Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

When the finishing mill group, the reducing mill group and the sizing mill group adopt centralized transmission, the finishing mill group, the reducing mill group and the sizing mill group are limited by a centralized transmission structure, the rolling speeds of the finishing mill, the reducing mill and the sizing mill are difficult to independently adjust, the adjustment flexibility is lacked, and the requirements of different wire rods on different rolling speeds are difficult to meet. When the finishing mill, the reducing mill and the sizing mill are all independently adjusted, on one hand, the number of the driving devices is increased, and the investment cost is increased; on the other hand, when all the rolling mills adopt independent adjustment, speed errors exist in the middle of the operation process of the driving devices among the rolling mills, and further when a plurality of rolling mills are arranged, the speed errors are gradually superposed and act on the wire rods, so that the control of the production quality of the wire rods is not facilitated. The application provides a high-speed wire rod production system mainly used solves the rolling speed control problem of rolling mill.

Referring to fig. 1 to 7, in an embodiment of the present invention, a high-speed wire rod production system is provided, including: sequentially setting: the finishing mill group 1 comprises a plurality of groups of finishing modules 11 arranged in an array manner and first driving devices 12 arranged on the finishing modules 11, wherein the first driving devices 12 are used for driving the corresponding finishing modules 11; the reducing machine set 2 comprises at least one group of reducing modules 21 and a second driving device 22 arranged on the reducing modules 21, wherein the second driving device 22 is used for driving the corresponding reducing modules 21; sizing unit 3, sizing unit 3 includes at least a set of sizing module 31 and sets up third drive arrangement 32 on sizing module 31, third drive arrangement 32 is used for the drive to correspond sizing module 31.

On the whole, this application when high-speed wire rod production system uses, carry out the finish rolling operation to high-speed wire rod through finishing mill group 1, rethread reducing unit 2 reduces the diameter operation to high-speed wire rod, carries out the sizing operation to high-speed wire rod through sizing unit 3 at last. The high-speed wire rod can be processed into a required shape and size through the finishing mill group 1, the reducing mill group 2 and the sizing mill group 3. Specifically, four groups of finish rolling modules 11 can be arranged in the finishing mill group 1, a group of reducing modules 21 can be arranged in the reducing mill group 2, and a group of sizing modules 31 can be arranged in the sizing mill group 3. Of course, the designer may also adjust the number of the finishing modules 1, the reducing modules 21, and the sizing modules 31 as needed, which is only illustrated here, and the other setting manners are not limited.

Because the high-speed wire rods can deform among the units, the rolling speed of each unit to the high-speed wire rods is different. In order to obtain better rolling quality of the high-speed wire rod, the rolling speed among the units needs to be adjusted, so that the rolling speed among the units is more matched to increase the rolling quality of the high-speed wire rod. The designer can adjust the rolling speed of each unit according to the rolling process, and the method is not limited herein.

Specifically, referring to fig. 1 to 7, the high-speed wire production system may include: a finishing mill group 1; a reducing mill unit 2; a sizing unit 3.

In this embodiment, since the high-speed wire rod is elongated due to deformation during the finish rolling, in order to roll the high-speed wire rod better, the rolling speed of each finish rolling module 11 needs to be controlled by the first driving device 12 provided on the finish rolling modules 11, so that the rolling speed of the 4 groups of finish rolling modules 11 matches the production needs of the high-speed wire rod.

Wherein, when the high-speed wire rod is rolled, the wire rod is extended to increase the linear velocity, so that the rolling speed of the finish rolling module 11 needs to be correspondingly increased gradually. The designer can prestore the corresponding mathematical relationship between the elongation in the high-speed wire rod rolling process and the rolling speed required by the finish rolling module 11. When rolling a high-speed wire rod, the operator can control the rolling speed of the finishing module 11 by means of the first drive 12 according to the aforementioned mathematical relationship.

When the high-speed wire rod passes through the partial finishing modules 11, the first driving devices 12 are arranged on the finishing modules 11, so that the empty finishing modules 11 can be closed independently in advance without adjusting the rolling speed, the production preparation time can be saved, the operation efficiency is improved, and the advantage is that the centralized transmission is not adopted.
