Abstract
Изобретение относится к металлургии, к непрерывной разливке кордовой стали преимущественно с применением машины непрерывного литья заготовок радиального типа. Способ непрерывного литья стали осуществляли на машине непрерывного литья заготовок радиального типа МНЛЗ-3 БМЗ с вертикальным прямолинейным кристаллизатором. Жидкую сталь 1 из сталь ковша подают в кристаллизатор 2 с механизмом осцилляции, в котором в отливке в зоне О формируют твердую корку 3 путем первичного охлаждения стали для образования непрерывно-литой заготовки 4. На выходе из кристаллизатора 2 посредством электромагнитного устройства 5 (ЭМП) производят магнитное перемешивание расплава стали 1 непрерывно-литой заготовки 4 и осуществляют с заданной скоростью радиальную вытяжку непрерывно литой заготовки 4 посредством тянущих роликов 6 с принудительным водяным охлаждением плоскофакельными форсунками 7 в зоне I вторичного водяного охлаждения (ЗВО). За зоной I вторичного водяного охлаждения осуществляют постепенный изгиб и перемещение по дуге непрерывно-литой заготовки 4 с радиусом кривизны 10м. После чего производят перевод непрерывно-литой заготовки 4 в горизонтальное положение. За зоной правки непрерывный слиток разрезают на части-блюмы равной длины. В процессе вытяжки осуществляют скоростной нагрев поверхностных слоев непрерывно-литой заготовки 4 на участке перехода радиальной части дуги МНЛЗ в правильную часть в зоне II воздушного охлаждения.The invention relates to metallurgy, to the continuous casting of cord steel mainly using a continuous casting machine of the radial type. The method of continuous casting of steel was carried out on a continuous casting machine of radial billet type Caster-3 BMZ with a vertical rectilinear crystallizer. Liquid steel 1 from the steel of the ladle is fed to the mold 2 with an oscillation mechanism, in which a solid crust 3 is formed in the casting in zone O by first cooling the steel to form a continuously cast billet 4. At the exit of the mold 2 by means of an electromagnetic device 5 (EMI), Magnetic stirring of the molten steel 1 continuously cast billet 4 and radial drawing of the continuously cast billet 4 is performed at a given speed by means of pulling rollers 6 with forced water cooling with a flat-flare nozzles 7 in the area I of the secondary cooling water (secondary cooling). Behind zone I of the secondary water cooling, gradual bending and movement along the arc of continuously cast billet 4 with a radius of curvature of 10 m is carried out. Then make the translation of the continuously-cast billet 4 in a horizontal position. Behind the straightening zone, the continuous ingot is cut into pieces of equal length. In the process of drawing, high-speed heating of the surface layers of the continuously cast billet 4 is carried out at the section of the transition of the radial part of the caster arc to the correct part in air-cooling zone II.
