The invention discloses a rough rolling roller pass matching method applied to a steel rolling process. The method is characterized in that rough rolling roller 1V pass, 2H pass, 3V pass, 4H pass and 5V pass are included in sequence, the widths and heights of the 1V pass, the 2H pass, the 3V pass, the 4H pass and the 5V pass are in a progressive decreasing state, and after rollers corresponding to one or more different pass are used up and offline, the pass size is enlarged, and the roller is processing into the pass similar to the pass of the roller. According to the rough rolling roller pass matching method applied to the steel rolling process, according to the characteristics that shapes are similar, and the sectional areas are different, the abnormal abrasion loss caused by manual machining of the rollers in different periods is reduced to the maximum extent by utilizing the machining and roller matching principle that a large roller replaces a small roller and a box roller replaces a square roller; and m
