Kev npaj ntawm titanium alloy extrusion raj yog txheej txheem nyuaj uas muaj ntau yam txheej txheem, nrog rau cov txheej txheem tseem ceeb suav nrog: kev npaj ingot → billet ua → cua sov → extrusion → tshav kub kho → tiav → tshuaj xyuas.
Ua ntej, kev npaj raw khoom yog qhov tseem ceeb. Titanium thiab titanium alloy ingots yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm GB / T 3620.1 tus qauv, nrog kev tswj nruj ntawm cov ntsiab lus ntawm cov khoom tsis zoo. Cov ingots yuav tsum tsis muaj qhov tsis xws luag xws li porosity, cais, lossis suav nrog, thiab cov nplej loj yuav tsum tsis sib xws. Cov ingots yog forged los qhib lub billet, npaj pas nrig billets uas ua tau raws li cov kev cai extrusion.
Kev npaj Billet ua ntej extrusion yog qhov tseem ceeb heev. Tom qab drilling, pas nrig billets feem ntau xav tau txheej txheem cladding, ua raws li kub extrusion los tsim extrusion raj billets. Cov cua kub ntawm lub ingot yuav tsum raug txiav txim siab raws li hom alloy, thiab lub sij hawm tuav yuav tsum txaus thiab sib xws los tiv thaiv overheating. Extrusion tsis xws li kub, ceev, thiab siab piv yuav tsum tau teem raws li lub alloy tus yam ntxwv. Cov alloys sib txawv yuav tsum muaj qhov sib txawv extrusion, thiab cov tuag yuav tsum ua kom tau raws li qhov yuav tsum tau ua thiab ua kom tsis tu ncua.
Tom qab extrusion, cov hlab ntsha yuav tsum tau txias kom sai, tswj cov cua txias kom tsis txhob muaj qhov txawv txav ntawm microstructure thiab cov khoom. Qhov no yog ua raws li kev kho cua sov, suav nrog cov khoom siv hluav taws xob zaum kawg, kom ua tiav cov khoom siv hluav taws xob tau teev tseg hauv kev tsim. Kev kho saum npoo muaj cov txheej txheem xws li pickling kom tshem tawm cov nplai oxide, ua kom lub ntsej muag roughness ua tau raws li qhov xav tau yam tsis muaj khawb, xeb, lossis lwm yam tsis xws luag.
Thaum kawg, nws tau hais meej tias cov raj yuav tsum tau ua kom ncaj thiab tsis yog - kev kuaj kev puas tsuaj xws li kev tshuaj xyuas ultrasonic kom ntseeg tau tias cov khoom zoo raws li cov kev xav tau ntawm kev siv. Cov txheej txheem ua tiav no ua kom ntseeg tau tias qhov zoo ntawm titanium alloy extrusion raj yog tswj tau los ntawm cov khoom siv raw mus rau cov khoom tiav.
