Dab tsi yog cov yam ntxwv thiab kev lag luam ntawm kev sib tsoo tawm cov hlau npog?

Kev sib tsoo tawm steel hlau, uas yog ib hom hlau pob, kuj yog ib qho thiab feem ntau siv hom hlau nyob rau hauv vim tias lawv tau siv qee cov lag luam thiab cov khoom. Ntxiv mus, los ntawm lwm lub tswv yim, nws yog ib qhov tsim nyog yuav tau muaj kev nkag siab thiab kev nkag siab txog qhov sib txawv ntawm lub pob hlau, yog li ntawd lub sib tsoo tawm cov hlau npas yuav raug siv nyob rau hauv ib qho teeb meem tsim.

Dab tsi yog kev sib tsoo tawm cov khoom hlau? Los ntawm ib qho kev pom kev, nws hais txog lub pob hlau los ntawm kev sib tsoo cov txheej txheem, thiab los ntawm qhov tam sim no pom, qhov sib txawv ntawm lub pob zeb no maj mam hloov lub pob casting siv. Thiab, nws muaj qee qhov kev zoo rau kev siv, yog:

Nws muaj qhov sib xyaw geometry, kev kub ntxhov thiab kev kho khoom zoo, thiab muaj kev coj zoo thiab tsis deform thiab tawg.

Qhov nws qhov chaw tawv nqaij muaj peev xwm ncav cuag 55-65HRC, qhov ntim ntawm qhov hnyav tuaj yeem ncav 50-62HRC, thiab nws cov gradient nyuaj yog sib npaug. Tsis tas li ntawd, hom kab hlau pob zeb no muaj kev cuam tshuam zoo heev thiab muaj peev xwm ncav cuag 12 J / cm 2 los yog ntau dua.

Nws muaj qhov tsis tshua tawg, thiab nws txoj kev ua kom tsis muaj zog yog ntau dua 10 npaug ntawm kev sib tsoo thiab cov hlau steel forged, thiab cov khoom yuav ua rau ntau tshaj 20,000 zaug. Tsis tas li ntawd, tus nqi txhawm nqi tsis tshaj 1%, thiab yeej tsis muaj kev tawg tau.

Raws li cov txiaj ntsim ntawm cov pob zeb kub kub kub, nws muaj peev xwm xaus tau tias cov pob zeb kub kub kub tau siv rau hauv cov kev siv thiab kev lag luam xws li kev txais txiaj ntsig, kev siv zog cog qoob loo, cov nroj tsuag cement thiab refractories, thiab siv tau zoo. nyhuv.

1. Yam ntxwv ntawm kev sib tsoo tawm cov khoom hlau

(1) Nws muaj cov khoom tsim tawm ntau hauv cov khoom thiab muaj peev xwm loj zuj zus. Tsis tas li ntawd, nws muaj peev xwm twb paub lawm tias tsis siv tshuaj lawm thiab txo nqi zog.

(2) Cov khoom zoo yog ruaj khov, qhov nyuaj yog qhov siab thiab qhov hardenability zoo, lub peev xwm ntawm cov metallographic yog compact thiab grain loj me, thiab cov deformation tsis yooj yim tshwm sim.

(3) Cov khoom tsim ua zoo, thaj av ua kam rau me me, thiab qhov zoo yog ruaj khov.

(4) Vim tias cov pob zeb no muaj qhov qis tsis tshua muaj nqes, cov khoom yuav ua tau rau lub neej ua haujlwm ntev.

2. Kev sib tsoo tawm xov xwm hlau khoom ntau txheej txheem

Kev sib tsoo tawm steel hlau, ib hom steel pob, nws cov txheej txheem ntau lawm:

Tom qab lub ntsuas ntawm daim puag ncig, nws muab txiav rau hauv cov pob hlau npog raws li qhov ntev ntawm qhov ntev. Lub pob hlau tsis muaj vov khoom noj ces yuav muab rau hauv qhov cub ua kom sov kom sov kom sov kom haum. Tom qab ntawd, qhov qhwv plab yog xa mus rau lub pob zeb pob zeb thiab muab dov mus rau hauv lub pob hlau. Cov pob kub kub ntawm cov hlau kub tom qab kev ywj pheej yog quenched thiab tempered los ntawm kev kho cua kub khoom los muab cov hlau npuaj ib lub siab thiab teeb nruj. Tom qab ntawd, cov khoom soj ntsuam thiab muab tso rau cov khoom tiav warehouse tom qab kuaj.
