Txhim kho Casting Nto Zoo
Dawb fused aluminayog dav siv nyob rau hauv lub foundry kev lag luam vim hais tias nws muaj peev xwm ua tau zoo txhim kho cov nto tiav ntawm castings. Nrog rau siab hardness, zoo heev hnav tsis kam, thiab ruaj khov chemical zog, dawb fused alumina pab txo qhov tsis xws luag, xuab zeb adhesion, thiab roughness thaum lub sij hawm casting txheej txheem. Nws kuj tseem txhim kho lub plhaub lub zog thiab qhov tseeb qhov tseeb, ua rau nws haum rau precision casting daim ntaub ntawv.
Nyob rau hauv xyoo tas los no, ntau lub tuam txhab nyob hauv Europe thiab Amelikas tau maj mam txo kev siv zirconium silicate thiab pib siv dawb fused alumina ua cov khoom siv plhaub. Piv nrog cov ntaub ntawv zircon, dawb fused alumina muab kev ruaj khov zoo thiab txhim khu kev qha zoo nyob rau hauv siab - qhov kub thiab txias, pab tsim cov khoom zoo nkauj thiab huv si.
High Purity Thiab Refractory Performance
Qhov zoo ntawm dawb fused alumina feem ntau nyob ntawm nws cov purity. Cov impurities feem ntau suav nrog SiO2, Fe2O3, thiab TiO2. Cov ntsiab lus qis impurity thiab siab dua Al2O3 cov ntsiab lus feem ntau qhia tau hais tias zoo dua, muaj zog durability, thiab txhim kho refractory kev ua tau zoo.
Dhau li ntawm daim ntawv thov abrasive, dawb fused alumina kuj tau siv dav los ua cov khoom siv refractory vim nws qhov siab melting point thiab thermal stability. Txawm li cas los xij, cov impurities ntau dhau tuaj yeem txo nws txoj kev tiv thaiv rau qhov kub thiab txias thiab cuam tshuam rau lub neej kev pab cuam. Yog li ntawd, siab -purity dawb fused alumina yog qhov kev xaiv zoo tshaj plaws rau kev tsim khoom thiab kev lag luam refractory.
