Gulu la zipangizo zokana kwa ng’anjo yozungulira simenti

1. Pakamwa pamoto 0.6m amapangidwa ndi corundum kuvala zosagwira castable;

Ukoni wakutsogolo wa ng’anjo ya simenti ndi imodzi mwamalumikizidwe ofooka a ng’anjo zambiri zozungulira. Popanga ng’anjo yozungulira, kagwiritsidwe ntchito ka ng’anjoyo kumalepheretsa moyo wautumiki wa ng’anjo yonseyo. Kuphatikiza apo, kupanga batani la ng’anjo ndi ng’anjo yamoto kumakhala kovuta kwambiri. Zomangamanga zoponya nthawi zambiri zimagwiritsa ntchito corundum kuvala zosagwira. Corundum kuvala osamva castable sikungokhala ndi kukana kolimba komanso kukana moto, komanso kumakhala ndi kukana kwamankhwala abwino komanso kukana kugwedezeka kwamafuta. Chofunika kwambiri, ndikosavuta kupanga ndi zotayira zotayira. Zinthu zoterezi zingapangitse moyo wautumiki wa boiler kukhala wosavuta kufutukuka. Kafukufuku akuwonetsa kuti zida zogwiritsira ntchito corundum wear-resistant castable zimakhala ndi moyo wautumiki wopitilira miyezi 8.

1 mita yozizira zone,

Malo osiyanitsa a 5-mita amagwiritsa ntchito njerwa za silicon mullite;

Malo otentha a 21.4-mita amatenga njerwa zotsutsana ndi kugwa za aluminiyamu;

Malo owombera a 25-mita amatenga njerwa ya magnesia chrome;

Malo osinthira a mita 20 amatengera njerwa za spinel; malo ozizira ndi malo osinthira a gawo la 0.8m la ng’anjo ya simenti yatsopano yowuma amatha kusankha njerwa za silicon mullite kapena njerwa zosamva kuvala za HMS.

2. 1m chitsulo CHIKWANGWANI kuvala zosagwira castable pa kamwa ng’anjo

Poyerekeza ndi ng’anjo yachikale yozungulira, kutentha kwa mchira wawung’ono wa ng’anjo nthawi zambiri kumakhala kochepa kuposa 1000 ° C, ndipo kumatha kufika pafupifupi 700 ° C; kutentha kwa mchira waukulu wa ng’anjo kumafika pa 1100 ° C, ndipo mchira wa ng’anjo nthawi zambiri umakhala wopanda khungu. Kwa ma kilns okhala ndi zamchere wambiri kapena malasha ochepa kwambiri pazakudya zosaphika, zinthu monga alkali, sulfure, ndi klorini zimasefukira mobwerezabwereza ndikuwunjikana, zomwe zimapangitsa kuti zigawozo zipangike kutumphuka kwa mchere, potero kumapanga kutumphuka pamadzi. ng’anjo zakuthupi , Zomwe zimakhudza kwambiri kupanga ndi kugwira ntchito pansi pa boiler. Kupyolera mu kuyesera kwathu kosalekeza, m’zaka zaposachedwa, kugwiritsa ntchito zitsulo zosamva kuvala zazitsulo kapena zotayira za aluminiyamu zosamva kuvala muzitsulo zozungulira zidzawongoleredwa bwino.
