Kodi njerwa yopumira ndi chiyani

Njerwa ya ladle yomwe imatha kuloleza mpweya ndi chinthu chatsopano chokhala ndi moyo wautali, kupulumutsa mphamvu ndi kuchepetsa kugwiritsidwa ntchito, ndi kapangidwe kake koyenera, kukhazikika kwamatenthedwe, kukana kukokoloka kwa nthaka, kukana kukokoloka kwa nthaka, komanso kukana kwamphamvu, kuthamanga kwambiri, ntchito yotetezeka komanso yodalirika, ndi moyo wautali wa utumiki Dikirani miniti. Amagwiritsidwa ntchito kwambiri pakupanga zitsulo, m’munsi ndi mbali zina.

Kupititsa patsogolo ndikugwiritsa ntchito ladle ya corundum-spinel njerwa zopumira ya ladle yayikulu yoyengedwa: Kuti mukwaniritse zofunikira za ladle lalikulu loyenga ladle la njerwa zopumira, kudzera munjira zaluso monga kukhathamiritsa kwa fomula ndikuwombera kotentha kwambiri, zotsatira zake ndikugwiritsa ntchito zakonzedwa bwino. Njerwa ya corundum-spinel yopumira ya njerwa zachikhalidwe za chromium corundum. Njerwa yopumira imapangidwa ndi mbale corundum ngati zinthu zophatikizika, yophatikiza yoyera corundum ngati ufa wosalala, ndikuwonjezera simenti 6% ya calcium aluminate simenti, 5% Active α-Al2O3 micropowder ndi 8% spinel, kuphatikiza kuchuluka kwa oxide ya chromium ndi kuchepetsa madzi wothandizila, atatha kugwedera kupanga, kuyanika, kuteteza kutentha kwa 1630 ° C kwa maola opitilira 3. Njerwa yololeza yololeza yomwe imagwiritsidwa ntchito imagwiritsidwa ntchito pa ladle lalikulu loyenga kuti mupeze zipatso zokhutiritsa.

Ladle pansi argon ikuwomba ladle mpweya wokwera wokwera njerwa amatenga zida zoyera zofananira, masanjidwewo amaphatikizidwa kale ndikusakanikirana, ndipo zina zopangira zimatumizidwa mwachindunji kuchokera kunja, kugawa koyenera, ndikupanga mosamalitsa molingana ndi zofunikira zapamwamba zapadziko lonse lapansi. Chogulitsidwacho chili ndi zabwino zamphamvu kwambiri, kukokoloka kwa kukokoloka, kukana kukokoloka, kulowerera mkati, komanso moyo wautali.

■ Zizindikiro zazikulu zakuthupi ndi zamankhwala za mankhwala: Al2O3% -95.0 Cr2O3% ≥3.0, porosity yooneka:% ≤16.0, kuchuluka kochulukirapo: g / cm3 -3.20, kutentha kwabwino mphamvu: MPa 110 ° C ≥60.0, 1500 ° C Mitundu: 100.0, 1600 ° C ≥120.0. Kutentha kwamphamvu kwamphamvu: MPa 1400 ° C, 30min -10.0.

■ Gwiritsani ntchito gawo: kumenyera pansi kwa ladle.

■ Njira yomanga: paka matope amoto wogawana pamtunda, ndikukhazikitsa sikukhazikika.
