Removing device of tail coil of cold-rolling unit and tail coil removing method thereof

Abstract

The invention discloses a removing device of a tail coil of a cold-rolling unit. The removing device of the tail coil of the cold-rolling unit comprises a support. The top of the support is an inclined face. A coil pushing plate, a coil partition plate and a baffle are arranged on the top of the support. The coil pushing plate and the coil partition plate are connected with the support through a rotating shaft a and a rotating shaft b correspondingly. The rotating shaft a and the rotating shaft b are connected with a coil pushing hydraulic cylinder and a coil partition hydraulic cylinder correspondingly through hinged joints. The coil pushing hydraulic cylinder and the coil partition hydraulic cylinder are both connected with the support. According to the removing device of the tail coil of the cold-rolling unit, the tail coil can be rapidly and effectively removed without the need for a crane. A tail coil removing method comprises the following steps that firstly, the tail coil is made to be identical with the top of the support in height; secondly, the coil pushing hydraulic cylinder drives the coil pushing plate to push the tail coil to reach the coil partition plate; and thirdly, the coil partition hydraulic cylinder is started, the coil partition plate is made to be unfolded, the tail coil rolls to the baffle along the support, and a forklift lifts the tail coil and conveys the tail coil to a workshop tail coil storage area. By the adoption of the tail coil removing method, the work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical rolling and cold rolling mills, and relates to a device for removing tail coils of a cold rolling mill, and also relates to a method for using the device to remove tail coils. Background technique [0002] In the cold rolling unit of a steel mill, in order to avoid affecting the product quality, the last few rounds of rolling and the strip head are usually cut off during the rolling process of the steel strip. These unqualified steel strips finally form a tail coil, so the tail coil The removal device is an indispensable equipment for every unit. The traditional tail coil removal method is to use the coil trolley to transport the tail coil, and then use the crane to lift the tail coil to the waste coil area. Generally, the tasks of the coil transport trolley and the crane in the cold rolling workshop are very busy. , so in practice, the original tail volume removal method has seriously affe...
