Sib tsuam pom thiab kev ua haujlwm ntawm kev sib tsoo cov khoom sib forged

Forging sib tsoo pob mus rau ib qho twg, nrog nws cov kev ntsuam xyuas qhov tsim nyog nkhaus residual yuav tsum yog ib lub tsev qiv ntawv nrog ib tug ntau dua poob rau hauv txoj kab nqes ntawm lub inlet kawg, tag nrho cov khoom ntawm kawg ntawm lub warehouse yuav ze rau zeb tawm 0.5 ~ 0.8, nyob rau hauv ib cov degree degree Yuav muaj lub caij poob qis, yog tias lub khw muag khoom poob tsis pom tseeb, qhia tias tsis muaj peev xwm ua kom tau smashing; Yog hais tias qhov kawg ntawm ib sab ntev kab, qhov yuav tsum tau muab tshem tawm ntawm lub me me sib tsoo. Xyuas cov nqi seem ntawm qhov screen ua ntej thiab tom qab pawg neeg muab kev koom tes. Yog tias qhov sib txawv loj loj, nws txhais tau hais tias ob txoj haujlwm tsis txaus. Hloov qhov ntev ntawm txoj hauj lwm los yog kho lub pob ntawm lub cev sib tsoo kom sib npaug ntawm lub peev xwm ntawm ob txoj haujlwm.

Lub forged sib tsoo pob yuav nres kev sib tsoo raws li txoj kev pub muag. Yog hais tias feem ntau ntawm cov npas hlau hauv ib lub pob zeb yuav nthuav tawm ib nrab ntawm cov khoom siv deg, nws tsim nyog dua yog tias cov khoom kawg ntawm lub forging yog cia li dhau ntawm tus kheej. Yog tias ib qhov chaw ntu tshaj qhov chaw, nws txhais tau hais tias pob lub pob muaj zog tsawg los yog qhov khoom tsis txaus. Txwv tsis pub, lub pob ntawm lub pob yog loj heev thiab lub nra yog ntau dhau lawm. Yog hais tias muaj ntau cov khoom nyob rau hauv cov khoom siv nyob rau hauv qhov chaw kawg, nws txhais tau hais tias lub load yog tsis txaus, txwv tsis pub nws txhais tau hais tias lub load ntau dhau lawm. Yog hais tias txhua tus txheej txheem tho yog tuab heev thiab cov qoob loo yog qhov tsawg thiab qhov khoob tsis zoo txaus los tswj, xyuas seb qhov kev faib khoom faib thiab tawm ntawm lub rooj saib xyuas tawm sab nrauv los ntawm ntau cov khoom ya hauv qhov khoom thiab ua rau tshwm sim ntawm muab tshuaj txhuam thiab jam.

Lub forged sib tsoo pob yuav zoo qhov kev sib tsoo, khoom rov qab, thiab fineness ntawm cov khoom tiav rau ib qho twg, suav cov kev tsis sib tsoo thiab cais cov hmoov, thiab sojntsuam thiab txiavtxim qhov kev ua haujlwm ntawm cov haujlwm ntawm zeb haujlwm. Yog qhov tseem qhov tseem ceeb ntawm tag nrho peb yog siab dua tus nqi qub, nws yog ib qho tsim nyog ntxiv rau qhov tsim nyog rau nruab nrab los yog me me sib tsoo lub cev los yog nyeem ntawv t lawv.

Qhov zoo ntawm forged sib tsoo npas yog maj highlighted thiab dav siv. Cov npav loj loj yuav ua rau kev siv cov pob zeb diameter loj sib tsoo. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau npaj siab rau kev kawm siab thiab kev sib tw loj sib npaug. Daim ntawv no aims ntawm qhov teeb meem tawg ntawm 65Mn forging cov khoom nyob rau hauv tus txheej txheem ntawm manufacturing 65Mn forging npas nyob rau hauv ib lub koom haum, thiab tham txog qhov ua rau ntawm cov kab nrib rau 65Mn forged cov khoom siv metallographic kev soj ntsuam, SEM microscopic morphology kev soj ntsuam, EDS zog spectrum analysis, Rockwell hardness kev sim, thiab qhov kev sib tw muaj nqes. Ib qho tswv yim optimization tau npaj siab npaj 65Mn loj-hau forging cov khoom nrog cov khoom siv dag zog zoo.

Kev ntaus sib tsoo pob yuav ua rau nws txoj kev nyuab siab rau ib qho twg uas qee yam, txog qee yam, nws yuav tshaj qhov teeb meem ntawm qhov khoom tawg. Hauv kev khiav dej num, txoj kev npaj ua kom zoo tshaj plaws yog: Cov qib siab zoo thawj (Φ90mm) - Txiav rods luv - rhuab mus rau 1050 ° C - forging - hloov (900-920 ° C) - 800-820 ° C quenching, quenching fluid concentration of 2.5% - tempering (220 ° C-4 h). Tom qab qhov kev tsim kho ntawm txoj haujlwm, tsis muaj txheej txheem dej ntawm 65Mn poob lawm pom Wei qhov microstructure, qhov kev hloov pauv ntawm kev sib zog yog qhov ruaj khov, qhov nyuaj hardness ntau zog los ntawm 3HRC, thiab qhov tob ntawm hardened txheej ntxiv ntawm 2 hli.

Kauv phaj condenser yog tsuas yog siv nyob rau hauv nws cov qauv tshiab. Nws yog qhov yooj yim heev rau kev khiav lag luam. Nws yog ib qho tsim nyog rau txoj kev tsim. Qhov chaw sib txauv hauv tshav kub tuaj yeem siab tau los ntawm thawj 260m2 rau 800-100 m 2. Kev ua hauj lwm zoo yog qhov tseem ceeb. 3-4 zaug, thiab siv tau cov tshuab uas twb muaj lawm, dov khoom tsim. Nws muaj qhov zoo ntawm txoj kev khiav tawm yooj yim, txawm tias faib cov pa taws thiab tsis yaug roj, tsis tshua muaj roj qhov sib txawv, thiab qhov ntxim saib ntxim ua tseem ceeb.
