1. Taw qhia txog tooj liab qws
Copper rods xa mus rau cov khoom siv tooj liab ua los ntawm extrusion lossis kos duab. Muaj ntau hom tooj liab pas nrig, xws li liab tooj liab pas nrig, tooj dag, tooj liab rods thiab dawb tooj liab rods. Ntau hom tooj liab rods muaj cov txheej txheem sib txawv thiab cov yam ntxwv sib txawv. Copper pas nrig ua cov txheej txheem suav nrog extrusion, dov, nruam casting, ncab, thiab lwm yam.
2. Kev faib tawm ntawm cov khoom siv tooj liab
Cov ntaub ntawv ntawm cov pas nrig tooj liab muaj xws li H59, H59-1, H59-2, H59-3, H60, H60-2, H62, H63, H65, H68, H70, H80, H90; C1100, C1020, C2680, C2800, C2600, C2801, C5191, C5210, C2200, C7521, C7541, C17200, C1070, C7701, QSn6.{{28}n.{3, QSn. 32}}.3, BZn18-18, BZn15-20, CuBe2, thiab lwm yam.
3. Copper pas nrig txoj kev
Muaj peb hom tooj liab qws txheej txheem, raws li hauv qab no:
1. Extrusion-(rolling)-stretching-(annealing)-cov khoom tiav.
2. Nruam casting (saum toj, kab rov tav los yog log, crawler, impregnation)-(rolling)-stretching-(annealing)-cov khoom tiav.
3. Nruam extrusion-stretching-(annealing)-cov khoom tiav-cov khoom tiav.
4. Copper pas nrig txoj kev
Extrusion
1. Hom extrusion
(1) Forward extrusion: hais txog tus cwj pwm extrusion nyob rau hauv uas extrusion kev taw qhia ntawm cov khoom yog tib yam li extrusion quab yuam kev taw qhia.
(2) Rov qab extrusion: yog hais txog extrusion tus cwj pwm nyob rau hauv uas extrusion kev taw qhia yog opposite rau extrusion quab yuam kev taw qhia.
(3) Tshwj xeeb extrusion: yog hais txog lwm txoj kev extrusion xws li hydrostatic extrusion.
2. Cov yam ntxwv ntawm extrusion
(1) Cov yam ntxwv ntawm kev xa tawm mus rau pem hauv ntej: Cov khoom siv rau pem hauv ntej extrusion yog qhov yooj yim thiab yog siv dav tshaj plaws.
(2) Cov yam ntxwv ntawm thim rov qab extrusion: Rov qab extrusion txo qhov kev sib txhuam ntawm cov billet thiab cov extrusion chim, txo cov extrusion quab yuam, thiab tuaj yeem ua rau lub neej ntawm cov cuab yeej. Nws yog dav siv nyob rau hauv me me thiab nruab nrab-qhov loj me extruded khoom.
(3) Cov yam ntxwv tshwj xeeb extrusion: Tshwj xeeb extrusion feem ntau yog siv rau extrusion ntawm cov khoom tshwj xeeb.
