Ntxiv rau cov pa roj carbon thiab cov tshauv uas ruaj khov ntawm lub carburizer muaj qhov cuam tshuam tseem ceeb rau nws qhov kev ua haujlwm carburizing hauv cov hlau cam khwb cia, qhov loj me ntawm cov carburizer, txoj kev ntxiv, qhov kub ntawm cov hlau ua kua thiab qhov cuam tshuam hauv lub cub tawg thiab lwm yam txheej txheem muaj qhov cuam tshuam tseem ceeb rau qhov ua haujlwm ntawm carburizing.
Hauv cov xwm txheej tsim khoom, ntau yam feem ntau ua lub luag haujlwm tib lub sijhawm, nws nyuaj rau piav qhia meej txog qhov cuam tshuam ntawm txhua yam, qhov xav tau los ua kom zoo dua cov txheej txheem los ntawm kev sim.
1. Ntxiv txoj kev
Tus neeg sawv cev carburizing thaum them nrog cov hlau them ua ke rau hauv lub cub tawg, vim yog lub sijhawm ntev ntawm kev ua haujlwm, carburizing efficiency yog siab dua li hlau thaum ntxiv cov hlau kua.
2. Kub ntawm cov hlau ua kua
Thaum cov hlau recarburizer yuav raug ntxiv rau hauv lub hnab, thiab tom qab ntawd rau hauv cov hlau ua kua, cov pa roj carbon ua haujlwm zoo thiab qhov kub ntawm cov hlau ua kua. Nyob rau hauv cov xwm txheej ib txwm muaj, thaum qhov kub ntawm cov hlau ua kua siab dua, cov pa roj carbon yaj ntau dua hauv cov hlau ua kua thiab qhov ua tau zoo ntawm carburization siab dua.
3 qhov loj me ntawm cov carburizer
Feem ntau, cov khoom me me ntawm carburant, nws qhov kev sib cuag nrog cov kua hlau interface cheeb tsam loj, ua kom cov pa roj carbon ua haujlwm zoo dua, tab sis cov khoom me me uas yooj yim oxidized los ntawm cov pa oxygen los ntawm huab cua, kuj yooj yim los ntawm kev sib xyaw ntawm huab cua lossis cov hmoov av pa luam yeeb ntws tawm, yog li ntawd, cov khoom me me ntawm carburant ntawm qhov qis tshaj plaws nrog 1.5 hli pom zoo, thiab yuav tsum tsis txhob muaj cov hmoov zoo hauv qab 0.15 hli.
Qhov loj ntawm cov khoom me me yuav tsum tau ntsuas raws li qhov ntau ntawm cov hlau uas yaj tau thaum lub sijhawm ua haujlwm. Yog tias lub carburizer ntxiv nrog cov hlau thaum thauj khoom, lub sijhawm ua haujlwm ntawm cov pa roj carbon thiab hlau ntev, qhov loj ntawm cov khoom me me ntawm lub carburizer tuaj yeem loj dua, thiab qhov txwv siab tshaj plaws tuaj yeem yog 12 hli. Yog tias cov hlau ntxiv rau cov hlau ua kua, qhov loj ntawm cov khoom me me yuav tsum me dua, qhov txwv siab tshaj plaws feem ntau yog 6.5 hli.
4. Do
Kev sib xyaw ua ke zoo heev rau kev txhim kho kev sib cuag ntawm cov carburizer thiab cov hlau ua kua thiab txhim kho nws cov kev ua haujlwm carburization. Yog tias tus neeg sawv cev carburizing thiab them ua ke rau hauv lub cub tawg, muaj qhov cuam tshuam tam sim no induced, qhov cuam tshuam carburizing zoo dua. Ntxiv tus neeg sawv cev carburizing rau hauv lub hnab, tus neeg sawv cev carburizing tuaj yeem muab tso rau hauv qab ntawm lub hnab, hlau thaum cov hlau ua kua ncaj qha blunt carburizing tus neeg sawv cev, lossis tus neeg sawv cev carburizing txuas ntxiv mus rau hauv cov kua ntws, tsis yog nyob rau hauv qhov chaw kua ntawm lub hnab tom qab hlau.
5 zam cov neeg sawv cev carburizing uas koom nrog hauv slag
Yog tias tus neeg sawv cev carburizing koom nrog slag, tsis tuaj yeem sib cuag nrog cov kua hlau, ntawm chav kawm, yuav cuam tshuam loj heev rau cov nyhuv ntawm carburizing.
