Lub luag haujlwm ntawm aluminium alloy additives

Aluminium alloy khoom yog dav siv nyob rau hauv ntau lub teb vim lawv cov kev ua tau zoo heev.Txawm li cas los xij, lawv cov kev ua tau zoo heev tsis tuaj yeem raug cais tawm ntawm ntau yam ntawm aluminium alloy additives.Nyob rau hauv xyoo tas los no, aluminium alloy additives tau dhau los ua cov khoom tseem ceeb rau kev txhim kho kev ua tau zoo ntawm aluminium alloys thiab refining cov qauv nplej.

Aluminium alloy additivesyog cov tshuaj uas tau ntxiv rau cov hlau molten thaum lub sijhawm tsim khoom.Cov additives no pab ntau yam haujlwm thiab muaj kev cuam tshuam loj rau cov khoom kawg.Lub luag haujlwm ntawm cov additives txawv txawv, piv txwv li,chromium additives, uas ua lub luag haujlwm tseem ceeb hauv kev sib ntxiv ntawm chromium rau aluminium alloys thiab kev ua kom zoo ntawm cov qauv nplej, thiabmanganese additives, uas tuaj yeem cuam tshuam cov ntsiab lus ntawm manganese hauv cov khoom siv aluminium alloy.

Ntawm zhelu, aluminium alloy additives tseem hu ua 75% aluminium alloy additives, uas txhais tau hais tias cov ntsiab lus ntawm cov tshuaj ntxiv rau cov additives yog 75% thiab tus so yog aluminium, uas plays lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm thiab zoo ntawm aluminium alloy khoom.Tsis tas li ntawd, aluminium alloy additives uas ua los ntawm zhelu muaj cov txiaj ntsig ntau dua 95%.Qhov no optimizes raw khoom siv, txo cov pov tseg thiab maximizes efficiency.Qhov no tsis yog tsuas yog pab cov tuam txhab lag luam kom txo cov nqi, tab sis kuj txhawb kev txhim kho kom ruaj khov ntawm tag nrho kev lag luam.

Kev tiv thaiv ib puag ncig thiab tsis muaj kuab paug tau dhau los ua kev txhawj xeeb loj ntawm lub zej zog.Muaj kev paub ntau ntxiv txog qhov tseem ceeb ntawm kev tiv thaiv ib puag ncig thiab kev xav tau kev ntsuas tus phooj ywg ib puag ncig hauv txhua qhov kev lag luam.Ib qho zoo ntawm kev siv aluminium alloy additives yog kev tiv thaiv ib puag ncig.Cov tshuaj phem yog inevitably tsim nyob rau hauv chemical ntau lawm.zhelu's additives tsom rau kev tiv thaiv ib puag ncig thiab kev tsim khoom tsis muaj kuab lom.Lawv ua raws li cov kev cai nruj thiab pab txo cov emission ntawm cov pa phem thaum lub sij hawm tsim khoom.

Qee qhov aluminium alloy additives kuj muaj qhov cuam tshuam tseem ceeb ntawm cov hlau.Los ntawm kev qhia cov ntsiab lus tshwj xeeb rau hauv cov hlau molten, cov additives no pab tshem tawm impurities, txhim kho homogeneity ntawm cov hlau thiab txhim kho nws cov khoom siv kho tshuab.Piv txwv li,magnesium ingot, ntxiv magnesium ingot lub hom phiaj tseem ceeb yog txhawm rau txhim kho aluminium alloy tuag casting kev ua tau zoo, tshwj xeeb tshaj yog corrosion kuj.Raws li cov kws tshaj lij, txhuas thiab magnesium alloy tuag casting yog lub teeb thiab tawv, zoo corrosion kuj, yooj yim rau vuam thiab lwm yam kev kho deg, yog tsim ntawm aircraft, foob pob ua ntxaij, speedboats, tsheb thiab lwm yam ntaub ntawv tseem ceeb.Tsis tas li ntawd, lub luag haujlwm ntawm aluminium alloy additives tsis yog tsuas yog txhim kho cov khoom siv dag zog, cov khoom siv ntxiv no kuj txhim kho lub machinability ntawm alloy, ua rau nws yooj yim rau kev ua thiab ua haujlwm.Lawv pab txo qhov tsis xws luag uas tshwm sim thaum lub sij hawm casting thiab molding, yog li ua kom cov qoob loo thiab txo cov nqi seem.Kev txhim kho machinability ntawm cov additives no pab txuag cov nqi thiab ua kom cov khoom tsim tau zoo.

Txawm hais tias additives ua lub luag haujlwm tseem ceeb hauv kev ua tau zoo ntawm cov khoom siv aluminium alloy, cov tuam ntxhab kuj yuav tsum tsim cov kev pab cuam sib txawv raws li cov yam ntxwv ntawm cov khoom sib txawv thiab lawv cov kev ua haujlwm kub.Piv txwv li, chromium, manganese thiabtooj liab nyob rau hauv aluminium alloy additives yuav tsum tau tag nrho ntxiv tsuas yog thaum lawv ua hauj lwm kub siab tshaj 730 ° C, whereassiliconthiabhlauyuav tsum tau siv nyob rau hauv ib puag ncig ntawm 740 ° C thiab 750 ° C, feem.Tsis tas li ntawd, rau ntau npaum, zhelu feem ntau yog coj los ntawm cov qauv no:

kev siv cov additives raug txiav txim siab rau qhov kawg ntawm cov khoom siv aluminium alloy.

Hauv kev xaus, aluminium alloy additives ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom zoo ib puag ncig kev ua haujlwm siab.Cov additives no pab txhawb kev ruaj ntseg ntawm kev lag luam los ntawm kev tsom mus rau ib puag ncig tus phooj ywg thiab tsis muaj kuab paug.Lawv lub peev xwm los ua kom zoo dua cov qauv, ua kom cov ntsiab lus ntawm cov khoom nyob rau hauv ib qho txhuas alloy thiab txhim kho lub machinability ntawm cov hlau ua rau lawv indispensable nyob rau hauv ntau yam teb.Raws li qhov kev thov rau ib puag ncig tus phooj ywg thiab cov ntaub ntawv zoo txuas ntxiv mus, yog li yuav qhov tseem ceeb ntawm aluminium alloy additives, paving txoj kev rau ib tug ntsuab, ntau npaum li cas yav tom ntej.
