Background technology
In iron scale that stainless steel surfaces produced in when heating or the iron scale that generates when rolling, contain Cr
3O
3With spinelle FeO.Cr
3O
3, black in color is blue or green sometimes usually.In order to improve stainless outward appearance and corrosion resistance, the stainless steel after the processing must carry out acid wash passivation to be handled, and removes oxide layer and iron scale; Make it the bright as silver light that has; And make surface after the processing form one deck to be the oxide-film of main matter with chromium, can not produce the secondary oxygen candle again, reach the passivation purpose; Thereby improve the surface anticorrosion quality of stainless steel products, prolong durability.
Acid washing passivation technology is that the band steel is sent into the stainless steel annealing pickling lines, is reduced through washing lotion.Pickling line length reaches hundreds of rice, and band steel length can reach more than 1,000 meter, must be controlled in certain lateral extent when therefore transmitting with steel, if depart from the unit center line, can cause being with steel to be scrapped or device damage.
The annealing and pickling machine all is equipped with center support system not depart from the unit center line with control band steel.Usually, center support system comprises digital control unit, probe unit, hydrostatic transmission module and correction roller.Probe unit is positioned at correction roller downstream, and band earlier through the correction roller, gets into the probe unit monitoring range again on production line.Digital control unit is analyzed the feedback signal of probe unit, judges whether band departs from the center line of stainless steel annealing pickling machine, offset direction and distance, and sends action command to hydrostatic transmission module, drives the displacement of correction roller, proofreaies and correct the band position.
Prior art goes out to be with side to detect the skew of band steel at the correction roller, and life period is poor between the correction roller corrective action, and rectifying effect is undesirable.And the correction roller is supported by hydraulic stem, along with the perpendicular axes of the center line of stainless steel annealing pickling machine, when band steel malposition; Have certain angle between correction roller in the action and the band, the two is not to contact fully, especially under the situation that the roller action is too frequent and belt steel thickness is thin, tension force is big of rectifying a deviation; Can be with steel to pull the generation oscillatory occurences; The roll surface that causes and rectify a deviation in the opposite direction produces " warpage ", and strip edge portion forms monolateral wave, influences steel product quality.
The utility model content
The technical problem that the utility model will solve provides a kind of centralising device, not only can detect and correct the situation of stainless strip off center line, and the roller vibration that can prevent to rectify a deviation, and avoids the distortion of band limit portion.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of centralising device of stainless steel annealing pickling machine comprises digital control unit, probe unit, hydraulic cylinder, correction roller, support, base, hydraulic stem, slide unit and travelling arm.Digital control unit electrically connects with probe unit and hydraulic cylinder respectively.The correction roll shaft is to the through hole that has circular arc, and the correction roller is located on the support of circular arc through this borehole jack.Base is provided with the guide rail of circular arc, and the radian of hole, support and guide rail is consistent.Be provided with slide unit in the guide rail, slide unit matches with the guide rail shape.Travelling arm is fixedly connected with slide unit.The correction roller flexibly connects through travelling arm and base.One end of hydraulic stem is connected with hydraulic cylinder through rotating shaft.The other end of hydraulic stem is connected with travelling arm.
In preferred embodiment of the utility model, probe unit is positioned at the correction roller upper reaches.
The beneficial effect of the centralising device of the utility model stainless steel annealing pickling machine is: the correction roller drives the lower edge support at hydraulic stem and does the circular arc motion; Compared with prior art; During the band malposition; Angle between correction roller and the band reduces, thereby has weakened the vibration of correction roller, avoids the distortion of band limit portion.

Fig. 2 is the centralising device correction roller of the utility model stainless steel annealing pickling machine and the cross sectional representation of support;
Fig. 3 is the schematic side view of the centralising device correction roller of the utility model stainless steel annealing pickling machine.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the centralising device of the utility model stainless steel annealing pickling machine comprises digital control unit, probe unit, hydraulic cylinder, hydraulic stem, correction roller, support, base and travelling arm.
In order to detect the center of band steel, the utility model has adopted two groups of probe units.First probe unit and second probe unit are installed in the both sides symmetrical with the center of acid-washing stainless steel machine respectively.Each probe unit detects a limit of band steel respectively.Two groups of probe units all are positioned at the forward (FWD) side of correction roller.
Each probe unit comprises signal projector and the signal receiver that is positioned on the same vertical line.Signal can be electromagnetic wave, ultrasonic wave or light wave; Signal is reflected when running into the band steel; Though or penetrate band steel but waveform or intensity and change, produce flux difference with the signal of directly being accepted by signal receiver, flux difference is converted to feedback signal by signal receiver.
The digital control unit and first probe unit and second probe unit electrically connect respectively.Digital control unit is gathered the feedback signal of two groups of signal receivers and is calculated its difference, converses band offset direction and cheap distance.Be symmetrically distributed because two groups of probe units are the centers along the acid-washing stainless steel machine, when band did not have skew, two groups of feedback signals should be identical, and difference is 0.
