Abstract
The invention relates to a multi-channel S-shaped large repeater production line for producing high-speed wires, and a process for rolling the large repeater. A multi-channel S-shaped turn-back arrangement is adopted in the technological line between an intermediate train and a laying head to arrange high-speed area processing facilities such as a pre-finishing mill group, a finishing mill group, a reducing-sizing mill, a pair of high-speed flying shears and an intervenient water tank, a uniform temperature section and the like on an S-shaped large repeater rolling line; A, B and C channels with different rolling line lengths are used for producing high-speed wire products with different specifications respectively; and a steel-dividing track switch is adopted to control the rolling line. The multi-channel S-shaped large repeater production line can shorten the length of a main factory building, save construction lands, reduce the area of the main factory building, reduce the construction investment, avoid surface scuffing of rolling piece and improve the product quality, and has stable and reliable operation and large production flexibility; besides, all devices in a high-speed area can be overhauled under a condition of not stopping production in the process of producing different specifications, thus the operating rate of a rolling mill is improved.
Description
Technical field
The invention belongs to iron and steel metallurgical industry stress metal processing high-speed wire production line and rolling mill practice method thereof.
Background technology
For improving the high-speed rod mechanical performance of products, the developing direction of Modern High-Speed wire production technology is to adopt the zerolling technology.Metal under 750～850 ℃ low-temperature condition in the end 2～4 passages finish distortion, make metal obtain thinner more uniform grain structure, to improve the structure property of metal.Some steel grade can be accomplished to exempt from annealing or be reduced heat treatment time, with drawing property, the cold forming capability of raising steel, or the intensity and the toughness of raising metal.High-speed wire production line has the high characteristics of mill speed, and the highest mill speed reaches 105～120 meter per seconds.Metal produces very high temperature rise in the high-speed rolling process, for reaching the purpose of zerolling, the Modern High-Speed wire rod production line goes out the product that finished product changes all specifications into by 10 original finishing mills and all goes out finished product from 4 reducing sizing mill groups, and promptly metal is finished the distortion of last 4 passages in the reducing sizing mill group under low-temperature condition.For the rolled piece temperature being reduced to the uniformity of required temperature of zerolling and assurance rolled piece section temperature, all be provided with water-cooled case and sufficiently long samming section between pre-finishing mill group in rolling line, mm finishing mill unit, the reducing sizing mill group, therefore rolling line is very long, the workshop floor space is very big, high speed equipment such as pre-finishing mill group, mm finishing mill unit, reducing sizing mill group, high-speed flying shear must could overhaul when stopping production simultaneously, influence the performance of milling equipment ability.
Part Modern High-Speed wire rod production line has adopted annular big repeater to arrange both at home and abroad at present, water tank between pre-finishing mill group and mm finishing mill unit and samming section adopt the big repeater of annular, main building length is shortened significantly, the flexibility of producing increases, part high-speed equipments such as mm finishing mill unit can overhaul under the state that does not stop production, but also have the following disadvantages: the one, the big repeater of the annular between pre-finishing mill group and the finishing mill has adopted arc guide barrel, rolled piece easily produces surface tear in arc guide barrel, unfavorable to product quality, arc guide barrel wearing and tearing simultaneously are big, need often to change, influence is produced, and spare parts consumption is big; The 2nd, pre-finishing mill group and reducing sizing mill group must stop production to overhaul.
Summary of the invention
The present invention aims to provide a kind of high-speed wire production line and rolling mill practice method thereof that overcomes above-mentioned prior art weak point, the technical scheme of dealing with problems is: production line adopts multi-channel S-shaped big repeater to arrange, process route between middle milling train group and Laying head adopts the multi-channel S-shaped layout of turning back, and pre-finishing mill group, mm finishing mill unit, reducing sizing mill group, high-speed flying shear and high velocity process equipments such as water tank therebetween, samming section are arranged on the rolling route of the big repeater of S shape.The rolling mill practice flow process is divided A, B, three different passages of rolling line length of C, is respectively applied for the high-speed rod product of producing different size, adopts and divides steel track switch to come the controlled rolling route:
(1) C-channel: between middle milling train group and Laying head, form the rolling route of big S shape, on the big rolling route of the big repeater of S shape, be furnished with all high-speed equipments such as horizontal kink I, flying shear I, pre-finishing mill group, water tank II, samming section, horizontal kink III, mm finishing mill unit, water tank III, reducing sizing mill group, water tank IV successively, two 180 ° the horizontal kink of an employing of turning back, the rolled piece that is used to lead changes direction of travel and regulates tension force between the milling train, makes rolled piece accomplish tension free rolling between two groups of milling trains.The C-channel circuit is the longest, also is the full layout of all devices on the big repeater of S shape, is used to produce the high-speed rod product of small dimension.
(2) B passage: throw mm finishing mill unit away, rolled piece is established the B passage between pre-finishing mill group and reducing sizing mill group, forms the rolling route of little S shape between middle milling train group and Laying head, is used to produce the high-speed rod product of medium specification.
(3) A channel: throw big repeater of S shape and the whole high-speed equipments that are arranged on the rolling route of the big repeater of S shape away, between middle milling train group and Laying head, establish A channel, be used to produce the high-speed rod product of big specification, rolled piece through in the milling train group directly after the Laying head rolling, go out finished product after rolling.
Marked improvement effect of the present invention is:
(1) multi-channel S-shaped big repeater production line can shorten about 160 meters of factory building length, has saved a large amount of construction lands and the area that has reduced main building, and construction investment reduces significantly.
(2) the big repeater rolling line of the S shape horizontal kink of whole employings of turning back has substituted crooked guide groove, and the surface tear of having avoided rolled piece to produce at arc guide barrel is favourable to product quality.
(3) the big repeater of the S shape horizontal kink of turning back has substituted upright kink before the pre-finish rolling, and simple in structure, the cover amount is controlled easily, do not have mechanical accident, guaranteed between pre-finishing mill group and the middle milling train group 100% tension free rolling, technology accident is few, reduce rolling defect, improved product quality.
(4) adopted the multichannel technology arrangement, the product of different size enters Laying head by A, B, C-channel respectively, the flexibility of producing is very big, the all equipment of high velocity is when producing different size, high speed equipment such as pre-finishing mill group, mm finishing mill unit, reducing sizing mill group, high-speed flying shear can overhaul under situation about not stopping production, and can significantly improve operating rate of rolling mill.
Any process equipment accident that causes because of multi-channel S-shaped big repeater did not take place in (5) stable and reliable operation after the operation.
