441 silicon hlau (Si 441) yog cov ntsiab lus tseem ceeb tshaj plaws thiab siv dav hauv qib metallurgical silicon. Nws lub npe "441" ncaj qha txhais nws qhov tseem ceeb impurity txwv: Hlau (Fe) Tsawg dua lossis sib npaug li 0.4%, Aluminium (Al) Tsawg dua lossis sib npaug li 0.4%, thiab Calcium (Ca) Tsawg dua lossis sib npaug li 0.1%. Qhov tshwj xeeb tshuaj muaj pes tsawg leeg ua tiav qhov sib npaug zoo ntawm purity, kev ua tau zoo, thiab tus nqi. Nws zam qhov kev pheej hmoo ntawm kev ua tau zoo uas cuam tshuam nrog cov impurities ntau dhau hauv qis- qib silicon hlau (xws liSilicon 553) thaum tseem zam cov nqi kim kim ntawm siab -purity silicon (xws liSilicon 2202), ua rau nws yog ib qho khoom siv zoo tshaj plaws rau loj- nplai ntau lawm hauv ntau qhov kev lag luam.

Vim li cas thiaj xaiv 441:Nws cov purity nruab nrab thiab nruj impurity tswj xyuas kom meej lub purity ntawm molten steel, tsis txhob muab cov kev taw qhia ntawm ntau yam teeb meem impurities, thiab ua tau raws li qhov yuav tsum tau ntawm ntau lawm stainless steels (xws li 304, 316, thiab lwm yam qib).

silicon 441 daim ntawv thov tseem ceeb

1: Core Alloying Element nyob rau hauv Cast Aluminium Alloys

Qhov no yog qhov loj tshaj plaws thiab feem ntau classic daim ntawv thov ntawm 441 metallic silicon. Silicon (Si) yog ib qho tseem ceeb ntawm cov hlau alloying hauv txhuas alloys, tshwj xeeb tshaj yog tuag- nrum txhuas alloys (xws li ADC12 thiab A380) thiab forged aluminium alloys.

Muaj nuj nqi:

Ntxiv silicon tuaj yeem txo qis qhov kub ntawm cov hlau, txhim kho cov dej ntws thiab cov khoom ntim ntawm cov yaj, thiab txo qhov tsis xws luag. Ib txhij, silicon tuaj yeem txhim kho qhov nyuaj, lub zog, thiab hnav tsis kam ntawm aluminium alloys, tab sis nws yuav txo qis lawv cov ductility me ntsis.

2: Kev tsim khoom tshwj xeeb Ferroalloys thiab Steelmaking Deoxidizer

Silicon hlau yog "cov khoom siv hauv paus" rau kev tsim ntau yam tseem ceeb ferroalloys.

Ferrosilicon alloys:

Cov no yog cov khoom siv tseem ceeb rau smelting mainstreamferrosiliconqib xws liFeSi 75thiabFeSi72. Cov ferrosilicones no tau siv dav hauv kev lag luam hlau ua deoxidizers thiab alloying additives.

Silicon{0}}calcium alloys, silicon{0}}barium alloys, thiab lwm yam:

Cov no yog cov khoom siv silicon rau kev tsim cov khoom sib xyaw deoxidizers thiab inoculants.

Direct deoxidation:

Hauv kev ua kom zoo ntawm qee cov qib steel, silicon hlau 441 hais kuj tuaj yeem siv ncaj qha rau deoxidation.

3: Ntsiab Additive rau NdFeB Permanent Magnets

Hauv kev tsim khoom siab - kawg, 441 silicon yog qhov tseem ceeb ntxiv rau kev tsim cov sintered NdFeB cov hlau nplaum ruaj khov.

Muaj nuj nqi:

Thaum lub sij hawm tsim cov hlau nplaum, ntxiv cov lej ntawm silicon (feem ntau nyob rau hauv daim ntawv ntawmsilicon hlau 441 hmoov) tuaj yeem cuam tshuam cov qoob loo ntau dhau, txhim kho microstructure, thiab yog li txhim kho cov hlau nplaum coercivity (anti-demagnetization peev xwm) thiab siab - kub stability.

Purity Requirements:

Qhov qis titanium (Ti) thiab qis calcium (Ca) cov khoom ntawm qib 441 yog qhov tseem ceeb rau kev ua kom muaj kev sib luag thiab sib xws ntawm cov hlau nplaum ua haujlwm; ntau impurities yuav impair magnetic zog.

4: Alloy Additive nyob rau hauv stainless hlau thiab tshwj xeeb hlau ntau lawm

Hauv kev lag luam steel, silicon hlau yog siv los tsim cov hlau tshwj xeeb xws li stainless hlau, hluav taws xob hlau, thiab lub caij nplooj ntoos hlav steel.

Hauv stainless hlau:

Silicon yog ib qho tseem ceeb ntawm cov hlau alloying, pab txhim kho cov hlau oxidation tsis kam, corrosion kuj, thiab lub zog ntawm qhov kub thiab txias.
