关于山东10个厚彩钢板屋面彩涂卷支承和变形分析研究「上」

以下文章的内容将着重对10个厚彩钢板屋面彩涂卷的支撑和变形进行详细的论述。彩涂辊的产品质量不仅取决于板材和建筑涂料的基本特性,还取决于生产工艺和实际操作控制系统。

10个厚彩钢板屋面彩涂卷控制系统的实际运行对彩涂产品的工艺性能有很大的负面影响。从生产过程分析,生产制造控制系统的首要任务应包括四个阶段:清洗、化学涂层、喷涂和干燥。现在让我们来了解一下彩涂辊的支撑和变形的研究。
10个厚彩钢板屋面彩涂卷在退卷过程中的热应力计算是基于微分方程的计算,将卷取为延性薄壁管或延性构件筒体。
事实上,彩涂辊通常薄而厚,且彩涂辊沿圆周具有明显的非圆特性。根据圆辊的计算,如果圆辊的计算误差很大。
因此,在热轧彩涂卷退卷的整个过程中,内带钢沿周向的非圆特性对带钢厚度的提升更为明显。以往的环向对称闭桶模型不仅与带材的实际情况存在较大误差,而且不能准确分析层间滑动问题。

The content of the following article will focus on the support and deformation of the color coated roll in detail. The product quality of the color coated roll not only depends on the basic characteristics of the plate and architectural coating, but also depends on the production process and the actual operation control system.

The actual operation of the control system has a great negative impact on the process performance of color coated products. From the production process analysis, the top priority of the production and manufacturing control system should include four stages: cleaning, chemical coating, spraying and drying. Now let's learn about the research of the support and deformation of the color coated roll.
The calculation of the thermal stress of coil steel during the unwinding process of color coated coil is based on the calculation of differential equation by taking the coil as a ductile thin-walled tube or a ductile component cylinder.
In fact, the color coated roll is usually thin and thick, and the color coated roll has obvious non-circular characteristics along the circumference. If the color coated roll is solved according to the circular curve, the calculation error will be very large.
Therefore, the non-circular characteristics of the inner strip along the circumferential direction are more obvious for the lifting of the strip thickness in the whole process of hot tie color coated coil unwinding. In the past, the closed barrel model with circumferential symmetry not only has a great error with the actual situation of the strip, but also can not accurately analyze the problem of sliding between layers.
