There is described multi-stand rolling mill with stands having four motorized rolls and provided with controls out- side the stand and retractile spindles, which comprises a central body with said stands; a first platform (41) on a side charge position carrying the substitution stands; a second platform (42) on a side discharge position, opposite to said side charge position; a transversal translation device (43, 44) adapted to push the substitution stands against the corresponding stands to be substituted on the central body. The stands to be substituted translate on the second platform, and the substitution stands substitute the stands to be substituted in the central body.
