Gear shifting method continuous hot galvanizing production line

Abstract

The invention discloses a gear shifting method continuous hot galvanizing production line. Fifty-two devices are connected in sequence. Automatic gear shifting devices are arranged in a first tensioning machine, a second tensioning machine, a third tensioning machine, a fourth tensioning machine, a fifth tensioning machine, a sixth tensioning machine, a seventh tensioning machine and a rolling machine in the gear shifting method continuous hot galvanizing production line, and all the automatic gear shifting devices are synchronously fast and slow through one main adjusting switch. The problem of high investment caused by large torque and large motor power of a thick plate wire is solved, and meanwhile the common problem that only one kind of products can be produced due to the too low speed of a traditional production line is solved. The speed can be greatly increased when a sheet is produced by automatically switching gears, the requirement for producing sheets with the thickness of 0.5 mm or higher is effectively met, and different functions needed in large-span production of sheets and thick plates of the production line are achieved.

Description

technical field [0001] The invention relates to a production line, in particular to a continuous hot-dip galvanizing production line by shifting gears. Background technique [0002] No matter how the traditional continuous hot-dip galvanized strip production line is improved, its power design principle still takes the maximum plate width, maximum plate thickness, and maximum line speed as the assessment indicators, and then calculates the motors of each part based on the maximum torque required by each tension machine Power, and according to the development of electrical appliances in each period, improve the automation of production lines. [0003] More than 95% of the galvanized production lines in my country are the production capacity with a plate width of no more than 1250mm and a plate thickness of no more than 1.5mm. About 90% of the galvanized sheets in the normal production of actual enterprises are 0.3mm-0.5mm thin specifications, with a specification of 0.6mm The ...

AI Technical Summary

Problems solved by technology

Therefore, the traditional thick plate production line is limited to the production plate thickness between 2.0mm-5.0mm. If the plate thickness is less than 2.0mm, the waste of energy consumption will increase, and the cost will increase, which is very uneconomical.

Therefore, the thick plate production line not only has a large one-time investment, but also has a slow line speed and consumes a lot of power for a long time.
