Compared with the prior art, the invention has the beneficial effects that: the method can rapidly and quantitatively measure the warpage amount of the intermediate blank on line, provides a data basis for timely adjusting process parameters, effectively avoids accidents caused by the warpage of the intermediate blank, improves the product quality and the production efficiency, and brings economic benefits for enterprises.
Description
Technical field
The present invention relates to metallurgical engineering technical field, relate in particular to a kind of on-line measurement device and measuring method of hot rolled strip intermediate blank amount of warpage.
Background technology
At present, hot rolled plate band in process of production, the phenomenon that intermediate blank after roughing mill rolling exists head to upwarp or has a downwarp due to reasons such as upper and lower surface temperature difference, top and bottom rolls speed differences, to equipment such as the width gage at the quality of steel plate and steel mill machine exit place and stay-warm cases, can play destruction in various degree like this, cause adverse effect to production direct motion and quality control.Therefore, thus this amount of warpage of intermediate blank is measured to be controlled seems particularly important.
Summary of the invention
The object of the present invention is to provide a kind of on-line measurement device and measuring method of hot rolled strip intermediate blank amount of warpage, utilization is arranged on optical signal transmitter and the optical signal receiver of roller-way both sides intermediate blank is monitored, when intermediate blank has been blocked optical signal during by measured zone, optical signal receiver is presented at signal in terminal by the PLC computer connecting, the amount of warpage of on-line measurement intermediate blank that can be rapid, quantitative.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of on-line measurement device of hot rolled strip intermediate blank amount of warpage, comprise optical signal transmitter, optical signal receiver, PLC computer, display terminal, it is characterized in that, described optical signal transmitter is comprised of several light launchers, optical signal receiver is comprised of several light receiving systems, optical signal transmitter and optical signal receiver are set in parallel in roller-way both sides, and optical signal receiver is connected with PLC computer, and PLC computer is connected with display terminal.
Described light launcher is identical with light receiving system quantity.
Described light launcher is arranged in optical signal transmitter with same interval vertical.
Described light receiving system is arranged in optical signal receiver with same interval vertical.
Described light launcher is corresponding one by one with light receiving system.
The method that realizes the on-line measurement of hot rolled strip intermediate blank amount of warpage, concrete steps are as follows:
1) optical signal transmitter and optical signal receiver are arranged on respectively the roller-way both sides that intermediate blank is passed through;
2) will with the light receiving system in high optical signal receiver, in PLC computer, be set to logical zero position with roller-way upper surface;
3) shading light signal when the intermediate blank of warpage is by measurement zone, according to the number of the light receiving system being blocked in optical signal receiver, in conjunction with spacing, can calculate amount of warpage, be presented on display terminal after analog signal being converted to data signal by PLC computer.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention can be rapidly, the amount of warpage of on-line measurement intermediate blank quantitatively, for carrying out in time technological parameter adjustment, provide data foundation, effectively avoided, because intermediate blank warpage has an accident, having improved product quality and production efficiency, for enterprise brings economic benefit.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further illustrated:
As shown in Figure 1, a kind of on-line measurement device of hot rolled strip intermediate blank amount of warpage, by optical signal transmitter 1, optical signal receiver 2, PLC computer 3 and display terminal 4, formed, described optical signal transmitter 1 is comprised of several light launchers, optical signal receiver 2 is comprised of several light receiving systems, optical signal transmitter 1 is set in parallel in roller-way both sides with optical signal receiver 2, and optical signal receiver 2 is connected with PLC computer 3, and PLC computer 3 is connected with display terminal 4.Light launcher is identical with light receiving system quantity, light launcher is with same spacing a(mm) be vertically set in optical signal transmitter, light receiving system is with same spacing a(mm) be vertically set in optical signal receiver, light launcher is corresponding one by one with light receiving system.
The method that realizes the on-line measurement of hot rolled strip intermediate blank amount of warpage, concrete steps are as follows:
1) optical signal transmitter 1 and optical signal receiver 2 are arranged on respectively the roller-way both sides that intermediate blank is passed through;
2) will with the light receiving system in high optical signal receiver 2, in PLC computer, be set to logical zero position with roller-way upper surface;
3) shading light signal when the intermediate blank of warpage is by measurement zone, according to the number of the light receiving system being blocked in optical signal receiver 2, in conjunction with spacing, can calculate amount of warpage, be presented on display terminal after analog signal being converted to data signal by PLC computer.
Optical signal transmitter and optical signal receiver are arranged on respectively the roller-way both sides that intermediate blank is passed through, to with the light receiving system in high optical signal receiver, in PLC computer, be set to logical zero position with roller-way upper surface, when the intermediate blank of warpage has been blocked optical signal during by measurement zone, according to the number of the light receiving system being blocked in optical signal receiver, in conjunction with spacing a(mm) can calculate amount of warpage, be presented on display terminal after analog signal being converted to data signal by PLC computer.
During work, more than logical zero position n to the m(m > n in optical signal receiver 1) individual light signal receiving 2 is blocked, show that intermediate blank lower surface is n*a(mm apart from roller-way upper surface distance), can draw thus, intermediate blank upper surface is m*a(mm apart from roller-way upper surface distance), the amount of upwarping is n*a(mm); When intermediate blank has a downwarp, measuring principle is similar.
