Abstract: Front end bending is a common phenomenon in the hot rolling process of plate and strip.Aiming at this problem,in this work,the finite element method was used to study the metal flow of the rolling deformation zone for hot rolling pure titanium coil.The results show that the metal flow of pure titanium assumes the "w"shape,which is different from that of 20-steel with "c"shape,indicating that the control technology of front end bending for plain carbon steels is not completely suitable for pure titanium rolling.We also analyzed the effects of diameter difference between top and bottom work rollers,temperature difference between upper and lower workpiece surfaces,reduction rate,oxide scale thickness and friction coefficient on front end bending,and found that the temperature difference of workpiece surfaces and friction coefficient are the two significant factors that influence the front end bending during hot finish rolling process of pure titanium.From the perspective of temperature controlling,the technological measures that avoid the front end bending of pure titanium coil were made,effectively solving the front end bending problem,which is of practical application value for reducing the loss of cutting head and improving the rolling yield.
