The difference X of conveying speed and theoretical conveying speed whether in allowable error range A, if not in allowable error range A, speed
The speed that degree control device provides power device is adjusted, until difference X is in allowable error range A.It is theoretical defeated herein
Sending speed is to need to convey the theoretical conveying speed of grain refiner on 1 electric machine theory of wire feeder head.
Specifically, the actual speed of grain refiner such as aluminium titanium boron (carbon) silk is obtained by monitoring device, according to alloy institute
The radical of the grain refiner of the weight and addition of the grain refiner needed objectively obtains on 1 electric machine theory of wire feeder head
Need to convey the theoretical conveying speed of grain refiner, if the difference X of actual fed speed and theoretical conveying speed is not permitting
Perhaps in error range A, then just needing to adjust the speed of 1 motor of head conveying grain refiner, since the conveying crystal grain of head 1 is thin
The speed of agent is by 1 internally-powered device such as Frequency Converter Control of wire feeder head, so needing to adjust the control of power device
Speed, adjusting once cannot may still make actual fed speed be equal to theoretical conveying speed or close theoretical conveying speed setting speed
Degree, so needing to adjust repeatedly until the actual fed speed difference equal or both with theory conveying speed is in allowable error model
In enclosing.
Compared with the existing technology, this programme is passed through using the speed of monitoring device real-time detection and control grain refiner
Whether speed control unit judges the difference X of the actual fed speed that monitoring device obtains and theoretical conveying speed in allowable error
In range A, so that the speed provided power device is adjusted, it finally can reduce failure rate during feeding silk, mention
High ingot quality.It is all objectively nobody due to obtaining actual fed speed, theoretical conveying speed and controlling the process of speed
For factor, so being easy to be accurately controlled the additive amount weight of grain refiner, the significantly more efficient matter for improving ingot casting crystal grain
Amount.
Optionally, wire feeder further includes human-computer interaction device, has input and display function, for grain refiner
Input the display of the setting of parameter and/or the operating parameter of grain refiner.The input parameter for needing to be arranged can be for as fed silk
