Description

TECHNICAL FIELD

[0001] The utility model relates to aluminium alloy coiled material hot rolling equipment technical field, specifically is a reel water cooling structure for aluminium alloy production. BACKGROUND

[0002] After aluminium alloy ingot is heated at high temperature, through the expansion and contraction of the reel drum, the winding and unloading operation of the aluminium alloy coiled material is realized.

[0003] During the winding process, the temperature of the aluminium alloy coiled material is kept between 200 DEG C and 300 DEG C, due to the heat conduction effect, the reel drum temperature rises rapidly, therefore the thermal expansion and contraction phenomenon will cause the movement of the reel sector plate to be blocked, which brings great inconvenience to production.

[0004] To solve this problem, the cooling methods used in production are: reel outside cooling (spraying, atomization or cold air blowing) and reel inside cooling (circulating water cooling, air cooling).

[0005] As for the reel outside cooling, the cooling effect of atomization and air cooling is not obvious, and when using emulsion spraying method for cooling, the evaporation of emulsion will cause pollution of the site environment, and other metal impurities in the equipment will be brought into the emulsion system, which will form product defects in the subsequent production.

[0006] As for the reel inside cooling, the effect of air cooling is not obvious due to the influence of the circulating loop (the amount of air out of the reel sector plate cannot be felt by hand in production). As for the circulating water cooling inside the reel, from the published related patents, if the circulating water is arranged on the sector plate, the cooling water circuit is led out along the radial direction of the sector plate. If the circulating water is arranged on the moving spindle, the cooling water enters from the tail of the spindle and is discharged from the end of the spindle. These two methods need to repeatedly install water pipe joints in production, on the one hand, water leakage is easy, on the other hand, the labor intensity is large, the production efficiency is low, and many inconveniences are brought to online production.

[0007] At present, with the increase of market demand for wide and high-precision aluminium alloy strip, the width of the strip has increased from 1850mm to 2800~3300mm, the length of the sector plate of the reel is greater than the width of the strip, and the length of the spindle is at least twice the width of the strip, that is, the length of the spindle is greater than 6500mm. At this time, the circulating holes are opened on the sector plate or the spindle, on the one hand, the machining difficulty and precision increase, on the other hand, the cooling water holes have small diameter, and the cooling and cooling effect is not ideal. Therefore, we propose a reel water cooling structure for aluminium alloy production. CONTENT OF THE UTILITY MODEL
