Description
Technical field
The present invention relates to a kind of checkout gear field, relate in particular to a kind of device for detection of the position probing of the hot rolled steel plate sheet material by this place/band that is applied to water cooling zone on the iron and steel hot rolling line.
Background technology
At present, each family's steel production enterprise is in its iron and steel hot rolling is produced, be widely used complete iron and steel hot rolling line equipment, one of key component-water cooling zone on this hot rolling line wherein, whether the production that has directly had influence on the whole piece hot rolling line whether working properly of this section is carried out smoothly.
And water cooling zone whether the key of normal operation just be, when hot rolled steel plate sheet material/band (abbreviation strip) operates in this position section, whether its position detecting mechanism can normally move, and the strip position probing of the Hot Line water cooling zone under prior art is divided into following several mode:
1. go out steel plate position at the appointed time by roller-way rotating speed indirect calculation.
But, in actual production, because the roller table surface cooling water has certain lubrication, particularly Wide and Thick Slab, because weight is excessive, be easy to skid after losing the forward thrust of rolling mill roll, cause between the speed of advancement of hot rolled plate and roller table speed and have deviation, its hysteresis is sometimes large, sometimes little, be difficult to quantitative calculating, cause strip position probing deviation very big.
2. use infrared measurement of temperature.
Although infrared measurement of temperature can have position detecting function concurrently, but it can only measure the steel plate of higher temperature, and be subjected to the influence of moisture of current and evaporation larger, be arranged on before the water-cooled entrance more and outlet section after, seldom be arranged in water cooling zone, therefore infrared measurement of temperature is not a kind of detection means that is applicable in water cooling zone.
3. optical-mechanical system.
Although it is effective that grating detects its detections, it is accurate to measure, and expensive, cost is high, and due to its current of water cooling zone itself and water evaporation, and the maintaining of grating has all been caused no small trouble.
4. electric position sensor.
Electric position sensor is not suitable for the use of water cooling zone, and its reason is that the devices such as water cooling zone roller-way, nozzle, steel plate are all metalworks, and electric position sensor can't obtain the signal of telecommunication accurately, therefore directly uses the effect of electric position sensor relatively poor.
In sum, detection means under prior art or expensive or when having caused strip by the water cooling zone on the iron and steel hot rolling line due to the working condition that itself can't adapt to water cooling zone due to its cost, its position is difficult to detect, directly affected the carrying out of subsequent production work, the strip that the detection mistake that occurs when serious can cause is collided mutually, causes industrial accident.
Summary of the invention
Detect in order to solve the water cooling zone on the iron and steel hot rolling line under prior art the variety of problems that the strip position occurs, the invention provides a kind of slab band position detecting device for water cooling zone, be applicable to strip in the position probing of water cooling zone, be particularly useful for because of the excessive Wide and Thick Slab of easily skidding of conducting oneself with dignity.
Concrete structure of the present invention is as described below:
A kind of slab band position detecting device for water cooling zone comprises water cooling zone frame group, and this water-cooled frame group is comprised of the parallel equal column distribution of several roller-ways with the roller-way support, it is characterized in that:

The specific embodiment
Below in conjunction with drawings and Examples, a kind of slab band position detecting device for water cooling zone of the present invention is described further:
Embodiment
As depicted in figs. 1 and 2, a kind of slab band position detecting device for water cooling zone of the present invention, its installation steps are as described below:
1. at first determine the concrete quantity of the slab band position detecting device for water cooling zone of the present invention that needs are installed according to the length of water cooling zone frame group A, in the present embodiment, quantity is 2;
With slab band position detecting device for water cooling zone welded and installed of the present invention on the roller-way support A1 below roller-way A2, and do not affect the position of existing lower water spout; Should note and note herein the nozzle of floatboard 13 over against each sparge pipe 3 of the injection water pipe group 1 of top.
Install and to use.
As depicted in figs. 1 and 2, a kind of slab band position detecting device for water cooling zone of the present invention, it uses step as described below:
1. the signal of the approach switch 8 of each checkout gear is received PLC;
2. when hot rolled strip 15 does not put in place, because the cooling water flow of the sparge pipe 3 of the injection water pipe group 1 of top continues to impact on floatboard 13, under the effect of hydraulic pressure, make the connecting rod 8 of right-hand member press down, the design of lever-like makes the connecting rod perk of left end, because the upper limit movement locus of responding to bolt 14 overlaps with approach switch, what the therefore approach switch 8 of this moment was passed to the PLC control system is " 1 (signal is arranged) " all the time;
And when hot rolled strip arrives the position of slab band position detecting device for water cooling zone of the present invention, because hot rolled strip has blocked the top current, the connecting rod 12 of left end adds that the overall weight of connected induction bolt 14 adds the overall weight of connected floatboard greater than the connecting rod of right-hand member, due to leverage, therefore the connecting rod of left end descends, the connecting rod perk of right-hand member simultaneously, the induction bolt of left end no longer overlaps with approach switch, be that this timer output signal changes, such as " 0/ steel plate is in place " signal.Therefore approach switch provides " 0 (no signal) ".
3. the signal that is drawn by PLC in above-mentioned steps 2 can be revised steel plate current location value, is convenient to carry out predetermined cooling strategy.
4. namely repeat the operation in above-mentioned steps 2 after hot rolled strip 15 passes through.
A kind of slab band position detecting device for water cooling zone of the present invention, its for hot rolled strip after hot rolling, its afterbody leaves milling train, lose when continuing the laggard water cooling zone frame group A of the entering motion of thrust, due to the lubrication of water, hot rolled strip just might skid on roller-way A2, causes the velocity lag that moves ahead of hot rolled plate in roller table speed, especially the larger Wide and Thick Slab of deadweight, its hysteresis is difficult to control.And in the zone of this steam transpiration, general position detecting device is difficult to play effectiveness, and the systems such as grating, laser are not only expensive, and to environment require high.Although therefore slab band position detecting device for water cooling zone of the present invention is simple in structure, but because its detection means and hot rolled strip itself are irrelevant, therefore accurately and reliably, and cost is low, easy maintenance, be fit to very much be used as the auxiliary calibration of hot rolling water cooling zone strip position, be particularly useful for Wide and Thick Slab and produce line, be applicable to the position probing field for detection of the hot rolled steel plate sheet material that passes through this place/band of water cooling zone on the iron and steel hot rolling line.
