Cov txheej txheem centrifugal casting thiab kev xav tau ntawm tin
bronze bushingFeem ntau suav nrog cov hauv qab no:
Casting txheej txheem:
Lub centrifugal casting txheej txheem ntawm tin bronze bushing yog ib txoj kev ntawm casting tshwj xeeb castings xws li rings, raj, thooj voos kheej kheej, bushing, thiab lwm yam los ntawm kev siv centrifugal quab yuam. Thaum lub sij hawm casting txheej txheem, cov kua alloy yog sau thiab solidified nyob rau hauv qhov kev txiav txim ntawm centrifugal quab yuam kom tau ib tug casting. Cov yam ntxwv ntawm txoj kev casting no yog cov hlau zoo shrinkage them nyiaj, ntom txheej txheej txheej ntawm cov casting, ob peb non-metallic inclusions, thiab zoo mechanical zog.
Technical xav tau:
1. Kev sib txuas ntawm melting: Tus nqi yuav tsum tau degreased thiab xeb, khaws huv si, thiab cov khoom siv npog xws li charcoal yuav tsum muab ntxiv rau hauv qab ntawm lub cub hluav taws xob. Qhov kub ntawm cov kua tooj liab yuav tsum tau tswj nruj me ntsis thaum smelting. Feem ntau nws yog qhov tsim nyog los ua ntej deoxidize cov hlau ntawm qhov kub ntawm 1150 ~ 1200 ℃, thiab kub nws mus txog 1250 ℃ rau qhov kawg deoxidation thiab refining.
2. Kev tswj cov khoom siv: Thaum casting ntshiab tooj liab thiab tin bronze, yuav tsum tau them nyiaj mloog mus rau qhov txwv tsis pub cov ntsiab lus impurity, thiab tsis txhob siv cov cuab yeej hlau, crucibles uas tau melted lwm yam tooj liab alloys, thiab paug cov ntaub ntawv siv dua. Tin bronze bushing muaj zog gas nqus. Txhawm rau txo cov pa nqus pa, lawv yuav tsum tau yaj sai sai hauv qhov chaw tsis muaj zog oxidizing lossis oxidizing cua thiab nyob rau hauv kev tiv thaiv ntawm tus neeg sawv cev npog.
Thov nco ntsoov tias cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb. Cov txheej txheem casting tshwj xeeb thiab cov kev xav tau yuav raug kho raws li qhov tshwj xeeb daim ntawv thov scenario, cov khoom siv thiab cov neeg siv khoom xav tau. Hauv kev ua haujlwm tiag tiag, cov txheej txheem tsim nyog thiab cov txheej txheem kev nyab xeeb yuav tsum ua raws li nruj me ntsis kom ntseeg tau tias kev ua tiav ntawm cov txheej txheem tsim khoom thiab cov khoom ruaj khov.
