Babban zafin jiki mai jurewa bulo don Kilns, tanderu

Dangane da sassa daban-daban na tubalin da ke hana ruwa gudu, ana iya raba su zuwa rukuni biyar, wato: tubalin siliki-alumina jerin tubalin, tubalin da ke ɗauke da sinadarin alkaline, tubalin da ke ɗauke da carbon, bulogin da ke ɗauke da zirconium, da bulogin da ke hana zafi.

Duk wani tanderun da aka gina ba a gina shi da nau'in tubali guda ɗaya kawai ba, yana buƙatar haɗuwa da tubali daban-daban.

(1) tubalin silica suna nufin tubalin da ke ɗauke da fiye da 93% SiO2, waɗanda sune manyan nau'ikan tubalin acid.Ana amfani da shi galibi don tanda na coke na masonry, amma kuma don rumbun adana kaya da sauran sassa masu ɗaukar nauyi na kilns ɗin zafin jiki na gilashin daban-daban, yumbu, na'urorin ƙarfe na carbon, da bulo mai ɗaukar nauyi.Ana amfani dashi a cikin kayan aikin thermal da ke ƙasa da 600 ° C kuma tare da manyan canjin zafin jiki.

(2) Tukar laka.Tubalin yumbu sun ƙunshi mullite (25% zuwa 50%), lokacin gilashin (25% zuwa 60%), da crristobalite da quartz (har zuwa 30%).Yawancin lokaci, ana amfani da yumbu mai wuya a matsayin albarkatun kasa, clinker yana calcined a gaba sannan a haɗe shi da yumbu mai laushi.Hakanan za'a iya ƙara ƙaramin gilashin ruwa, siminti, da sauran abubuwan ɗaure don yin samfuran da ba a ƙone ba da kayan da ba su da siffar.Bulo ne da aka saba amfani da shi a cikin tanderun fashewa, murhu mai zafi, tanda mai dumama, tukunyar wuta, kiln na lemun tsami, kilns na jujjuya, yumbu, da kiln bulo mai jujjuyawa.
(3) Maɗaukakin bulogin alumina.Abubuwan da ke cikin ma'adinai na bulogin alumina masu ɗorewa shine corundum, mullite, da matakan gilashi.Danyen kayan yana da babban alumina bauxite da sillimanite na halitta, kuma akwai kuma gauraye corundum, sintered alumina, roba mullite, da clinker calcined tare da alumina da yumbu a daban-daban rabbai.Mafi yawa ana samar da shi ta hanyar sintering.Amma samfuran kuma sun haɗa da tubalin simintin gyare-gyare, daɗaɗɗen bulo, bulogin da ba a ƙone ba, da bulogin da ba su da siffa.High alumina refractory tubalin ana amfani da ko'ina a cikin baƙin ƙarfe da karfe masana'antu, wadanda ba na ƙarfe karfe masana'antu, da sauran masana'antu.(4) Bulogin corundum, tubalin corundum suna nufin wani nau'in tubalin da ke da abun ciki na AL2O3 wanda bai wuce 90% ba da kuma corundum a matsayin babban lokaci, wanda za a iya raba shi zuwa tubalin corundum da aka yi da shi da kuma tubalin corundum mai hade (5) High- alumina zafi-insulating haske-nauyi refractory tubalin.Shi bulo ne mai ɗaukar haske mai rufewa tare da bauxite azaman babban abun ciki na AL2O3 wanda bai gaza 48% ba.Tsarin samarwa yana ɗaukar hanyar kumfa, kuma ana iya amfani da hanyar ƙari na ƙonewa.Za'a iya amfani da tubalin mai ɗaukar nauyi mai ƙarfi-alumina mai ɗaukar zafi don gina yadudduka masu hana zafi da wuraren da babu ƙaƙƙarfan narkakkar kayan abu mai zafi da zazzagewa.Lokacin a kai tsaye lamba tare da harshen wuta, da surface lamba zafin jiki na general high-alumina zafi-insulating refractory tubalin ba zai zama mafi girma fiye da 1350 ℃.Mullite zafi-insulating tubali iya kai tsaye tuntuɓar harshen wuta kuma suna da halaye na high-zazzabi juriya, high ƙarfi, da kuma ban mamaki makamashi-ceton sakamako.Ya dace da rufin tanderun pyrolysis, tanderun fashewa mai zafi, yumbu na yumbu, kiln aljihun aljihun lantarki, da tanderun juriya iri-iri.(6) Tulle mai ɗaukar zafi mai ɗaukar nauyi mai ɗaukar nauyi bulogi ne masu ɗaukar zafi tare da abun ciki na AL2O3 na 30% zuwa 48% wanda aka yi da yumbu mai jujjuyawa azaman babban albarkatun ƙasa.Tsarin samar da shi yana ɗaukar hanyar ƙonawa tare da hanyar halaye da hanyar kumfa.Yin amfani da yumbu mai jujjuyawa, beads masu iyo, da ƙwanƙwasa yumbu kamar kayan albarkatun ƙasa, ƙara ɗaure da sawdust, ta hanyar batching, haɗawa, gyare-gyare, bushewa, da harbe-harbe, ana samun samfurin tare da babban yawa na 0.3 zuwa 1.5g/cm3.Fitar da tubalin da ke hana zafin yumbu ya kai fiye da rabin jimlar bulogin da ke hana zafi.
