Method and system for preventing reel sinking deformation of galvanized steel reels

Abstract

The invention discloses a method and system for preventing reel sinking deformation of galvanized steel reels. The method includes the steps that respective finite element grid cell node models with helical curve characteristics are built according to the specifications and the steel types of the galvanized steel reels, respective finite element calculating models are further built in cooperation with tension reeling curves, then respective reel sinking deformation critical load values of the galvanized steel reels are calculated through the respective finite element calculating models, and a reel sinking deformation critical load library is constructed in a systematic way. The reel sinking deformation critical load library is transmitted to a stacking control system to be read and used, so that the stacking control system optimizes the stacking positions of the galvanized steel reels in practical production, and the reel sinking deformation probability and the reel sinking deformation times of the galvanized steel reels, in particular to the galvanized steel reels sensitive to reel sinking deformation, in the stacking process and the long-distance transport process are effectively reduced.

Description

technical field [0001] The invention belongs to the continuous hot-dip galvanizing process technology of cold-rolled strip steel, and in particular relates to a method and a system for improving the collapse and deformation of galvanized steel coils. Background technique [0002] The continuous hot-dip galvanizing production line for strip steel was first realized in industrial application by Polish engineer Sendzimir in the 1930s. It integrates multiple processes such as strip cleaning, annealing, hot-dip galvanizing, skin pass, automatic surface inspection, oiling, recoiling or shearing into a complete production unit, which can make strips obtain no bonding , Hot-dip galvanized products with no defects such as sand intrusion and good surface quality. [0003] During the coiling process of the continuous hot-dip galvanized production line, the strip steel depends on the torque of the coiler motor to generate a certain coiling tension, which in turn causes a certain tangen...
