Non-hole rolling material shape control method

The invention discloses a non-hole rolling material type control method. The method comprises the steps that rolling is carried out on a rolling system which comprises horizontal and vertical alternate roughing mills and is provided with guides in front of and behind each rolling mill, the number of the roughing mills is six, 1 #-5 # rolling mills are non-porous, 6 # rolling mills are round-hole-shaped, and 5 # rolling mills are round-hole-shaped rolling mills; and rapid conversion and continuous rolling of square billets with different sections of 160mm and 170mm are realized by adjusting the size and the extension coefficient of each pass and the sizes of an inlet guide side guide plate and an outlet guide side guide plate. According to the method, the material type of each pass of non-pass rolling, the size of the inlet guide and the size of the outlet guide and control key points are given, so that clear guidance is provided for the non-pass rolling technology, and the occurrence of steel pouring events i
