The invention discloses a waterproof control device and method for a loop roller of a hot continuous rolling mill, and belongs to the field of hot rolling devices. According to the waterproof control device, a surfacing layer is arranged on the outer surface of a loop roller body; tungsten carbide spraying layers are arranged on the outer surfaces of first steps at the outer side ends of a transmission side roller core and a working side roller core; a first oil seal and a waterproof sealing ring are arranged between a transmission side bearing seat end cover and the first step of the transmission side roller core; a second oil seal and a check ring for a hole are arranged between a transmission side bearing seat base and a spacer bush in a sleeving manner; a cooling water outlet pipe is of an arc bent pipe structure. By redesigning a loop roller sealing structure, a processing technology and a heat treatment mode of the outer surface of the end part of the loop roller, abrasion of the sealing ring and the lo
