The invention relates to a hot rolling and finish rolling multi-level threading speed control method, and belongs to the technical field of steel rolling control. According to the hot rolling and finish rolling multi-level threading speed control method, in a group of steel rolling mill provided with finish rolling temperature and strip steel end location monitoring, the initial threading speed of each corresponding machine frame in a group of machine frames is determined as a matter of routine; when the monitored finish rolling temperature is lower than a target temperature, the speed of next time threading of a first machine frame is improved according to a scheduled speed-up ratio; if the monitored finish rolling temperature is still lower than the target temperature, the threading speed of a next machine frame is improved according to the scheduled speed-up ratio until before the middle machine frame; if the monitored finish rolling temperature is still lower than the target temperature, the second step is repeated; and after the threading, a strip steel end is output from a speed-up machine frame, enters in front of a bite steel of a next machine frame with the initial threading speed, and controls all speed-up machine frames to recover into original corresponding initial threading speeds. By means of the method to the maximum extent, the threading speed of the current machine frame can be improved appropriately to achieve the purpose that the finish rolling temperature is kept not to lower than a threshold value.
