Abstract

The invention belongs to the technical field of steel rolling, and discloses a roller shape design method of a furnace roller of a continuous annealing furnace. The method comprises the following steps of: obtaining a furnace roller parameter of the continuous annealing furnace; setting a buckling coefficient according to a buckling risk grade of the continuous annealing furnace; setting a rollershape curve into a middle flat and straight section and two side curve sections by adoption of a roller shape curve design model; and optimizing the roller shape curve on the basis of the furnace roller parameter and the buckling coefficient. According to the method, the roller shape curve is set in allusion to practical buckling condition of furnace section of the continuous annealing furnace, sothat reliable buckling inhibition effect is realized and then the product quality is enhanced.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a furnace roll for a continuous annealing furnace and a roll profile design method for the furnace roll. Background technique [0002] At present, the furnace roll types of continuous annealing furnace mainly include flat roll, crown roll, single taper roll and double taper roll. During the production process, the defects of strip deviation and buckling are often prone to occur. [0003] Specifically, the flat roll has good contact with the strip, but the ability to prevent the deviation of the strip is poor; compared with the flat roll, the crown roll has a certain ability to prevent deviation, but it is easy to cause the strip to buckle; Compared with the tapered roll, when the crown height is the same, since the crowned roll does not have a sharp point and is in full contact with the strip, its anti-bending ability is higher than that of the tapered roll, but due to its...
