Pure Iron li Blast Furnace Charge
Cov hlau ntshiab, thaum siv los ua qhov cub tawg, hais txog cov khoom siv hlau zoo uas ua haujlwm tseem ceeb hauv kev tsim khoom ntawm ntau yam hlau thiab hlau.
Txheej txheem cej luam
Cov hlau ntshiab, raws li hom hluav taws xob rau hluav taws xob, muaj cov ntsiab lus hlau siab thiab qib impurity tsawg. Nws feem ntau yog tsim los ntawm cov txheej txheem ua kom zoo kom ntseeg tau tias nws purity thiab haum rau kev siv hauv high-end daim ntawv thov.
Yam ntxwv
-
Cov ntsiab lus hlau siab:
Cov hlau ntshiab siv los ua qhov cub hluav taws xob feem ntau muaj feem pua ntawm cov hlau, feem ntau tshaj 99.95%. Cov ntsiab lus hlau siab no ua kom muaj txiaj ntsig zoo ntawm cov khoom siv hlau thiab hlau.
-
Tsawg Impurity Qib
Cov impurities xws li carbon, sulfur, phosphorus, thiab lwm yam khoom yog nruj me ntsis tswj kom txo tau lawv lub xub ntiag nyob rau hauv cov hlau ntshiab. Cov impurities no tuaj yeem cuam tshuam rau cov khoom ntawm cov khoom siv hlau thiab steel kawg.
-
Kev Txom Nyem Zoo:
Cov hlau ntshiab yog yooj yim txo tau, txhais tau hais tias nws tuaj yeem hloov mus rau hauv cov hlau hlau zoo thaum lub sijhawm tawg rau qhov cub.
Cov txheej txheem ntau lawm
Kev tsim cov hlau ntshiab raws li qhov cub hluav taws xob muaj ob peb kauj ruam tseem ceeb:
Hlau Ore Xaiv
High-quality hlau ore yog xaiv raws li cov khoom siv raw. Cov ore yog cais raws li nws cov tshuaj muaj pes tsawg leeg, xws li oxides, sulfides, thiab carbonates.
Sintering thiab Pelletizing
Cov hlau ore zoo yog agglomerated rau hauv cov ntaub ntawv loj dua, ruaj khov dua los ntawm cov txheej txheem sintering lossis pelletizing. Cov txheej txheem no txhim kho lub cev lub cev ntawm cov ore thiab ua kom nws haum rau siv hauv qhov cub tawg.
Kev txo qis
Hauv qhov cub tawg, cov agglomerated hlau ore raug txo los ntawm kev txo cov neeg ua haujlwm xws li coke lossis thee. Tus neeg sawv cev txo qis reacts nrog cov hlau oxide nyob rau hauv cov ore los tsim hlau hlau thiab gaseous by-products.
Daim ntawv thov
Ntshiab hlau raws li lub cub tawg nqi yog dav siv nyob rau hauv zus tau tej cov hlau thiab steel khoom
01
Hluav taws xob thiab Precision Alloys:
Cov hlau ntshiab yog cov khoom tseem ceeb hauv kev tsim hluav taws xob thiab cov hlau nplaum, uas yog siv rau hauv cov ntawv thov uas xav tau cov khoom sib nqus siab, xws li transformers thiab generators.
.
02
Stainless hlau:
Kev tsim cov hlau tsis huv, tshwj xeeb tshaj yog cov pa roj carbon tsawg thiab ultra-low-carbon stainless hlau, tau txais txiaj ntsig los ntawm kev siv cov hlau ntshiab ua cov khoom siv raw.
03
Hmoov metallurgy:
Cov hlau ntshiab kuj tseem siv rau hauv cov ntawv siv hmoov metallurgy, qhov chaw uas nws tau ua tiav rau hauv ntau yam duab thiab ntau thiab tsawg rau siv rau hauv cov khoom thiab qhov chaw uas yuav tsum tau muaj zog thiab durability.
