The invention discloses a rough rolling production method. The method comprises the steps that 1) a new rough rolling working roller serves as a standby roller to be off-machine for later use after rolling one million tons of strip steel; and 2) when an on-machine working roller breaks down, the on-machine working roller is replaced with the standby working roller. According to the method, after the new rough rolling working roller rolls one million tons of strip steel, the friction coefficient of the working roller gradually rises, the rough rolling plate cut gradually tends to be stable, and therefore the new rough rolling working roller can be off-machine to serve as the standby working roller for later use; and when the on-machine working roller breaks down, for example, the working roller gets a burn, gets damaged, gets broken or the like, if the thin-specification strip steel is subsequently rolled, rolling needs to be continuously carried out by using the standby working roller which rolls one million tons of strip steel, and therefore the rejection rate of the strip steel of the thin specification can be decreased. The method has the advantages that the production quality and the production efficiency of steel rolling can be effectively guaranteed, and in addition, workers can be guaranteed to arrange production plans reasonably.
