河北关于建筑工业彩涂卷支承和变形分析研究「下」

河北建筑工业彩涂卷充分结合热轧卷取全过程的机械设备和加工工艺特点,选用螺旋开口筒式方式,充分考虑放卷全过程中地应力和变形沿圆周分布的不均匀性,线圈头线圈与钢丝绳卷筒未完全接触。

提出了一套适用于热浸彩涂退卷的钢卷内部地应力的实体模型,得出了层间滑移的相对分辨率标准,开发了钢卷相对地应力和层间滑移天气河北建筑工业彩涂卷预报手机软件,并应用于生产实践。
河北建筑工业彩涂卷在整个退卷过程中,卷径都会扩大。对于某一层彩钢板卷,其轴向工作压力会增大。对于彩涂线圈的内层,也就是领头羊带头改进,特别是在面积比较大的情况下,这样层间结合的概率会继续上升。
但是,轴向工作压力从内到外、从上到下逐渐减小。但环向地应力的变化规律不同,其最小值是在钢卷内部某一层产生的。彩涂卷头顶部的周向地应力随工作压力的增大而减小。钢卷中间的一些层大大减少。如果原始放卷支撑力较大,则会出现负数。

Fully integrate the characteristics of the machine equipment and processing technology in the whole process of hot rolling coiling, select the spiral opening barrel type mode, fully consider the uneven distribution of ground stress and deformation along the circumference in the whole process of unwinding, and that the coil head coil and the wire rope drum are not completely contacted.

Color coated roll
A set of solid model of in-situ stress in coil steel suitable for hot-dip color coating and unwinding is put forward, and the relative resolution standard of interlayer slip is obtained, and the mobile phone software for weather prediction of relative in-situ stress and interlayer slip of coil steel is developed and applied to production practice.
In the whole process of unwinding, the coil diameter will be expanded. For a certain layer of color steel coil, its axial working pressure will be enlarged. For the inner layer of color coated coil, that is, the leader takes the lead to improve, especially in a relatively large area, so that the probability of interlayer bonding will continue to rise.
However, the axial working pressure decreases from inside to outside and from top to bottom. However, the regularity of circumferential geostress is different, and its minimum value is generated in a certain layer inside the coil steel. The circumferential geostress at the top of the color coated coil head decreases with the increase of its working pressure. 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.
