Kunezinhlobo eziningi zezinto eziphikisayo ezisetshenziswa kuhhavini we-coke, futhi impahla ngayinye inezimo zayo zokusebenza eziqondile kanye nezidingo zokusebenza. Okulandelayo yizinto ezivame ukusetshenziswa eziphikisayo kuhhavini we-coke kanye nezinyathelo zabo zokuphepha:
1. Izinto ezivame ukusetshenziswa eziphikisayo kumahhavini e-coke
Izitini ze-silicon
Izici: ukumelana nezinga lokushisa eliphezulu (ngaphezulu kuka-1650 ℃), ukumelana nokugqwala kwe-asidi, nokuzinza okuhle kokushisa.
Isicelo: Isetshenziswa kakhulu ezindaweni ezinokushisa okuphezulu njengegumbi elivuthayo, igumbi le-carbonization, kanye nephezulu yesithando somlilo kuhhavini we-coke.
Izinyathelo zokuzivikela:
Izitini ze-silicon zijwayele ukuguqulwa kwekristalu ngaphansi kuka-600 ℃, okuholela ekushintsheni kwevolumu, ngakho-ke kufanele zigwenywe ezindaweni ezinezinga lokushisa eliphansi.
Ngesikhathi sokwakhiwa, izinsimbi zezitini kufanele zilawulwe ngokuqinile ukuze kuvinjelwe ukunwetshwa kwezinsimbi zezitini emazingeni okushisa aphezulu.
Izitini eziphezulu ze-alumina
Izici: i-refractoriness ephezulu (ngaphezulu kuka-1750 ℃), ukumelana nokushaqeka okuhle kokushisa, nokumelana nokugqwala okuqinile.
Isicelo: Isetshenziswa odongeni lwesithando somlilo, phansi kwesithando somlilo, igumbi lokugcina ukushisa nezinye izingxenye ze-oven coke.
Izinyathelo zokuzivikela:
Izitini eziphezulu ze-alumina zinokumelana okubuthakathaka nokugqwala kwe-alkali futhi zidinga ukugwema ukuthintana okuqondile nezinto ze-alkali.
Ngesikhathi sokwakhiwa, ukunakwa kufanele kukhokhwe ekomisweni nasekubhakeni komzimba wezitini ukuvimbela ukuqhekeka.
Isitini sobumba somlilo
Izici: ukumelana nokushisa okuhle, izindleko eziphansi, ukumelana nokushaqeka okuhle kokushisa.
Isicelo: isetshenziswa ezindaweni ezisezingeni eliphansi ezifana ne-flue ye-oven coke kanye nengxenye engezansi yegumbi lokugcina ukushisa.
Amanothi:
I-refractoriness yezitini zobumba iphansi futhi ayifaneleki ezindaweni ezishisa kakhulu.
Naka ubufakazi bomswakama ukuze ugweme ukulahlekelwa amandla ngemva kokumuncwa kwamanzi.
Isitini seMagnesium
Izici: i-refractoriness ephezulu kanye nokumelana okuqinile nokuguguleka kwe-alkali.
Isicelo: esetshenziswa phansi kanye esithandweni somlilo we-coke nezinye izingxenye ezihlangana nezinto ezine-alkali.
Amanothi:
Izitini zeMagnesium zimunca amanzi kalula futhi zidinga ukugcinwa kahle ukuze zigweme umswakama.
I-coefficient yokwandisa okushisayo yezitini ze-magnesium inkulu, futhi kufanele kunakwe izinkinga zokushaqeka kokushisa.
Izitini ze-silicon carbide
Izici: izinga eliphezulu le-thermal conductivity, ukumelana nokugqoka, nokumelana nokushaqeka okuhle kakhulu kokushisa.
Isicelo: isetshenziswe emnyango wesithando somlilo, ikhava yomlilo, i-burner nezinye izingxenye ze-coke oven ezidinga ukuchithwa kokushisa okusheshayo.
Amanothi:
Izitini ze-silicon carbide ziyabiza futhi zidinga ukukhethwa ngokufanele.
Gwema ukuthintana namagesi e-oxidizing aqinile ukuze uvimbele ukubola.
Ama-castable aphikisayo
Izici: ukwakhiwa okulula, ubuqotho obuhle, nokumelana nokushaqeka okuhle kakhulu kwe-thermal.
Isicelo: Isetshenziselwa ukulungisa i-oven ye-coke, izingxenye zomumo oyinkimbinkimbi kanye nokuphonsa okubalulekile.
Amanothi:
Inani lamanzi elengeziwe ngesikhathi sokwakhiwa kufanele lilawulwe ngokuqinile ukuze ligweme ukuthikameza amandla.
Izinga lokushisa kufanele liphakanyiswe kancane ngesikhathi sokubhaka ukuvimbela ukuqhekeka.
I-fiber refractory
Izici: isisindo esilula, ukufakwa kahle kwe-thermal, nokumelana nokushaqeka okuhle kakhulu kwe-thermal.
Isicelo: Isetshenziselwa ungqimba lokufakwa kwamahhavini we-coke ukunciphisa ukulahlekelwa ukushisa.
Amanothi:
Imicu ye-Refractory ayimelani nomthelela wemishini futhi idinga ukugwenywa ekulimaleni kwangaphandle.
Ukuncipha kungase kwenzeke ngaphansi kwamazinga okushisa esikhathi eside futhi kudinga ukuhlolwa njalo.
Izitini ze-Corundum
Izici: i-refractoriness ephezulu kakhulu (ngaphezu kuka-1800°C) nokumelana nokugqwala okuqinile.
Isicelo: Isetshenziswa ezindaweni ezishisa kakhulu nezinokuguguleka okuphezulu kwamahhavini ama-coke, njengendawo eseduze nezimbawula.
Izinyathelo zokuzivikela:
Izitini ze-Corundum ziyabiza futhi zidinga ukukhethwa ngokufanele.
Nakani ukuhlangana kwezitini zezitini ngesikhathi sokwakhiwa.
2. Izinyathelo zokuqapha zokusetshenziswa kwezinto eziphikisayo ze-coke oven
Ukukhetha okubalulekile
Khetha izinto eziphikisayo ngokufanelekile ngokuya ngezinga lokushisa lezingxenye ezihlukene zehhavini ye-coke, imidiya ebolayo (i-asidi noma i-alkaline) kanye nomthwalo wemishini.
Gwema ukusebenzisa izinto eziphikisayo ezinezinga lokushisa eliphansi ezindaweni ezinezinga lokushisa eliphezulu ukuze uvimbele ukwehluleka kokubalulekile.
Ikhwalithi yokwakha
Lawula ngokuqinile ubukhulu bezitini ezihlangene futhi usebenzise udaka olufanele oluphikisayo ukuze uqinisekise ukuminyana kokwakhiwa kwamatshe.
Kuma-castables aphikisayo, ukwakhiwa kufanele kwenziwe ngokwesilinganiso ukuze kugwenywe ukungezwa kwamanzi ngokweqile okuthinta amandla.
Ukusebenza kokubhaka kuhhavini
Ama-oven ama-coke asanda kwakhiwa noma alungiswayo adinga ukubhakwa. Izinga lokushisa kufanele liphakanyiswe kancane ngesikhathi sokubhaka ukuze kugwenywe ukuqhekeka noma ukuxebuka kwezinto eziphikisayo ngenxa yokushintsha kwezinga lokushisa okungazelelwe.
Isondlo sansuku zonke
Njalo hlola ukuguga, ukuguguleka kanye nokuqhekeka kwezinto eziphikisayo ze-coke oven futhi uzilungise ngesikhathi.
Gwema ukusebenza okungaphezu kwezinga lokushisa kwamahhavini e-coke ukuze uvimbele ukulimala ngaphambi kwesikhathi ezintweni eziphikisayo.
Isitoreji nokulondolozwa
Izinto eziphikisayo kufanele zigcinwe endaweni eyomile ukuze kugwenywe umswakama (ikakhulukazi izitini ze-magnesia kanye ne-refractory castables).
Izinto eziphikisayo zezinto ezihlukene kufanele zigcinwe ngokuhlukana ukuze kuvinjelwe ukudideka.
Isifinyezo
Izinto ezisetshenziswayo ezivame ukusetshenziswa kuhhavini we-coke zifaka izitini ze-silica, izitini eziphakeme ze-alumina, izitini zobumba, izitini ze-magnesia, izitini ze-silicon carbide, izinsimbi eziphikisayo, ama-refractory fibers kanye nezitini ze-corundum. Lapho usebenzisa, izinto zokwakha kufanele zikhethwe ngokuvumelana nezimo ezithile zokusebenza, futhi kufanele kukhokhwe izinga lokwakha, ukusebenza kwehhavini nokugcinwa kwansuku zonke ukuze kwandiswe impilo yenkonzo ye-coke oven.
