Wire feeder

Abstract

The invention provides a wire feeder. The speed of a grain refiner is detected and controlled by a monitoring device in real time, whether the difference X between the actual conveying speed acquired by the monitoring device and a theoretical conveying speed is within an allowable error range A is judged by a speed control device, so that the speed provided by a power device is adjusted, finally, the fault rate in the wire feeding process can be reduced, and the ingot quality is improved.

Description

technical field [0001] The invention belongs to the technical field of alloy treatment, in particular to a wire feeder. Background technique [0002] In the melting and casting production line, the wire feeder is the key equipment that affects the internal structure (especially the grain size) of the final product quality in aluminum alloy casting. It is the online addition of titanium, boron and rare earth and other easily oxidizable trace elements Sufficient grain refiner, one of the most effective measures to achieve grain refinement of ingot structure. In the process of alloy casting, it is necessary to use the wire feeder to accurately transport the grain refiner such as aluminum titanium boron wire to the bottom of the metal liquid flow tank at a reasonable speed to ensure that the grain refiner can be deposited on the metal Evenly dispersed at the bottom of the liquid. The addition of grain refiner can improve the quality of the alloy and improve the castability of ...

AI Technical Summary

Problems solved by technology

However, due to problems such as poor process reproducibility caused by the aging of the wire feeder drive, frequent failures such as non-feeding and jamming are prone to occur during the wire feeding process, human monitoring is not timely, and at the same time, it is prone to insufficient power, which makes the final product The content fluctuation of trace elements such as titanium or boron and the deviation of alloy composition are large, resulting in unstable grain refinement effect of cast structure, thus affecting the quality of final ingot
