角钢的制造工艺比较简单，，生产工艺可分为热轧和冷弯两种，热轧用于大尺寸角钢，冷弯一般是比较小的。 标准工艺是用钢坯（如方坯）经过专用的型钢轧机多道反复轧制逐渐轧成∨形状，材质有保证，在角的内侧有过渡圆弧， 机械性能可靠；而小作坊生产的则是用板材或带钢直接轧（弯）成的，角的内侧没有过渡圆弧， 而且由于是弯曲成的在角处的内应力较大，机械性能较差。不等边角钢的截面高度按不等边角钢的长边宽来计算。 指断面为角形且两边长不相等的钢材。是角钢中的一种。由热轧轧机轧制而成。等边角钢的两个边宽相等。 其规格以边宽×边宽×边厚的毫米数表示。也可用型号表示，型号是边宽的厘米数。型号不表示同一型号中不同边厚的尺寸， 因而在合同等单据上将角钢的边宽、边厚尺寸填写齐全，避免单独用型号表示。 The manufacturing process of Angle steel is relatively simple, the production process can be divided into hot rolling and cold bending two kinds, hot rolling is used for large size Angle steel, cold bending is generally relatively small. The standard process is to use billet (such as billet) through special repeated rolling gradually rolling shape, material guarantee, transition arc in the corners, reliable mechanical performance; and small workshop production is made with plate or strip directly rolling (bending), the corners inside no transition arc, and because of the bending in the corners, poor mechanical performance. The section height of unequal angle steel is calculated according to the long edge width of unequal angle steel. Refto steel with angular section and unequal length on both sides.It is a kind of angle steel.Made from a hot rolling mill. The two sides of the steel are equal width.The specifications are expressed as the number of millimeters wide and wide and thick. It can also be represented by the model, which is a side-wide centimeter number. The model does not indicate the dimensions of different side thickness in the same model, so the side width and side thickness of the corner steel are fully completed in the contract and other documents, to avoid the model alone.
