T字钢属于异形钢材的一种,在形状上可看作H型钢的一半。其断面的特点决定,T字钢可以翻钢轧制,故多用二辊轧机的开口孔型系统进行轧制。随着对T字钢要求的提高(生产腿和腰皆无斜度的产品),出现了多辊孔型轧制法。该法可以对 T-shaped steel is a kind of special-shaped steel, the shape can be seen as half H-beam. The characteristics of the section of the decision, T-beam steel can be rolled over, so the use of two-roll mill open hole system for rolling. With the increase of T-shaped steel requirements (production of products without inclination of the legs and the waist), the emergence of a multi-roll pass rolling method. The law can be right
