Cov txheej txheem tua hluav taws ntawm cov av nplaum ua los ntawm refractory cib manufacturers

Qhuav nruab nrab inlet kub: 150 ~ 200C (tus qauv cib thiab zoo tib yam cib)

120 ~ 160 ℃ (Tshwj xeeb zoo li cib)

Qhov kub thiab txias: 70 ~ 80 ℃

Qhov seem ya raws ntawm cib yog tsawg dua 2%

Lub sij hawm ziab: 16 ~ 24 teev

Kev tua ntawm av nplaum cib tuaj yeem muab faib ua plaub theem

1. Qhov kub ib txwm mus txog 200 degrees Celsius: Lub sijhawm no, qhov kub thiab txias yuav tsum tsis txhob ceev heev los tiv thaiv lub cev los ntawm kev tawg. Thaum tua hluav taws hauv qhov cub, qhov kub ntawm thawj 4 qhov chaw nres tsheb yuav tsum tsis pub tshaj 200 ℃

2, 200 ~ 900C: Nyob rau theem no, cov cua kub yuav tsum tau nce ntxiv los pab txhawb cov tshuaj tiv thaiv ntawm cov organic teeb meem thiab impurities hauv ntsuab.

Nyob rau hauv qhov kub ntawm 600 ~ 900 ℃, qhov muaj zog oxidizing huab cua yuav tsum tau khaws cia hauv qhov cub kom tiv thaiv qhov tshwm sim ntawm “cov tub ntxhais dub” pov tseg.

3, 900 ℃ mus rau qhov kub tshaj plaws tua hluav taws kub: Nyob rau hauv lub siab kub theem, qhov kub thiab txias yuav tsum tau nce tsis tu ncua, thiab txuas ntxiv kom muaj oxidizing huab cua, kom lub cev tsis xws luag yog rhuab sib npaug, thiab tib lub sij hawm, nws kuj tseem tuaj yeem tiv thaiv qhov kub thiab txias. cib los ntawm tawg. Vim hais tias lub sintering shrinkage muaj zog heev tshaj 1100c, tus nqi shrinkage yog siab li 5%, yog li nws yog ib qho tseem ceeb heev kom muaj kev so ntawm qhov kub thiab txias gradient thiab tshem tawm cov kev ntxhov siab sab hauv.

Qhov hluav taws kub tsis kam ntawm av nplaum cib feem ntau yog 100-150C siab tshaj qhov kub ntawm sintering. Yog hais tias qhov kub ntawm sintering ntau yam ntawm sintered av nplaum yog nqaim, lub refractory kub yuav tsum qis dua, nyiam dua nyob ib ncig ntawm 50-100C. Lub sintering kub ntawm av nplaum cib yuav tsum xyuas kom meej tias cov av nplaum ua ke yog tag nrho softened, thiab txheej saum npoo ntawm cov hmoov zoo thiab coarse hais ntawm lub clinker yog tag nrho reacted, thiaj li hais tias cov clinker hais yuav tsum bonded, thiaj li hais tias cov khoom muaj peev xwm muab tau zoo. lub zog thiab ntim stability. Qhov kub ntawm sintering feem ntau yog 1250 ~ 1350c. Thaum cov ntsiab lus ntawm al2o3 siab, sintering kub ntawm cov khoom yuav tsum tau tsim kom tsim nyog, txog 1350 ~ 1380c, thiab lub sij hawm cua sov feem ntau yog 2-10h los xyuas kom meej txaus cov tshuaj tiv thaiv nyob rau hauv cov khoom thiab cov khoom zoo ib yam.

4 Txias theem: Raws li kev hloov pauv ntawm cov av nplaum cib hauv qhov cua txias, qhov cua txias yuav tsum raug txo kom sai thaum qhov kub siab tshaj 800 ~ 1000 ℃, thiab qhov cua txias yuav tsum tau qeeb qis dua 800 ℃. Qhov tseeb, hauv kev tsim khoom tiag tiag, qhov siv cov cua txias tiag tiag yuav tsis ua rau muaj kev pheej hmoo ntawm kev tawg ntawm cov khoom.
