The invention provides a carbon sleeve roller protrusion judging and removing method. The method comprises the following steps that firstly, when pits are formed in strip steel, the distance l1 between the pits is measured through a straight ruler; secondly, all carbon sleeve rollers are divided into an N1 set and an N2 set to be checked according to a half method; thirdly, the linear velocity of the N1 set of carbon sleeve rollers is changed, and the linear velocity of the N2 set of carbon sleeve rollers is kept unchangeable, wherein if the distance between the pits of the strip steel is changed, it is judged that protrusions exist in the N1 set of carbon sleeve rollers, and if the distance between the pits of the strip steel is not changed, it is judged that the protrusions exist on the N2 set of carbon sleeve rollers; fourthly, the judged N1 or N2 set of carbon sleeve rollers with the protrusions are further checked according to the second step and the third step till the carbon sleeve rollers with the protrusions are checked; and fifthly, the linear velocity of the carbon sleeve rollers with the protrusions is changed, the rotating speed of other carbon sleeve rollers is kept unchangeable, and the carbon sleeve rollers without the protrusions run. The carbon sleeve roller protrusion judging and removing method has the beneficial effects that firstly, production is not affected, and a large number of economic losses caused by shutdown for maintenance can be reduced; secondly, operation is simple and fast, and operators can be competent for the job through the simple training; and thirdly, the service life of the carbon sleeve rollers can be greatly prolonged.
