Abstract

Patente de Invenção: "CILINDROS PARA DISPOSIçãO NO LADO DE ENTRADA OU NO LADO DE SAìDA DA ZONA DE TêMPERA DE UM FORNO DE RECOZIMENTO CONTìNUO E UNIDADE DE USO DE CILINDROS DA ZONA DE TêMPERA". é fornecido um cilindro que possa ser disposto antes e/ou após uma zona de têmpera de um forno de recozimento contínuo. O cilindro tem um perfil predeterminado satisfazendo Lc <242> 0,7 x W~ min~; R = -0,1 x 10^ -3^ até 0,2 X 10^ -3^; e TR <242> 20, onde Lc representa o comprimento (mm) de uma porção plana no centro do cilindro, W~ min~ representa a largura mínima (mm) de uma tira de aço, R representa a inclinação das porções afiladas dispostas dos dois lados do cilindro, e TR representa o raio de curvatura (m) dos limites entre a porção plana e as porções afiladas. O cilindro pode ser usado como cilindro de soleira e/ou cilindro tensor disposto no lado da entrada e/ou no lado da saída da zona de têmpera.Invention Patent: "CYLINDERS FOR DISPOSAL ON THE INPUT SIDE OR OUTPUT OF THE TEMPERATURE ZONE OF A CONTINUOUS RECOVERY OVEN AND UNIT FOR USE OF CYLINDERS IN THE TEMPERATURE ZONE". a cylinder is provided which can be disposed before and / or after a quenching area of a continuous annealing furnace. The cylinder has a predetermined profile satisfying Lc <242> 0.7 x W ~ min ~; R = -0.1 x 10 ^ -3 ^ to 0.2 X 10 ^ -3 ^; and TR <242> 20, where Lc represents the length (mm) of a flat portion in the center of the cylinder, W ~ min ~ represents the minimum width (mm) of a steel strip, R represents the slope of the tapered portions arranged in the two sides of the cylinder, and TR represents the radius of curvature (m) of the boundaries between the flat portion and the tapered portions. The cylinder can be used as a threshold cylinder and / or a tensioning cylinder arranged on the entrance and / or exit side of the tempering zone.
