中文摘要：

研究了不同压下规程、不同工作辊直径以及不同轧件强度对同步轧制最小可轧厚度的影响并得到在不同条件下的轧件最小可轧厚度。结果表明：同步轧制中轧件的最小可轧厚度与压下规程无关,而与轧辊直径成正比,与轧件的平面变形抗力成正比;在工作辊直径分别为180、120、50 mm的轧机上,Q195轧件的最小可轧厚度分别为139、94、40μm。在工作辊直径为50 mm的轧机上,Q195、硅钢、工业纯铝的最小可轧厚度分别为40、60、8μm。

英文摘要：

The effects of different reduction schedules, different work roller diameters and different rolled piece strength on the permissive thickness in symmetrical rolling were investigated. And the permissive thickness of rolled piece was obtained under different rolling conditions. The results show that the permissive thickness has nothing to do with reduction schedule in symmetrical rolling. The permissive thickness is proportional to the diameter of roller and is proportional to the plane deformation resistance. The permissive thickness of Q195 rolled piece in work roller diameters of 180,120, and 50 mm rolling mill is 139, 94 and 40 μm, respectively. The permissive thickness of Q195, silicon steel and commercially pure aluminium in work roller diameter of 50 mm rolling mill is 40, 60 and 8 μm, respectively.
