Study on the Processing Technology of ERTI-7 Titanium Wire Based on AHP-PQ Model
This article determines the main factors influencing the quality of ERTi-7 titanium wire through building AHP-PQ model: processing technology. under the circumstance of instable quality of ERTi-7 titanium wire in international market. Through the selection of raw material, feeding material evenly during melting, control of melting times and the determination of surface machining process, the inhomogeneity of chemical compositions of ERTi-7 and the corresponding removal method are studied. The results show that it is easier to obtain ingot with good surface and fine structure using triple melting without increasing the content of Pd element, and then going through non-oxidation roller-die drawing process, we will obtain qualified titanium wire with good surface and also conforming to the request of AWS A5.16/A5.16M:2007.
