Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of guide wheels for roll bearing seats in galvanizing production lines, and particularly to a guide wheel for a temper mill roll bearing seat in a continuous galvanizing production line. Background Art
[0002] Continuous galvanizing refers to a surface treatment technology in which a layer of zinc is plated on the surface of metals, alloys or other materials for purposes such as aesthetics and rust prevention. The main method currently used is hot continuous galvanizing. Hot continuous galvanizing has evolved from the older hot-dip galvanizing method. Since it was applied to industry in France in 1836, it has a history of one hundred and forty years. However, the hot continuous galvanizing industry has developed on a large scale in the past thirty years along with the rapid development of cold-rolled strip steel. In a modern continuous galvanizing workshop for strip steel, the strip steel starts from the uncoiler and passes through an annealing furnace, which is equipped with combustion, oxidation, and reduction zones; then the strip steel enters the zinc pot under a protective atmosphere; after leaving the zinc bath, the strip steel passes through wiping rolls or air knives to level the zinc layer. The galvanized strip steel also passes through a cooling zone before being coiled. To ensure the continuous passage of the strip steel through the annealing furnace and the zinc bath, buffer mechanisms are set before and after the zinc pot to control the running speed of the strip steel. There is strip steel reserved at the starting end of the production line to ensure that the starting end of the reserved strip steel is welded to the end of the previous coil of strip steel. The running speed of the strip steel can reach 200 m / min or higher, which depends on the thickness of the strip steel and the thickness of the coating to be applied.
[0003] The function of the work roll bearing seat of the temper mill in the continuous galvanizing production line is to fixedly support the bearing, and at the same time control the position of the roll in the temper mill housing to ensure smooth operation and rolling accuracy. Therefore, its accurate and stable introduction is crucial. The guide wheels provided on both sides of the bearing seat are used for the bearing seat and the roll sleeve group to smoothly enter the temper mill housing. The existing guide wheels use rolling bearings, which contain a large number of rolling elements, and there is no anti-slip structure on the inner and outer rings of the bearing. During the process of introducing and removing the bearing seat and the roll sleeve group, it is easy to slip out, resulting in scrapping and increasing the spare part cost. Therefore, it is necessary to design a guide wheel for a temper mill roll bearing seat in a continuous galvanizing production line to meet the usage requirements while reducing losses and costs.
