I-vacuum furnace inezinga eliphezulu lokuzenzakalela futhi ingasebenza ngokuzenzakalelayo lapho isetshenziswa. Kodwa-ke, ukuze uqedele kangcono umsebenzi ngaphansi kokulawula okuzenzakalelayo, isistimu yokulawula okuzenzakalelayo idinga ukuthola i-vacuum degree, imingcele yokushisa, imingcele yokusebenza yenqubo kanye nesimo sokusebenza segumbi lokususa umoya, igumbi lokushisa kanye negumbi lokupholisa ukuze kuqinisekiswe ukulawulwa kwezinga lokushisa kwenqubo yesithando somlilo ngasinye. lawula ukuphuma. Kukhona ikakhulukazi izici ezilandelayo:
1. Imingcele yokuhlola: amanani okushisa amaphoyinti amathathu wokulinganisa izinga lokushisa ekamelweni le-deoxidation, igumbi lokufudumeza, negumbi lokupholisa, inani lokucindezela kwesithando somlilo, idigri ye-vacuum esithandweni somlilo, njll.
2. Isimo sokutholwa: i-alamu yezinga lokushisa elingaphezulu, i-alamu yokucindezela okukhulu, i-alamu yokushoda kwamanzi, njll. Ezigunjini zokushaya ucingo, ezigunjini zokufudumeza nezokupholisa.
3. Ukunikezwa ukushisa: Sebenzisa ithuluzi lokulawula izinga lokushisa, bese ulungisa amandla okushisa ukuze ushintshe izinga lokushisa esithandweni. Sebenzisa i-thermocouple ukuze usampula izinga lokushisa lesithando somlilo ngasinye, qhathanisa izinga lokushisa elitholiwe nezinga lokushisa elidingwa ikhono, futhi ubale iphutha. Ithebula lokulawula izinga lokushisa libala ukushisa kwamanje kwebhodi lamandla okushisa elilawulwa yinani elisebenzayo ngokwemithetho ethile, bese lilawula izinga lokushisa.
4. Ukukhishwa kokulawula: lawula ukuhanjiswa kweloli lokuphakelayo phakathi kwegumbi lokukhipha umoya, igumbi lokushisa kanye negumbi lokupholisa, lawula isenzo sepompo yokuhlakazeka, Iphampu yezimpande, iphampu yomshini, i-valve eyinhloko, i-valve eqinile, i-valve yangaphambili, njll Ukuze kuzuzwe indawo edingekayo ye-vacuum.
Ngemuva kokuhlolwa okuhlukahlukene, lapho izimo zokusebenza zihlangabezana nezimo zokulawula, isithando somlilo singasebenzisa uhlelo lokulawula okuzenzakalelayo ukuze lusebenze, olungaqinisekisa ukuthi lungakwazi ukuqedela umsebenzi kangcono.
Ngemuva kokuthi isithando somlilo sesilungisiwe, kufanele sihlolwe kaningi esigabeni sokuqala sokusetshenziswa ukuze kubhekwe ukuthi izinga lokushisa elingaphezulu elisetshenzisiwe liyahambisana yini nezinga lokushisa langempela esithandweni somlilo (hlola njalo futhi ulinganise igeji ye-vacuum, isilawuli sokushisa, i-thermocouple, i-voltmeter ne-ammeter).
Hlola i-heater yezigaba ezintathu ukuze uthole umonakalo wokushisa ngokweqile, izinga lokushisa elingalingani noma libe mhlophe.
Ezifusini ze-vacuum ezisezingeni eliphezulu zezigaba ezintathu kanye nezindawo zokumelana ne-vacuum, lapho amandla edlula u-100kW, kufanele kufakwe i-ammeter esigabeni ngasinye kanye nendawo ngayinye yokushisisa. Uma izinga lokushisa lemishini kanye nenkomba yensimbi ingajwayelekile, kufanele ihlaziywe futhi kusetshenzwe ngayo ngesikhathi.
Ukuhlola ngemva kokugcinwa kwesithando somlilo esivalekile kuwumsebenzi obalulekile. Abasebenzisi kufanele banake lapho beyisebenzisa, futhi benze umsebenzi omuhle ekuhloleni okuhlukahlukene ngokuhambisana nezidingo ezifanele.
