Tuag casting txheej

2021-01-18
1. Dab tsi yog qhov tuag casting txheej?
Teb: Thaum lub sijhawm ua cov txheej txheem tuag-txheej txheem, cov tshuaj tsuag lub cev cov khoom siv thiab cov txheej txheem nyias nyias ntawm cov kab noj hniav phab ntsa, lub ntsiab lus saum npoo, pwm thiab tuag-casting tshuab kev sib txhuam yam (xws li zawv zawg, ejector cov ntsiab lus, punches thiab txhaj tshuaj sib xyaw) Cov dej sib xyaw yog ib txwm paub. raws li kuv lub teb chaws tuag-cam khwb cia hlau txheej.
2. Dab tsi yog qhov ua haujlwm ntawm kev tuag casting txheej txheej?
Teb: (1) Tswj qhov kev ua tau zoo lubrication thaum kub siab;
(2) Txhawm rau kom tsis txhob muaj qhov cuam tshuam los ntawm kev ntsuas kub ntawm qhov ntsuas qhov siab ntawm cov kab noj hniav, tiv thaiv qhov tshwm sim ntawm cov pwm, thiab txhim kho cov kev ua haujlwm ntawm tus qauv;
(3) Txhim kho qhov zoo ntawm lub alloy los ntawm kev txo cov thermal conductivity ntawm tus qauv thiab tswj lub fluidity ntawm molten alloy
(4) Txo txoj kev sib txhuam ntawm qhov nrum thiab cov pwm tsim tshuab feem ntawm kev lag luam, thiaj li txo qhov kev hnav ntawm qhov tseem ceeb thiab kab noj hniav, txuas ntxiv kev pab lub neej ntawm pwm thiab txhim kho qhov zoo ntawm cov ua haujlwm casting.
3. Dab tsi peb xav tau rau txheej txheej txheej txheej tuag-tuag?
Teb: (1) Qhov chaw volatilization tsawg tsawg, thiab lub zog dilution zog volatilizes ceev ceev ntawm 100 ~ 150â „ƒ.
(2) zoo coatability;
(3) Tsis muaj qhov cuam tshuam txog cov qauv thiab cov pov;
(4) zoo lubricity;
(5) Kev ruaj khov;
(6) Tsis muaj ntxhiab tsw tshwj xeeb, tsis muaj kev phom sij yuav raug nag lossis ziab ntawm qhov kub;
(7) Kev npaj ua tau yooj yim;
(8) Muaj ntau cov khoom siv thiab tus nqi qis.
4. Dab tsi yog cov nquag siv txhuas aluminium alloy tuag-casting txheej txheej?
Teb: (1) Graphite + lub tshuab roj, siv rau kev tsim cov thev naus laus zis, nrog ntau qhov kev txhaj tshuaj thiab ntau txoj kev txhaj tshuaj;
(2) Cov roj + bitumen, qhov sib piv yog 85/15, bitumen yog rhaub kom 80â „ƒ thiab tom qab ntawd yaj, cov roj yog sib xyaw tusyees, uas tuaj yeem tiv thaiv kom tsis txhob tuaj pwm.
