Cov txheej txheem tsim khoom ntawm cov khoom siv txhuas hauv Chongqing tau muab faib ua peb txheej txheem: yaj thiab casting, kneading thiab oxidation.
1. Kev yaj thiab casting: Raws li cov cim lag luam alloy uas xav tau tsim tawm, qhov ntxiv ntawm ntau yam khoom sib xyaw ua ke raug suav, thiab ntau yam khoom siv raw tau sib phim zoo. Tom qab ntawd, cov khoom siv raw uas tau npaj tseg raug yaj hauv lub cub tawg yaj raws li cov kev cai lij choj, thiab cov khoom tsis huv thiab cov pa roj hauv cov yaj raug tshem tawm zoo los ntawm kev degassing thiab deslagging. Nyob rau hauv qee qhov kev mob forging, cov txhuas molten raug txias thiab forged rau hauv cov hlau cam khwb cia puag ncig ntawm ntau yam kev qhia los ntawm lub kaw lus forging tob.
2. Kev Sib Xyaws: Kev sib xyaws yog ib txoj kev tsim cov qauv. Ua ntej, cov pwm yog tsim thiab tsim raws li ntu lag luam ntawm cov qauv, thiab cov pas nrig kub kub yog extruded los ntawm cov pwm los ntawm kev siv lub tshuab sib xyaws. Cov khoom siv feem ntau siv 6063 alloy kuj tseem sib xyaws nrog cov txheej txheem quenching cua txias thiab cov txheej txheem laus tom qab kom ua tiav kev kho cua sov. Cov hom sib txawv ntawm cov khoom siv kho cua sov muaj cov qauv kho cua sov sib txawv. Tom qab kev txhim kho, qhov nyuaj tuaj yeem kuaj tau los ntawm W-20 Wechsler hardness tester.
3. Oxidation: Qhov kev tiv thaiv corrosion ntawm qhov chaw ntawm cov khoom siv txhuas uas tau kneaded tsis muaj zog, yog li nws yuav tsum tau kho los ntawm anodic oxidation kom ua rau muaj kev tiv thaiv corrosion, hnav tsis kam thiab kev zoo nkauj ntawm qhov chaw ntawm txhuas.
Cov ntaub ntawv txhuas hauv Chongqing tuaj yeem sib tw nrog Shanghai hauv qhov zoo vim yog kev txhim kho ntawm cov thev naus laus zis ntau lawm.
