Abstract

A method and system are disclosed for receiving a hot rolled bar product from a rolling mill, and for delivering the bar product to a cooling bed. A shear subdivides the bar product into bar segments and alternately directs the bar segments to one or the other of two downstream intermediate paths for continued travel thereon. A switch on each of said intermediate paths alternately directs bar segments traveling thereon to one or the other of two respective downstream delivery paths for continued travel thereon to the cooling bed. Decelerators slow the bar segments traveling along the delivery paths.

The specific embodiment
At first consult Fig. 1 and 2 A-C, show between the last mill stand 10 of a continuously hot rolling bar mill and a traditional transmission cooling bed 12, according to a system of the present invention.Along path P AThe bar product that leaves mill stand 10 is cut apart cutting machine 16 by one then and is subdivided into many rod sections by a series of water tanks 14.The cutting machine 16 of the traditional structure that those skilled in the art are known comprises a switching mechanism, and all rod sections that this mechanism will be segmented alternately cause two downstream intermediate path P B, P CIn one or another.Then, at intermediate path P BOn a switch 18 be used as and alternately Zhu Bangduan caused two downstream transfer path P D, P EIn one or another, and the switch 20 on intermediate path alternately causes all product sections two downstream transfer path P similarly F, P GIn one or another.All cover transfer path P side by side D, P EAnd P F, P GReach all pinch rolls (pinch roll) unit 24,26 by a series of water tanks 22, center on partly by two 180 ° of relative curve C then 1, C 2A formed side ring (side loop).Curve C 1Partly form by a removable boot segment 28.Side ring comprises all water tanks 30.In curve C 2The place makes two cover transfer path P D, P EAnd P F, P GVertical alignment continues to arrive all pinch roll unit 32,34 then, readvances cooling bed 12.
Consult Fig. 3, it will be appreciated that: use all individual layer guidance units (the single tier guide unit) 36,38 have the guiding tube 40 that separates along side direction along laterally disposed and all cover transfer path P vertical off setting D, P EAnd P F, P GGuiding Zhu Bangduan, and when two cover transfer path vertical alignments, use double-deck groove unit (two tier throughunit) 42 guiding Zhu Bangduan.
As can being clear that from Figure 4 and 5, pinch roll unit 32 has respectively and transfer path P GAnd P FTwo cover pinch rolls 44,46 of alignment, and pinch roll unit 34 also has respectively and transfer path P DAnd P ETwo cover pinch rolls 48,50 of alignment.Each overlaps pinch roll and passes through power transmission shaft 52, a gear-box 54 and drive motor 56 individually by transmission.With all pinch rolls of selecting of speed drive, be used for all rod sections that frictionally are clamped between all rollers are implemented suitable deceleration.
Pinch roll unit 24,26 has similar structures, but arranges differently slightly, is used for aliging with all path of navigation vertical interlaced with horizontally set.
Now, with reference to leave last mill stand 10 with one of 60 meter per seconds higher speed with temperature serve as that about 950-1050 ℃-8.0 mm dia bar products are sent to a cooling bed situation, further narrate an example operation of said system.Stop the work of all water tanks 14, make the bar product freely by arriving cutting machine 16, bar is subdivided into continuous many rod sections there.The switching mechanism of cutting machine causes intermediate path P with Zhu Bangduan B, P CThen, in path P BOn all rod sections of advancing alternately guided to transfer path P by switch 18 D, P E, and, at intermediate path P COn all rod sections of advancing alternately guided to transfer path P by switch 20 equally F, P G
Then, pinch roll unit 24 and 26 work begin to make Zhu Bangduan to decelerate to a lower midrange speed of about 30 meter per seconds.28 guiding Zhu Bangduan walk around side ring and pass through all water tanks 30 by the curve boot segment.Air line distance between pinch roll unit 24,26 and all water tanks 30 is preferably less than the length of Zhu Bangduan.Like this, all rod sections with one favourable than low velocity enter all water tanks 30 and simultaneously pinch roll unit 24,26 still act on them.All water tank work is cooled to about 500-600 ℃ with Zhu Bangduan, and they enter curve C then 2Pinch roll unit 32,34 is worked then, further Zhu Bangduan is decelerated to a speed of about 3-8 meter per second, and this speed allows Zhu Bangduan to slide up to stopping at cooling bed 12 upstream end place.From here, connecting gear (not shown) work, all rod sections cooling bedly go up and cross cooling bed along laterally moving to, and they are subjected to further cooling there, arrive this transmission side then.
Particularly importantly provide a plurality of transfer paths for the present invention, so that it is linked together with a plurality of transfer paths that are used for the product by switch 18,20 to leave continuous all rod sections of cutting apart cutting machine 16.In above-mentioned example, continuous all rod sections will be accepted following order repeatedly:
Intermediate path Transfer path
P B D D
P C D F
P B D E
P C P G
Only per the 4th rod section is directed to and transmits route, is useful on adequate time and the space that a rod section reduces speed now thereby made along article one transfer path before accepting next rod section.
As shown in Figure 6, when handling, by replacing curve boot segments 28 to reconfigure this system with always tapered guide section 58 than the slow bar product of major diameter.Like this with regard to bypass at half-turn place C 1With C 2Between the side ring that forms.
In this mode of operation, will allow in all water tanks 22, to cool off than the post intensity of the raising of major diameter product and the slower transfer rate of milling train.To carry out two stage deceleration then, beginning is by pinch roll unit 24,26 with then by pinch roll unit 32,34 decelerations.
Therefore, it will be appreciated that: the adaptability of system of the present invention is extremely strong, and it can be with the broad range of a favourable high tonnage rate adaptation product.By freely carrying out initial deceleration by pinch roll 24,26 by all water tanks 22 with before in water tank 30, cooling off, can with the higher milling train transfer rate of about 60 to 32 meter per seconds for example handle those 6.35 to 12.0 mm dia scopes than the minor diameter product.Diameter surpass 12.0 millimeters and to leave can in all water tanks 22, cooling off of milling train than jogging speed below about 30 meter per seconds than the major diameter product, be subjected to the deceleration of pinch roll unit 24,26 then.
