Okwangoku, akukho mgangatho wesizwe ocacileyo wokwakhiwa kwee-refractory castables, kodwa kukho imigangatho yokuhlola ecacileyo kunye nemigangatho yokufumanisa izinto ezahlukeneyo eziphikisayo kumgangatho wesizwe we-GB / T kwizinto eziphikisayo.Ungabhekisa kule migangatho ukulinganisa ukwakhiwa kwee-castables.Makhe sithethe ngazo ngokufutshane.
Uninzi lwee-castables zingahlolwa kwaye zivavanywe ngokuhambelana neNdlela yoVavanyo esemgangathweni yesizwe yangoku ye-Thermal Expansion of Refractory Materials (GB/T7320).I-refractory castable lining iya kugalelwa ngokuhambelana nezi zibonelelo zilandelayo:
1. Isiza sokwakha siya kucocwa kuqala.
2. Xa ii-refractory castables zidibana nezitena ezilahlayo okanye iimveliso zokugquma kwe-thermal, amanyathelo okuthintela ukufunxa amanzi aya kuthathwa ukuwahlukanisa.Ngexesha lokwakhiwa, iibhodi ze-foam kunye nelaphu leplastiki zingasetyenziselwa ukuzihlukanisa, kwaye zinokususwa emva kokwakhiwa.
Umenzi ophoswayo uyakukhumbuza ukuba umphezulu wefom esetyenziselwa ukugalela i-furnace lining kufuneka igudiswe, ibe nokuqina okwaneleyo kunye namandla, kunye nokwakhiwa kunye nokususwa kwefomwork kunye nesakhiwo esilula kufuneka sihlangabezane nezi mfuno zilandelayo:
1. Inkxaso iya kufakwa ngokuqinileyo kwaye isuswe ukuze iququzelele ukuvuza komdaka kwindawo edibeneyo.Intsimbi yeplanga egcinelwe ukudibanisa ukwandiswa iya kumiswa ngokuqinileyo ukuphepha ukufuduka ngexesha lokungcangcazela.
2. Kwizinto ezilahlayo ezilahlayo ezinokonakala okuqinileyo okanye ukudityaniswa, umaleko wokwahlula uya kusekwa kwindlela yokwenza ukuze kuthathwe amanyathelo okuthintela ukuhlangana, kwaye ukutenxa okuvumelekileyo komlinganiselo ochanekileyo wesalathiso sobungakanani yi+2~-4mm.Ifom yefom ayiyi kufakwa kwi-castable egalelwe xa amandla ayo engafiki kwi-1.2MPa.
3. I-formwork inokwakhiwa ngokuthe tye kwimigangatho kunye namacandelo okanye kwiibhloko ngezithuba.Ubude bokwakhiwa kweformwork nganye buya kumiselwa ngokwemiba efana nesantya sokugalela sobushushu be-ambient sesiza sokwakha kunye nexesha lokumisela izinto zokusakha.Ngokuqhelekileyo, ayiyi kuba ngaphezu kwe-1.5m.
4. I-formwork yokuthwala umthwalo iya kususwa xa i-castable ifikelela kwi-70% yamandla.I-formwork engathwaliyo imithwalo iya kususwa xa amandla okuphosa anokuqinisekisa ukuba i-furnace lining surface kunye neekona aziyi konakala ngenxa yokudilizwa.Izinto ezishushu neziqinileyo ziya kubhakwa kwiqondo lobushushu elichaziweyo ngaphambi kokususwa.
5. Ubungakanani besithuba, indawo yokusabalalisa kunye nolwakhiwo lokwandiswa kwejoyinti yomlilo odibeneyo womlilo uya kuhambelana nemimiselo yoyilo, kwaye izinto ziya kuzaliswa ngokuhambelana nezibonelelo zoyilo.Xa uyilo aluchazi ubungakanani be-gap yokwandiswa kwe-joint, umyinge wexabiso lokwandiswa kwe-joint kwimitha ye-furnace lining.Umgca wokwandisa umphezulu we-refractory castable castable unokusekwa ngexesha lokugalela okanye ukusika emva kokugalela.Xa ubukhulu bomgca wesithando somlilo bukhulu kune-75mm, ububanzi bomgca wokwandisa kufuneka bube yi-1 ~ 3mm.Ubunzulu kufuneka bube yi-1/3 ~ 1/4 yobukhulu belinen yesithando somlilo.Isithuba somgca wokwandisa kufuneka sibe yi-0.8 ~ 1m ngokwemilo yomthombo.
6. Xa ubukhulu be-insulating refractory castable lining ≤ 50mm, indlela yokwaleka ngesandla ingasetyenziselwa ukugalela okuqhubekayo kunye ne-tamping manual.Emva kokuthulula, umgangatho we-lining kufuneka ube tyaba kwaye uxineke ngaphandle kokupolisha.
Ukutyeba kokukhanya kwe-refractory castable lining δ< 200mm, kunye neendawo ezithambekele kwi-furnace surface engaphantsi kwama-60 zingagalelwa ngesandla.Xa ugalela, uya kuhanjiswa ngokulinganayo kwaye ngokuqhubekayo ugalelwe.Ihamile yerabha okanye isando somthi siya kusetyenziswa ukuhlanganisa iindawo ngehamile enye kunye nesiqingatha sehamile kwimilo yeplum.Emva kokuxinwa, i-vibrator yepleyiti ephathekayo iya kusetyenziselwa ukungcangcazela kunye nokudibanisa i-furnace surface.Umphezulu welinen yesithando somlilo uya kuba mcaba, uxinene kwaye ungabi namasuntswana akhululekileyo.
