Isithando somlilo esingenagesi sinezinga eliphezulu lokuzenzakalela futhi singasebenza ngokuzenzakalelayo uma sisetshenziswa. Kodwa-ke, ukuze siqedele kangcono umsebenzi ngaphansi kokulawulwa okuzenzakalelayo, uhlelo lokulawula okuzenzakalelayo ludinga ukuthola izinga le-vacuum, imingcele yokushisa, imingcele yokusebenza kwenqubo kanye nesimo sokusebenza segumbi lokukhipha igesi, igumbi lokushisa kanye negumbi lokupholisa ukuqinisekisa ukulawulwa kokushisa kwenqubo kwesilinganiso ngasinye sokulawula. Ngokuyinhloko kunezici ezilandelayo:
1. Amapharamitha okuhlola: amanani okushisa amaphuzu amathathu okulinganisa amazinga okushisa ekamelweni lokususa i-oxidation, igumbi lokushisa, kanye negumbi lokupholisa, inani lokucindezela kwesithando somoya, izinga lomoya opholile esithandweni somoya, njll.
2. Isimo sokutholwa: i-alamu yokushisa ngokweqile, i-alamu yokucindezela ngokweqile, i-alamu yokuntuleka kwamanzi, njll. Emakamelweni okushaya ucingo, amakamelo okushisa kanye namakamelo okupholisa.
3. Ukunikezwa kokushisa: Sebenzisa ithuluzi lokulawula izinga lokushisa, bese ulungisa ukunikezwa kwamandla okushisa ukuze ushintshe izinga lokushisa esithandweni somlilo. Sebenzisa i-thermocouple ukuze uhlole izinga lokushisa lesithando somlilo ngasinye, qhathanisa izinga lokushisa lesithando somlilo elitholiwe nezinga lokushisa elidingwa yikhono, bese ubala iphutha. Ithebula lokulawula izinga lokushisa libala ugesi wokushisa webhodi lamandla okushisa elilawulwa inani lokusebenza ngokwemithetho ethile, bese lilawula izinga lokushisa.
4. Ukulawula okukhiphayo: lawula ukuhanjiswa kweloli lokuphakelayo phakathi kwegumbi lokukhipha umoya, igumbi lokufudumeza kanye negumbi lokupholisa, lawula ukusebenza kwephampu yokuhlakazeka, iphampu yeRoots, iphampu yomshini, ivalvu eyinhloko, ivalvu yokubhoboza, ivalvu yangaphambili, njll. Ukuze kufezwe indawo edingekayo ye-vacuum.
Ngemva kokuhlolwa okuhlukahlukene, lapho izimo zokusebenza zihlangabezana nezimo zokulawula, isithando somlilo esingenamsoco singasebenzisa uhlelo lokulawula oluzenzakalelayo ukuze lusebenze, okungaqinisekisa ukuthi lungawuqeda kangcono umsebenzi.
Ngemva kokulungiswa kwesithando somlilo esingenamthungo, kufanele sihlolwe njalo esigabeni sokuqala sokusetshenziswa ukuze kuhlolwe ukuthi izinga lokushisa lobuso elisetshenzisiwe liyahambisana yini nezinga lokushisa langempela esithandweni somlilo (hlola njalo futhi ulinganise igeyiji ye-vacuum, isilawuli sokushisa, i-thermocouple, i-voltmeter kanye ne-ammeter).
Hlola i-heater yezigaba ezintathu ukuthi ayilimele yini ngokushisa ngokweqile, izinga lokushisa elingalingani noma ukuthi imhlophe.
Kuma-vacuum furnace anezinga eliphezulu lokushisa kanye nama-vacuum furnace amelana ne-vacuum, lapho umthamo udlula i-100kW, kufanele kufakwe i-ammeter esigabeni ngasinye kanye nendawo ngayinye yokushisa. Uma izinga lokushisa lemishini kanye nenkomba yemishini kungavamile, kufanele kuhlaziywe futhi kusingathwe ngesikhathi.
Ukuhlola ngemva kokulungiswa kwesithando somlilo esingenamsoco kuwumsebenzi obalulekile. Abasebenzisi kumele banake lapho besisebenzisa, futhi benze umsebenzi omuhle ekuhlolweni okuhlukahlukene ngokuhambisana nezidingo ezifanele.
