Abstract

A kind of flexible long material endless rolling device, belongs to flexible rolling technical field.Including heating unit (1), descaling device (2), the movable welding connection device (3) for possessing traverse moving function, oscillating roller way (4) and milling train (5).Descaling device (2) is located at after heating unit (1), the movable welding connection device (3) for possessing traverse moving function is located at after descaling device (2), oscillating roller way (4) arranges that milling train (5) is arranged in after oscillating roller way (4) close to movable welding connection device (3).Advantage is, it is possible to achieve the endless rolling of long material production line, reaches the effect for improving operating rate of rolling mill, improving lumber recovery, reducing plant maintenance.And it can flexibly switch between endless rolling and single base rolling mode, improve the flexibility of operation, reduce equipment failure rate, improve operating rate.

Description

A kind of flexible long material endless rolling device
Technical field
The utility model belongs to flexible rolling technical field, more particularly to a kind of flexible long material endless rolling device.Can With long material production in realize endless rolling, can improve operating rate of rolling mill, improve machine when yield, improve lumber recovery, reduce set The standby effect safeguarded, and can flexibly switch between endless rolling and single base rolling mode, the flexibility of operation is improved, is dropped Low equipment failure rate, improves operating rate.
Background technology
Endless rolling technique is a kind of technological revolution of long material production, the technology be continuous casting square billet it is heated after by previous piece Steel billet afterbody and latter piece of steel billet head carry out butt welding, form base without a head and send continuous hot-rolling mill to be rolled, exist since in March, 1998 There have been quick development in Tokyo Gao Song factories since coming out.Endless rolling is compared with pair rolling, and production efficiency can improve 12%-16%, production cost reduce 2.5%-3.0%, and for Fixed Length Ratio of Bar close to 100%, recovery rate of iron improves about l%, from Rolled piece attributional analysis, because an only head, can significantly reduce rolling longitudinal size and performance uneven phenomenon.
After domestic production line introduces endless rolling, the great economic benefit that endless rolling process bands are come has been realized rapidly, But it is more demanding due to requirement of the endless rolling technique to billet quality, especially steel billet curvature and end mass, it is difficult to Realize 100% endless rolling, along with the maintenance of external introducing equipment is not in place, cause the welding technique without a head development of the country It is substantially at dead state.The utility model is directed to such case, it is proposed that this flexible endless rolling device and method, leads to The welder that can easily switch between online and offline position is crossed, improves the flexibility of production, reduces the failure rate of equipment And maintenance, ensure operating rate of rolling mill.When can play the great economic benefit of endless rolling and be difficult to realize endless rolling It is preferably minimized its influence to production efficiency.
The content of the invention
The purpose of this utility model is to provide a kind of flexible long material endless rolling device, nothing is applied in long material production line Head rolling mill practice, yield, the effect for improving lumber recovery, reducing plant maintenance when being improved operating rate of rolling mill, improving machine, and It can flexibly switch between endless rolling and single base rolling mode, improve the flexibility of operation, reduce equipment failure rate, improve Operating rate of rolling mill.
The utility model includes heating unit 1, descaling device 2, the movable welding connection device 3 for possessing traverse moving function, swing Roller-way 4 and milling train 5.Descaling device 2 is located at after heating unit 1, and the movable welding connection device 3 for possessing traverse moving function is located at de-scaling After device 2, oscillating roller way 4 is arranged close to movable welding connection device 3, when movable welding connection device 3 works, Mobile welding Device 3 can be moved to the top of oscillating roller way 4, and moving the corresponding part roller-way 4 of welder 3 at this time will be by Mobile welding Device 3 substitutes, and milling train 5 is arranged in after oscillating roller way 4.The horizontal stroke of the packaged type welder 3 for possessing traverse moving function Telephone-moving structure is hydraulic pressure, pneumatically or electrically mechanism.
The steel billet that long material production line uses is heated to rolling temperature by heating unit 1, then removes surface by descaling device 2 Iron scale.When using endless rolling technique, welder 3 is in online position, by the head of a upper steel billet and next The tail of steel billet is welded, and is formed base feeding milling train 5 without a head and is rolled.When steel billet does not possess endless rolling condition or welder 3 During failure, offline position is moved the device into by the traverse moving function of the device, the single milling train 5 of being sent into of blank rolls.Production line Can flexibly it switch between both of which.
The utility model has the advantage of:Both it can realize endless rolling, obtain endless rolling to enormous benefits, and can be with Flexibly switch between endless rolling and single base rolling, improve the flexibility of operation, reduce equipment failure rate, improve milling train operation Rate.
Brief description of the drawings
Fig. 1 is the overlooking structure figure of the utility model.Wherein:Heating unit 1, descaling device 2, the shifting for possessing traverse moving function Dynamic formula welder 3, oscillating roller way 5, milling train 5.
Embodiment
As shown in Figure 1, a kind of flexible long material endless rolling device and method includes heating unit 1, descaling device 2, possesses Movable welding connection device 3, oscillating roller way 4 and the milling train 5 of traverse moving function.Descaling device 2 is located at after heating unit 1, possesses horizontal stroke The movable welding connection device 3 of shifting function is located at after descaling device 2, and oscillating roller way 4 is arranged close to movable welding connection device 3, When movable welding connection device 3 works, movable welding connection device 3 can be moved to the top of oscillating roller way 4, move welder at this time 3 corresponding part roller-ways 4 will be substituted by movable welding connection device 3, and milling train 5 is arranged in after oscillating roller way 4.
The steel billet that long material production line uses is heated to rolling temperature by heating unit 1, then removes surface by descaling device 2 Iron scale.
When using endless rolling technique, welder 3 is in online position, by the head of a upper steel billet and next steel billet Tail welded, form base without a head and be sent into milling train 5 and roll.
When steel billet does not possess 3 failure of endless rolling condition or welder, this is filled by the traverse moving function of the device Put and be moved to offline position, the single milling train 5 of being sent into of blank rolls.
Production line can flexibly switch between both of which.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, can be to this The technical solution technical scheme is modified or replaced equivalently of utility model, without departing from the objective and model of technical solutions of the utility model Enclose, it should all cover among the right of the utility model.
