EXPERIENCE OF AIR-JET THERMAL TREATMENT OF THE HEAD OF E76F RAILWAY ROLLS USING HEAT FROM ROLLS
Abstract
Heat treatment of railway rails, along with the chemical composition of the steel, is the most effective means of improving their performance properties. The introduction of oil quenching of rails using furnace heating in the late 1970s, first at the Nizhny Tagil and then at the Novokuznetsk Metallurgical Plants, nearly doubled their operational life, propelling domestic manufacturers to the forefront of this technology at the time, and the rails produced were among the best in the world. In addition to oil quenching, water, air-water mixtures, and polymer and salt solutions are used for thermal strengthening of rails. Heat treatment is carried out using rolling or special heating (furnace or high-frequency heating).
