Daim ntawv thov ntawm ceramic ua npuas ncauj lim hauv aluminium casting

Daim ntawv thov ntawm ceramic ua npuas ncauj lim hauv txhuas casting yog ib qho tseem ceeb hauv kev ua kom zoo thiab purity nyob rau hauv cov txheej txheem ntau lawm.Ua los ntawmcov ntaub ntawv refractory, cov lim no muaj ibporous qauvuas zoo lim molten aluminium, uas ua rau huv si, zoo dua castings.

Ib qho ntawm cov laj thawj tseem ceeb yog vim li casceramic ua npuas ncauj limyog nyiam nyob rau hauv aluminium casting yog lawv muaj peev xwm mus zoo tshem tawm inclusions los ntawm molten aluminium.Kev siv lub tshuabtxoj cai ntawm adsorptionraws li ib tug pom mechanism, zoo tshem tawm impurities thiab pliaj ntsiab uas yuav cuam tshuam qhov zoo ntawm cov khoom kawg.Tsis tas li ntawd, cov lim dej ceramic kuj tuaj yeem nqus cov micron loj, thiab txawm tias cov ntxaij lim dej nrog tib lub mesh loj tuaj yeem ua kom pom tseeb qhov tseeb.

Lwm qhov laj thawj tseem ceeb ntawm kev siv cov lim dej ceramic yog lawv lub peev xwmtxo slagthiabtxo qhov paug paughauv molten aluminium.Slag yog ib yam khoom los ntawm cov txheej txheem smelting uas tuaj yeem kis cov hlau molten thiab ua rau muaj qhov tsis xws luag.Los ntawm kev siv lub tshuab lim dej ceramic, cov kev suav nrog no tau txais txiaj ntsig zoo, ua rau kom huv, ua kom zoo dua txhuas ntau dua.

Ceramic ua npuas ncauj lim kuj pom zoo heevthermal shock kuj, cov ntxaij lim dej tuaj yeem tiv taus qhov kub ceev nrawm yam tsis muaj qhov tawg, ua kom muaj kev ruaj khov thiab ua haujlwm ntev thaum lub sijhawm tsim khoom.Tsis tas li ntawd, qhov kev tiv thaiv corrosion tau raug txhim kho, uas txuas ntxiv nws lub neej kev pab cuam, tso cai rau nws kom zoo lim molten aluminium rau lub sijhawm ntev.

Nyob rau hauv cov nqe lus ntawm ntau lawm efficiency, ceramic ua npuas ncauj lim muaj qhov zoo tshaj plaws.Lawv yog tsim los ntawm ib tug automated los ua ke kab system kom ntseeg tau zoo ib yam thiabyog qhov lojspecifications.Tnws lim loj yog qhov tseeb thiab ntau tshaj nrog covlim lub thawv, xyuas kom muaj seamless haum thaum casting.Cov txheej txheem ntau lawm txheej txheem no kuj txuag lub sijhawm.

Zuag qhia tag nrho, daim ntawv thov ntawm ceramic ua npuas ncauj lim hauv txhuas casting muaj ntau yam zoo.Los ntawm cov peev txheej zoo tshaj plaws rau kev muaj peev xwm los txo kev sib kis thiab txhim kho thermal poob siab, cov ntxaij lim dej no ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom lag luam zoo thiab tsis muaj qhov tsis xws luag.Nrog nws cov kab sib dhos tsis siv neeg ntau lawm, qhov loj me thiab kev sib raug zoo nrog cov thawv lim, cov lim dej ceramic ua kom muaj kev ntseeg siab thiab muaj txiaj ntsig zoo rau kev lag luam aluminium casting.
