1, kev cuam tshuam ntawm carburizing tus neeg saib xyuas particle loj

Kev siv ntawmcarburizing tus neeg sawv cevCov txheej txheem carburizing suav nrog cov txheej txheem dissolution diffusion thiab oxidation poob txheej txheem, carburizing tus neeg sawv cev ntawm qhov sib txawv particle loj, dissolution diffusion tus nqi thiab oxidation poob tus nqi sib txawv, thiab carburizing tus neeg saib xyuas tus nqi yog nyob ntawm tus neeg sawv cev carburizing dissolution rau diffusion txoj kev loj hlob tus nqi thiab oxidation technology poob xam ceev ntawm kev tswj hwm, feem ntau, carburizing tus neeg saib xyuas cov khoom me me, Dissolution cov tshuaj tiv thaiv ceev ceev, poob thiab ceev yog loj;Lub carburizer muaj qhov loj me me, qeeb qeeb qeeb thiab qhov poob me me nce tus nqi.

2, lub zog ntawm cov kua hlau nplawm rau ntawm qhov nqus ntawm carburizing tus neeg sawv cev

Kev ntxhov siab txhawb kev sib cais thiab nthuav tawm ntawm cov pa roj carbon monoxide kom tsis txhob hlawv cov hlau ntab ntawm cov kua dej.Ua ntej lubcarburizing tus neeg sawv cevtuaj yeem yaj tag, lub sijhawm nplawm yog ntev thiab qhov nqus tau siab.Stirring kuj tseem tuaj yeem ua rau lub sijhawm luv ntawm carburizing rwb thaiv tsev, txo lub voj voog ntau lawm, thiab zam kev sib tsoo ntawm cov ntsiab lus alloying hauv cov hlau kub.Txawm li cas los xij, lub sijhawm nplawm ntev dhau lawm, cov pa roj carbon yaj hauv cov kua nplawm hlau yuav ua rau cov pa roj carbon ntau ntau dua.Yog li ntawd, qhov tsim nyog sib tov lub sij hawm tswj cov kua hlau yuav tsum tau xyuas kom meej tias cov carburizer tuaj yeem yaj tag.

　　3, qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov nqus ntawm carburizer

Raws li kev txheeb xyuas los ntawm kev pom ntawm ib feem ntawm cov tshuab thiab cov thermodynamics, cov oxidation ntawm cov kua hlau muaj feem xyuam rau qhov sib npaug ntawm kev ua haujlwm kub hloov ntawm C-Si-O system, uas yog, O hauv cov kua hlau yuav muaj kev cuam tshuam tsis zoo nrog C thiab Si. .Qhov sib npaug kub hloov nrog cov ntsiab lus ntawm C thiab Si.Yog li ntawd, thaum qhov sib npaug ntawm kev ua haujlwm kub siab tshaj, qhov nqus ntawm carburant tuaj yeem txo.Thaum qhov kub ntawm carburizing qis dua qhov sib npaug ntawm qhov ntsuas kub, qhov saturated solubility ntawm carbon yog txo vim qhov kub thiab txias, thiab kev loj hlob tus nqi ntawm carbon dissolution thiab diffusion yog poob, yog li cov yield kuj tsawg;Carburizing kub ntawm qhov sib npaug tswj qhov kub, carburizing tus neeg saib xyuas tus nqi yog siab.

4, kev cuam tshuam ntawm kev sib ntxiv ntawm carburizing tus neeg sawv cev

Hauv qhov ntsuas kub thiab tshuaj lom neeg muaj pes tsawg leeg, qee cov kua roj carbon muaj qhov zoo ib yam ntawm cov hlau saturation concentration.Kev sib xyaw ntawm carbon hauv cam khwb cia hlau rau ([C] % = 1.30.0257 t - 0.31% [Si] 0.33 [P] % 0.45 [% S] 0.028 [Mn %] rau kub hlau kub (t). degree ntawm saturation, qhov ntau carburizer yog ntxiv, lub sij hawm ntev yuav tsum tau rau dissolution thiab diffusion, ntau dua qhov sib thooj poob, thiab tus nqi nqus yuav raug txo.

5, lub zog ntawm cov hlau liquefaction tshuaj muaj pes tsawg leeg ntawm qhov nqus ntawm carburizer

Thaum cov kua hlau yog siab nyob rau hauv thawj cov ntsiab lus carbon, qhov nqus ntawm cov yaj carburant qeeb, qhov nqus ntawm cov carburant tsawg dua, thiab qhov sib txuas loj loj yog tsawg.Thaum thawj cov ntsiab lus carbon ntawm cov kua hlau yog qhov tsawg, qhov xwm txheej yog thim rov qab.Tsis tas li ntawd, silicon thiab sulfur nyob rau hauv cov kua hlau thaiv kev nqus ntawm carbon thiab txo qhov nqus ntawm carbon enhancers.Manganese pab txhawb rau kev nqus cov pa roj carbon monoxide thiab ua kom cov pa roj carbon zoo dua.Nyob rau hauv cov nqe lus ntawm lub hwj chim degree, silicon yog qhov loj tshaj plaws, manganese yog qhov thib ob, carbon, sulfur yog tsawg.Yog li ntawd, hauv cov txheej txheem tsim khoom thiab kev tsim kho tiag tiag, manganese yuav tsum tau ntxiv ua ntej, tom qab ntawd carbon, thiab tom qab ntawd silicon.
