Embodiment
This embodiment is that example describes with the position-measurement device of the band proportioning control system of the output strip line of smelter.
As shown in Figure 1, gage frame 6 is the nonferromagnetic section bar, as the rectangle framework that aluminium alloy extrusions is made, avoids the generation and the reception of the magnetic line of force in the electromagnetic induction effect are produced shielding, influences measurement effect.Simultaneously, gage frame 6 has certain intensity, can be installed in the framework by load bearing component.Also be provided with wire casing and sensor mounting groove in this framework, power lead and signal wire are installed in wire casing, the high-frequency electromagnetic sensor is installed in the sensor mounting groove, high-frequency electromagnetic emission sensor 1 is installed in the upper side frame of gage frame 6 both sides, high-frequency electromagnetic receiving sensor 2 is installed in the lower frame of gage frame 6 both sides, and high-frequency electromagnetic emission sensor 1 is corresponding with the upper-lower position of high-frequency electromagnetic receiving sensor 2.High frequency field power supply 3 adopts RC Wien bridge circuit sine-wave oscillator, the field power supply of 40KHz is provided to high-frequency emission electromagnetic sensor 1, field power supply is two groups of transmissions, the mutual interference of avoiding as shown in Figure 1 of receiving sensor phase when power amplifier is given the transmitting coil of high-frequency electromagnetic emission sensor 1, the 40KHz signal is carried out the timesharing modulation, promptly allow excitation signal can only act on one group of coil at one time, like this, both can avoid the mutual superposition of two sensors signal, can reduce the emission power consumption greatly again.The high frequency field power supply reaches to its powered switch power supply and also can be installed near in the aluminum alloy frame of sensor.
The signal of high-frequency electromagnetic receiving sensor 2 outputs to magnetic induction band proportioning control system 4 by signal wire.Gage frame 6 is installed in the output strip line, and band steel 5 is walked from the centre of gage frame 6.
The utility model is applied to the band proportioning control system on this enterprise's output strip line, it measures sensitivity can reach 5mm, measuring distance reaches 500～600mm, effectively prevented to cause the damage of product itself and production equipment because of the normal sideslip of being with steel, approach the effect that reaches lossless and non-maintaining, guaranteed the control accuracy in band steel centre position on the high speed output strip line.This device can be applicable on the band production line of copper, aluminium and other non-ferrous metals equally.
It should be noted last that, above embodiment only is used to the technical solution of the utility model is described and is unrestricted, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
