Cov qauv no yog tsim raws li cov khoom ntawm lub koom haum ntawm lub tuam txhab, nyob rau hauv cov kev pab cuam kev tswj hom, kom standardize kev tswj ntawm pwm nyob rau hauv aluminium factories, txhim kho kev siv efficiency ntawm pwm, thiab xyuas kom meej ntau lawm.
Aluminium pwm scrapped rau ntau yam: ua ntej, txhuas extrusion pwm ua hauj lwm tej yam kev mob yog heev phem, muaj peev xwm ntawm withstanding lub khaus nyob rau hauv siab kub thiab siab sib txhuam, hnav, raws li cov txheeb cais qhia tau hais tias cov pwm ntau lawm muaj peb lub ntsiab tsis ua hauj lwm cov ntaub ntawv: (1) kev sib txhuam thiab hnav tsis ua hauj lwm (65%), (2) qaug zog tawg tsis ua hauj lwm (18%), (3) cov yas deformation thiab cov khoom tsis ua hauj lwm suav txog 15%. Cov khoom siv extruded tsis tuaj yeem ua tau raws li cov kev cai ntawm cov qauv khoom thiab tsis tuaj yeem kho. Qhov kev pab cuam lub neej ntawm qhov tuag feem ntau piav qhia los ntawm qhov ua tau zoo flux.
1. Cov txheej txheem Scrap Yog tias pom tias cov pwm raug puas los yog hnav tom qab siv thiab kho tsis tau, lub tuam txhab khaws cia pwm ntawm Chaw Tsim Khoom yuav tsum sau cov pwm scrapping daim ntawv thov, uas yuav tsum tau tshuaj xyuas los ntawm tus thawj tswj hwm ntawm lub tuam txhab thiab pom zoo. los ntawm tus thawj tswj hwm ntawm lub tuam txhab.Lub tuam txhab kev lag luam yuav tsum thov rau kev ua cov tshuaj tshiab
Ii. Scrap Standard Cov txheej txheem ntawm cov pwm yuav tsum xa mus rau cov kev cai hauv lub tebchaws thiab cov txheej txheem tswj cov cuab yeej cuab tam tsim los ntawm lub tuam txhab, raws li hauv qab no:
Cov khoom siv thev naus laus zis thiab cov qauv zoo
(1) Cov khoom tau tso tseg tsis tau txais kev txiav txim thiab cov khoom tsim los ntawm cov pwm tsis muaj.
(2) Thaum cov pwm tau mus txog qhov kawg ntawm nws lub neej thiab raug puas tsuaj loj, nws tsis tuaj yeem khaws cia thiab siv tau.
(3) Vim yog qhov kev hloov pauv, cov khoom qub hloov pauv, cov pwm tsis tuaj yeem hloov lossis siv tau.
(4) Cov pwm yog tawg, thiab qhov chaw roughness yuav tsum tau los ntawm cov khoom tsis tuaj yeem ua tau raws li cov txheej txheem khoom;
(5) Cov pwm tsis kam lees yog siab, uas tsis siv tau tom qab ntau tshaj peb zaug ntawm" Lub Rooj Sib Tham Sib Tham" daws;
(6) Cov pwm feem ntau puas vim muaj ntau yam vuam, yog li nws tsis tuaj yeem ua kom tiav cov khoom ntawm ib qho kev hloov ib txwm;
(7) Qhov loj ntxig ntawm cov pwm tawg, thiab nws tsis yog kev lag luam los tsim cov ntxig;
(8) Vim yog vim li cas tsim thiab tsim, pwm feem ntau sticks rau pwm, qhov loj yog tsis kam rau siab, thiab efficiency yog tsawg.
(9) Lwm yam ua rau tsis siv cov pwm
