Description

High-speed threading guide plate table

Technical Field

The utility model relates to a rolling technical field of belted steel, concretely relates to high-speed threading deflector plate platform.

Background

At the outlet of the strip steel cold continuous rolling unit, two recoiling machines or a double-reel recoiling machine are usually used to realize continuous and alternate strip steel recoiling, and the former has wider application due to simple structure and convenient maintenance. A double-coiling machine production mode is adopted, in order to ensure that the sheared strip steel is quickly switched to enter different coiling machines, a strip threading guide plate table is generally arranged between the two coiling machines, and when the first coiling machine swings the tail, the head of the next strip steel is fed into the second coiling machine through a conveying belt of the strip threading guide plate table. In the process, the strip steel and the conveying belt must run synchronously, otherwise strip steel piling accidents are easy to happen.

The conventional threading guide plate platform conveys strip steel by utilizing a conveying belt, a strip head cannot be well attached to the belt, and the strip steel is easy to arch during high-speed threading to cause steel piling. The conventional threading guide plate table is provided with an electromagnet below a conveying belt, and the belt steel is prevented from arching by utilizing the electromagnet to adsorb the belt steel. The structure is convenient for adjusting the electromagnetic attraction, but has higher cost and inconvenient maintenance, is mainly used for carbon steel continuous rolling mills, and is not used for stainless steel continuous rolling mills.

Another problem with the double-reel production is that if the coil on one of the reels collapses, the coil-unloading process is very difficult. Usually, the steel coil is forcibly unloaded from the coiling machine manually, and then the residual waste coil is cut layer by layer, so that the stop time of the treatment process is long and safety accidents are easy to happen. Therefore, it is necessary that the two coilers have a rewinding function to rewind the collapsed coil to another coiler and then unload the coil. The existing continuous rolling mill group generally does not have the function due to the limited function of the equipment.
