Abstract
A device for changing position of web plate (ST) in swage steel flange profile when rolling it on rolling mill equipment having horizontal rollers (HO, HU). The vertical position in the horizontal central plane of the roll gap (WSP) is formed by the horizontal rollers. The two upper and lower horizontal rollers (HO, HU) are cooperated with each other and run independently, and can align an edge web plate of the flange of the swage steel flange profile transported on a horizontal convey device. A profile-measuring device is arranged in front of the rolling mill for determining the position of the web plate (ST) of the flange profile (FP) lying on a horizontal conveyor (R). The measurement signals are sent to a computer device which produces the position values for the screw-down gears of the upper and lower horizontal rollers (HO, HU) to align the roll gap (WSP) formed by these on the horizontal central plane (M-M) of the profile (FP).

The present invention relates to a kind of device, be used for when the rolling-mill housing layout is rolling, changing the position of shaped steel flange section median ventral plate, this milling train has horizontal roller, wherein, the upright position of the horizontal central plane of the roll gap that constitutes by horizontal roller, by the right mutual harmony of horizontal roller up and down of horizontal roll, motion adjusted independently, aligning lies in and sends on the horizontal transmission device, the edge of a wing that has shaped steel-flange section to one of the web at edge.
When rolling this shaped steel section bar, the central plane of section bar web should be at the center between two edges, the edge of a wing, and the outside can not exceed this center.The universal frame that is used for rolling this section bar has edger roll right in the both sides of whole rolled piece of process, whole above the rolled piece and below have horizontal roll right, it is arranged on the common vertical plane.Owing to adopt this omnipotent roll stand rolling, no matter be when adjusting roll gap or during rolling, all will cause damaging, this is because of for example web position of H section bar, that is to say, the longitudinal median plane of its level, can not be all the time with edge, following top flange that section bar keeps flat between tortuous horizontal central plane consistent, but be offset up and down with respect to this plane.This web position that is called the web degree of eccentricity at first is because different flange widths produces, in other words, because the different distance of lower flange longitudinal edge and top flange longitudinal edge generally is to measure the edge of a wing by edger roll to begin during perhaps owing to the rolling H section bar.At this moment, section bar is at first measured on the outside on the edge of a wing by edger roll, is just measured on the inboard on the edge of a wing and web by horizontal roller then, and the result contacts the deformed area that horizontal roller and the edge of a wing and web formation are longer than in the deformed area that constitutes by edger roll with the edge of a wing.
Except the horizontal roller of its diameter greater than the edger roll diameter used in suggestion, by some resize ratio between the control roll, influence the bite force of these rolls to the web or the edge of a wing, thereby react on the outer center (DE-AS 1,960 891) of web, in addition, also have a large amount of suggestions open, but section bar aim at roll gap (DE-OS 2 457 217) by means of the guider of side direction and Height Adjustment or place adjustable height and can rotating roller-way on to import roll gap.This working method also must influence the web position of outlet side.Therefore, must spend technically and very highly determine rotary position and/or lifting position or down position, so that obtain satisfied web center.In addition, web position also is subjected to the influence of roller diameter.The roll wear that particularly rolling operating period produces can not for example pass through the motor line of engagement coupling of lower roll exactly, but can only compensate approx by means of annex.Do not possess the desired accuracy in web center as long as finish rolling section bar, these measures must be constantly repeatedly.The described suggestion of at first mentioning costs a lot of money technically, and can only in limited scope, use, and other described suggestions of mentioning cost a lot of money equally technically, need operating personnel to have rich experiences in addition, in this case, even now is paid, and but usually can not get accurate effect.
The objective of the invention is to, a kind of device is provided,, produce having more high-precision web position control corresponding influence though the bigger technology spending of its same requirement is using under modern frame manufacturing and the control technology situation.
From a suggestion, it is flange section misalignment roll gap, but will aim at the flange section that sends by this roll gap that horizontal roller constitutes, promptly having mutual tuning independent adjustment of predesignating the size horizontal roller respectively by two moves, on desirable upright position, constitute this roll gap (JP-AS 59-193701), this purpose is achieved thus, promptly in this rolling-mill housing front, arrange a section bar measurement mechanism of determining to lie in the flange section median ventral plate position on the horizontal transmission device, its measuring-signal sends a calculation element to, for the adjusting device of horizontal roller up and down produces adjusted value, the roll gap that is used for being made of these rolls is aimed at the central plane of the level that is sent to the shaped steel-flange section on the roll gap.
As the present invention further provide, in this rolling-mill housing back, arrange another definite section bar measurement mechanism from shaped steel-flange section median ventral plate position that roll gap comes out, its measuring-signal sends a calculation element to, for the adjusting device of other rolling-mill housing of being arranged in this rolling-mill housing back produces adjusted value, rectification is adjusted in the variation that is used for web position that in front rolling-mill housing is obtained.
Aim at roll gap for the shaped steel-flange section pre-control that will keep flat, the horizontal transmission device can be adjusted height.In addition, there is this possibility according to the present invention, but when in inverse operation, carrying out the rolling-mill housing layout, the measuring-signal that produces by one or several section bar measurement mechanisms, being used for by calculation element is the variation that one of rolling direction calculates web position, and calculates the adjustment rectification of roll gap for another rolling direction.
The present invention can use under the modern rolling-mill housing situation, preferably utilize fast adjusting device adjustable under load and section bar measurement mechanism and these to handle the rearmounted calculation element of the numerical value of carrying according to Mathematical Modeling, change the web position in shaped steel-flange section, and the position that control adjustment is obtained on other rolls.It also can be with continous way or reversible operation roll configuration, and compact mill unit for example uses in case of necessity from the rolled piece to the rolled piece, and is not need connect this device all the time during rolled piece by the gross is rolling all the time.The adjusting device of motor operation or eccentric in addition the adjustment can be used under certain condition equally.
Now the present invention is elaborated by the embodiment that is introduced in the accompanying drawing.Accompanying drawing is depicted as:
The roll of Fig. 1 and a kind of horizontal frames of Fig. 2 and shaped steel-flange section
As can be seen from Figure 1, the last horizontal roller HO that has edger roll VW universal frame that does not illustrate and following horizontal roller HU, the roll gap WSP of shaped steel-flange section FP that formation sends along the arrow P direction.The limit of this shaped steel-its lower flange of flange section FP FRU lies on the roller R of roller-way.The web ST of shaped steel-flange section FP is according to the rolled form of front, have horizontal center M-M, here make progress, to the skew of the direction of limit, top flange FRO, the result from upper limb rim FRO to horizonal web plate center M-M apart from d1 less than to bottom wing rim FRU apart from d2.Last horizontal roller HO and following horizontal roller HU are present, arrive at shaped steel-flange section FP before the roll gap WSP of two rolls formations, from the position that for example dotted line is arranged, move in opposite directions by means of its unshowned adjusting device, and constitute roll gap WSP at this moment by same unshowned form measuring instrument and calculation element control, it moves downwards like this relative to the central plane M-M of level, make web ST after entering this roll gap WSP, as from shown in Figure 2, its position is moved, wherein the upper limb rim FRO of shaped steel-flange section FP and bottom wing rim FRU's is identical with d2 ' size apart from d1 ', and the result has reached desirable web center.
