The invention relates to the field of metallurgy, in particular to the heat treatment of steel products, rolled products of various shapes, including sheet steel, structural shapes, in particular railroad rails. The technical result is achieved by the method of heat treatment of steel products, including continuous and / or differential cooling of steel products with rolling and / or reheating from a temperature not lower than the austenization temperature, while cooling is carried out with a cooling medium formed in the nozzle holes of the plate installed at the outlet of the collector by ejection of water by flows of the gaseous medium, which flows from the piping system of the gaseous medium into the collector and further into the nozzles. Stia plate, and the water from the water pipe system enters the nozzle holes of the plate through the channels formed in the plate with nozzle openings. The method of heat treatment of a steel product is realized thanks to a device for heat treatment of a steel product containing a gas environment piping system, a water piping system, cooling modules, each of which contains a manifold with an inlet opening for introducing a gaseous medium, an outlet opening directed to the heat-treating surface of the steel product, on which is installed a plate with nozzle holes. The plate has channels through which water from the water piping system enters the nozzle openings.
