Indlela yokusetyenziswa kunye nokugcinwa kwe ukuchithwa kwesithando somlilo

1. I-furnace body tilting: Kufuneka iqondwe ngesiphatho kwi-console. Gcoba isibambo sokusebenza se-valve yokubuyisela umva ngeendlela ezininzi ukuya kwindawo “phezulu”, kwaye isithando somlilo siya kuphakama, sibangele ukuba isinyithi se-liquid siphalaze kwi-nozzle yesithando somlilo. Ukuba isibambo sibuyiselwe kwindawo ephakathi “ye-stop”, isithando somlilo siya kuhlala kwindawo yokuqala, ngoko umzimba wesithando somlilo unokuhlala kuyo nayiphi na indawo phakathi kwe-0-95 °. Gcoba isibambo kwindawo “ezantsi”, kwaye umzimba wesithando somlilo unokuthotywa kancinci.

2. Isixhobo se-furnace ejector ye-furnace: Nciphisa umzimba wesithando somlilo kwi-90 °, qhagamshela i-cylinder ye-ejector kunye nenxalenye ephantsi yesithando somlilo, udibanise i-hose ephezulu yoxinzelelo kwaye ulungelelanise isivinini se-ejector cylinder. Tyhila isibambo “somlilo wesithando” kwi-console ukuya kwindawo “ekuyo” ukukhupha i-lining endala. Tsala isibambo kwindawo “emva”, yisuse emva kokuba i-cylinder ihoxisiwe, phinda usethe umzimba wesithando somlilo emva kokucoca isithando somlilo, khangela i-refractory mortar kwaye uphakamise imodyuli ye-ejector ukuze uqale ukudibanisa i-lining entsha yesithando somlilo.

3. Xa isithando sokunyibilikisa i-induction sisebenza, kufuneka kubekho amanzi aneleyo okupholisa kwi-inductor. Ngalo lonke ixesha ujonge ukuba ubushushu bamanzi kumbhobho ngamnye wokuphuma buqhelekile.

4. Umbhobho wamanzi okupholisa kufuneka uhlanjululwe ngomoya oxinyiweyo rhoqo, kwaye umbhobho womoya oxinyiweyo unokudibaniswa nomdibaniso kumbhobho wokungena kwamanzi. Cima umthombo wamanzi phambi kokuba uqhawule umdibaniso wombhobho.

5. Xa isithando somlilo sivaliwe ebusika, kufuneka kuqatshelwe ukuba akukho manzi aseleyo kwi-coil induction coil, kwaye kufuneka ivuthwe ngomoya ocinezelweyo ukukhusela umonakalo kwi-inductor.

6. Xa ufaka i-busbar ye-furnace yokuncibilika kwe-induction, i-bolts yokudibanisa kufuneka iqiniswe, kwaye emva kokuba isithando sivuliwe, iibhotshi kufuneka zihlolwe rhoqo ukuze zikhululeke.

7. Emva kokuba i-furnace yokuncibilika kwe-induction ivuliwe, khangela ukuba i-bolts yokudibanisa kunye ne-fastening bolts ikhululekile, kwaye uhlawule ingqalelo ngakumbi kwiibholiti ezidibanisa iiplati zokuqhuba.

8. Ukuze kuthintelwe iingozi ezibangelwa ukuvuza kwezantsi kwesithando somlilo, isixhobo sokuvuza kwesithando somlilo sifakwe phantsi kwesithando somlilo. Nje ukuba isinyithi esilulwelo sivuze, siya kudityaniswa ne-electrode yensimbi engenastainless kwintsini yesithando somlilo kwaye isixhobo se-alam siyakuvulwa.

9. Xa udonga lwe-crucible ludliwe, kufuneka lulungiswe. Ukulungiswa kwahlula ngamatyala amabini: ukulungiswa ngokupheleleyo kunye nokulungiswa kwenxalenye.

9.1. Ulungiso olubanzi lweziko lokunyibilikisa induction:

Isetyenziswe xa udonga lwe-crucible lukhukuliswe ngokufanayo ukuya kubukhulu obumalunga ne-70mm.

Amanyathelo okulungisa ami ngolu hlobo lulandelayo;

9.2. Gcoba yonke i-slag eqhotyoshelwe kwi-crucible de kube i-white layer eqinile iphuma ngaphandle.

9.3. Beka i-mold crucible efanayo njengoko isetyenziswe xa kwakhiwa isithando somlilo, iphakathi kwaye uyilungise kumda ophezulu.

9.4. Lungisa isanti yequartz ngokwefomula kunye nendlela yokusebenza enikezwe kwi-5.3, 5.4, kunye ne-5.5.

9.5. Thela isanti ye-quartz elungiselelwe phakathi kwe-crucible kunye ne-crucible mold, kwaye usebenzise i-φ6 okanye i-φ8 imivalo ejikelezayo yokwakha.

9.6. Emva kokudibanisa, yongeza intlawulo kwi-crucible kwaye uyifudumeze ukuya kwi-1000 ° C. Kungcono ukuyigcina iiyure ezi-3 phambi kokuba uqhubeke unyusa ubushushu ukuze unyibilike umrhumo.

9.7, ulungiso olungaphelelanga:

Isetyenziswe xa ubukhulu bodonga lwendawo bungaphantsi kwe-70mm okanye kukho ukukhukuliseka kunye nokuqhekeka ngaphezu kwekhoyili ye-induction.

Amanyathelo okulungisa ami ngolu hlobo lulandelayo:

9.8. Khupha i-slag kunye ne-sediment kwindawo eyonakeleyo.

9.10, Lungisa umrhumo ngepleyiti yensimbi, gcwalisa isanti elungiselelwe i-quartz, kunye ne-tamping. Lumka ungavumeli ipleyiti yentsimbi ihambe xa iramza.

Ukuba i-corrosion and cracking part ingaphakathi kwe-coil induction, kusafuneka indlela yokulungisa ebanzi.

9.11, Thambisa iindawo zokuthambisa zesithando sokufakelwa rhoqo.

9.12. I-hydraulic system ithatha i-20-30cst (50℃) ioli ye-hydraulic, ekufuneka igcinwe icocekile kwaye itshintshwe rhoqo.

9.13. Ngethuba lenkqubo yokunyibilikisa, ingqalelo kufuneka ihlawulwe kwizibonakaliso zesixhobo kunye neerekhodi zesixhobo sokuvuza kwe-alamu.
