Kev tsis xws luag thiab kev tiv thaiv ntawm carburization nyob rau hauv tubular furnaces

Cov pa roj carbon deficiency hauv cheeb tsam tom qab carburization:
Ua rau thiab muaj kev phom sij: Thaum lub sij hawm cov khoom carburization, cov khoom siv hluav taws xob ntau dhau los yog cov khoom tsis huv xws li pob zeb, kev sib xyaw tsis sib xws ntawm cov neeg ua haujlwm carburizing thiab charcoal, los yog kev sib cuag nrog cov khoom ua haujlwm tuaj yeem ua rau cov pa roj carbon deficiency hauv zos lossis carbon deficiency. Cov av ntawm qhov chaw ntawm lub workpiece tuaj yeem ua rau cov pa roj carbon deficiency.
Txoj kev tiv thaiv:
Lub workpiece loaded rau hauv lub cub tawg yuav tsum tsis txhob kov. Thaum cov khoom siv carburizing, tus neeg sawv cev carburizing yuav tsum tau compacted los tiv thaiv cov carburizing los ntawm collapsing thiab ua rau cov workpiece los rau hauv kev sib cuag.
Khoom carburizing tus neeg sawv cev yuav tsum tau npaj nyob rau hauv kev faib ua feem thiab stirred tusyees.
Tab sis tshem tawm cov av ntawm qhov chaw.
Carbon concentration siab dhau:
Ua rau thiab muaj kev phom sij: Yog tias cov txheej txheem carburizing yog cua sov sai, qhov kub thiab txias yog siab dhau, los yog siv cov carburizing tus neeg sawv cev tshiab thaum lub sij hawm cov khoom carburizing, los yog siv cov carburizing muaj zog ntau dhau, nws tuaj yeem ua rau muaj qhov tshwm sim ntawm cov carburizing siab concentration. Raws li cov pa roj carbon ntau dhau lawm, blocky thiab coarse carbides los yog network carbides tshwm nyob rau saum npoo ntawm workpiece. Vim qhov tsim ntawm no nyuaj thiab nkig qauv, lub toughness ntawm carburized txheej sharply txo. Tsis tas li ntawd, high carbon martensite yog tsim thaum lub sij hawm quenching, thiab sib tsoo cov kab nrib pleb yog yooj yim tshwm sim thaum sib tsoo.
Txoj kev tiv thaiv:
Nws tsis pom zoo kom ua kom sov sai sai, tab sis siv cov cua sov kom tsim nyog los tiv thaiv kev loj hlob ntawm cov hlau. Yog hais tias cov nplej yog ntxhib thaum lub sij hawm carburization, lawv yuav tsum tau kho kom zoo los ntawm normalizing los yog ob quenching kev kho mob tom qab carburization.
Lub cub tawg kub uniformity yuav tsum tau tswj nruj me ntsis thiab yuav tsum tsis txhob hloov ntau dhau. Tshwj xeeb yuav tsum tau them rau cov khoom carburization nyob rau hauv reverberatory rauv.
Thaum cov khoom carburizing, tus neeg sawv cev carburizing yuav tsum tau siv nyob rau hauv ib qho tshiab thiab qub piv. Nws yog qhov zoo tshaj plaws los siv 4-7 feem pua ​​BaCO3 ua tus neeg nkag mus, thiab Na2CO3 tsis siv los ua tus neeg nkag mus.
Tsawg carbon concentration:
Ua rau thiab muaj kev phom sij: Cov kub hloov pauv loj lossis cov tshuaj nkag tsis txaus tuaj yeem ua rau cov pa roj carbon concentration tsis txaus. Qhov zoo tshaj plaws carbon concentration rau tubular rauv yog nyob nruab nrab ntawm {{0}}}9-1.0 feem pua ​​, qis dua 0.8 feem pua ​​C, thiab cov khoom yog nquag hnav thiab tsim kua muag.
Txoj kev tiv thaiv:
Txoj kev tiv thaiv: Cov tshiab thiab qub carburizing tus neeg sawv cev yuav tsum tau npaj raws li qhov kev qhia piv, thiaj li yooj yim rau cov txheej txheem carburizing. Nws yog qhov zoo dua los siv BaCO3 ua tus neeg sawv cev carburizing vim Na2CO3 sai dua.
Qhov kub ntawm carburizing feem ntau yog 920-940 degree . Yog tias qhov kub ntawm carburizing tsawg dhau, nws yuav ua rau cov pa roj carbon concentration tsawg dhau thiab ua rau lub sijhawm carburizing ntev; Qhov kub ntawm carburization ntau dhau tuaj yeem ua rau cov nplej coarsening.
Qhov ntau npaum ntawm tus neeg sawv cev nkag mus (BaCO3) yuav tsum tsis pub tsawg dua 4 feem pua.

Tempering thiab tawg thaum sib tsoo:
Yog vim li cas rau qhov tshwm sim: Qhov tshwm sim ntawm softening nyob rau saum npoo ntawm carburized txheej tom qab sib tsoo yog hu ua tempering los ntawm kev sib tsoo. Qhov no yog vim hais tias tus nqi noj thaum lub sij hawm sib tsoo yog ceev heev, lub hardness thiab particle loj los yog ceev ntawm lub sib tsoo log yog xaiv tsis raug, thiab tsis txaus cua txias thaum lub sij hawm sib tsoo txheej txheem yuav ua rau xws li tsis xws luag. Qhov no yog vim lub tshav kub generated thaum sib tsoo softens saum npoo. Thaum tempering tsis xws luag tshwm sim thaum sib tsoo, hnav tsis kam ntawm ib feem txo.
Hexagonal tawg tshwm nyob rau saum npoo. Feem ntau yog vim muaj kev sib tsoo ntau dhau ntawm qhov sib tsoo nyuaj, ua rau muaj kev kub ntxhov. Nws kuj muaj feem xyuam rau qhov tsis txaus tempering thaum lub sij hawm kho cua sov thiab cov seem seem sab hauv. Tom qab cov kua qaub etching, txhua qhov tsis xws luag tshwm sim dub thiab tuaj yeem paub qhov txawv ntawm cov tsis muaj qhov tsis xws luag. Qhov no yog tempering los ntawm tshav kub generated thaum sib tsoo. Yog vim li cas rau kev hloov ntawm nees lub cev rau hauv cov ntaub so ntswg troostite. Kev tawg tuaj yeem pom ntawm qhov muag liab qab tom qab sib tsoo.
Txoj kev tiv thaiv:
Siv ib lub mos lossis nruab nrab alumina sib tsoo log nrog qhov loj me ntawm 40-60, qhov sib tsoo pub tus nqi yuav tsum tsis txhob siab dhau.
Tom qab quenching, nws yog ib qho tsim nyog yuav tsum tau ua kom txaus tempering los yog ntau tempering kom tshem tawm cov kev ntxhov siab sab hauv.
Thaum sib tsoo, ua ntej tig rau lub coolant thiab xyuam xim rau kom txaus txias thaum lub sij hawm sib tsoo txheej txheem.
