Problems solved by technology

[0006] The purpose of the present invention is to provide a rolling mill outlet device that can realize constant-speed rolling. Due to the defect of strip head-to-tail speed up and down caused by the bite of the coiler, the rolling mill can maintain constant rolling at a higher speed by adding a tension roll group and a looper that are easy to wear the strip after the rolling mill, so as to improve productivity , to improve strip thickness and shape quality

Embodiment Construction

[0021] see figure 2 , a rolling mill exit device that can realize constant-speed rolling, including a tension roll set 3 and a looper 4, the output of the rolling mill 1 is connected to the tension roll set 3, the tension roll set 3 is connected to the looper 4, and the looper 3 is connected to another tension roll Roller group 3, another tension roller group 3 is connected to crimping machine 5. see Figure 8 The tension roller group 3 includes a moving roller 31 and a fixed roller 32, the moving roller 31 is installed on the outer ring of the rotatable disc 33, the fixed roller 32 is installed in the center of the disc 33, and the circumference of the outer ring of the disc 33 is opened. There is a tooth shape, and the tooth shape is meshed with the gear driven by the motor, and the rotating disk 33 can make the moving roller 31 turn to the working position and the belt threading position. The looper 4 includes upper and lower sets of looper rollers 41, 42, the upper rolle...

Abstract

An exit unit of rolling mill for implementing the constant-speed rolling is composed of a tension roller set, a looper, another tension roller set and a coiling machine, which are serially linked.

Description

(1) Technical field [0001] The invention relates to the technology of a strip rolling production line, in particular to an outlet device of a rolling mill. (2) Background technology [0002] Strip rolling has gradually developed from the earliest sheet rolling to coil rolling and finally to continuous rolling. The emergence of continuous rolling mills has realized endless rolling, eliminating the need for low-speed, unstable strip threading and tailing processes, not only greatly increasing the average rolling speed, improving the productivity of the rolling process, but also reducing the thickness of the head and tail and the thickness of the plate. The over-tolerance length of the shape improves the product quality and yield. [0003] Continuous rolling can be divided into three forms. The first is a single full continuous rolling mill, which is to add welding machines, loopers and other equipment in front of the conventional cold rolling mill to make cold-rolled strips u...
