The invention discloses hot rolling strip steel for a wear-resisting carrier roller and a manufacturing method. The strip steel comprises ingredients including, by mass, 0.050%-0.150% of C, 0.10%-0.30% of Si, 1.30%-1.90% of Mn, not larger than 0.010% of P, not larger than 0.005% of S, 0.02%-0.05% of Al, 0.01%-0.04% of Nb, 0.01%-0.04% of Ti, 0.02%-0.06% of V, 0.15%-0.40% of Cr and the balance Fe and inevitable impurities. The technical problems that in the prior art, base metal or a welding seam cracks when a welding pipe for the carrier roller is used for manufacturing a pipe, and the machinability of the welding pipe for the carrier roller and the using requirement have conflicts are solved, and the technical effects that at home and abroad, the high strength welding pipe is adopted for replacing a seamless steel tube for manufacturing the carrier roller, the steel plate yield strength is larger than 500 MPa, the strength of extension is larger than 600 MPa, the ductility is larger than 30%, the plate shape and the surface quality are excellent, the excellent cold forming property and weldability are achieved for adapting to the machining requirements of producing the welding pipefor the carrier roller through roller molding, meanwhile, the good abrasive resistance is achieved, the using requirement of the welding pipe for the carrier roller is met, and the economical and practical performance is achieved.
