Gabatarwa ga iri da kayan aikin bulogin rufin zafi masu nauyi

Akwai nau’ikan tubali da kayan nauyi da yawa. Ana samar da bulogi masu ɗaukar sauti mai sauƙi a cikin ginin kuma ana sarrafa su ta hanyar fasahar kumfa. A cikin masana’antar refractory, ana kuma kiran bulo-bulo masu nauyi masu ɗaukar nauyi masu ɗaukar zafi, waɗanda ba za su iya ceton kuzari da zafi kawai yadda ya kamata ba Kuma ana iya amfani da su a wani zafin jiki. Bulogin alumina masu nauyi masu nauyi kuma ana san su da bulogin zafin zafi na alumina. Abubuwan da ke cikin alumina ya fi 48%, kuma shi ne mai ɗaukar nauyi mai nauyi wanda ya ƙunshi nau’in mullite da lokacin gilashi ko corundum. Matsakaicin girma shine 0.4 ~ 1.35g/cm3. Porosity shine 66% ~ 73%, kuma ƙarfin matsawa shine 1 ~ 8MPa. Juriya girgiza thermal ya fi kyau.

Tubalin alumina masu nauyi masu nauyi yawanci suna amfani da babban alumina bauxite clinker da ɗan ƙaramin yumbu, bayan an niƙa su da kyau, ana zubar da su a siffa ta hanyar laka ta hanyar samar da iskar gas ko hanyar kumfa, sannan a harba a 1300-1500 ° C. . Wani lokaci ana iya amfani da alumina na masana’antu don maye gurbin ɓangaren bauxite clinker. Ana amfani da shi don rufin rufin rufin rufin rufin katako, da kuma sassan da ba su da lalata da kayan narkakkar zafi mai ƙarfi. Lokacin da ake hulɗa kai tsaye tare da harshen wuta, yanayin hulɗar saman ba zai zama sama da 1350 ° C ba. Ƙunƙashin thermal insulation refractory tubalin sun dace da kewayon zafin jiki na 900 ℃～1650 ℃. Yana da halaye na babban juriya na zafin jiki, ƙarfi mai ƙarfi, ƙarancin ƙarancin zafin jiki, da gagarumin tasirin ceton kuzari.
