Description

Technical Field

[0001] The utility model belongs to the field of plate production equipment, in particular to a roller replacement device for a cleaning section of a continuous plate production line. Background Art

[0002] At present, domestic continuous production lines for plates use two structural forms: vertical annealing furnace and horizontal annealing furnace to produce galvanized, aluminum-zinc, zinc-aluminum-magnesium and other products and to anneal plates. Before annealing the plates, alkali immersion, alkali brushing, electrolytic cleaning, bleaching and brushing, and desalted water high-pressure cleaning (cleaning section process) are required to ensure that the plate surface is clean when entering the annealing furnace, and to ensure the adhesion of the coating on the base surface of the plate, and to reduce the impact of the iron powder generated during the rolling process of the plate entering the zinc pot and reacting with the zinc liquid to form an iron-aluminum alloy zinc slag on the plate surface.

[0003] The plate comes out of the alkali immersion (tank) and enters the horizontal alkali brushing (tank). There are squeeze rollers before and after the alkali brushing (tank) to keep the plate stable. At the same time, the function of the squeeze roller is to bring the solutions of different concentrations in the upper and alkali brushing (tank) into the tank behind, so that the concentration of the solution in the next process increases and does not meet the process requirements. There are generally four or six brush rollers and support rollers corresponding to the brush rollers in the alkali brushing (tank) (to prevent the plate from shaking during brushing, and the number is evenly divided between the upper and lower plate surfaces). According to the requirements, in order to completely brush out the tiny iron powder in the tiny gaps on the surface of the plate, the upper and lower support rollers are respectively higher or lower than the strip rolling line, and the circumference of the strip is The brush roller with bristles is at the center of the support roller, and the other side of the plate strip rotates at a constant speed against the running direction of the plate to clean out the iron powder hidden in the pores on the surface of the plate; similarly, the rollers in the bleaching and brushing (trough) have the same function as the rollers in the alkaline brushing (trough), but the solution concentration is lower. Therefore, the rollers in the two troughs need to be replaced regularly after wear; in order to save space, the horizontal annealing furnace is mostly installed on a platform at a certain height from the floor, and the troughs of the cleaning section are installed under the platform. In this way, the center of the crane for lifting the roller cannot reach the center of the axial direction of the rollers in the cleaning section, and a roller changing vehicle that can move on the floor needs to be used to extract and reinstall the assembled rollers to be replaced;

[0004] In summary, the utility model provides a roller replacement device for a continuous plate production line cleaning section to solve the above problems. Utility Model Content
