“控制轧制和控制冷却”是近十多年来国际冶金界十分重视的轧钢生产新技术。在较低的温度下,以强化压下来改善热轧钢材的强度和韧性是控制轧制的基本思想。但是这种低温大变形量的高梯度轧制首先受到轧机轧制能力的限制。 “Controlled Rolling and Controlled Cooling” is a new technology of steel rolling production which has been paid great attention by the international metallurgical industry for more than ten years. At lower temperatures, strengthening the pressure to improve the strength and toughness of hot-rolled steel is the basic idea of ​​controlled rolling. However, this type of high-gradient rolling with a large amount of deformation at a low temperature is first limited by the rolling ability of the rolling mill.
