Kev siv Recarburizer

1. Rauv input method:

Recarburizer yog tsim rau melting nyob rau hauv induction rauv, tab sis kev siv tshwj xeeb tsis zoo ib yam raws li cov txheej txheem yuav tsum tau ua.
(1) Kev siv cov recarburizer nyob rau hauv nruab nrab zaus hluav taws xob rauv melting tuaj yeem muab ntxiv rau hauv nruab nrab thiab qis ntawm lub cub hluav taws xob raws li qhov sib piv lossis cov pa roj carbon sib npaug, thiab tus nqi rov qab tuaj yeem ncav cuag ntau dua 95%;
(2) Molten hlau yog tias cov pa roj carbon ntau tsis txaus los kho lub sijhawm cov pa roj carbon monoxide, ua ntej ntxuav cov molten slag hauv lub cub tawg, thiab tom qab ntawd ntxiv cov recarburizer, los ntawm cov kua hlau cua sov, electromagnetic stirring los yog dag ntxias kom yaj cov pa roj carbon monoxide, tus nqi rov qab tuaj yeem yog li 90, yog tias cov txheej txheem carburizing qis, uas yog, tus nqi tsuas yog melts ib feem ntawm cov hlau molten kub tsawg, tag nrho cov carburizing tus neeg sawv cev yog ntxiv rau cov kua hlau ib zaug.Nyob rau tib lub sijhawm, nws raug nias rau hauv cov kua hlau nrog cov khoom siv kom nws tsis txhob nthuav tawm cov kua hlau.Lub carburization ntawm cov kua hlau hauv txoj kev no tuaj yeem ncav cuag ntau dua 1.0%.

2. Sab nraum lub cub tawg carburizing:

(1) Lub pob yog txau nrog graphite hmoov, graphite hmoov yog siv los ua recarburizer, thiab lub tshuab tshuab yog 40kg / t, uas yuav tsum tau nce cov ntsiab lus ntawm cov kua hlau los ntawm 2% mus rau 3%.Raws li cov pa roj carbon cov ntsiab lus ntawm cov kua hlau maj mam nce, kev siv cov pa roj carbon tsawg.Qhov kub ntawm cov kua hlau ua ntej carburization yog 1600 ℃, thiab qhov nruab nrab kub tom qab carburization yog 1299 ℃.Graphite hmoov carburization, feem ntau siv nitrogen raws li cov cab kuj, tab sis nyob rau hauv industrial tsim tej yam kev mob, compressed cua yog yooj yim dua, thiab cov pa oxygen nyob rau hauv compressed cua combustion los tsim CO, tshuaj lom neeg cov tshuaj tiv thaiv tshav kub tuaj yeem them rau ib feem ntawm qhov kub thiab txias, thiab CO txo. huab cua yog qhov zoo rau kev txhim kho cov nyhuv carburization.
(2) Kev siv cov recarburizer thaum hlau, tuaj yeem yog 100-300mesh graphite hmoov recarburizer rau hauv pob, lossis los ntawm cov hlau trough nrog cov ntws mus rau hauv, tom qab cov kua hlau yog tag nrho nplawm, kom deb li deb tau kom yaj cov pa nqus, carbon rov qab tus nqi li ntawm 50%.
