AN EXPERIMENTAL INVESTIGATION ON ROLLING LOAD IN CROSS SHEAR COLD-ROLLING FOR ULTRA-THIN STRIPS

Lin Dawei Pan Dawei Zhu Quan  
With a mismatched roll-speed ratio,the ultra-thin strips of steel and copper had been successfully cold-rolled on φ90/φ200×200mm 4-high mill by a research group led by Zhu Quan in 1979.Strips were reduced even to a thickness of 0.005mm or a ratio D/h0 of about 18,000.In order to practically put the new process into production,the variation of rolling load and deformation behavior in such cross shear cold-rolling have been investigated experimentally further on the same 4-high mill and the results are revealed in this paper.Under different conditions of mismatched ratio of roll-speed,back and front tension and lubrication,tested strips of annealed mild steel with thicknesses of 0.027,0.047 and 0.063 mm were rolled to the thickness below conventional minimum limit until the forced-contact between two work roll ends occured on both sides.Apart from such surveyed parameters as roll force,rolling torque,tensions,pass reductions,forward slips relative to the slower roll and the speed of faster roll,a new method was introduced to ascertain whether a forced-contact between two work roll ends has actually occured and how it occurs (on one side only or both sides simultaneously).Experimental curves as shown in this paper show the dependences of rolling force and torque and forward and backward slips on pass reduction under different technical conditions and so indicate the performance characteristics of rolling load variation in cross shear cold-rolling for ultra-thin strips.A method for caluclating rolling force,also applicable to estimate if the forced-contact between two work roll ends occurs,has been proposed in detail,by which we have satisfactory results in accordance with experiments.The investigation is useful to providing the data and calculating method for rolling load in rolling mill design and rational rolling schedule.
