Abstract

The invention discloses a nodulation-free furnace roller of a roller-hearth type thermal treatment furnace. The nodulation-free furnace roller comprises shaft necks, wherein the first and second shaft necks are respectively fixed on both sides of a roller body, a baffle is respectively fixed at one end of the first shaft neck and one end of the second shaft neck, and is located in the roller body, the shaft necks are connected with the other end of the first shaft neck, end caps are sleeved on the shaft necks, heat-resisting materials are filled in the first and second shaft necks, a first slag area is located outside the first shaft neck, a second slag area is located outside the second shaft neck, a bearing pedestal is located on one side of the second slag area and fixed together with a bearing, a coupler is connected with the bearing, and a motor is connected with the coupler. The roller body is made from ceramic fibers. The nodulation-free furnace roller disclosed by the invention can be used for solving the technical problem that the product quality is affected due to scratching of a heat treatment panel caused by swelling of the furnace roller and nodulation, and the surface of the heat treatment panel is not damaged.

Description

technical field [0001] The invention relates to a furnace roller, in particular to a nodulation-free furnace roller for a roller hearth heat treatment furnace. Background technique [0002] Roller hearth heat treatment furnace is the only industrial furnace in the metallurgical industry that can perform continuous heat treatment (quenching, normalizing, annealing, tempering, solid solution, etc.). The furnace roll of the roller hearth heat treatment furnace adopts the furnace roll of the roller hearth heat treatment furnace. Although the roll body is made of heat-resistant alloy, at high temperature, the surface oxidation will still produce bulges and nodules. Bulges and nodules will scratch the surface of the heat-treated sheet and affect the surface quality of the sheet. Some special steels that do not allow surface grinding can only be downgraded or scrapped, which affects the economic benefits of heat treatment companies. Contents of the invention [0003] The techni...
