Sebenzisa iziko lokunyibilikisa ngokukhuselekileyo kwaye ujonge imikhwa elungileyo esi-7!

(1) Frequently observe the melting situation in the furnace. The charge should be added in time before the charge is completely melted. It is found that the scaffolding should be treated in time to avoid the furnace wearing out due to the sharp rise of the molten iron temperature under the shed, which exceeds the melting point of the charge (quartz sand 1704℃). To

2 Ukuya

(3) Kwiimeko eziqhelekileyo, xa udonga lwe-crucible luyi-1/3 ye-original lining ye-furnace, isithando somlilo kufuneka sichithwe kwaye sakhiwe kwakhona. Ukuya

(4) Intsimbi etyhidiweyo ifanele ithululwe kanye ngeveki ukuze kulinganiswe ubungakanani becala leziko kunye nokujonga ubume balo bomphezulu, ukuqonda eyona meko yokwakheka kweziko kwangethuba, nokusingatha naziphi na iingxaki ngexesha. Ukuya

(5) I-recarburizer ingcono yongezwa kancinci kancinci ngexesha lenkqubo yokongeza intlawulo yesinyithi. Ukongeza kwangoko kakhulu kuya kubambelela ezantsi kwesithando somlilo kwaye akuyi kunyibilika ngokulula kwintsimbi etyhidiweyo. Ukongeza emva kwexesha kakhulu kuya kwandisa ixesha lokunyibilika kunye nokufudumeza, okungayi kubangela ukulibaziseka kokulungelelaniswa kokwakheka, kodwa kunokubangela ubushushu obuphezulu. Ukongezwa kwe-ferrosilicon (ukwandisa i-Si), kwi-induction yokunyibilika kwiziko elinamandla anamandla ashukumisayo, kuba umxholo we-Si ophezulu kwintsimbi etyhidiweyo uya kubangela ukunyuka okungahambi kakuhle kwe-C, kungcono ukongeza i-Si iron kamva, kodwa iya kubangela intsimbi eziko. . Ukulibaziseka kuhlalutyo lokwakheka kolwelo kunye nohlengahlengiso. Ukuya

(6) Ukushiya isinyithi esilulwelo kwisithando somlilo ngexesha lokunyibilika kunokunceda ukuphucula ukusebenza kombane kwezinye iindawo zombane kunye nokuphucula amandla ombane wesigaba sokunyibilika. Nangona kunjalo, ezi ntsimbi zityhidiweyo zinokuthi zifudumeze kakhulu kwiziko ixesha elide kwaye zibeke emngciphekweni umgangatho wesinyithi. Ngoko ke, intsalela yesinyithi etyhidiweyo kufuneka iphendule kwi-15% yomthamo wesithando somlilo. Isinyithi esinyibilikisiweyo esincinci kakhulu siya kuyenza ibe mandundu imeko yobushushu, kwaye intsimbi eninzi etyhidiweyo iya kunciphisa ukusetyenziswa okusebenzayo kwentsimbi etyhidiweyo kwaye yandise ukusetyenziswa kwamandla eyunithi. Ukuya

(7) Ubungqingqwa bentlawulo bukhethwa ukuba yi-200～300mm. Okukhona ubukhulu becala, kokukhona ukunyibilika kucotha.
