Ib txwm75% ferrosilicon hmoovFeem ntau muaj 1% -2% txhuas, thaum peb cov khoom txhuas cov ntsiab lus tswj tau qis dua 0.3%.

Vim li cas thiaj nqis peev rau kev siv zog los txo cov ntsiab lus aluminium? Vim tias aluminium ntawv alumina suav nrog hauv cov hlau. Cov kev suav nrog no nyuaj thiab nkig, ua rau peb qhov teeb meem:

Stamping tawg:Qhov no yog qhov kev txhawj xeeb loj tshaj plaws rau cov neeg siv khoom ua automotive steel ntawv.

Txo qaug zog lub neej:Qhov no yog ib qho kev txhawj xeeb loj rau cov neeg muas zaub ua lub caij nplooj ntoos hlav steel thiab bearing steel.

Nruam casting nozzle blockage:Alumina tuaj yeem ua raws li cov phab ntsa sab hauv ntawm lub nozzle thaum lub sijhawm casting, ua rau muaj kev cuam tshuam kev cuam tshuam.

Yog li ntawd, yog tias koj tab tom tsim cov qib steel uas yuav tsum tau muaj siab purity (automotive steel ntawv, pipeline steel, caij nplooj ntoos hlav steel, bearing steel), koj yuav tsum siv tsawg -aluminium ferrosilicon.

"Cov qauv kev lag luam rau txhuas cov ntsiab lus nyob rau hauv zoo tib yam ferrosilicon75 feem ntau tsawg dua los yog sib npaug li 1.5% los yog tsawg dua los yog sib npaug rau 2.0%, tab sis cov khoom xa tuaj tiag tiag feem ntau poob ntawm 1.0% thiab 1.5%. Peb Al 0.3 ferrosilicon txo cov ntsiab lus txhuas kom qis dua 0.3%. Qhov no '0.3%' txhais li cas?

Siv cov ferrosilicon zoo tib yam (Al 1.5%) rau deoxidation, ntxiv 2 kg ib tuj hlau qhia kwv yees li 0.002% -0.003% alumina inclusions.

Siv Al 0.3 ferrosilicon, ntxiv tib 2 kg qhia tsuas yog ib qho - tsib ntawm txhuas.

Rau qhov zoo tib yam rebar, qhov sib txawv no yog negligible. Tab sis rau automotive steel thiab pipeline steel, qhov sib txawv ntawm 0.001% tuaj yeem yog qhov sib txawv ntawm qhov ua tau zoo thiab qhov tsis zoo. "

Kev siv tseem ceeb

Deoxidizer:

Cov tshuaj affinity ntawm silicon thiab oxygen yog qhov loj heev, uas tuaj yeem tshem tawm cov pa oxygen los ntawm cov hlau molten, txhim kho cov purity thiab zoo ntawm cov hlau, thiab txo cov oxide inclusions hauv steel.

Alloy additives:

Ntxiv fesi75 rau steel tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, txhim kho kev ua haujlwm ntawm cov hlau, thiab tseem ua kom cov hlau nplaum sib nqus ntawm cov hlau thiab txo cov hysteresis poob ntawm cov hlau hloov pauv.

Inoculant:

Nyob rau hauv cam khwb cia hlau ntau lawm, ntxiv fesi 75% txhuas 0.3 tuaj yeem tiv thaiv kev tsim cov carbides hauv hlau, txhawb cov nag lossis daus thiab spheroidization ntawm graphite, thiab txhim kho cov khoom siv ntawm cov hlau cam khwb cia.

Spheroidizer:

Pab tsim cov hlau nplaum nrog cov khoom siv zoo heev, txhim kho lub zog, tawv thiab hnav tsis kam ntawm cam khwb cia hlau.

Magnesium smelting:

Hauv Pidgeon txheej txheem ntawm magnesium smelting, nws yog siv los hloov magnesium hauv CaO・MgO.

Weld pas nrig manufacturing kev lag luam:

Tom qab sib tsoo los yog atomization, nws tuaj yeem siv los ua cov txheej txheem vuam rods.

FAQ

Q: Tus nqi sib txawv ntawm Al 0.3 thiab Al 1.5 ferrosilicon li cas?

A: Al 0.3 yog kim dua li niaj zaus ferrosilicon, nyob ntawm kev ua lag luam. Txo cov ntsiab lus ntawm txhuas los ntawm 1.5% mus rau 0.3% yuav tsum tau ntxiv cov txheej txheem refining, ib txwm nce nqi. Seb nws puas tsim nyog nws nyob ntawm koj qhov khoom muag. Yog tias koj cov hlau muag rau 5000 yuan ib tuj, tej zaum koj yuav tsis xav tias nws tsim nyog; Yog tias koj cov hlau muag rau 10000 yuan ib tuj, siv nyiaj ntxiv rau kev thaj yeeb ntawm lub siab yog qhov tsim nyog.

Q: Koj puas tuaj yeem tswj hwm Al 0.3 cov ntsiab lus hauv qab 0.3%? Kuv txhawj xeeb no batch yuav yog 0.25% thiab tom ntej no 0.35%.

A: Yog. Peb kuaj txhua pawg nrog spectrometer ua ntej xa zaub mov kom ntseeg tau tias cov ntsiab lus txhuas nyob hauv qab 0.3%, nrog kev hloov pauv hauv ± 0.05%. Daim ntawv tshaj tawm kev xeem tau suav nrog cov khoom xa tuaj. Cov neeg muas zaub ua automotive steel nplooj ntawv muaj qhov xav tau siab tshaj plaws rau batch stability; peb tau ua haujlwm ntau thiab tsis muaj teeb meem.

Q: Kuv puas tuaj yeem yuav Al 0.1?

A: Customization yog ua tau, tab sis tus nqi yuav siab dua. Cov neeg siv khoom feem ntau tsuas yog xav tau Al 0.3. Yog tias koj cov hlau muaj cov kev cai tshwj xeeb rau cov ntsiab lus txhuas (xws li hluav taws xob hlau), peb tuaj yeem ua cov khoom tshwj xeeb.
