Effect of Reversing Cold Rolling on Texture and Ferrite Grain Size of Steel Sheet

摘要: 在实验室通过可逆式和连续式冷轧及退火模拟试验,研究了可逆式冷轧对DX51D(低碳铝镇静钢)和DX54D(无间隙原子钢)钢板织构及铁素体晶粒尺寸的影响。试验结果表明:①可逆式冷轧态试样α取向线{115}、{335}织构密度明显大于冷连轧试样,可逆式与连续式冷轧态试样γ取向线{111}织构密度无明显差别;②DX54D可逆轧制退火态试样γ取向线{111}织构密度大于冷连轧试样,其α取向线织构密度则与冷连轧试样相当;③DX51D可逆轧制退火态试样织构密度与冷连轧试样相当;④可逆轧制退火态试样的铁素体晶粒尺寸小于冷连轧试样。Abstract: A study on effect of reversing cold rolling on texture and ferrite grain size of DX51D(LCAK steel) and DX54D(IF steel) has been done by simulating experiment of reversing and continuous cold rolling and annealing in the laboratory.The results show that the α-rib {115} and {335} texture density of reversing rolling sample is obvious higher than that of continuous rolling,and the γ-rib {111} texture density of reversing rolling sample is equivalent with that of continuous rolling;the γ-rib {111} texture density of reversing rolled DX54D annealing sample is higher than that of continuous rolling,and its α-rib texture density is equivalent with that of continuous rolled annealing sample;the texture density of reversing rolled DX51D annealing sample is equivalent with that of continuous rolling;the ferrite grain size of reversing rolled annealing sample is less than that of continuous rolling.
