Abstract

The invention discloses a carbon sleeve roller, and relates to the technical field of strip steel continuous annealing. The technical problem of high positioning difficulty of a carbon sleeve and a roller core in strip steel annealing in the prior art is solved. The carbon sleeve roller comprises a roller core and a carbon sleeve, the carbon sleeve sleeves the roller core, a positioning key groove is formed in one axial end of the carbon sleeve, a sliding key groove is formed in the other axial end of the carbon sleeve, the sliding key groove is formed in the axial direction of the carbon sleeve and provided with a positioning key, the sliding key groove is provided with a sliding key, the positioning key and the sliding key are connected with the roller core, and the positioning key is matched with the positioning key groove to realize axial positioning and circumferential positioning of the carbon sleeve. Through the matching of the positioning key and the sliding key and the adoption of an axial positioning and circumferential positioning separation method, the problem of inconsistent deformation of the carbon sleeve and the roller core is effectively solved, the adverse situation of carbon sleeve breakage is improved, the stable operation of a continuous annealing furnace is facilitated, the failure rate of a unit is reduced, the production efficiency of the unit is improved, and the carbon sleeve roller plays a very important role in the quality of strip steel and other products.

Description

technical field [0001] The invention relates to the technical field of continuous annealing of steel strips, in particular to a carbon-covered roll. Background technique [0002] At present, the graphite carbon sleeve is the best hearth roll for the support and transmission of the steel strip in the continuous annealing furnace of silicon steel. Due to the relatively low hardness and strength of the carbon sleeve itself, it must be used in the continuous annealing furnace of the strip steel. Hot metal roll cores are assembled together and are called charcoal sleeved rolls. Due to the large difference in expansion coefficient between the carbon sleeve and the roller core, the high-temperature deformation is different, which makes the positioning of the carbon sleeve difficult. [0003] At present, the positioning of carbon sleeve rollers has several forms, such as plate pin connection, disc pin connection, and rectangular pin connection. Due to the inconvenient installation...
