Ntxiv rau cov ntsiab lus ruaj khov thiab cov hmoov tshauv ntawm lub carburizer muaj qhov cuam tshuam tseem ceeb ntawm nws cov carburizing efficiency hauv cam khwb cia hlau, particle loj ntawm carburizer, txoj kev ntxiv, qhov kub ntawm cov kua hlau thiab cov nyhuv stirring nyob rau hauv lub cub tawg thiab. Lwm yam txheej txheem muaj txiaj ntsig zoo rau kev ua haujlwm ntawm carburizing.
Nyob rau hauv cov xwm txheej ntau lawm, ntau yam feem ntau ua lub luag haujlwm tib lub sijhawm, nws yog ib qho nyuaj rau kev piav qhia meej ntawm qhov cuam tshuam ntawm txhua yam, qhov yuav tsum tau ua kom zoo dua cov txheej txheem los ntawm kev sim.
1. Ntxiv txoj kev
Carburizing tus neeg saib xyuas hauv kev them nyiaj nrog cov nqi hlau ua ke rau hauv lub qhov cub, vim lub sijhawm ua haujlwm ntev, carburizing efficiency ntau dua li cov hlau thaum ntxiv cov kua hlau.
2. Qhov kub ntawm cov kua hlau
Thaum cov hlau recarburizer yuav muab ntxiv rau hauv lub hnab, thiab tom qab ntawd mus rau hauv cov kua hlau, carbon efficiency thiab kub ntawm cov kua hlau.Raws li kev tsim khoom ib txwm muaj, thaum qhov kub ntawm cov kua hlau yog siab dua, cov pa roj carbon ntau dua soluble hauv cov kua hlau thiab cov kev ua haujlwm ntawm carburization yog siab dua.
3 carburizer particle loj
Feem ntau, carburant hais me me, nws qhov kev sib cuag nrog cov hlau ua kua hauv cheeb tsam yog qhov loj, ua kom cov pa roj carbon ntau dua, tab sis cov khoom zoo heev ntawm oxidation yooj yim los ntawm oxygen los ntawm cov cua, kuj yooj yim los ntawm convection ntawm. huab cua los yog pa luam yeeb plua plav ntws tawm, yog li ntawd, carburant particle loj ntawm qhov qis qis tus nqi nrog 1.5 hli tau pom zoo, thiab yuav tsum tsis txhob muaj cov hmoov zoo hauv qab 0.15 hli.
Qhov loj me me yuav tsum tau ntsuas raws li tus nqi ntawm cov hlau molten uas tuaj yeem yaj thaum lub sijhawm ua haujlwm.Yog tias lub carburizer tau ntxiv ua ke nrog cov hlau them thaum thauj khoom, lub sijhawm ua haujlwm ntawm cov pa roj carbon monoxide thiab cov hlau yog ntev, qhov loj me ntawm carburizer tuaj yeem loj dua, thiab qhov txwv sab saud tuaj yeem yog 12 hli.Yog tias cov hlau ntxiv rau cov kua hlau, qhov loj me me yuav tsum me dua, qhov txwv sab saud feem ntau yog 6.5 hli.
4. do
Stirring yog qhov zoo los txhim kho kev sib cuag ntawm carburizer thiab kua hlau thiab txhim kho nws cov carburization efficiency.Nyob rau hauv cov ntaub ntawv ntawm carburizing tus neeg saib xyuas thiab them ua ke rau hauv lub qhov cub, muaj ib tug induced tam sim no stirring nyhuv, carburizing nyhuv yog zoo dua.Ntxiv tus neeg saib xyuas carburizing rau hauv lub hnab, tus neeg saib xyuas carburizing tuaj yeem muab tso rau hauv qab ntawm lub hnab, hlau thaum cov kua hlau ncaj qha blunt carburizing tus neeg saib xyuas, lossis tus neeg sawv cev carburizing txuas mus rau hauv cov kua ntws, tsis yog nyob rau hauv cov kua nto ntawm lub hnab tom qab hlau.
5 tsis txhob carburizing tus neeg sawv cev koom nrog hauv slag
Carburizing tus neeg sawv cev yog koom nrog hauv slag, tsis tuaj yeem tiv tauj nrog cov kua hlau, ntawm chav kawm, yuav cuam tshuam rau cov nyhuv ntawm carburizing.
