Effect of friction on hot rolling and annealing texture of IF steel in ferrite region

if steel usually goes through hot rolling, cold rolling, annealing and other processes. However, rolling texture with high fiber texture occupancy can also be obtained by ferrite hot rolling technology, and the stamping performance is good after direct annealing. If steel usually goes through hot rolling, cold rolling, annealing and other processes to check whether the lifting action of the lower jaw base is in line with the text characters shown on the button. However, the rolling texture with high fiber texture occupancy can also be obtained by ferrite hot rolling technology. After direct annealing, the stamping performance is good, and the hot strip cooling simplifies the process and reduces the cost. However, when if steel is hot rolled in the ferrite zone, due to the friction effect of the roll on the plate, the texture distribution in the thickness direction is uneven; Shear deformation occurs on the surface of the steel plate, forming a strong shear texture. After annealing, the texture inhomogeneity along the thickness of the steel plate still exists, which is unfavorable to improve the deep drawing performance of the steel plate

Xu Lingfeng and other scholars used X-ray diffraction to analyze the evolution of IF steel ferrite hot rolling texture and annealing texture, and carried out if steel ferrite hot rolling on a laboratory hot rolling mill, and studied the effect of friction on if steel ferrite hot rolling and annealing texture. The results show that when rolling without lubrication, Strong Gauss texture components {110 、 ＜ 001 ＞ and weak fiber texture are formed on the surface of steel plate, resulting in high strength of Gauss component in recrystallization texture and low strength of fiber texture; during lubrication rolling, the strength of Gauss texture component on the surface of steel plate decreases, {100 、《 011 》, the fiber texture strength increases, and the fiber texture strength increases after annealing. The center of the steel plate is less affected by friction, and the elimination method during the rolling process: clean the pendulum bearing, toothed rod, pointer, and wire wheel to develop into strong and fiber texture, and the fiber texture composition after annealing is the main texture component
