Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metallurgical strip steel galvanizing, in particular to a position adjustment device for a sinking roller of a hot-dip galvanizing unit. Background Art
[0002] The production process of a hot-dip galvanizing line involves the steel strip exiting the return furnace and entering a zinc pot filled with molten zinc at 450-600°C. Once in the zinc bath, the strip is coated with zinc and then lifted vertically upward by the zinc bath's sinking rollers. These rollers are suspended in the zinc bath by beams and rods. As the strip exits the zinc bath, air from an air knife removes excess zinc and evenly coats the strip. As the rollers remain immersed in the zinc bath, corrosion from the zinc bath and wear between them and the running strip cause their outer diameter to change. This alters the angle between the strip and the furnace nose channel, causing collisions and potentially equipment failures. Furthermore, this change in the outer diameter of the rollers can cause the strip to deviate, affecting the quality of the galvanizing process and posing safety risks. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to provide a position adjustment device for the sinking roller of a hot-dip galvanizing unit. The position of the sinking roller is adjusted by the device, thereby adjusting the angle between the strip and the furnace nose channel and adjusting the deviation of the strip, thereby reducing the equipment failure rate, ensuring the reliable and stable operation of the galvanizing production line, and eliminating safety hazards during the operation of the production line.
