Core Advantages thiab daim ntawv thov tus nqi ntawm cov khoom

Calcium silicon alloy inoculants, los ntawm lawv cov teebmeem metallurgical tshwj xeeb, coj cov kev txhim kho tseem ceeb thiab kev ua kom zoo rau cov lag luam foundry.

1. Dual Mechanism of Action: Txhim kho Cast Iron Zoo los ntawm cov hauv paus hniav

Txhawb nqa Nucleation:

Ntxiv nrog rau cov hlau molten, calcium thiab silicon react sai sai, tsim ib tug loj tus naj npawb ntawm CaO me me -Al₂O₃-SiO₂ puas oxides thiab SiC hais, ua hauj lwm zoo li graphite nucleation sites. Qhov no txhawb cov nag lossis daus ntawm graphite hauv ib daim ntawv zoo thiab zoo ib yam (xws li hom A graphite hauv grey cam khwb cia hlau), zoo tiv thaiv kev tsim cov hlau dawb thiab txhim kho lub machinability ntawm castings.

Purifying Molten Hlau:

Calcium muaj chemical reactivity siab thiab nyiam reacts nrog teeb meem cov ntsiab lus sulfur (S) thiab oxygen (O) nyob rau hauv molten hlau, ua kom tsawg -melting-point CaS thiab CaO, uas ntab mus rau lub slag tshem tawm. Cov txheej txheem no txo qis cov teeb meem ntawm leej faj thiab oxygen rau graphitization, tshem tawm cov kev pheej hmoo ntawm "sulfur embrittlement" thiab "oxygen embrittlement," thiab purifying cov hlau molten.

2. Kev txhim kho zoo ntawm Casting Performance

Optimized Graphite Morphology:

Hauv cov hlau nplaum, nws txhim kho tus nqi spheroidization thiab roundness ntawm graphite.

Nyob rau hauv grey cam khwb cia hlau, nws ua rau finer thiab ntau uniformly faib graphite flakes, yog li txhim kho tensile zog thiab hnav tsis kam.

Txo Casting Defects:

Los ntawm kev txhawb graphitization, nws stabilizes ntim hloov thaum lub sij hawm solidification, txo qhov tsis xws luag xws li shrinkage porosity, shrinkage kab noj hniav, thiab subcutaneous porosity, yog li txhim kho qhov ntom ntawm castings.

Txhim khu kev ruaj ntseg:

Lub microstructure tsis tu ncua txo kev ntxhov siab nyob rau hauv castings, uas ua rau me me zoo hloov pauv thiab ntau dua yields nyob rau hauv loj ntau lawm.

Cov lus qhia tseem ceeb ntawm kev siv thiab cov qauv kev nyab xeeb

Kev siv kom raug yog qhov yuav tsum tau ua ua ntej rau kev ua kom muaj txiaj ntsig zoo ntawm cov inoculant thiab ua kom muaj kev ruaj ntseg ntau lawm.

Dosage Control:

Qhov pom zoo npaum li cas yog 0.1% - 0.5% ntawm qhov hnyav hlau molten. Kev kho kom zoo yog tsim nyog raws li lub hom phiaj cam khwb cia hlau qib, thawj molten hlau muaj pes tsawg leeg, thiab qhov kub thiab txias. Tsis txaus ntxiv yuav ua rau inoculation poob thiab dawb cam khwb cia hlau, thaum ntxiv ntau dhau yuav ua rau coarse graphite.

Tiv thaiv Inoculation poob:

Cov nyhuv inoculation diminishes thaum lub sij hawm. Nws raug nquahu kom tswj lub sijhawm los ntawm kev ntxiv rau kev ua tiav ntawm kev nchuav mus rau hauv 30 feeb. Rau kev ua haujlwm ntev - voj voog txuas ntxiv, nws raug nquahu kom siv cov inoculants uas muaj cov khoom siv ntev ntev xws li barium (Ba) kom ntev lub sijhawm.

Cov txheej txheem kev nyab xeeb ua haujlwm:

Calcium reacts hnyav nrog dej. Cov inoculant yuav tsum tau khaws cia kom qhuav (cov dej noo tsawg dua lossis sib npaug li 0.5%) thiab khaws cia kom deb ntawm cov dej noo.

Thaum ntxiv rau cov hlau molten, ua raws li lub hauv paus ntsiab lus ntawm "me me, qeeb, thiab txawm tias" kom tsis txhob muaj kev kub ntxhov ntxiv uas tuaj yeem ua rau molten hlau txaws thiab ua kom cov neeg siv kev nyab xeeb.

Nws raug nquahu kom siv tus kws tshaj lij xaim feeder lossis ntxiv cov cuab yeej kom ua tiav qhov tseeb thiab muaj kev nyab xeeb ntxiv.

Calcium Silicon Alloy Inoculant

FAQ

Q1: Dab tsi yog qhov txawv ntawm calcium -silicon alloy inoculants thiab dog digferrosilicon inoculants?

A1: Qhov sib txawv tseem ceeb nyob hauv qhov sib ntxiv ntawm calcium (Ca). Calcium tsis tsuas yog muab cov chaw nucleation xwb tab sis kuj muaj zog deoxidizing thiab desulfurizing muaj peev xwm, purifying molten hlau - tej yam zoo tib yam ferrosilicon tsis muaj. Yog li ntawd, silicon calcium alloys muaj kev ua tau zoo tag nrho hauv kev txhim kho graphite morphology, txo kev suav nrog, thiab txhim kho cov khoom siv tawv.

Q2: Kuv yuav xaiv daim ntawv tsim nyog li cas (thaiv, granules, lossis hmoov) rau kuv cov txheej txheem casting?

A2: Qhov no nyob ntawm koj cov txheej txheem inoculation.

Hauv -txoj kev kho: Blocks (10-50mm) feem ntau yog xaiv kom yooj yim ntxiv thaum tapping lossis ncaj qha ntxiv rau lub ladle.

Nyob rau hauv -flow inoculation: Fine granules los yog hmoov raug pom zoo, ntxiv instantaneously los ntawm ib tug metering feeder rau optimum anti-fading teebmeem.

Hlau pub txoj kev: Yuav tsum tau siv cov granules tuab ntawm ib tug tshwj xeeb loj, loaded rau hauv cored hlau.

Q3: Kev siv cov calcium ntau npaum li cas -silicon alloy inoculants feem ntau txhim kho cov khoom siv ntawm cov hlau castings?

A3: Kev txhim kho nws txawv nyob ntawm seb cov xwm txheej thiab cov txheej txheem. Noj grey cam khwb cia hlau HT250 ua piv txwv, tom qab inoculation kom raug, lub zog tensile feem ntau yuav nce los ntawm 10% -20%, lub hardness tis yog ntau uniform, lub nyiam rau dawb cam khwb cia hlau yog ho txo, thiab lub machinability yog ho txhim kho. Rau cov hlau ductile, nws tuaj yeem txhim kho qib spheroidization thiab tus naj npawb ntawm graphite nodules.
