Claims (1)

Способ непрерывного литья слитков, включающий подачу металла из промковша в кристаллизатор, вытягивание из него слитка с переменной скоростью, поддержание и направление слитка в зоне вторичного охлаждения с помощью роликов и его комбинированное охлаждение водовоздушной смесью, отличающийся тем, что соотношение сторон кристаллизатора 300·(330-360) мм; температуру стали поддерживают выше температуры ликвидус в промежуточном ковше на 10-30°C, в кристаллизаторе на 0-10°C, скорость вытягивания изменяют в зависимости от температуры стали в пределах 0,60-0,80 м/мин; охлаждение проводят позонно, причем соотношение расхода воды и воздуха (м3/ч) соответственно имеют в первой зоне (1,90-2,15):120, во второй зоне (1,15-1,55):180, в третьей зоне (0,95-1,10):200 при соотношении длин зон охлаждения, мм: 350-1000-1300; а после зоны вторичного охлаждения проводят обжатие непрерывнолитого слитка в тянущих клетях по широкой грани на 2-4 мм.A method of continuous casting of ingots, including supplying metal from a ladle to a mold, pulling an ingot from it at a variable speed, maintaining and guiding the ingot in the secondary cooling zone using rollers, and its combined cooling with a water-air mixture, characterized in that the aspect ratio of the mold is 300 · (330 -360) mm; the steel temperature is maintained above the liquidus temperature in the intermediate ladle by 10-30 ° C, in the mold by 0-10 ° C, the drawing speed is changed, depending on the steel temperature, in the range 0.60-0.80 m / min; cooling is carried out by zone, and the ratio of water and air flow (m 3 / h) respectively have in the first zone (1.90-2.15): 120, in the second zone (1.15-1.55): 180, in the third zone (0.95-1.10): 200 with the ratio of the lengths of the cooling zones, mm: 350-1000-1300; and after the secondary cooling zone, the continuously cast ingot is compressed in the pulling stands over a wide face of 2-4 mm.
