7. Lwm Cov Kev Kho Kom Haum:Kev kho qhov chaw, qhov kawg qauv, cov khoom siv tshwj xeeb piv rau cov xwm txheej hnyav.
Cov yam ntxwv ntawm cov khoom:
1. Kev Tiv Thaiv Kub Siab Zoo heev:Qhov kub ua haujlwm siab tshaj plaws txog li 1600 ℃, refractoriness ≥1750 ℃, ruaj khov ntawm qhov kub siab yam tsis muaj deformation; kev ruaj khov thermal txhim khu kev qha heev thiab kev tiv thaiv thermal zoo heev rau cov khoom raug hlawv txog li 1400 ℃.
2. Kev Nyuaj Siab & Kev Hnav Tsis Zoo:Rockwell hardness HRA80-90 (qhov thib ob tsuas yog pob zeb diamond), Mohs hardness ≥9; hnav tsis kam yog 266 npaug ntawm manganese hlau thiab 171.5 npaug ntawm high-chromium cam khwb cia hlau, ntev lub neej khoom siv tsawg kawg yog kaum npaug thiab txo lub sijhawm tsis ua haujlwm thiab cov nqi.
3. Kev Ruaj Ntseg Zoo Tshaj Plaws ntawm Thermal Shock:Kev nthuav dav thermal qis, tiv taus cua sov / txias sai, tsis yooj yim tawg.
4. Kev Ruaj Ntseg Tshuaj Zoo:Acid/alkali/glaze corrosion-resistant, tsis muaj kuab paug rau cov khoom ua tiav.
5. Qhov Nto du & Qhov Tseeb Siab:Precision-av (Ra ≤1.6μm), kev ua haujlwm ruaj khov, tsis muaj khawb (qhov tseeb tuaj yeem hloov kho tau).
6. Lub Teeb thiab Txuag Hluav Taws Xob:Qhov ceev 3.5–3.8 g/cm³ (3.6 g/cm³ ua tus qauv, tsuas yog ib nrab ntawm cov hlau), txo cov khoom siv hnyav thiab ua kom lub neej khoom siv ntev dua.
