冷弯型钢是一种经济断面型材。它一般是用热轧或冷轧带钢为原料,在常温状态下,经过拉拔、压弯、折弯或连续辊式弯曲成型,加工成各种断面的型钢。冷弯型钢的生产与使用,具有以下一些特点: 1.可以生产用一般热轧方法难以生产的厚度薄、断面形状复杂的多种规格型材; 2.由于使用冷、热轧带钢为原料,冷 Cold-formed steel is an economic section profile. It is generally made of hot-rolled or cold-rolled strip steel as raw materials, at room temperature, after drawing, bending, bending or continuous roll bending forming, processed into various sections of steel. The production and use of cold-formed steel have the following characteristics: 1. It is possible to produce a variety of profiles with thin thicknesses and complex cross-sectional shapes that are difficult to produce by ordinary hot-rolling methods. 2. As cold- and hot-rolled strips are used as raw materials, cold
