The invention relates to a method for controlling equal-gap steel rolling, belonging to the technical field of
metallurgy. In the method, a
computer control system is used. The method comprises the following control steps of: judging a current steel extraction
heating furnace and a next steel extractable
heating furnace; reading the action time of a steel extraction
machine transmitted by a monitoring sensor of the next steel extractable steel
heating furnace as well as a roller table running speed and a practical time interval between the reach of two front adjacent plate blanks to a rollingmill transmitted by a speed senor and a time sensor on a roller table; retrieving a store formula and calculating corresponding
waiting time of the next steel extractable heating furnace; when the
waiting time is reached, controlling the heating furnace to extract steel; and calculating the next steel extraction
waiting time every time steel extraction is finished and determining a next steel extraction heating furnace according to a minimum waiting time principle. Due to the adoption of the method, the tendency to equal-interval rolling is automatically realized by dynamic adjustment, self-
adaptation to various complex environments can be realized, the organized production efficiency of a steel rolling line is increased, the stability of the rolling tempo is improved, the
energy consumption is lowered, and the problem of the influence on coiled sheet quality caused by unreasonable production organization is solved.
