Considered the inside and outside contour line was Archimedes spiral in the cold rolling, the forming law of rectangular cross sectional rings has been studied. And the more precise geometrical models and calculation models have been gained. The researches can be used as a theoretical and experimental foundation for the simulation of ring rolling process. At the same time, the results of theoretical analysis have a good agreement with the results of practical rolling production.
本文在考虑冷轧过程中环件的内外轮廓线均为阿基米德螺线的情况下，对矩形截面环件的轧制成形规律进行了研究，得到了较精确的几何模型和计算模型，为环件轧制过程的模拟提供了理论依据和实验依据，同时理论分析的结果与实际轧制生产过程中的结果有较好的吻合。

welded：焊接
不要卖焊接(welded)的和非焊接(unwelded)的吊环螺栓. 你永远也不知道焊得有多好,非焊接的在体重的拉力下就会被拉直了. 只用那些螺纹至少有螺杆一般长度的、锻造的吊环螺栓,光滑的螺杆没法让胶粘住. 9. 对齐吊环螺栓,让环方向垂直.
