Description
Technical field
The present invention relates to the using method of the shape sensing roller in the processing line of metal strap.
Background technology
Shown in Japanese kokai publication sho 54-68283 communique in the past, in the processing line of metal strap, the shape sensing roller of having assembled load detection sensor on width is contacted with metal strap, measure the tension distribution of the width of metal strap.Particularly, in cold-rolling mill, calculate the shape of metal strap based on this, and be controlled to shape as target.
About this shape sensing roller, for example open that clear 62-167109 communique and Japan are real to open in the flat 1-132944 communique openly in that Japan is real, be mode as shown in Figure 1, possess sensor shown in Figure 2.And, between roll body 1 and sensor wrap housing 3,, be provided with tens of microns gap in order to block load from roll body.
But, in the processing line of metal strap, can't avoid attached to the iron powder on metal strap surface or oil attached on the shape sensing roller, because this attachment enters the gap of sensor as the aforementioned, the sensitivity of sensor reduces, and shows the shape different with the true form of metal strap, therefore, in the roll mill of controlling based on this, the situation of the sheet material that mostly occurs fracture.In addition,, be necessary to exchange shape sensing roller, can cause and handle the bigger decline of line efficient in order to break away from this state.
As solution to the problems described above, consider the method for cleaning in the operation.For example, in No. 297177 communique of Japan Patent following formation being disclosed: water is sprayed on the shape sensing roller, and is judged as when having adhered to dirt according to detected result, contact brush again and remove deposit.
Particularly, at stainless steel or electromagnetic steel plate etc., after being reached a high temperature, the temperature of metal strap carries out when cold rolling, inevitable shape sensing roller also has temperature to a certain degree to rise, at this moment, owing to rolling rotten (polymerization materialization) or the evaporation of moisture with oil adhered, be blocked in the gap of sensor, the sensitivity deterioration of sensor is very fast as can be known.
As ways of addressing this issue, consider the method for cooling shape sensing roller, but because shape sensing roller has from the wiring of sensor etc., therefore, the complexity with the method for cold-producing medium by roll inside becomes structure can not adopt.Therefore, as the aforementioned shown in No. 2971177 communique of Japan Patent, consider the method for water spray cooling, but because the high speed of in recent years processing line, the measuring equipment that the water of spraying splashes to periphery exerts an influence, and, if spray to cooling off the water of sufficient amount, can arrive the contact-making surface of shape sensing roller and metal strap, shape sensing roller slides, and can not detect shape accurately.Its result causes the sheet material fracture.
Summary of the invention
The objective of the invention is to, a kind of method of using shape sensing roller is provided,, remove above-mentioned problem, can use shape sensing roller steadily in the long term by in operation, cooling off, clean shape sensing roller all the time.
The present invention makes for solving above-mentioned problem, and its main points are as follows.
(1) a kind of using method of metal strap shape sensing roller, on the almost whole width of the shape sensing roller of metal strap cold-rolling mill, in operation often all the time from outer jet water, and make scraper plate contact compare with position than injection water, more close outlet side on the roll direction of rotation contacts scraper plate.
(2) as the using method of (1) described metal strap shape sensing roller, wherein, cold-rolling mill is reverse roll line (リ バ one a ス ラ イ Application), and the input side on the more close roll direction of rotation than the position of injection water and the position of outlet side are provided with 2 scraper plates.
(3) as the using method of the shape sensing roller of (1) or (2) described metal strap, wherein, the maximum temperature of the band steel in rolling is 100～500 ℃.
By the present invention, it is unusual to have eliminated the caused detection of adhering of foreign matter in the sensor gap of shape sensing roller, does not need the exchange of shape sensing roller thus, and about 1/10th before sheet material fracture incidence becomes can significantly be enhanced productivity.

The specific embodiment
The present invention proposes in order to address the above problem, and by outer jet water, contacts with the outlet side of roll direction of rotation by the scraper plate that makes setting in operation, and roll is cooled to about 200 ℃ and cleaning.
Fig. 3 is the side view of explanation using method of the present invention.In the reverse roll line of metal strap, be provided with roll mill, local derviation roll, be provided with shower nozzle, right rotation in the bottom that is arranged at shape sensing roller therebetween with scraper plate, anticlockwise scraper plate.For this shape sensing roller 1,, remove water by scraper plate 7 by shower nozzle 8 injection waters.
When metal strap was positioned at the top of shape sensing roller, the shower nozzle of injection water was arranged on the bottom of shape sensing roller, and scraper plate is arranged on from the outlet side of nozzle position to the roll direction of rotation.
Here, be in the series connection roll mill of a direction or the roll mill of series-operation line etc. in direction of rotation, preferably 1 scraper plate is set, but in direction of rotation was two-way reverse roll line, scraper plate was provided with 2 at input side and outlet side at the direction of rotation outlet side.At this moment, during right rotation as shown in Figure 4, turn round as illustrated in fig. 5 during anticlockwise.
By this cooling, cleaning performance, the situation of iron powder or wet goods being invaded the gap on shape sensing roller surface is suppressed at bottom line, prevents from the material adhesion of invading from can detect shape accurately all the time.
Shower nozzle is arranged to and water can be sprayed on the whole width of roll.The water yield or not particular provisions of hydraulic pressure.Because a spot of water yield also can obtain effect to a certain degree, therefore can suitably determine according to the temperature of shape sensing roller and the outlet capacity that removes of scraper plate.In addition, because shape sensing roller is a high-speed rotary body, the water of removing roller surface with scraper plate fully is impossible, for preventing that sealing splashes or the slip of shape sensing roller, is necessary to make residual water not produce harm by evaporation.Therefore, preferably can control automatically or remote-controlled operation water sprays and stops,, when making the temperature of shape sensing roller drop to below 50 ℃, can stop water so that by scraping plate temperature decline etc.
Cold-producing medium is water preferably, also can divert the cooling fluid of roll mill etc., utilizes as the cooling fluid effective substances.
That scraper plate is arranged in principle is parallel with roll mandrel, and contact on the whole width of roll.But,, therefore be necessary to be arranged on the part that SHAPE DETECTION is not exerted an influence owing to can exert an influence to SHAPE DETECTION according to contact position is different.In the shape sensing roller, but there is the detection position, many places in a circumferential direction, but when some detection positions touch the band steel, but scraper plate is not contacted with other detection position.For example, when there are 9 in test point with 40 ° interval, make the position that 40 ° multiple is arranged to not to be positioned in the position that is provided with of scraper plate.
The material of scraper plate is brush, rubber etc. preferably, and in order SHAPE DETECTION not to be exerted an influence, preferably thickness is smaller or equal to 25mm.In addition, have the mechanism of the face contact power that can adjust breaker roll, in order to make exchange easily, preferably can pull out, assembled construction by the side.And, so long as can obtain the mechanism of effect of the present invention, even utilize the scraper plate of water removal bodies such as roll, compressed air also harmless.
In addition because long more attached to the time of the water on the roll before being removed, cooling effect is good more, so, shower nozzle and scraper plate that the position is set is preferably far away as far as possible.
The present invention particularly to the maximum temperature of band steel be 100～500 ℃, the roll mill that carries out so-called high temperature rolling has effect.Under such situation, shape sensing roller becomes high temperature, causes rolling adhesion with oil, invades in the gap on shape sensing roller surface.The method according to this invention equals 300 ℃ if the temperature of shape sensing roller is remained below, and preferably is lower than to equal 250 ℃, further preferably remains on below 150 ℃ or 100 ℃, can prevent this adhesion.And the maximum temperature of band steel is lower than under the situation that equals 100 ℃, because the influence of the rolling adhesion of using oil etc. is little, uses effect of the present invention and also diminishes.
Embodiment 1
For the shape sensing roller that on the cold-rolling mill of reverse roll line, is provided with, formulated countermeasure as shown in table 1, carry out approximately respectively 3 months work continuously.Evaluation table at that time is shown in the table 1.At this moment, half is hot rolling system for the pact for the treatment of capacity, and the maximum temperature of band steel almost is 400 ℃.

Whether the foreign matter adhesion is arranged in this gap, is that sensor is applied certain load, estimates with the ratio of this load and the detected load of sensor.This is called factor values, obtains with following formula.
The detected load of load ÷ of factor values=apply
This factor values more greater than 1, just represents to have in the gap foreign matter adhesion greater than 1.The factor values of new product and the data of use after 3 months are illustrated among Fig. 6.Use after 3 months, near the core of the sensor that the band steel passes through with high-frequency, factor values significantly rises as can be known.
In countermeasure 1, can not be rolling because the slip of shape sensing roller and water splash, therefore as countermeasure 2, be provided with when anticlockwise scraper plate as the usefulness that dewaters.Its result, only generation is sprayed and is dewatered with scraper plate when anticlockwise, so the rolling possibility that becomes of anticlockwise direction, but as shown in Figure 7, factor values raises.
Further, set up scraper plate, by in bidirectional rolling, produce spraying, and dewater, thus, can in rolling, cool off all the time, clean, rising that as illustrated in fig. 7 can the inhibiting factor value with scraper plate as countermeasure 3.
