Description
Technical field:
The invention belongs to rolling detection technique field, especially relate to a kind of sheet material electronic detection and control system.
Background technology:
In rolled plate is produced, the thickness of sheet material, convexity and plate shape are the leading indicators weighing product quality.For strips or plates, its convexity and thickness error require in certain tolerance band, and its plate shape wants good, do not allow obvious waveform, deformed steel strip pair and mill operation have a significant impact, the serious bad meeting of plate shape causes strangling roller, rolls card, broken belt, the accident such as to tear occur, mill operation cannot normally be carried out.
During plate rolling, rolling technique personnel generally for and to improve the technique of production scene or improve, comprehensive detection must be carried out to the parameter such as convexity and plate shape of the transverse and longitudinal thickness of sheet material under current rolling mill practice and distribution, sheet material, to formulate corresponding corrective measure, improve the quality of plate product.
For a long time, the relevant parameter of rolled plate product is all to be worked sampling measurement by people, traditional detection method uses survey tool (as slide measure, micrometer caliper) clamping in the thickness direction of measured object, obtains thickness and other parameters of thing to be measured with this.But this measurement only reflects the thickness indication of sheet material, and be difficult to carry out on-line measurement in the operation of rolling, there is very large drawback and limitation.Along with the development of rolling detection technique, domestic in succession there is sheet material contact-type detection and contactless detection device, solve the problem of the on-line checkingi of sheet material, but, existing checkout gear often can only detect one of them of the large leading indicator (thickness of sheet material, convexity, plate shape) of rolled plate three, application can be rarely had to the device that the leading indicator of sheet material makes comprehensive detection, therefore, in rolled plate actual production, technical staff be badly in need of a kind of can to the thickness of sheet material, convexity and plate shape carry out the device of online comprehensive detection.
At present, the checkout gear of internal sheet metal mainly adopts two class metering systems: one is contact type measurement, and the contact by touch sensor directly contacts with the upper and lower surface of measuring object, and applies certain contact stress and measure.Another kind is non-contact measurement, mainly comprises ray method, supercritical ultrasonics technology, electric vortex method, capacitance method, laser method etc.But different measuring methods and device have different technical disadvantages and range of application.Contact measurement is by the case hardness of contact level, measuring object, and the factor impacts such as surface roughness, certainty of measurement is difficult to reach accurate.Often manufacturing cost is higher for the instrument that non-contact measurement relates to or device, and maintenance cost has high input, and maintenanceability is poor.In non-cpntact measurement, laser measurement method is subject to the impact of the factors such as environment, surface texture, measured object inclination, fluctuation, its degree of accuracy of measuring can not get satisfactorily resolving always, existing laser measuring equipment is easy to fluctuate by rolling mill vibration, pole piece grain structure, pole piece, laser measuring head, on the impact of the restriction of dynamic object capturing ability, causes the degree of accuracy of measurement undesirable; Ray method certainty of measurement is high, can realize fast speed non-contact and measure, but the health hazard of personnel that operate for long campaigns of ray is very big and cause radioactive pollution in environment; Electric vortex method and capacitance method are only applicable to the production line of cold rolling, and require high to measurement environment, and certainty of measurement affects larger by extraneous factor.
Based on the demand of in the comparison of the merits and demerits to current domestic existing checkout gear two class measuring method and Rolling Production, the quality index of plate product being carried out to comprehensive detection, investigate on the production process of rolled plate and the basis of existing sheet material on-line measuring device on the spot, patent of the present invention proposes a kind of sheet material electronic detection and control system, achieve the complete detection of the three norms of sheet material, overcome the technical deficiency of existing measurement mechanism to greatest extent, reduce checkout gear at the cost manufactured and in maintenance and repair, make this checkout gear in the application of actual production more extensive and economy.
summary of the invention:
Instant invention overcomes the weak point in prior art, provide a kind of sheet material electronic detection and control system.
A kind of sheet material electronic detection and control system, is made up of movable roll, stationary roll, detection probe, measuring roll, upper backup roll, lower backing roll, programmable logic controller (PLC), digital-to-analogue (D/A) converter, sensor controller, rolled plate, computer.
Described stationary roll is fixedly mounted in the frame of checkout gear, and in the rack-mounted sliding tray of movable roll, movable roll can move up and down.
Described lower backing roll is fixedly mounted in the frame of checkout gear, and in the rack-mounted sliding tray of upper backup roll, lower upper backup roll can move up and down.
Described measuring roll is fixedly mounted in frame, and detection probe is arranged on by fixed block and regulates on crossbeam, and detection probe installs linear displacement transducer.
Described data processing module comprises programmable logic controller (PLC), digital-to-analogue (D/A) converter, sensor controller, computer.Data processing module can carry out computing, compare, process the data detected, and Output rusults.
Beneficial effect of the present invention: the present invention overcomes the technical deficiency of existing sheet material checkout gear, achieves the detection of rolled plate three norms.This kind of sheet material electronic detection and control system, frame for movement is simple, and Measurement sensibility is high, affect little by extraneous factor, be easy to maintenance, can carry out on-line measurement to the thickness of rolled plate, convexity and plate shape in real time, the application therefore in actual production is more extensive.
