Tsis tshua muaj lub ntiaj teb ferro silicon magnesium alloy (RE-FeSiMg) yog ib tug zoo spheroidizing tus neeg saib xyuas optimized los ntawm kev ntxiv lub teeb tsis tshua muaj lub ntiaj teb ntsiab (xws li cerium thiab lanthanum) rau zoo tib yam magnesium silicon ferro alloys. Nws yog dav siv nyob rau hauv zus tau tej cov hlau ductile, vermicular graphite cam khwb cia hlau, thiab siab - zoo cam khwb cia hlau.

Lub luag haujlwm tshwj xeeb ntawm lub ntiaj teb tsis tshua muaj:

Piv nrog cov tshuaj spheroidizing zoo tib yam, qhov sib ntxiv ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb coj peb qhov zoo:

Resisting spheroidization fading:Cov ntsiab lus tsis tshua muaj hauv ntiaj teb tuaj yeem txuas ntxiv lub sijhawm zoo spheroidization, ua rau nws tsim tshwj xeeb rau kev tsim cov tuab -section ductile hlau castings (xws li cua turbine hubs thiab pwm loj), tiv thaiv graphite distortion hauv cov tub ntxhais.

Purifying molten hlau:Cov ntsiab lus tsis tshua muaj hauv ntiaj teb muaj kev sib raug zoo rau cov teeb meem xws li oxygen thiab sulfur hauv molten hlau, ua lub luag haujlwm hauv kev pab desulfurization thiab deoxidation, ntxiv purifying cov hlau molten thiab txhim kho tag nrho cov kev ua tau zoo ntawm cov castings.

Txhim kho graphite morphology:Cov ntsiab lus tsis tshua muaj hauv ntiaj teb tuaj yeem ua rau graphite spheres ntau qhov sib npaug, me dua, thiab sib npaug sib npaug, yog li txhim kho lub zog, elongation, thiab cuam tshuam rau cov hlau nplaum.

FAQ

Q1: Dab tsi yog qhov txawv ntawm lub ntiaj teb tsis tshua muaj FeSiMg alloy thiab zoo tib yam magnesium silicon ferro alloy (tsis muaj lub ntiaj teb tsawg)?

A1: Qhov tseem ceeb sib txawv yog nyob rau hauv qhov tsis kam mus rau fading thiab purification nyhuv ntawm molten hlau.

Ordinary MgSiFe alloy: Haum rau dav me me thiab nruab nrab - qhov loj ntawm cov hlau txuas, nrog tus nqi qis.

Lub ntiaj teb tsis tshua muaj ferro magnesium silicon alloy: Muaj cov ntsiab lus tsis tshua muaj hauv ntiaj teb (xws li Ce thiab La). Rare ntiaj teb cov ntsiab lus tuaj yeem:

Txuas lub sij hawm spheroidizing zoo, tshwj xeeb tshaj yog haum rau tuab thiab loj -section castings.

Ua ke nrog cov kab mob tsis zoo xws li oxygen, sulfur, lead, thiab bismuth hauv cov hlau molten, ua si lub luag haujlwm huv thiab txhim kho lub zog thiab qaug zog ntawm cov hlau hlau.

Ua graphite spheres rounder thiab me dua.

Yog tias koj cov khoom lag luam yog cua tshuab hluav taws xob, qhov tseem ceeb ntawm kev ruaj ntseg tsheb, lossis muaj kev ua haujlwm nruj, peb xav kom siv lub ntiaj teb tsis tshua muaj magnesium-silicon ferroalloy.

Q2: Dab tsi yog qhov tshwm sim yog tias tus neeg sawv cev spheroidizing tau ntub? Nws puas tseem siv tau?

A2: Tsis txhob siv cov tshuaj damp spheroidizing kiag li! Magnesium nyob rau hauv tus neeg sawv cev spheroidizing yog heev reactive; Thaum raug cov dej noo, nws reacts nrog dej los tsim magnesium hydroxide thiab tso hydrogen gas. Qhov no ua rau:

Kev txo qis hauv cov ntsiab lus magnesium zoo, ua rau spheroidization tsis ua haujlwm.

Cov roj hydrogen uas ua tau yog nqus los ntawm cov hlau molten, tsim cov khoom tsis xws luag xws li porosity thiab dawb cam khwb cia hlau.

Cov tshuaj tiv thaiv tuaj yeem ua rau muaj zog heev thaum lub sijhawm ua haujlwm, uas tuaj yeem ua rau tawg thiab raug mob.

Thov xyuas kom meej tias nws khaws cia rau hauv qhov chaw qhuav, zoo -ventilated warehouse. Nws yog qhov zoo tshaj rau ci nws ntawm qhov kub qis ntawm 100-150℃ua ntej siv.

Q3: Yuav ua li cas txiav txim siab qhov ua tau zoo ntawm kev kho spheroidization?

A3:Ntawm qhov chaw tsim khoom, qhov kev txiav txim ua ntej tuaj yeem ua tau los ntawm kev soj ntsuam sai sai ntawm qhov tawg ntawm daim duab peb sab:

Zoo spheroidization: Cov pob txha tawg yog silvery- grey, nrog cov nplej zoo thiab zoo ib yam, pom tseeb shrinkage porosity nyob rau hauv nruab nrab, thiab lub suab tawv zoo ib yam li hlau thaum ntaus.

Deteriorated spheroidization/non-spheroidization: Cov pob txha tawg yog tsaus grey los yog dub, nrog cov nplej ntxhib, me me los yog tsis muaj shrinkage porosity hauv nruab nrab, thiab lub suab nrov thaum ntaus.

Qhov kawg kev pom zoo tseem yuav tsum tau metallographic microscopy los kuaj tus nqi graphite spheroidization.

Q4: Koj qhov kev txiav txim yam tsawg kawg nkaus (MOQ) yog dab tsi? Koj puas tuaj yeem muab cov qauv rau kev kuaj?

A4: Raws li lub hauv paus chaw tsim khoom, peb txhawb cov foundries hauv kev ua me me - batch pov thawj. Tus MOQ rau cov qauv qib feem ntau yog ib lub thawv. Peb kuj zoo siab muab 1-5 kg cov qauv dawb rau koj los kuaj qhov muaj pes tsawg leeg, qhov loj me, thiab cov teebmeem spheroidization hauv koj qhov chaw kuaj lossis qhov cub me me.
