Txoj kev siv Carburizer hauv qhov cub thaum Casting

Cov cua sov uas siv cov recarburizers muaj xws li hluav taws xob furnaces, cupolas, hluav taws xob arc furnaces, intermediate zaus induction furnaces, thiab lwm yam, thiaj li hais tias tus nqi ntawm cov seem steel yuav ua tau zoo heev, thiab tus nqi ntawm npua hlau yuav txo tau los yog tsis siv npua hlau. .

 

Lub recarburizer yog qhov tseeb ntawm kev pab zoo rau kev tsim cov castings. Rau tag nrho cov cam khwb cia hlau (grey cam khwb cia hlau, ductile hlau, vermicular graphite hlau, grey cam khwb cia hlau, dawb cam khwb cia hlau, thiab lwm yam), lub graphite nyob rau hauv lub graphite recarburizer yuav siv tau raws li ib tug pro-eutectic Nuclei ntawm graphite thiab eutectic graphite. Txawv castings xav tau ntau hom recarburizers. Los ntawm qhov kev xav ntawm tus nqi, xaiv qhov tsim nyog recarburizer yog qhov kev pab zoo rau qhov zoo ntawm castings thiab cov txiaj ntsig kev lag luam. Tsis tas li ntawd, cov kev tshawb fawb tau pom tias nrog sib txawv proportions ntawm carbonaceous recarburizers thiab tsis muaj cov txheej txheem carburizing, nyob rau hauv cov xwm txheej ntawm tib cov tshuaj lom neeg kawg ntawm cov hlau molten, cov ntsiab lus nitrogen hauv carburized cam khwb cia hlau nce, thiab nitrogen tsim los ntawm nitrogen nce. Boronide, thiab lwm yam, tuaj yeem siv los ua cov substrate ntawm graphite crystalline core, tsim cov nucleation zoo thiab kev loj hlob rau graphite. Li no txhim kho qhov zoo ntawm castings.

 

Raws li ib txwm muaj, lub recarburizer tau muab tso rau hauv lub cub tawg ua ke nrog cov seem hlau thiab lwm yam nqi. Qhov sib ntxiv ntawm cov tshuaj me me tuaj yeem muab ntxiv rau ntawm qhov chaw ntawm cov hlau molten, los yog nws tuaj yeem muab ntxiv rau hauv batch. (Ceeb Toom: Tsis txhob noj cov hlau molten ntau ntau los tiv thaiv oxidation ntau dhau, ua rau cov nyhuv carburization tsis tseem ceeb thiab kev puas tsuaj loj rau cov castings.)

 

Thaum siv recarburizers nyob rau hauv casting, nws yuav tsum tau muab sau tseg hais tias tus nqi ntawm recarburizer ntxiv yog xaiv raws li qhov loj ntawm txawv furnaces thiab kub ntawm lub cub tawg. Rau ntau hom cam khwb cia hlau, ntau hom recarburizers yuav tsum raug xaiv raws li kev xav tau. Cov ntsiab lus ntawm recarburizer nyob rau hauv kev ua lag luam yog ntau faib los ntawm 75-98.5. Nrog rau kev ua lag luam xav tau rau cov khoom lag luam zoo, kev lag luam recarburizer kuj hloov pauv, tshwj xeeb tshaj yog kev xaiv ntawm graphitized recarburizers tau ua ib kauj ruam tseem ceeb rau pem hauv ntej. Yog li ntawd, casting xaiv ntawm recarburizers kuj yog ib qho kev paub zoo heev.
