彩钢卷的受力状态怎么样

彩钢卷的受力状态怎么样


彩钢卷的压力如何
彩钢卷在滑动摩擦损伤作用下,带状带的比拉伸强度小于带状力F0。带状带的最终抗拉强度与带状带与彩钢卷或墙角的摩擦阻力有关。彩钢卷可通过降低彩钢卷与彩钢卷或墙角的摩擦阻力(如加润滑脂)来提高捆扎带的捆扎效果。
在彩钢卷绑扎的整个过程中,当扣在卷内孔时,彩钢卷内外层的压力不平衡,并有沿径向相对运动的趋势;当扣在彩钢卷中心时,彩钢卷的压力是对称的,比扣在彩钢卷端面的压力要好。卷取成形的关键是热轧卷和冷轧卷。热轧钢卷是板坯淬火前的一种生产加工商品。冷轧钢卷是热轧钢卷的后生产加工。

彩钢卷一般净重上下15-30t。2019年以来,我国热连轧生产制造能力持续扩大。目前已有数十条热轧带钢生产线,并将新建或生产一些项目。
彩钢卷销售的关键是面向大客户。一般来说,客户没有放卷机的机器和设备或使用受到限制。因此,彩钢卷的后生产加工将是一条很有前途的产业链。或许,在现阶段,大型炼钢厂往往有自己的退卷和整平新项目。


How about the pressure of color steel coil

Beuse of the damage of sliding friction, the specific tensile strength of the banding belt is lower than that of the banding force F0. The final tensile strength of the banding belt is related to the friction resistance between the banding belt and the color steel coil or the wall corner. The color steel coil can improve the binding effect of the banding belt according to reducing the friction resistance between the banding belt and the color steel coil or the wall corner (such as adding grease).
In the whole process of binding the colored steel coil, when the buckle is in the inner hole of the coil, the pressure of the outer and inner layers of the colored steel coil is unbalanced, and there is a trend of relative movement along the radial direction; when the buckle is in the center of the colored steel coil, the pressure of the colored steel coil is symmetrical, which is better than that when the buckle is on the end surface of the colored steel coil. The key of forming coil is hot rolling coil and cold rolling coil. Hot rolled coil is a kind of production and processing commodity before slab hardening. Cold coil is the post production and processing of hot rolled coil.
Color steel coil
The general net weight of color steel coil is 15-30t up and down. Since 2019, the production capacity of hot strip production and manufacturing in China has continued to expand. There have been dozens of hot strip production lines, and some new projects will be built or produced.
The key to the sale of color steel coil is for big customers. Generally, customers do not have the machine and equipment of the unwinder or the usage is limited. Therefore, the post production and processing of color steel coil will be a promising industrial chain. Perhaps, at this stage, the larger steelmaking plants often have their own unwinder and leveling new projects.
