Kev cuam tshuam ntawm High - hardness Lub hom phiaj xav tau ntawm cov txheej txheem tsim khoom

 

Kev xaiv raw khoom

Txheej txheem txheej txheem

 

Forging txheej txheem kho: Thaum forging KF47 cov khoom uas muaj siab - hardness yuav tsum, vim muaj ntau dua deformation tsis kam ntawm cov khoom, yuav tsum tau ib tug ntau dua forging kub thiab ntau dua forging siab. Yog tias qhov kub ntawm forging siab dhau lawm, nws yuav ua rau cov qoob loo loj hlob thiab cuam tshuam rau cov khoom lag luam, yog li qhov ntsuas kub yuav tsum tau tswj nruj me ntsis. Piv txwv li, forging kub ntawm cov pa roj carbon zoo tib yam tej zaum yuav yog 1200 - 1250 degree, thaum rau KF47 cov khoom uas yuav tsum tau high-hardness, lub forging kub yuav raug hloov mus rau 1230 - 1280 degree . Nyob rau tib lub sijhawm, qhov sib piv forging kuj yuav tsum tau tswj kom tsim nyog. Feem ntau, qhov sib piv forging yog nyob nruab nrab ntawm 3 - 5 kom ntseeg tau tias cov khoom siv hauv cov khoom sib xws thiab txhim kho hardness thiab lub zog.

 

Casting txheej txheem optimization: Yog tias cov txheej txheem casting yog siv los tsim cov khoom lag luam siab - hardness KF47, kev saib xyuas yuav tsum tau them rau qhov kev sib cais thiab kev faib tawm ntawm cov hlau alloy. Thaum lub sij hawm pouring txheej txheem, lub pouring kub thiab ceev yuav tsum tau tswj kom tsis txhob muaj compositional segregation. Piv txwv li, qhov kub ntawm qhov pouring tej zaum yuav yog 30 - 50 degree siab tshaj ntawm cov khoom zoo tib yam los xyuas kom meej tag nrho cov dissolution ntawm alloy ntsiab. Nyob rau tib lub sijhawm, qhov tsim nyog pouring ceev thiab lub rooj vag tsim yuav tsum tau saws los ua kom cov kua hlau sib npaug ntawm cov pwm kab noj hniav thiab tiv thaiv cov tawv nqaij los ntawm kev cuam tshuam los ntawm kev ntxiv los yog depletion ntawm cov hlau alloy hauv cheeb tsam.

 

Thaum tshav kub kub - kev kho mob

 

Kev kho mob quenching: Quenching yog ib qho tseem ceeb ntawm cov cua sov - kev kho mob rau cov khoom hardness. Rau KF47 cov khoom uas yuav tsum tau muaj siab hardness, ib tug tsim nyog quenching kub thiab txias nruab nrab yuav tsum tau xaiv. Lub quenching kub yog txiav txim siab raws li cov khoom muaj pes tsawg leeg (tshwj xeeb tshaj yog cov ntsiab lus ntawm cov alloy) thiab feem ntau siab dua li cov khoom zoo tib yam. Piv txwv li, qhov kub thiab txias ntawm cov pa roj carbon zoo tib yam yuav yog 800 - 850 degree, thaum KF47 cov khoom yuav tsum tau quenched ntawm 850 - 900 degree . Kev xaiv ntawm qhov nruab nrab cua txias kuj tseem ceeb heev. Cov xov xwm txias tshaj plaws muaj xws li roj, dej, thiab brine. Rau cov khoom uas muaj siab - hardness yuav tsum tau, brine nrog ib tug ceev txias npaum li cas yuav raug xaiv raws li qhov nruab nrab cua txias, tab sis nws yog tsim nyog los tiv thaiv cov khoom los ntawm cracking vim lub dhau - ceev ceev txias npaum li cas.

 

Kev cuam tshuam ntawm Nruab Nrab - hardness Lub hom phiaj xav tau ntawm cov txheej txheem tsim khoom

 

Txheej txheem txheej txheem

 

Forging Parameter Chaw: Thaum forging KF47 cov khoom nrog nruab nrab - hardness, forging kub thiab siab yog me ntsis qis dua cov khoom siab hardness. Lub forging kub yog feem ntau nyob ib ncig ntawm 1150 - 1200 degree, thiab forging piv yog nruab nrab ntawm 2 - 4. Nyob rau hauv txoj kev no, cov khoom siv tuaj yeem tsim tau yooj yim, thiab qhov sib xws ntawm cov qauv sab hauv ntawm cov khoom tuaj yeem khaws cia kom tau raws li qhov nruab nrab - hardness yuav tsum tau.

 

Casting txheej txheem nthuav dav tswj: Thaum siv cov txheej txheem casting, kev tswj ntawm qhov kub thiab qhov ceev tsis yog nruj raws li cov khoom siv hardness siab, tab sis kev faib tawm ntawm cov hlau alloy tseem yuav tsum tau ua kom ntseeg tau. Lub pouring kub feem ntau yog 10 - 30 degree siab tshaj ntawm cov khoom zoo tib yam, thiab lub pouring ceev yuav tsum yog nruab nrab los xyuas kom meej tias cov kua hlau yuav smoothly sau cov pwm kab noj hniav thiab tsis txhob muaj qhov tsis xws luag xws li pores thiab inclusions, uas yuav cuam tshuam rau lub khoom hardness thiab lwm yam khoom.

Thaum tshav kub kub - kev kho mob

 

Quenching Kub thiab txias tswj: Lub quenching kub ntawm nruab nrab - hardness khoom yog qhov tsawg, feem ntau nyob ib ncig ntawm 800 - 830 degree . Qhov nruab nrab cua txias tuaj yeem yog roj lossis dej - soluble quenching nruab nrab, thiab qhov txias txias tuaj yeem ua rau cov khoom kom tau txais qhov nruab nrab hardness. Piv txwv li, roj - cua txias tuaj yeem ua rau cov khoom tau txais cov qauv zoo sib xws thiab nruab nrab hardness thiab zam lub cim ntawm kev ntxhov siab sab hauv vim yog ib yam nkaus - ceev ceev txias.

 

Tsis txhob dhau Hard - theem - tsim cov ntsiab lus: Qhov sib ntxiv ntawm cov ntsiab lus uas nquag tsim cov theem nyuaj yuav tsum raug txo kom tsawg. Piv txwv li, cov ntsiab lus ntawm cov ntsiab lus xws li chromium thiab molybdenum yuav tsum raug txo kom tsawg vim tias cov ntsiab lus no yooj yim rau kev tsim carbides thiab lwm yam nyuaj, uas yuav ua rau kom cov khoom hardness thiab tsis ua raws li qhov tsawg-hardness.

 

Txheej txheem txheej txheem

 

Yooj yim Forging txheej txheem: Thaum forging KF47 cov khoom uas tsis tshua muaj - hardness, qis forging kub thiab siab tau txais yuav tsum tsis txhob ua hauj lwm - hardening ntawm cov khoom. Lub forging kub yog feem ntau nyob ib ncig ntawm 1000 - 1100 degree, thiab forging piv yog nruab nrab ntawm 1.5 - 3. Nyob rau hauv txoj kev no, cov khoom yuav deformed nyob rau hauv ib tug qis zog lub xeev thiab tuav ib tug tsawg hardness.
