Indlela yokukhangela i-lining of induction melting furnace

1. Ukhukuliseko emazantsi eziko

Ekusetyenzisweni okuqhelekileyo kwesithando somlilo, ubukhulu bomgca wesithando somlilo kunye nobukhulu bezantsi kwesithando somlilo buya kuba buncinci ngenxa yokukhukuliseka kwe-cyclic yensimbi etyhidiweyo ngexesha lokusetyenziswa kwexesha elide. Imeko enembileyo kukunyuka komthamo wesithando somlilo, kwaye i-furnace lining ngokubanzi iya kutshatyalaliswa ngu-30-50%. Xa kufika ixesha, iya kudilizwa kwakhona, kuze kwenziwe umsebenzi omtsha wokwakha iziko.

Ukususela kuhlalutyo lwalo lonke uphahla lwesithando somlilo, ukuguguleka okucacileyo kukwindawo yethambeka apho i-furnace bottom kunye ne-furnace lining idibene. Emva kokusetyenziswa kwexesha elide lesithando somlilo, i-furnace lining material kwi-slope iye yachithwa ukuze ifane ne-furnace lining. Isithando somlilo sisetyhula kwi-arc surface, kwaye kwanokudandatheka okuncinci kubonakala kumhlaba apho izinto eziphantsi kwesithando somlilo kunye nezixhobo zokugubungela isithando somlilo zidibene. Njengoko ixesha lesithando somlilo likhula, ukudakumba kwesi sikhundla kuya kuba nzulu kwaye kunzulu, ukusondela kwaye usondele kwikhoyili yesithando sombane , Kwaye kuchaphazela ukusetyenziswa kokhuseleko, kufuneka uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uqhube isithando somlilo. Ukongeza kobuninzi besanti ye-quartz ngexesha lokwakhiwa kwesithando somlilo, imbangela yokudakumba kwe-lining nayo ihambelana nokubola kweekhemikhali ngexesha lokunyibilika kwezinto ekusetyenzisweni kwethu kunye nokutshatyalaliswa komatshini ngexesha lokusebenza.

2. Ingqibelelo yesithando somlilo

Ukunyaniseka kwe-lining kubhekisela ekungeneni kwentsimbi kunye nokuqhekeka okuhlala kubonakala kwi-lining. Kwimveliso yethu, kuhlala kukho ikhefu leempelaveki kunye neziko. Xa isithando sombane sichithwa kwaye siyeka ukunyibilika, i-furnace lining iya kuphola kancinci kancinci. Ngenxa yokuba i-sintered furnace lining iyimpahla enqabileyo, i-sintered layer ayinakuphepheka ngenxa yokwandiswa kwe-thermal kunye nokucutha. Ukuqhekeka kubonakala, okuyingozi kakhulu kwaye kuya kubangela ukuba isinyithi esinyibilikisiweyo singene kwi-lining yesithando somlilo kwaye sibangele ukuvuza kwesithando somlilo.

Ukusuka kwimbono yokukhusela i-lining, iintanda zincinci kwaye zixinene kwaye zisasazwe ngokulinganayo, kuba ngale ndlela kuphela iintanda ezinokuvalwa kumda xa isithando somlilo siqala ukubanda, kwaye i-sintering layer inganikezelwa. umgca. Ukuze kuncitshiswe ukwanda kokuqhekeka, kufuneka sithathele ingqalelo: kuphephe ukuncamathelisa i-slag, impembelelo yobushushu obuphezulu obugqithileyo kwilayini yesithando somlilo, ukupholisa umbane wesithando somlilo, kunye nokuhlolwa rhoqo komphezulu wesithando somlilo.
