Thaum cov neeg feem coob hnov 'lub ntiajteb txawj nqus cam khwb cia hlau,' lawv pom ib qho yooj yim ncuav rau hauv cov xuab zeb pwm. Qhov ntawd yog qhov pib ntawm qhov pib, tab sis hauv kev xyaum, tshwj xeeb tshaj yog rau qhov chaw uas xav tau kev ncaj ncees tiag tiag, nws yog qhov pib qhov nyuaj. Lo lus nws tus kheej tuaj yeem yuam kev - nws tsis yog hais txog hlau thiab lub ntiajteb txawj nqus; Nws yog hais txog kev tswj kom muaj zog, tsim pwm, thiab tswj cov yam ntxwv ntawm cov hlau nyob rau hauv ib txoj kev uas lwm cov txheej txheem zoo li high-pressure die-casting tsis tuaj yeem kov rau qee yam kev siv. Kuv tau pom ntau cov duab kos tuaj nrog cov khoom siv spec ntawm 'cam khwb cia hlau' thiab cov txheej txheem hu rau 'lub ntiajteb txawj nqus casting' yam tsis muaj kev nkag siab meej ntawm kev lag luam tawm. Qhov kev xav yog feem ntau tias nws yog ib qho pheej yig, cov txheej txheem kev txawj ntse. Nws tuaj yeem raug nqi zoo, yog, tab sis tau txais nws tsis raug yog kim, thiab tau txais nws txoj cai yuav tsum muaj kev paub tob tob uas tsis pom tseeb tam sim ntawd.
Lub hauv paus ntawm cov txheej txheem: Nws nyob hauv Pwm thiab Hlau
Qhov sib txawv tiag tiag hauv qhov zoo pib ntev ua ntej cov hlau hits lub ladle. Nws nyob hauv pwm. Rau plhaub molding, uas lub tuam txhab nyiam Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) muaj kev sib sib zog nqus hauv, pwm nws tus kheej yog kho resin-sand composite. Qhov saum npoo tiav yog superior rau cov xuab zeb ntsuab, thiab qhov tseeb qhov tseeb yog nruj dua. Tab sis rau lub ntiajteb txawj nqus casting, lub rooj vag system-cov channel uas coj cov hlau molten-yog txhua yam. Koj tsis yuam hlau nyob rau hauv siab; koj nyob nraum cia siab rau lub ntiajteb txawj nqus thiab atmospheric siab los sau cov kab noj hniav. Yog tias lub rooj vag tsis raug, koj tau txais mistruns lossis turbulent flow uas rub oxides rau hauv ib feem, tsim cov ntsiab lus tsis muaj zog. Kuv nco qab txog ib pawg ntawm hydraulic valve lub cev uas peb tau pheej yig shrinkage porosity nyob rau hauv ib tug tuab seem. Qhov kho tsis yog qhov kub siab dua; nws yog redesigning lub rooj vag los txhawb kev taw qhia solidification ntawm ib tug riser peb yuav tom qab txiav tawm. Nws coj peb iterations.
Ces muaj hlau nws tus kheej. 'Cast Iron' tsis yog ib qho khoom siv. Rau lub ntiajteb txawj nqus casting, grey hlau (flake graphite) thiab ductile hlau (spheroidal graphite) yog cov feem ntau, tab sis lawv tus cwj pwm yog worlds sib nrug. Grey hlau muaj damping zoo thiab machinability tab sis nkig. Cov hlau muaj zog tensile ntau dua thiab qee qhov elongation. Kev xaiv ntawm lawv tsis yog ib qho kev kuaj xyuas khoom siv tshuab xwb; nws yog hais txog yuav ua li cas lawv solidify. Ductile hlau yuav tsum tau ceev faj inoculation kev kho mob ua ntej lub ncuav los xyuas kom meej cov graphite cov ntaub ntawv rau hauv spheres. Yog tias qhov kev kho mob ploj mus (nws muaj qhov txwv 'qhov rais'), lossis yog tias muaj cov sulfur ntau dhau hauv cov hlau hauv paus, koj tau degenerate graphite, thiab qhov kev ua tau zoo plummets. Nws yog ib qho teeb meem ntawm kev tswj cov txheej txheem nyob rau hauv pem teb foundry, tsis yog ib yam dab tsi uas koj tuaj yeem teev rau ntawm daim duab thiab tsis nco qab.
Qhov no yog qhov uas qhov kev sib koom ua lag luam mus sij hawm ntev tseem ceeb. Ib tus neeg muag khoom uas tuav ob qho tib si casting thiab tom qab CNC machining, zoo li QSY ua, muaj kev txaus siab rau kev tau txais lub suab nrov nrov txij thaum pib.
