Lub teeb hnyav hluav taws kub av nplaum rwb thaiv tsev cib

Lub teeb Ntsuas Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob yog ua kom muaj qhov kub nyob hauv zos, uas muaj txawm lub zog loj, siab thermal conductivity thiab neeg impurity. Qhov kub ntawm 1200-1400 ℃. Cov khoom xyaw yog tov nrog dej ua los ntawm cov khoom yas los yog av nkos, av nkos nrog extrusion los yog pouring zoo, 1250-1350 ℃ tom qab qhuav hlawv oxidation cua. Qhov ntim ceev ntawm cov av nplaum siv feem ntau yog 0.75-1.2 g / / cm3. Nws yog ib qho tseem ceeb ntawm refractory rau kev txuag hluav taws xob thiab kev txuag kub. Lub teeb yuag av nplaum rwb thaiv tsev cib tuaj yeem siv rau hauv qhov cub ntawm cov hlau thiab hlau ua, cov hlau tsis muaj hlau, cov khoom siv hauv tsev, kev lag luam hluav taws xob, thiab lwm yam.

Cim:
1. Tsis tshua muaj hlau thiab lwm yam impurities,
2.High refractoriness,
3.High porosity, tsawg ntim ceev,
4.Zoo kub insulating nyhuv thiab lub zog txuag,
5.Zoo thermal shock stability,
6.Corrosion thiab yaig kuj.
