Umgomo wokulinganisa wokushisa kwe- i-billet induction heat furnace

Isilinganiso sokushisa seBillet: Ngesikhathi senqubo yokushisa, izinga lokushisa kwaphezulu lebhallet likalwa ngomgodi wekhoyili ohlangothini. Ikhanda lokulinganisa lokushisa elibonakalayo libheke ebusweni be-billet ngale mbobo. Ukulinganiswa kokushisa kwe-optical kuncike ebusweni be-billet kanye nasekusebenzeni kwayo. Kwinto ngayinye edinga ukufudunyezwa, i-potentiometer exhunywe ekhanda lokulinganisa ilungiswa ngokuhlolwa okuningi nezilinganiso zokuqhathanisa. Inhloso ukuthola ukuphambuka phakathi kwezinga lokushisa langempela nenani lesilinganiso esibonisiwe. Ngoba isilinganiso sokushisa kwe-optical sincike ebusweni be-billet, futhi isikhathi eside lapho i-billet ihlala ekushiseni okuphezulu izokhiqiza isikali se-oxide ebusweni, esizokwakha amagwebu ngemuva kwesikhathi eside futhi ekugcineni siwe. Izinga lokushisa lale ungqimba lwamabhamuza liphansi kunezinga le-billet, okudala amaphutha ekushiseni okulinganisiwe.

Ngalesi sizathu, kushaywa i-nitrogen emigodini ekhoyili ukuvikela umoya-mpilo osemoyeni ozungezile ekuthinteni ubuso betshe eliseduze kwephuzu lokulinganisa. Ukusetshenziswa kwe-nitrogen kumayelana ne-20L / h ye-billet enikezwe yi “slab induction heating furnace”. Ubuso be-billet buya ngasemshinini wokushaya futhi ngenkathi kwenziwa isibhakela, bese kuba inqubo yokukhipha kusuka kumshini wokushaya. Sizodalulwa kumkhathi ozungezile. Ngakho-ke, kukhiqizwe ungqimba lwesikali se-oxide ebusweni be-billet. Ukuze ususe isikali se-oxide, kufakwa umbhobho womoya ocindezelwe ngaphansi kwe- “steel billet induction heating furnace”. Lapho ishaja, umbhobho ushaya umoya ocindezelwe ebusweni be-billet ukuze ususe isikali se-oxide esivulekile endaweni yesilinganiso sokushisa se-billet bese uyicindezela. Imfuneko yomoya icishe ibe yi-45m3 / h, ikhanda lokulinganisa lokushisa lokushisa, izinga lokushisa elilinganisiwe liqoshwa irekhoda lokushisa. Lapho ukushisa kokushisa kudlula ukushisa okuphezulu okucacisiwe, ukunikezwa kwamandla kwe-inductor kuyanqanyulwa ukuqinisekisa ukuthi i-billet ayishisi ngokweqile; lapho izinga lokushisa kwe-billet liphansi kunaleyo echaziwe, ukunikezwa kwe-inductor kuvulwa ngokuzenzakalela. Ukusebenza kwesithando somlilo “sokushisa”: Kumabhilidi wensimbi kazibuthe athambekele ekuqhekekeni, lapho kufudunyezwa ezingeni lokushisa elingaphansi kwephuzu laseCurie, isivinini sokushisa siyashesha kakhulu. Ukuze uvikele imifantu ku-billet, kungasetshenziswa amandla aphansi kuphela ekusebenzeni. Lapho ukushisa kokushisa kudlula ukushisa kwephoyinti le-Curie, amandla we-inductor ayancipha, futhi ijubane lokushisa le-billet lihamba kancane kakhulu. Amandla we-inductor kufanele akhuliswe ukushisa i-billet ekushiseni okudingekayo kwe-extrusion ngamandla aphezulu.
