| 摘 要： | 在传统理论基础之上,依据微积分原理,采用线性简化模型及定积分方法,深入分析了产品壁厚分布状态,推导得出了管材纵向壁厚控制计算模型,并通过调整定径工序张力改进管体壁厚分布状态,实践结果表明,可有效提高产品成材率1%~3%,且达到了管体壁厚100%合格的控制目标。

| Abstract: | On the basis of traditional theory, in principle of calculus, with method of linear simplifiedmodel and definite integral, the distribution state of pipe wall thickness was deeply analyzed, and thecontrol and calculation model of pipe longitudinal wall-thickness deduced. The distribution state of pipewall thickness was improved by adjusting the tension at sizing mill. Practice results showed this modelcould effectively increase the yield by 1%-3% and reach the control target that 100% pipe wallthicknesswas qualified. |
