Cov txheej txheem ntawm melting cam khwb cia hlau nyob rau hauv lub cub tawg muaj rau XNUMX yam:

(1) Rauv hauv ob sab phlu preheating: lub burner yog ignited thiab lub qhov cub hauv ob sab phlu yog preheated rau 800 ~ 1000 ℃.

(2) Kev pub mis: Tom qab qhov cub hauv ob sab phlu yog preheated, lub qhov cub lub cev yog qaij, thiab tus nqi ntxiv rau lub cub tawg los ntawm hydraulic chute, thiab lub cub tawg yog leveled tom qab tus nqi.

(3) Charge preheating: Lub burner ignites dua kom pib cua sov nqi. Thaum lub sij hawm them nqi preheating, lub cub hluav taws xob lub cev rotates intermittentently thiab maj mam nyob rau hauv pem hauv ntej thiab rov qab cov lus qhia. Tus nqi maj mam softened thiab pib melted thaum lub sij hawm no.

(4) Overheating ntawm molten hlau: Tsis ntev tom qab qhov pib melting ntawm tus nqi, lub cub tawg nkag mus rau theem overheating ntawm molten hlau. Thaum lub sij hawm overheating ntawm molten hlau, lub burner yog rhuab nrog lub hwj chim siab, thiab lub cub tawg lub cev rotates sai nyob rau hauv ib qho kev taw qhia.

(5) Kev ntsuas hlau ua kua: Thaum qhov kub ntawm cov hlau molten ua tau raws li qhov yuav tsum tau ua rau tapping, siv lub thermocouple lossis infrared tus pas ntsuas kub ntsuas qhov ntsuas kub ntawm cov hlau molten, thiab siv daim duab peb sab los yog lub cub tawg pem hauv ntej thermal analyzer los ntsuas qhov muaj pes tsawg leeg ntawm cov hlau molten.

(6) Tapping thiab pouring: Yog hais tias qhov kub thiab muaj pes tsawg leeg ntawm molten hlau ua tau raws li qhov yuav tsum tau, qhib lub qhov kais dej rau tapping thiab pouring lub casting.
