Abstract
Изобретение относитс к области металлургии и может быть использовано при производстве булатной стали. Цель - повышение качества стали за счет предотвращени образовани трещин и получени булатного узора. В тигель индукционной печи загружают лом углеродистых сталей. После расплавлени металл науглероживают графитом до содержани углерода 1,6% и нагревают до 1530°С. Сталь разливают в цилиндрические слитки диаметром 160 мм и высотой 160 мм, которые охлаждают до 900 - 1000°С со скоростью 15 - 80 град/мин, а по достижении этой температуры - со скоростью 200 - 300 град/миин. После охлаждени слитки куют при 630 - 850°С. Способ позвол ет получить качественные слитки с булатным узором и без трещин. 1 табл.The invention relates to the field of metallurgy and can be used in the production of damask steel. The goal is to improve the quality of the steel by preventing the formation of cracks and obtaining a damask pattern. Carbon steel scrap is loaded into the crucible of the induction furnace. After melting, the metal is carbonized with graphite to a carbon content of 1.6% and heated to 1530 ° C. The steel is poured into cylindrical ingots with a diameter of 160 mm and a height of 160 mm, which are cooled to 900–1000 ° C at a speed of 15–80 deg / min, and, when this temperature is reached, at a speed of 200–300 deg / min. After cooling, the ingots are forged at 630-850 ° C. The method allows to obtain high-quality ingots with damask pattern and without cracks. 1 tab.

Изобретение относитс к области металлургии и может быть использовано при производстве булатной стали.The invention relates to the field of metallurgy and can be used in the production of damask steel.
Цель изобретени - повышение качества стали за счет предотвращени образовани трещин и получени булатного узора.The purpose of the invention is to improve the quality of steel by preventing the formation of cracks and obtaining a damask pattern.
П р и м е р. В тигель индукционной печи загружают 12 кг лома углеродистых сталей. После расплавлени металл науглероживают графитом до содержани углерода 1,6% и нагревают до 1530°С.PRI me R. In the crucible induction furnace load 12 kg of scrap carbon steel. After melting, the metal is carbonized with graphite to a carbon content of 1.6% and heated to 1530 ° C.
Полученную сталь разливают в цилиндрические слитки диаметром 160 мм и высотой 160 мм. Изменение температуры показывает, что такие слитки можно охлаждать так, что в центральных зонах обеспечиваетс скорость охлаждени 15-20 град/мин, а на поверхности 50-80 град/мин. После достижени на поверхности слитка температуры 1000-900°С он охлаждаетс со скоростью 200-300 град/мин (на поверхности).The resulting steel is poured into cylindrical ingots with a diameter of 160 mm and a height of 160 mm. The change in temperature shows that such ingots can be cooled so that in the central zones a cooling rate of 15-20 degrees / min is provided, and on the surface 50-80 degrees / min. After the temperature of the ingot reaches 1000-900 ° C, it is cooled at a speed of 200-300 degrees / min (at the surface).
После охлаждени слитки нагревают до 630-850°С и куют в разных направлени х. Поковки имеют булатный узор, равномерно распределенный на поверхности.After cooling, the ingots are heated to 630-850 ° C and forged in different directions. Forgings have damask pattern, evenly distributed on the surface.
В таблице приведены данные по результатам реализации способа.The table shows the data on the results of the implementation of the method.
В случае известного способа булатный узел выражен слабо и, кроме того, в слитках наблюдаютс трещины.In the case of the known method, the damask knot is weakly expressed and, moreover, cracks are observed in the ingots.
