Titanium thiab titanium alloys qhia cov txiaj ntsig zoo hauv kev ua yeeb yam, raws li lawv muaj peev xwm tsim cov qauv zoo nkauj ncaj qha, yog li zam cov khoom siv cov txheej txheem ntau. Cov xeeb ceem no tso cai rau titanium thiab titanium alloys kom ua tiav cov khoom siv tau siv tau txog 45% rau 90% rau precision castse. Qhov no yog undoubtedly ib qho loj dua rau tus kuj muaj nqi titanium thiab titanium alloys, uas tuaj yeem txo cov nqi tsim khoom thiab txhim kho kev lag luam kev lag luam thiab txhim kho kev lag luam ua haujlwm.
Txawm li cas los xij, cov txheej txheem casting ntawm titanium alloys tsis yooj yim. Raws li titanium alloy nyob rau hauv lub xeev Molten muaj kev ua si ntau heev, tuaj yeem ua rau txhua yam khoom siv refractory thiab gases, uas nce rau qhov nyuaj ntawm kev ua pov. Yog li ntawd, txoj kev cov nyom ntsib kev txhim kho ntawm cov txheej txheem casting rau titanium alloys muaj ntau dua li cov hlau, txhuas, magnes thiab lwm yam hlau.
Txhawm rau kom ntseeg tau tias titanium alloys tsis hnov mob nrog cov khoom siv refractory thiab gases nyob rau hauv cov txheej txheem casting, lawv cov kev sib tshooj yuav tsum tau nqa tawm hauv cov xwm txheej nruj. Tshwj xeeb, yaj thiab nchuav ntawm titanium alloys yuav tsum tau ua tiav nyob rau hauv kev tiv thaiv roj lossis hauv lub tshuab nqus ib puag ncig. Qhov no zoo cais cov titanium alloy los ntawm gases xws li oxygen xws li cov ntaub ntawv refractory, yog li zam kev tsis tsim nyog siv tshuaj.
Txhawm rau ua kom tiav qhov kev xav tau no, feem ntau siv CASTING cov khoom siv suav nrog cov tshuab nqus tshuaj ntawm kev siv tshuaj txhuam tus kheej Arc Plhaub cov cub tawg. Cov cuab yeej no tuaj yeem muab cov kev tiv thaiv hluav taws xob ib puag ncig lossis cov roj av ua kom muaj kev nyab xeeb thiab ua tau zoo ntawm titanium alloys nyob rau hauv lub melanium alloys nyob rau hauv lub yaj thiab pouring txheej txheem. Ib qho ntxiv, tooj liab crucaibles nrog tau yuam kev txias yuav tsum siv nyob rau hauv cov txheej txheem casting. Tooj liab cruciles muaj zoo thermal conductivity thiab corrosion tsis kam thiab tuaj yeem tiv thaiv lub siab thiab tshuaj lom neeg cov roj melts. Nyob rau hauv kev sib piv, crucibles ua los ntawm cov khoom siv refractory tsis tuaj yeem tiv taus cov tshuaj lom neeg ntawm Titanium yaj thiab yog li tsis tuaj yeem siv rau Casting Titanium alloys.
Hauv cov ntsiab lus, cov txheej txheem ntawm melting thiab casting titanium alloys nthuav tawm cov cai tshwj xeeb cov cai thiab cov nyom. Txhawm rau kom ua tau zoo thiab ua tau zoo ntawm titanium alloys, ntsuas nruj yuav tsum tau ua kom tsis txhob muaj cov khoom siv refactory thiab roj av. Nyob rau yav tom ntej, nrog kev nce qib txuas ntxiv ntawm science thiab thev naus laus zis thiab kev txhim kho cov thev naus laus zis txuas ntxiv, peb yuav tsum ua kom muaj kev sib tw thiab kev nce qib.
