Abstract

In a system for subdividing hot rolled product lengths being delivered from a rolling mill along a first path, a first switch acts in concert with a first shear to subdivide each product length traveling along the first path into successive segments including a front end segment, a plurality of intermediate segments, and a tail end segment, and to alternately deliver the successive segments to one or the other of two adjacent downstream second paths leading to a cooling bed. Second switches on the second paths are selectively adjustable between first positions allowing the intermediate segments to continue along the second paths, and second positions diverting the front and tail end segments from the second paths to third paths. A second shear chops the front and tail end segments moving along the third paths into scrap pieces.

Description

The system and method for segmentation hot-rolled product length

The cross reference of related application

The application requires in the temporary patent application No.60/564 of application on April 21st, 2004,067 priority.

Technical field

The present invention relates to the milling train of producing hot rolled long products widely, for example, bar, an excellent class, and relate in particular to the improvement system that is provided for segmenting this series products, qualified user's length is delivered to cold bed, and makes underproof front end and end turn to scrap chopper.

Background technology

The legacy system of the above-mentioned type is usually directed to make hot-rolled product laterally to be diverted to another path from a path, and this is usually by carrying out with switching device shifters that works such as flying shears.Yet for some product, particularly those have the hardness of enhancing, and it is problematic that the action outside underproof front end and the terminal less lateral duction can prove, and causes the generation of waste material and the interruption of rolling process.

Summary of the invention

According to the present invention, the hot-rolled product length of coming out along first path from milling train is directed to first switching device shifter that works with first cutter one so that each product length is subdivided into continuous section, comprises a front end rigion, a plurality of interlude and an end segment.Continuous segment alternately is delivered to second path in downstream of two vicinities one or another from first cutter.Second switching device shifter in second path can optionally be adjusted between the primary importance and the second place, this primary importance allows interlude to proceed to the cold bed in downstream along second path, this second place with front end or end segment from second route turning to Third Road the footpath.Second path is disposed between the Third Road footpath.Front end and end segment that second cutter is used for directly moving along Third Road are cut into the waste material length that is passed to waste material container.

Because second path is disposed between the Third Road footpath, thereby minimize front end and terminal deviation by second switching device shifter.

Now these and other feature and advantage of the present invention will be described in more detail in conjunction with the accompanying drawings; Wherein:

The specific embodiment

At first with reference to the schematic diagram of figure 1 and Fig. 2, shown system 10 according to the present invention is in a position along the most last roll stand RS and the roll line " * " between the cold bed CB of milling train.

The first switching device shifter SW ₁With the first cutter SH ₁Operate together product length is subdivided into continuous section, comprise front end rigion, interlude and end segment.Interlude is included in the metallurgical qualified user's length that, and is scheduled to be passed to cold bed.According to the type of product to be produced, because the cooling of inadequate upstream, front end rigion may be underproof on metallurgy.End segment is shorter than the user's length that requires usually.From cutter SH ₁The continuous segment that comes out alternately is accepted at two path A, the B in contiguous downstream.

The segmentation section of moving along path A is directed to the second switching device shifter SW ₂, this second switching device shifter can be adjusted to and allow qualified interlude to continue or make front end and end segment deflect into a different path C along path A ₁The segmentation section that moves along path B similarly is directed to the 3rd switching device shifter SW ₃, the 3rd switching device shifter also can be adjusted to and allow qualified interlude to continue or make front end and end segment deflect into a different path C along path B ₂

Scrap chopper SH ₂Be positioned at switching device shifter SW ₂, SW ₃The downstream.From Fig. 2, can find out cutter SH best ₂Have two groups of shear-blade B that move together ₁, B ₁And B ₂, B ₂, these two groups of blades are arranged in path C respectively ₁, C ₂On.Path A, B freely pass between the set of blades of the lateral spacing of scrap chopper.At cutter SH ₂The downstream, path C ₁, C ₂Lead to waste material container CR and path A, B proceeds to cold bed CB.

With reference to figure 3, in the order of demonstration, cutter SH ₁With being used for the steel billet length from product that the most last roll stand RS transmits is subdivided at the short front end rigion L of metallurgy for substandard product ₁, have an interlude L of qualified user's length usually ₂-L ₅And also has underproof short end segment L usually ₆

Switching device shifter SW then ₂, SW ₃Handle these sections shown in the following Table A.

Table A

Product length	The path			Cutter SH ₂	Cold bed CB	Waste material container CR

L ₄	L ₃	×			×				×			×
L ₄	L ₅	×			×				×			×
L ₆	L ₅	×			×		×	×		×		×

Aforementioned order only is illustrative and will changes according to the type of processed product that user's length will be segmented therein, or the like.

Can see the more detailed description of switching device shifter of the present invention and cutter with reference to figure 4-6.From Fig. 4, can see switching device shifter SW ₁Comprise that an assembling is used for the guide pipe 12 around pivot 14 motions, and rotor ground is adjusted by bucket cylinder unit 16 cutter SH is passed in the product transmission ₁Arrive path A, B.Cutter SH ₁Can be to well known to a person skilled in the art conventional design.

Inlet guide spare 18 guiding are passed to corresponding switching device shifter SW along path A, B ₂, SW ₃Section, each fitted to be around pivot 20 motion.Switching device shifter SW ₂Can adjust allowing qualified interlude to proceed to cold bed by bucket cylinder unit 22, or make underproof front end and end segment turning path C along path A ₁Switching device shifter SW ₃Can be similarly adjust allowing qualified interlude to continue, or alternatively, make underproof front end and end segment turning path C along path B by bucket cylinder unit 24 ₂

From Fig. 5 and Fig. 6 as can be seen, scrap chopper SH ₂Has the parallel axes 26 that supports the gear 28 that is meshed.Lower shaft 26 drives by motor 30 (as shown in Figure 1).The outside jag of axle supports laterally spaced coacting paired shear-blade B ₁, B ₁And B ₂, B ₂, these blades are arranged in path C respectively ₁, C ₂On.Guider 32 is along the path A between the cropping cut blade, the B product section that leads.

Retouch layout on having, switching device shifter SW ₂, SW ₃Only need pivot to turn over low-angle so that the product end segment deflects into their turning path C separately from path A, B ₁, C ₂In this way, the front end of hard relatively product and end segment, for example, the section that those have than major diameter and/or lower temperature can not have waste material risk ground to handle.
