Kev them nyiaj yug Technical:Peb tuaj yeem pom zoo cov phiaj xwm loj loj raws li koj cov txheej txheem tshwj xeeb (xws li, xaim noj, tshuab, hauv - kab ua haujlwm).

Khoom siv

1: Cov khoom siv tseem ceeb rau "Instant Inoculation" hauv High-Kev Lag Luam Casting

Nyob rau hauv zus tau tej cov grey cam khwb cia hlau thiab ductile hlau, ntxiv fesi hmoov nrog lub molten hlau thaum lub sij hawm pouring yog ib tug tseem ceeb txheej txheem rau kev txhim kho casting kev ua tau zoo.

Hauv grey cam khwb cia hlau:

Ntxiv 0.1-0.3% ferrosilicon hmoov zoo txhawb kev tsim ntawm hom A graphite, ua kom zoo dua graphite flakes, thiab tshem tawm cov qauv "dawb hlau" ntawm cov npoo casting. Qhov no ua rau kom lub zog tensile ntawm lub casting los ntawm 20-30% thiab zoo heev txhim kho machinability, ua rau nws lug siv nyob rau hauv kev tsim cov khoom tseem ceeb uas yuav tsum tau muaj zog thiab airtightness, xws li tshuab cuab tam txaj, cav blocks, thiab hydraulic valve blocks.

Hauv ductile hlau:

Ntxiv thaum lub sij hawm pouring theem tom qab spheroidization kho, nws ua raws li ib tug inoculant, zoo txhim kho lub roundness thiab kom muaj nuj nqis ntawm graphite spheroids, tiv thaiv distorted graphite, thiab xyuas kom meej cov qauv siab ntawm elongation thiab cuam tshuam toughness nyob rau hauv lub casting. Qhov no yog ib qho tseem ceeb heev rau kev tsim cov cua fais fab castings, automotive chassis qhov chaw, thiab siab - yeeb nkab fittings.

2: "Purifying Agent" nyob rau hauv Tshwj xeeb Steel Smelting thiab Steel Refining

Nyob rau hauv lub ladle refining theem ntawm steelmaking, ferro silicon hmoov yog ncaj qha pub rau hauv qhov tob ntawm lub ladle ntawm ib tug spraying system.

Deep Deoxidation:

Cov hmoov zoo ua rau thaj chaw sib cuag nrog cov hlau molten, ua tiav sai thiab meej deoxidation ntau dua li cov ntaub ntawv loj. Qhov no ua kom yooj yim ntab deoxidized cov khoom, yog li txo cov pa oxygen thiab tsis yog -hlau inclusions nyob rau hauv cov hlau, thiab txhim kho nws purity.

Zoo -tuning Alloy Composition:

Nws tuaj yeem siv los ua cov khoom siv silicon meej hauv kev tsim hluav taws xob silicon steel, siab - lub zog caij nplooj ntoos hlav steel, tshwj xeeb stainless hlau, thiab lwm yam hlau uas yuav tsum tau tswj cov ntsiab lus ntawm silicon.

3: Tshwj xeeb Additive hauv Refractory thiab Tshuaj Industries

Refractory Material Manufacturing:

Hauv siab -kev ua tau zoo recrystallizedsilicon carbide (SiC)refractories, ferrosilicon alloy hmoov tuaj yeem ua kev pabcuam sintering thiab antioxidant additive, txhim kho lub siab - kub lub zog thiab thermal shock tsis kam ntawm cov khoom refractory thiab txuas lub neej rauv.

Magnesium smelting:

Nyob rau hauv cov txheej txheem Pidgeon rau magnesium smelting, ferrosilicon hmoov, vim nws cov reactivity siab, yuav siv tau raws li ib tug zoo txo tus neeg sawv cev.

Welding cov ntaub ntawv kev lag luam:

Siv los ua ib qho alloying tivthaiv nyob rau hauv txheej tshwj xeeb vuam electrodes.

FAQ

Q: Dab tsi yog qhov zoo ntawm kev siv hmoov ferrosilicon piv rau ferrosilicon thaiv?

A:Cov txiaj ntsig tseem ceeb yog cov tshuaj tiv thaiv ceev thiab precision. Hmoov dissolves sai heev, ua tiav "instantaneous" cov teebmeem (xws li inoculation), tso cai rau kom meej meej muaj pes tsawg leeg hloov thiab ntau ruaj khov, ua rau nws tshwj xeeb tshaj yog haum rau automated ntxiv thiab ladle refining.

Q: Yuav ua li cas yog qhov zoo tshaj qhov ntxiv tus nqi txiav txim thaum lub sij hawm casting inoculation?

A:Feem ntau 0.1% -0.3% ntawm molten hlau hnyav. Qhov no yuav tsum tau txiav txim siab sim raws li tus thawj molten hlau muaj pes tsawg leeg, casting phab ntsa thickness, lub hom phiaj microstructure, thiab cov khoom. Tsawg dhau yuav ua rau tsis txaus inoculation, thaum ntau dhau yuav ua rau shrinkage porosity.

Q: Dab tsi yog qhov kev tiv thaiv kev nyab xeeb rau kev cia thiab siv?

A:Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo- qhov cua, kom deb ntawm qhov chaw hluav taws xob thiab oxidizers. Cov hmoov tuaj yeem tsim cov hmoov av tawg hauv huab cua; tawg-cov ntaub ntawv pov thawj kev nyab xeeb yuav tsum tau ua raws thaum lub sijhawm ua haujlwm kom tsis txhob muaj plua plav.
