Mfundo zoyenera kutsatiridwa posankha njerwa zaumbali za mafakitale kilns

Pali mitundu yambiri ya ma kilns a mafakitale ndipo mapangidwe ake ndi ovuta kwambiri. Pakati pawo, kusankha ndi kugwiritsa ntchito njerwa zotsutsa nthawi zambiri zimakhala zosiyana kwambiri. Ziribe kanthu kuti ndi mtundu wanji wa njerwa zowonongeka zomwe zimasankhidwa kuti ziwotchere mafakitale, ziyenera kukwaniritsa zofunikira izi: choyamba, zimatha kupirira kutentha kwakukulu popanda kufewetsa ndi kusungunuka, komanso ziyenera kupirira kutentha kwakukulu. Simataya mphamvu ya mkati mwa njerwa zomangira njerwa, sichimapunduka, imakhala ndi kukhazikika kwa kutentha kwapamwamba kwambiri, imakhala ndi kusintha kwa mzere wowotcha pang’ono, ndipo imatha kukana kukokoloka kwa mpweya wotentha kwambiri komanso kukokoloka kwa slag. Kukula kwa njerwa zokanira ndizokhazikika, ndipo mbali zenizeni za ng’anjo ziyenera kutsimikiziridwa ndi momwe zilili.

Mfundo zomwe ziyenera kutsatiridwa posankha njerwa zowotchera mafakitale:

1. Choyamba, tiyenera kumvetsa makhalidwe a ng’anjo mafakitale, kusankha refractory njerwa malinga ndi mapangidwe ng’anjo, malo ogwira ntchito ndi zikhalidwe ntchito gawo lililonse, ndi kusanthula kuwonongeka limagwirira wa refractory njerwa ntchito mu ng’anjo mafakitale kukwaniritsa. chandamale Sankhani njerwa refractory. Mwachitsanzo, refractory njerwa kwa ladle, chifukwa chitsulo chosungunuka zili mu ladle ndi zamchere, chitsulo chosungunula akukumana kukokoloka kwa thupi ndi kukokoloka kwa mankhwala pamene anatsanulira mu ladle, ndi matenthedwe kupsyinjika chifukwa cha mwadzidzidzi kutentha kusintha. Nthawi zambiri, njerwa za magnesia-carbon refractory zolimbana bwino ndi kukokoloka kwa slag zimagwiritsidwa ntchito ngati ladleyo imakutidwa ndi zomangamanga.

2. Kuti mumvetse zomwe zimapangidwira njerwa zowonongeka, dziwani bwino za zinthu ndi makhalidwe a njerwa zowonongeka, monga momwe zimakhalira ndi mchere wa mineral, katundu wakuthupi ndi ntchito zogwirira ntchito zopangira njerwa zomwe zimagwiritsidwa ntchito mu njerwa zowonongeka, ndipo perekani kusewera kwathunthu ku ubwino. za refractory yaiwisi yaiwisi osankhidwa kwa njerwa refractory , Pambuyo kasinthidwe wololera wa refractory yaiwisi yaiwisi chilinganizo, njerwa refractory ndi ntchito bwino.

3. Yang’anirani moyenerera ntchito yonse ya ng’anjo. Magawo osiyanasiyana a ng’anjo amakhala ndi malo osiyanasiyana ogwirira ntchito komanso momwe amagwirira ntchito. Njerwa zotsutsidwa zosankhidwa ziyeneranso kufananizidwa bwino. Onetsetsani kuti sipadzakhala zochita za mankhwala ndi kuwonongeka kusungunuka pakati pa njerwa refractory wa zipangizo zosiyanasiyana mu malo otentha kutentha, ndi kuonetsetsa kuti mbali zonse za ng’anjo akalowa Kusamala imfa ya ng’anjo, momveka kulamulira ntchito yonse ya ng’anjo, kuonetsetsa moyo wonse wautumiki wa ng’anjo, ndikupewa kukonzanso kosiyanasiyana kwa mbali zosiyanasiyana za ng’anjo.

4. Njerwa zokanira zowotchera mafakitale siziyenera kungokwaniritsa zofunikira kuti zigwiritsidwe ntchito, komanso kulingalira zanzeru za phindu lazachuma. Ngati njerwa zadothi zimatha kukwaniritsa zosowa za mafakitale a mafakitale, palibe chifukwa chosankha njerwa za alumina yapamwamba. Choncho, kusankha njerwa zokanira zopangira mafakitale ziyenera kuganiziridwa mozama.
