标题: 热轧三角铁冷轧折弯等边角钢q235b角钢建筑装饰电线塔桥梁
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,最重要的一点是材料没保证,甚至可能是地条钢
这样的角钢买回来一般不能弯曲,也不能焊,最多能取长短钻孔。角钢主要用于制做框架结构,例如高压输电的塔架、
钢结构桥梁主梁两侧的框架、建筑工地上塔式起重机的立柱和臂杆、车间的立柱和梁等,
小的地方如过节路边摆花盆造型的架子、在窗户下挂空调太阳能的架子等。根据其规格和特点,产品分为等边角钢和不等边角钢。
The manufacturing process of corner 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 corner steel,
cold bending is generally relatively small.
The standard process is made of billet (such as billet) through special steel mill repeated rolling gradually rolling shape,
the material is guaranteed, in the corner transition arc, reliable mechanical performance;
while the small workshop is made of plate or strip steel directly rolling (bend), the corner of the transition arc, and is bending in the corner,
poor mechanical performance, the most important point is that the material is not guaranteed, may even be "strip steel",
such corner steel generally can not be bent, welding, can take the length of drilling.Angle steel is mainly used to make frame structures,
such as high-voltage transmission towers, frames on both sides of the main beam of steel structure bridge,
columns and arms of tower cranes on construction sites, workshop columns and beams, etc.,
small places such as festive roadside flowerpot shaped shelves, air conditioning solar shelves under the window, etc.
According to its specifications and characteristics, the product is divided into equal edge corner steel and unequal edge corner steel.
