Abstract

The invention discloses a furnace roller for a tunnel type furnace kiln, in particular to a furnace roller on a roller bed used for conveying metal thin strips in the process of conducting continuous high temperature heat treatment on the metal thin strips in a tunnel type furnace kiln. The furnace roller comprises a shaft body and a roller shaft. The furnace roller is characterized in that the shaft body is a solid ceramic roller; the diameters of the segments of the two ends of the shaft body are each smaller than the diameter of the middle segment of the shaft body; the opposite side faces of the segment of each end of the shaft body are each a plane; and the two planes at the same end are parallel to each other. The two ends of the shaft body are each provided with a stainless steel shaft head; the stainless steel shaft heads and the shaft body are coaxial; a shaft sleeve is arranged at the inner end of each stainless steel shaft head; one end of each shaft sleeve is a closed end; and each closed end and the inner end of the corresponding shaft head are of an integral structure. The shape of an inner cavity of each shaft sleeve is the same as the shape of the segment of the corresponding end of the shaft body, and the segment of each end of the shaft body extends into the other end of the corresponding shaft sleeve in a close manner. The furnace roller is not prone to damage and low in maintenance cost. By means of the furnace roller, production cost can be reduced.

Description

technical field [0001] The invention relates to a furnace roll. Specifically, it is the furnace roller on the roller table used to transport the metal strip during the continuous high-temperature heat treatment process of the metal strip in the tunnel furnace. Background technique [0002] At present, the furnace rollers on the roller table used to convey the metal strip during the continuous high-temperature heat treatment process of the metal strip in the tunnel furnace kiln are all traditional furnace rollers. This traditional furnace roller mainly contains the following two types: one is to put a ceramic roller sleeve on the stainless steel shaft, and a stainless steel end sleeve is respectively arranged at the two ends of the ceramic roller sleeve. The outer end of the stainless steel end sleeve is fixed with the stainless steel shaft by means of screws, so that the circumferential direction of the ceramic roller sleeve and the stainless steel shaft is in a fixed fit. ...
