Uma sithatha ingilazi entantayo njengesibonelo, izinto ezintathu ezibalulekile ezishisayo ekukhiqizeni ingilazi zihlanganisa isithando somlilo esincibilikisa ingilazi entantayo, ibhavu lethini lengilazi elintantayo kanye nesithando somlilo sengilazi. Enkambweni yokukhiqizwa kwengilazi, isithando somlilo esincibilikisa ingilazi sinesibopho sokuncibilikisa izinto ze-batch zibe uketshezi lwengilazi nokucacisa, ukwenza i-homogenizing kanye nokuzipholisa ezingeni lokushisa elidingekayo ekubumbeni. Ibhavu likathayela liyithuluzi elibalulekile lokubumba ingilazi. Uketshezi lwengilazi olunezinga lokushisa elingu-1050 ~ 1100℃ lugeleza lusuka kumzila wokugeleza luye endaweni ewuketshezi lukathayela kubhavu kathayela. Uketshezi lwengilazi luyisicaba futhi lupholishwe ebusweni bebhavu likathayela, futhi lilawulwa ngokudonsa ngomshini, onogada abaseceleni kanye nemishini yokudweba emaceleni ukuze kwakhiwe iribhoni yengilazi yobubanzi nobugqinsi obudingekayo. Futhi ishiya ibhavu likathayela lapho iphola kancane kancane ibe ngu-600℃ phakathi nenqubo eya phambili. Umsebenzi wesithando somlilo ukuqeda ukucindezeleka okusele kanye ne-optical inhomogeneity yengilazi entantayo, kanye nokuzinzisa ukwakheka kwangaphakathi kwengilazi. Iribhoni yengilazi eqhubekayo enezinga lokushisa elingaba ngu-600℃ elibangelwa ukugeza kathini ingena esithandweni somlilo ngetafula lerola yoshintsho. Yonke le mishini emithathu emikhulu yokushisa idinga izinto eziphikisayo. Ukuze kuqinisekiswe ukusebenza okuvamile nokuzinzile kwesithando somlilo esincibilikisa ingilazi, singenakuhlukaniswa ngempela nokusekelwa kwezinto ezihlukahlukene eziphikisayo. Okulandelayo yizinhlobo ezingu-9 zezinto eziphikisayo ezivame ukusetshenziswa ezithandweni zokuncibilikisa ingilazi nezici zazo:
Izitini ze-silica zokushisa ingilazi:
Izithako eziyinhloko: i-silicon dioxide (SiO2), okuqukethwe kuyadingeka ukuba kube ngaphezu kwama-94%. Izinga lokushisa elisebenzayo: izinga lokushisa eliphakeme kakhulu lokusebenza ngu-1600 ~ 1650 ℃. Izici: ukumelana kahle nokuguguleka kwe-acidic slag, kodwa ukumelana kabi nokuguguleka kwempahla endizayo ene-alkali. Ikakhulu isetshenziselwa ukwakhiwa kwamakhothamo amakhulu, izindonga zamabele nezithando zomlilo ezincane.
Izitini ze-Fire Clay zokokhela ingilazi:
Izithako eziyinhloko: I-Al2O3 ne-SiO2, okuqukethwe kwe-Al2O3 kuphakathi kuka-30% ~ 45%, i-SiO2 iphakathi kuka-51% ~ 66%. Izinga lokushisa elisebenzayo: izinga lokushisa eliphakeme kakhulu lokusebenza ngu-1350 ~ 1500℃. Izici: Kuyinto ebuthakathaka ene-acidic refractory ene-refractoriness enhle, ukuzinza kokushisa kanye nokuhamba okuphansi kwe-thermal. Ikakhulukazi isetshenziselwa ukwakha phansi kwechibi lomlilo, udonga lwechibi lwengxenye yokusebenza kanye nephaseji, udonga, i-arch, izitini zokuhlola eziphansi kanye ne-flue yegumbi lokugcina ukushisa.
Izitini eziphakeme ze-alumina zokushisa ingilazi:
Izingxenye eziyinhloko: I-SiO2 ne-Al2O3, kodwa okuqukethwe kwe-Al2O3 kufanele kube kukhulu kuno-46%. Izinga lokushisa elisebenzayo: Izinga lokushisa eliphakeme lokusebenza ngu-1500 ~ 1650 ℃. Izici: Ukumelana nokugqwala okuhle, futhi kungamelana nokugqwala kusuka kuma-slags ane-acidic kanye ne-alkaline. Isetshenziswa kakhulu emakamelweni okugcina ukushisa, kanye nezinsiza eziphikisayo zamachibi okusebenza, iziteshi zezinto ezibonakalayo kanye neziphakeli.
Izitini ze-Mullite:
Ingxenye eyinhloko yezitini ze-mullite yi-Al2O3, futhi okuqukethwe kwayo cishe ku-75%. Ngenxa yokuthi ikakhulukazi amakristalu e-mullite, ibizwa ngokuthi izitini ze-mullite. Ukuminyana 2.7-3 2g/cm3, porosity evulekile 1% -12%, futhi izinga lokushisa eliphezulu lokusebenza ngu-1500 ~ 1700℃. I-mullite ye-Sintered isetshenziselwa ikakhulukazi ukwakhiwa kwezindonga zegumbi lokugcina ukushisa. I-mullite ehlanganisiwe isetshenziselwa ikakhulukazi ukwakhiwa kwezindonga zamachibi, izimbobo zokubuka, izinqenqema zodonga, njll.
Izitini ezihlanganisiwe ze-zirconium corundum:
Izitini ezihlanganisiwe ze-zirconium corundum zibizwa nangokuthi izitini zensimbi ezimhlophe. Ngokuvamile, izitini ze-zirconium corundum ezihlanganisiwe zihlukaniswa ngamamaki amathathu ngokusho kokuqukethwe kwe-zirconium: 33%, 36%, no-41%. Izitini ze-zirconium corundum ezisetshenziswa embonini yengilazi ziqukethe i-50% ~ 70% Al2O3 kanye ne-20% ~ 40% ZrO2. Ukuminyana kungu-3.4 ~ 4.0g/cm3, i-porosity ebonakalayo ingu-1% ~ 10%, futhi izinga lokushisa eliphezulu lokusebenza lingaba ngu-1700℃. Izitini ezihlanganisiwe ze-zirconium corundum ezinokuqukethwe kwe-zirconium okungu-33% no-36% zisetshenziselwa ukwakha izindonga zechibi lomlilo, izindonga zesifuba sendawo yomlilo, izimbobo ezincane zomlilo womlilo, ama-arches amancane ayisicaba, izitaki ezincane zesithando somlilo, amakhothamo olimi, njll. izimbobo, nezinye izingxenye lapho uketshezi lwengilazi luguguleka futhi lonakalisa izinto eziphikisayo ngobudlova kakhulu. Le nto isetshenziswa kakhulu embonini yengilazi esetshenziswa kakhulu ehlanganisiwe ehlanganisiwe.
Izitini ze-alumina ezihlanganisiwe:
Ngokuyinhloko ibhekisela ezitini ezihlanganisiwe ze-α, β corundum, nezihlanganisiwe ze-β corundum refractory, ezakhiwe ikakhulukazi 92%~94% Al2O3 corundum crystal isigaba, ukuminyana 2.9~3.05g/cm3, porosity okubonakala 1%~10% izinga lokushisa mayelana 17℄ eliphezulu. I-alumina ehlanganisiwe inokumelana okuhle kakhulu nokufakwa kwengilazi futhi cishe akukho nokungcoliswa koketshezi lwengilazi. Isetshenziswa kakhulu odongeni lwechibi lengxenye yokusebenza, phansi kwechibi, ishaneli yokugeleza, udonga lwechibi lwesiteshi sezinto ezisebenzayo, phansi kwechibi lesiteshi nezinye izingxenye zesithando somlilo esincibilikisa ingilazi ezithinta uketshezi lwengilazi futhi ezingadingi ukungcoliswa okuphikisayo.
Izitini ze-quartz:
Ingxenye eyinhloko i-SiO2, equkethe okungaphezu kuka-99%, nokuminyana okungu-1.9~2g/cm3, i-refractoriness engu-1650℃, izinga lokushisa elisebenzayo elicishe libe ngu-1600℃, kanye nokumelana nokuguguleka kwe-asidi. Isetshenziselwa ukwakha udonga lwechibi lwengilazi ye-boron ene-acidic, i-flame space thermocouple hole izitini, njll.
Izinto ze-alkaline refractory:
Izinto ze-alkaline refractory ikakhulukazi zibhekisela ezitini ze-magnesia, izitini ze-alumina-magnesia, izitini ze-magnesia-chrome, nezitini ze-forsterite. Ukusebenza kwayo ukumelana nokuguguleka kwezinto eziqukethe i-alkaline, futhi i-refractoriness yayo ingu-1900 ~ 2000℃. Isetshenziswa kabanzi odongeni olungaphezulu lwe-regenerator yesithando somlilo esincibilikisa ingilazi, i-arch regenerator, umzimba wegridi, kanye nesakhiwo sengxenye yesithando somlilo esincane.
Izitini ze-insulation zeziko lengilazi:
Indawo yokukhipha ukushisa yesithando somlilo esincibilikisa ingilazi inkulu futhi ukusebenza kahle kokushisa kuphansi. Ukuze kongiwe amandla futhi kuncishiswe ukusetshenziswa, inani elikhulu lezinto zokufakelwa liyadingeka ukuze kuhlanganiswe ngokuphelele. Ikakhulukazi, udonga lwechibi, phansi kwechibi, i-arch, kanye nodonga ku-regenerator, ingxenye encibilikayo, ingxenye esebenzayo, njll. kufanele kufakwe insulated ukuze kuncishiswe ukuchithwa kokushisa. I-porosity yesitini sokufakelwa sikhulu kakhulu, isisindo silula kakhulu, futhi ukuminyana akudluli ku-1.3g/cm3. Njengoba ukusebenza kokudlulisa ukushisa komoya kubi kakhulu, isitini sokufakelwa esine-porosity enkulu sinomphumela wokuvikela. I-coefficient yayo ye-thermal conductivity ingaphansi ngokuphindwe izikhathi ezingu-2 ~ 3 kunezinto ezijwayelekile eziphikisayo, ngakho-ke ukukhudlwana kwe-porosity, umphumela wokushisa ungcono. Kunezinhlobo eziningi ezahlukene zezitini zokufakelwa, okuhlanganisa izitini zobumba zobumba, izitini zokushisa i-silica, izitini eziphakeme ze-alumina nokunye.
