关于彩涂卷支承和变形分析研究

充分整合热轧卷绕全过程的机械设备和加工工艺特点，选择螺旋开口鼓，充分考虑彩涂卷取全过程中沿圆周方向的地应力和变形的不对称性；卷头环与钢丝绳卷筒未完全接触。

提出了一套完整的适用于热扎彩涂和退卷的卷钢内应力分布实体模型，得到了相应的层间滑移分辨率标准， 彩涂卷定制了地应力和层间滑移n型钢气象预报手机软件，并应用于生产实践。
在整个退绕过程中，线圈直径不断扩大。对于某一层彩钢卷，其轴向工作压力增大。对于彩钢线圈的内层，即 彩涂卷引线的头部得到改进，尤其是在相对较大的区域，导致层间粘合的概率不断增加。
然而，对于开卷钢卷，轴向工作压力从内到外、从上到下逐渐减小。然而，周向地应力的规律是不同的，因此其最小值产生在钢卷内部的一层中。随着工作压力的增大，彩涂盘头顶部的周向地应力减小，线圈钢中间的一些层大大减少。如果原始退绕支撑力较大，则会出现负数。

Fuy integrate the mechanical equipment and processing process characteristics of the whole process of hot rolling coiling, select the spiral open mouth drum, fully consider the asymmetry of in-situ stress and deformation along the circumferential direction in the whole process of coiling, and the coil head ring and steel wire rope drum are not completely touched.

Color coated roll
A complete set of solid model of in-situ stress distribution in coil steel suitable for hot tie color coating and unwinding is clearly put forward, the relative interlayer slip resolution standard is obtained, and the weather prediction mobile phone software of in-situ stress and interlayer slip n coil steel is customized and applied to production practice.
In the whole process of unwinding, the coil diameter expands. For a certain layer of color steel coil, its axial working pressure expands. For the inner layer of color steel coil, that is, the leader's head is improved, especially in a relatively large area, resulting in a continuous increase in the probability of bonding between layers.
However, for the uncoiled steel coil, the axial working pressure decreases from inside to outside and from top to bottom. However, the regularity of circumferential in-situ stress is different, so its minimum value is generated in a layer inside the coil steel. The circumferential in-situ stress at the top of the color coated coil head is reduced with the expansion of its working pressure, and some layers in the middle of the coil steel are greatly reduced. If the original unwinding support force is large, there will be a negative number.
