I-vacuum furnace inezinga eliphezulu lokuzenzekelayo kwaye inokusebenza ngokuzenzekelayo xa isetyenziswa. Nangona kunjalo, ukuze ugqibezele kakuhle umsebenzi phantsi kolawulo oluzenzekelayo, inkqubo yokulawula ngokuzenzekelayo kufuneka ibone iqondo le-vacuum, imilinganiselo yokushisa, imilinganiselo yokusebenza kwenkqubo kunye nesimo sokusebenza kwegumbi lokukhupha, igumbi lokufudumeza kunye negumbi lokupholisa ukuqinisekisa ukuba inkqubo yokulawula ukushisa kwesithando somlilo ngasinye. imveliso yolawulo. Kukho ikakhulu le miba ilandelayo:
1. Iiparamitha zokuvavanya: amaxabiso okushisa amanqanaba amathathu okulinganisa amaqondo okushisa kwigumbi le-deoxidation, igumbi lokufudumeza, kunye negumbi lokupholisa, ixabiso loxinzelelo lwesithando somlilo, i-vacuum degree kwisithando somlilo, njl.
2. Ubume bokubona: i-alamu yobushushu obugqithisileyo, i-alamu yoxinzelelo, i-alamu yokunqongophala kwamanzi, njl. Kumagumbi okufowunela, amagumbi okufudumeza kunye namagumbi okupholisa.
3. Ukunikezelwa kokushisa: Sebenzisa isixhobo sokulawula ubushushu, uze ulungelelanise ukunikezelwa kwamandla okufudumeza ukutshintsha ubushushu kwisithando somlilo. Sebenzisa i-thermocouple ukuvavanya ubushushu beziko ngalinye, thelekisa iqondo lokushisa elifunyenweyo kunye nobushushu obufunwa ngubuchule, kwaye ubale impazamo. Itheyibhile yokulawula ukushisa ibala ukufudumeza kwangoku kwebhodi yamandla okufudumala elawulwa ngumthamo wokusebenza ngokwemigaqo ethile, kwaye emva koko ilawula ukushisa.
4. Ukulawulwa kwemveliso: lawula ukuhanjiswa kwelori yokutya phakathi kwegumbi lokukhupha, igumbi lokufudumeza kunye negumbi lokupholisa, lawula isenzo sepompo yokusabalalisa, ipompo yeengcambu, ipompo yomatshini, i-valve engundoqo, i-valve ephazamisayo, i-valve yangaphambili, njl.
Emva kweemvavanyo ezahlukeneyo, xa iimeko zokusebenza zihlangabezana neemeko zokulawula, i-vacuum furnace ingasebenzisa inkqubo yokulawula ngokuzenzekelayo ukusebenza, enokuqinisekisa ukuba inokugqiba kakuhle umsebenzi.
Emva kokuba isithando somlilo silungiswe, kufuneka sihlolwe rhoqo kwinqanaba lokuqala lokusetyenziswa ukujonga ukuba izinga lokushisa elingaphezulu elisetyenzisiweyo lihambelana neqondo lokushisa langempela kwisithando somlilo (jonga rhoqo kwaye ulinganise i-vacuum gauge, umlawuli weqondo lokushisa, i-thermocouple, i-voltmeter kunye ne-ammeter).
Jonga i-heater yesigaba esithathu ngomonakalo ogqithisiweyo, ubushushu obungalinganiyo okanye ubumhlophe.
Kwimigangatho emithathu yobushushu obuphezulu kunye nezixhobo zokumelana ne-vacuum, xa umthamo udlula i-100kW, i-ammeter kufuneka ifakwe kwisigaba ngasinye kunye nendawo nganye yokufudumeza. Ukuba ubushushu besixhobo kunye nesalathiso sesixhobo asiqhelekanga, kufuneka sihlalutywe kwaye kusetyenzwe ngaso kwangethuba.
Ukuhlolwa emva kokugcinwa kwesithando somlilo ngumsebenzi obalulekileyo. Abasebenzisi kufuneka banikele ingqalelo xa beyisebenzisa, kwaye benze umsebenzi olungileyo kuhlolo olwahlukeneyo ngokungqinelana ngqongqo neemfuno ezifanelekileyo.
