The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the rolling unit of the short flow process of the X-I of present embodiment H shaped steel comprises vertical universal roughing mill 1, edging mill 2 and the vertical omnipotent finishing mill 3 arranged by roughing-edging-finish-rolling process flow sequence, and described edging mill 2 is the vertical edging mills of two rollers; The roll of described vertical universal roughing mill 1 surrounds the X-shaped rolling groove, and the middle part of described X-shaped rolling groove is the pass of H shaped steel web 4, and the upper and lower of described X-shaped rolling groove is the pass on the H shaped steel edge of a wing 5; The roll surface of two edger rolls of described edging mill 2 is provided with the pass on the rolling H shaped steel edge of a wing 5; The roll of described vertical omnipotent finishing mill 3 surrounds I shape rolling groove, and the middle part of described I shape rolling groove is the pass of H shaped steel web 4, and the upper and lower of described I shape rolling groove is the pass on the H shaped steel edge of a wing 5.
In the present embodiment, described edging mill 2 is one, certainly in different embodiments, and also can be according to two or 3 edging mills 2 of rolling needs while arranged in order, so that the edging pass of each rolling pass is set flexibly.
The operation of rolling of the rolling unit of the short flow process of the X-I of present embodiment H shaped steel is: at first, the vertical placement of rolled blank enters the X-shaped rolling groove of vertical universal roughing mill 1, and the rolled piece cross section is rolled into the X-shaped shape; Then, rolled blank enters limit, the edging mill 2 rolling edge of a wing, the width on the control H shaped steel edge of a wing; At last, rolled blank enters the I shape rolling groove of vertical omnipotent finishing mill 3, and the rolled piece cross section is rolled into I shape, i.e. the H shape of vertical placement.In the operation of rolling, by the rolling shape of product that needs that finally rolls out of roll gap adjustment and reversible reciprocal several passages.
In the present embodiment, described edging mill 2 is the vertical edging mills of two rollers, and equipment cost is low; But when rolling, because the vertical edging mill of two rollers does not reliably support restriction to H shaped steel edge of a wing lateral surface, when the edging drafts is big or during rolling thin-wall shaped steel etc., distortion as shown in Figure 3 appears in the edge of a wing easily.
Therefore in different embodiments, as shown in Figure 2, described edging mill 2 can adopt the omnipotent edging mill of four rollers to replace the vertical edging mill of two rollers, the vertical omnipotent edging mill of four rollers has edger roll 6 and a pair of driven horizontal roller 7 of a pair of band drive unit, edger roll 6 is used for the width on the control H shaped steel edge of a wing, driven horizontal roller 7 mainly plays a part to support the distortion of the restriction edge of a wing, and four rolls constitute edging pass jointly.Adopt the vertical omnipotent edging mill of four rollers can be reciprocal when rolling, by adjusting drafts, the convenient rolling groove size that forms every time demand.The vertical omnipotent edging function of four rollers improves rolling stability, effectively reduces product rolling defect.
The rolling unit of the short flow process of the X-I of present embodiment H shaped steel adopts the rolling unit rolling H of the short flow process of vertical X-I shaped steel, and the advantage that metal is easy to flow when having the X groove rolling, product is easy to moulding can reduce roll wear, improves the roll utilization rate; And the vertical placement of rolled piece is rolling, make cooling water on rolled piece, not accumulate in a large number for a long time, rolled piece each several part cooling velocity is more even, thereby can improve lumber recovery, and reduces energy resource consumption.
As the improvement to present embodiment, described vertical universal roughing mill 1 comprises vertical rolls 8 and two horizontal rolls 9 that driven by rolled piece of two band drive units, and vertical rolls 8 and rolled piece contact area are big, and driving force is big, can guarantee that rolled piece is stable mobile.
As the improvement to present embodiment, described vertical omnipotent finishing mill 3 comprises vertical rolls 10 and two horizontal rolls 11 that driven by rolled piece of two band drive units, the face that the vertical rolls 10 of described vertical omnipotent finishing mill cooperate with the edge of a wing of H shaped steel is taper seat, in concrete enforcement, the angle of taper seat bus and axis is best in 0-10 ° of scope; The taper seat structure is conducive to metal flow, can reduce roll wear and improve the roll utilization rate; Vertical rolls 10 and rolled piece contact area are big simultaneously, and driving force is big, can guarantee that rolled piece is stable mobile.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
