Abstract
The utility model discloses a measuring system for length of a steel billet on a roller bed. The measuring system is designed for solving the problem that the length of the steel billet measured by the present measuring system is not accurate enough. The measuring system for the length of the steel billet on the roller bed provided by the utility model comprises two cold/heat metal detectors, a controller and an encoder, wherein the two cold/heat metal detectors are arranged at an interval along a motion direction of the steel billet on the roller bed; detected signals of the cold/heat metal detectors are connected with the controller; the encoder is in communicating connection with the controller; and a distance between the two cold/heat metal detectors is the average length of to-be-detected steel billets moving on the roller bed. The measuring system has a simple structure and is high in accuracy of the measured length of the steel billet.
Description
Technical field
The utility model relates to the length detection system of steel billet on a kind of roller-way.
Background technology
In the existing steel rolling mill, steel billet is sent in the heating furnace by roller-way and heats.In the time of normal production, steel billet is entering the stokehold and all need to detect at the pan feeding roller-way length of steel billet, to judge whether steel billet is fit to send in the heating furnace, if steel billet is of convenient length, the steel billet length that detects need to be delivered among the PLC of reheat furnace system, to satisfy the positioning requirements of steel billet in stove.Only has the steel billet length signals of detection accurately and reliably, the so accurate location of guarantee steel billet in stove, guarantee can not forbidden not swipe because of the location of steel billet in the furnace wall of heating furnace, affect the life-span of stove, also avoid in addition the inclination of steel billet in stove, also guaranteed the tapping rhythm of heating furnace.The detection mode that usually adopts now is to adopt the mode of a cold/hot metal detector matching coding device, namely after the cold/hot metal detector detects the rising edge pulse that steel billet stops, just begin to read encoder encodes, when the cold/hot metal detector detects the steel billet afterbody and leaves, read the yardage when finishing, just can calculate the length of steel billet by the numerical value change of front and back encoder.But actual this detection method is subjected to the flexibility of steel billet, the length of steel billet and roller-way are with the frictional force of steel billet and the impact of skidding, larger error can appear in the detected steel billet length of such detection method, may cause steel billet in stove, to locate inaccurate, serious meeting scraping furnace wall, the situation appearance that steel billet tilts.
The utility model content
For the problems referred to above, the utility model provides a kind of steel billet length measuring system on the roller-way of steel billet linear measure longimetry precision that improved on the roller-way.
For achieving the above object, steel billet length measuring system on the utility model roller-way, comprise the encoder that controller that two cold/hot metal detectors that arrange along steel billet direction of motion interval on the described roller-way, described cold/hot metal detector connect and described controller connect, wherein the spacing between two cold/hot metal detectors is the average length of the steel billet to be detected that moves on the described roller-way.
Further, described two cold/hot metal detectors are scales, and described encoder is to become chi.
In the specific embodiment, described encoder is the absolute value encoder with the DP communication.
Steel billet length measuring system on the utility model roller-way, by with two cold/hot metal detectors as scale, utilize encoder as becoming chi, by the scale data and become the footage certificate in conjunction with detecting steel billet length, improved the precision of steel billet length testing value.
Description of drawings
Fig. 1 is the structural representation of the enforcement of steel billet length detection system on the utility model roller-way.
The specific embodiment
Below in conjunction with Figure of description the utility model is further described.
The below is specifically described the utility model to detect three kinds of situations that occur, and in following examples, the length of steel billet is L, distance between cold/hot metal detector D1 and the cold/hot metal detector D2 is the length of scale, be Lsp, the value that encoder measures is Lx for becoming the length of chi.
Situation one:
As shown in Figure 1, steel billet length measuring system on the present embodiment roller-way, the length that is used for steel billet on the test roller-way, described roller-way 5 both sides are provided with roller-way baffle plate 6, roller-way connects the electric machines for roller 7 that the roller-way rotation is provided, steel billet length measuring system on the roller-way described in the present embodiment, comprise and be arranged on the roller-way baffle plate outside, two cold/hot metal detector D2 that arrange along steel billet direction of motion interval on the described roller-way, D1, the encoder 3 that the controller 4 that described cold/hot metal detector communication connects and described controller communication connect, described cold/hot metal detector comprises transmitter 11,21 and receiver 12,22, described receiver connects described controller PLC, wherein the spacing between two cold/hot metal detectors is the average length of the steel billet to be detected that moves on the described roller-way, and cold/hot metal detector D2 is front, cold/hot metal detector D1 is rear, and namely steel billet passes through first D2 at process D1.Described two cold/hot metal detectors are scales, and namely the distance between two cold/hot metal devices is constant as cut lengths, and described encoder is to become chi, read difference between the average length of steel billet to be measured and steel billet by reading for becoming chi length.Described encoder is the absolute value encoder with the DP communication.
During use, to fire door motion, steel billet passes through first cold/hot metal detector D2 to steel billet on roller-way, again by cold/hot metal detector D1, when the D1 test point send the pulse of signal rising edge the time, the D2 test point has signal, begins to read the yardage of encoder this moment.At the D1 test point signal is arranged, when the D2 test point sends the signal trailing edge, stop counting, by the poor change chi length L x that just can detect of encoder yardage before and after relatively, Lx gets on the occasion of, the length L=Lsp+Lx of steel billet in this case.
Situation two:
During use, steel billet moves to fire door on roller-way, steel billet passes through first cold/hot metal detector D2, again by cold/hot metal detector D1, when D2 detects the signal trailing edge, simultaneously the D1 test point do not detect the steel billet signal time, begin counting, read the yardage of encoder, send the rising edge signal at the D1 test point, read the encoder yardage, stop counting, become chi length L x by poor just can the detecting of encoder yardage relatively, Lx gets negative value in this case, the length L=Lsp+Lx of steel billet.
Embodiment 3:
During use, steel billet moves to fire door on roller-way, steel billet passes through first cold/hot metal detector D2, again by cold/hot metal detector D1, when the D1 test point has sent the rising edge signal, the D2 test point has sent the signal of trailing edge simultaneously, and encoder need not start, Lx=0, the length L=Lsp+Lx of steel billet.
More than; it only is preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
