Extrusion: Qhov kev rho tawm ceev yuav tsum tau ua tib zoo tswj lub sijhawm txheej txheem txheej txheem. Kev nrawm nrawm muaj lub zog tseem ceeb ntawm deformation thaum tshav kub kub, Aluminium rau lub tsev deformation uniformity, recrystallization thiab cov txheej txheem daws teeb meem, Aluminium rau lub tsev tsim cov khoom siv kho tshuab thiab cov khoom lag luam zoo.
Txhawm rau txhawm rau txhim kho kev tsim khoom, raws li xyoo ntawm kev sib tham ntau lawm thiab nthuav kev paub, Aluminium rau lub tsev peb cov txheej txheem tseem ceeb extrusion tam sim no ua raws li" tsis tshua muaj qhov kub thiab tsis kub ceev" cov txheej txheem ntau lawm, Aluminium rau lub tsev uas yog, qhov kub ntawm lub pas nrig txhuas yog qhov sib xyaw ua ke rau qhov ceev nrawm, Aluminium rau lub tsev thiab qhov ntsuas kub ntawm txhuas tus pas nrig yog qhov siab thiab qhov rho tawm ntawm qhov nrawm nrawm ua kom qeeb qeeb, Aluminium rau lub tsev tsim qhov kub ntawm txhuas tus pas nrig yog tsawg, thiab qhov ntsuas qhov hnyav ntxiv yog qhov tsim nyog ntxiv. Los ntawm hom kev hloov kho no, Aluminium rau kev tsim cov txheej txheem extrusion tau muab kho kom haum rau lub xeev zoo tshaj.
Nyob rau hauv ib txwm muaj xwm txheej, Aluminium rau kev tsim lub pwm sab saud tuaj yeem ua kom txias thiab ceev dua thaum tus pas nrig thib 3 tsim tawm. Qhov kub ntawm cov pwm tiaj tiaj aluminium pas nrig yog txo mus rau 390-410 ° C, Txhuas rau lub tsev thiab qhov kub ntawm lub pwm pwm txhuas pas nrig yog txo rau 410-430 ° C. Yog qhov zoo tshaj plaws.
Online Quenching: Quenching yog txhawm rau kom Mg2Si cov khoom khov-zom rau hauv cov hlau puag thaum kub ceev tom qab tau txias txias rau chav kub tom qab tau tawm los ntawm pwm. Txhawm rau 0.6-0.9% ntawm Mg2Si, Txhuas rau kev tsim cov qhov kub thiab txias qhov tseem ceeb yog txo txij li 500 degrees txog 204 degrees, Txhuas rau kev tsim cov dej txias tsawg kawg yog tsis pub tsawg tshaj 180 degrees C / min, dej txias yuav siv tau, Aluminium rau kev tsim lub hardness ntawm 6061 alloy aluminium template yuav tsum yog ≥15HW, thiab nws cov ntu loj yog quenched Rau qhov txias, Aluminium rau lub tsev 549 ℃ / min pom zoo.
Txog kev rho tawm on-line quenching, Aluminium rau kev tsim lub ntsuas cua txias yuav tsum ua raws li lub hauv paus ntsiab lus ntawm kev ua kom ntseeg tau tias cov kua dej tau ua tiav tau ua pa roj tau. Rau cov khoom lag luam tuaj yeem ua kom ncaj, Aluminium rau kev tsim kev ua tsov ua rog los ntawm kev ua kom qaug yog qhov tsawg thiab ua kom raug.
