Cov cub tawg uas siv cov recarburizers suav nrog cov cub tawg hluav taws xob, cupolas, hluav taws xob arc furnaces, intermediate frequency induction furnaces, thiab lwm yam, yog li ntawd cov hlau seem tuaj yeem nce ntxiv ntau heev, thiab cov hlau npua tuaj yeem txo qis lossis tsis siv hlau npua.
Lub recarburizer yeej pab tau zoo heev rau kev tsim cov castings. Rau txhua yam cast iron (grey cast iron, ductile iron, vermicular graphite iron, grey cast iron, white cast iron, thiab lwm yam), graphite hauv graphite recarburizer siv tau ua pro-eutectic Nuclei ntawm graphite thiab eutectic graphite. Cov castings sib txawv xav tau ntau hom recarburizers. Los ntawm qhov pom ntawm tus nqi, kev xaiv lub recarburizer tsim nyog yog qhov pab tau zoo rau qhov zoo ntawm castings thiab cov txiaj ntsig kev lag luam. Tsis tas li ntawd, kev tshawb fawb tau qhia tias nrog cov feem sib txawv ntawm carbonaceous recarburizers thiab tsis muaj cov txheej txheem carburizing, nyob rau hauv qhov xwm txheej ntawm tib qho tshuaj lom neeg kawg ntawm cov hlau molten, cov ntsiab lus nitrogen hauv carburized cast iron nce, thiab nitrogen tsim los ntawm nitrogen nce. Boronide, thiab lwm yam, tuaj yeem siv ua lub substrate ntawm graphite crystalline core, tsim cov nucleation zoo thiab kev loj hlob rau graphite. Yog li txhim kho qhov zoo ntawm castings.
Nyob rau hauv qhov xwm txheej ib txwm muaj, lub recarburizer raug muab tso rau hauv lub cub tawg ua ke nrog cov hlau seem thiab lwm yam nqi. Kev ntxiv cov koob tshuaj me me tuaj yeem ntxiv rau ntawm qhov chaw ntawm cov hlau yaj, lossis nws tuaj yeem ntxiv ntau hauv cov khoom. (Ceeb Toom: Tsis txhob pub cov hlau yaj ntau ntau kom tiv thaiv kev oxidation ntau dhau, ua rau muaj kev cuam tshuam me me thiab kev puas tsuaj loj rau cov castings.)
Thaum siv cov recarburizers hauv kev casting, nws yuav tsum tau sau tseg tias qhov ntau ntawm cov recarburizer ntxiv yog xaiv raws li qhov loj ntawm cov cub tawg sib txawv thiab qhov kub ntawm lub cub tawg. Rau ntau hom hlau cam khwb cia, ntau hom recarburizers yuav tsum tau xaiv raws li qhov xav tau. Cov ntsiab lus ntawm recarburizer ntawm kev ua lag luam tau faib ntau dua los ntawm 75-98.5. Nrog rau kev ua lag luam xav tau rau cov khoom zoo, kev ua lag luam recarburizer kuj tseem hloov pauv, tshwj xeeb tshaj yog kev xaiv cov graphitized recarburizers tau ua ib kauj ruam tseem ceeb rau pem hauv ntej. Yog li ntawd, kev xaiv casting ntawm recarburizers kuj yog ib qho kev paub zoo heev.
