It is a kind of equipment often used in the production process of steel strips. At present, in the production of cold-rolled reversible rolling mills, steel coils are mostly used. production methods. Since the steel strip has no tension in the initial and head-to-tail stages, the problem is that the head and tail of each steel coil cannot be rolled, and the finished product process needs to be cut off to form the head and core, which cannot be reused. It becomes a waste product, causing the yield rate of reversing rolling mill and cold rolling ratio to be about 5 percentage points lower than the yield rate, and the cost is not competitive. For this reason, some cold rolling mills open the outer ring of the steel coil on the uncoiler and directly weld the coil core manually. Every time it needs to stop work, but the production efficiency is low, and the welding quality is difficult to guarantee.

Detailed ways

As shown in Figure 1,

A production line for the integrated utilization of winding cores and waste and defective steel coils, including a welding device 1 located in the middle, wherein the welding device 1 adopts a steel strip laser welding machine, and hydraulic shears are provided on the left and right sides of the laser welding machine. It is used for welding between the transverse joints of two steel strips, and is a prior art equipment.

The first pair of neutral rollers 11, the first cross-cut shearing machine 12, the second pair of neutral rollers 13, the three-roller straightening and pinch rollers 14, the swing guide plate platform 15 and The raw material roll uncoiler 16, wherein the raw material roll uncoiler 16 has dual functions of uncoiling and winding through forward and reverse rotation. Among them, the centering vertical roll is used to ensure the centering of the vertical roll before and after (relative to the rolling direction), eliminate the gap between the vertical roll archway, improve the rolling shape of the vertical roll mill and reduce the rolling deviation of the vertical roll. It is a commonly used equipment. The three-roll straightening pinch roller 14 is used to clamp the steel strip, guide and ensure its direction of travel, and carry out preliminary straightening of the steel strip, which is also a common equipment. In addition, the cross-cut shearing machine, swing guide table and raw material roll uncoiler are commonly used equipment and will not be introduced here.

From the other side of the welding device 1, the third pair of neutral rollers 21, the second cross-cut shearing machine 22, the feeding frame 23, the flattening machine 24 and the uncoiling device 25 are sequentially arranged from the inside to the outside. The feed side of the second cross-cutting shearing machine is provided with a length-setting device 26 for auxiliary measurement of the shearing plate size. There is a steel plate collecting device 27, which is used to collect the steel plate material cut off from the coil core.

Wherein, the uncoiling device 25 is a core unwinding box, and the core unwinding box includes a pair of freely rotating ground rollers and a case cover, and the case cover covers the ground rollers and is provided with a steel strip outlet on the side of the case cover seam. The feeding frame 23 is a material frame with rotating rollers, which is used to assist in lifting the steel strip. In addition, the leveling machine and the cross-cut shearing machine are prior art equipment.

The specific process is as follows:

1) First put the core/waste roll into the uncoiling device, and lead it to the second cross-cut shearing machine through the leveler and the feeding rack;

2) The unsuitable part of core/scrap thickness is cut to length by the second cross-cut shearing machine, the unqualified part is cut out, and the part with qualified thickness is sent to the welding device to wait for welding;

3) At the same time, lead the raw material coil to the first cross-cut shearing machine to cut off the head of the steel strip through the uncoiler, guide plate table, three-roller straightening and pinch roller, and then send it to the welding device for welding;
