Ntsiab Cai
- - Kev tsim hluav taws xob-steel tau hloov zuj zus rau ntau tshaj ib puas xyoo; core evolution khiav: kub-kuav los tiag silicon steel → pa txias-kuav los tiag hluav taws xob hlau → niaj hnub luv-txoj kev txheej txheem nrog rau CDCM.
- - Upstream innovations tsom rau nyias-slab casting thiab ncaj dov los txiav lub zog noj thiab txhawb cov txiaj ntsig ua ntej cov kab tiav. Kev nce qib hauv qab txhawb nqa ncaj qha dov mus rau qhov kawg tuab thiab tshem tawm qhov nruab nrab annealing.
- - CDCM (nruab nrab pickling thiab txias dov nyob rau hauv ib kab) yog dav siv rau cov uas tsis yog-oriented hluav taws xob steel, shortening ntau lawm txaus thiab txhim kho thickness kam rau ua zoo sib xws.
- - Semi-txheej txheem tsis-oriented hluav taws xob hlau tseem tuav lag luam tus nqi rau cov cheeb tsam uas muaj ntau lub tshuab me me thiab nruab nrab; qhov kawg annealing thiab bluing yog ua tiav ntawm tus neeg siv khoom lub hauv paus-stamping cog.
- - Niaj hnub nimno technologies npog Hi-B grain-oriented steel, laser domain refinement thiab premium low-loss CRNGO qib rau high-efficiency transformers thiab motors.
1. Ib puas xyoo ntawm kev tsim kho tshiab
Ntau tshaj 100 xyoo ntawm hluav taws xob steel ntau lawm keeb kwm kuj yog keeb kwm ntawm kev nruam kev nruam ntej. Thawj qhov kev hloov pauv loj yog kev hloov pauv ntawm kub- dov silicon steel ntawv rau txias- dov hluav taws xob steel sawb. Nrog txoj kev loj hlob ntawm cov nplej- taw qhia cov hlau, qhov tshwm sim ntawm cov inhibitors sib txawv (MnS, AlN) thiab kev kawm tau zoo nyob rau hauv cov dej ntws ntws thiab cov casting, txheej txheem innovation nyob rau hauv ua ntej - txheej txheem txuas ntxiv, thaum tus ncej- txheej txheem tau yooj yim thiab ua tsis tu ncua.
2. Upstream txheej txheem Evolution
Cov txheej txheem dej ntws ntws los ntawm steelmaking thiab refining mus rau cov khoom kub -rolled coils. Feem ntau ntawm cov txheej txheem no hloov pauv yog nyob rau hauv ua ntej- txheej txheem: thinner slabs, txoj kev luv luv thiab ncaj dov, uas txo cov kev siv zog thiab txhim kho cov txiaj ntsig ua ntej cov khoom mus txog cov khoom siv hluav taws xob hlau tiav.
3. Cov txheej txheem nqes hav Evolution
Hauv kev tshaj tawm- txheej txheem, ob qho tib si taw qhia thiab tsis yog- cov hlau taw qhia tau nce zuj zus siv txoj kev ncaj nraim mus txog qhov ua tiav tuab, tshem tawm qhov nruab nrab annealing. Qee cov qib uas tsis yog-cov qhab nia taw qhia siv cov kua qaub- dov tsis tu ncua ntau lawm (CDCM - nruam pickling thiab txias dov nyob rau hauv ib kab), uas ua rau kom cov khoom ntws thiab txhim kho kev ntsuas qhov sib xws.
4. Semi-Cov Txheej Txheem Hluav Taws Xob Hlau
Semi-cov txheej txheem cov khoom tseem nrov nyob rau hauv qee lub khw: tsis yog- cov hom kev taw qhia ntau yam yog tsim nyob rau hauv tsheb-cov ntaub ntawv cov nroj tsuag qis- carbon, qis- cov khoom siv nqi, nrog rau qhov kawg annealing thiab nto bluing ua tiav ntawm lub Hoobkas tseem ceeb. Cov kab khoom no tau tsim los ntawm cov kws tsim khoom hauv tsev hauv xyoo 1980s thiab ib zaug dhau los ua cov khoom tseem ceeb rau kev sib koom ua ke -venture tub yees compressor thiab lub cev muaj zog. Tom qab txoj kev loj hlob sai ntawm txias- dov tag nrho- txheej txheem hluav taws xob steel, cov nqi maj mam poob thiab ib nrab- cov txheej txheem cov khoom maj mam thim tawm ntawm lub khw.
Hauv kev lag luam nrog ntau txhiab tus me thiab nruab nrab- cov tuam txhab loj loj - cov khoom siv me me thiab cov tub ntxhais sib txawv ua rau cov khoom siv hnyav ua tsis tau - ib nrab- cov khoom lag luam tseem cuam tshuam. Cov tub ntxhais uas tsim los ntawm cov khoom siv cov txheej txheem yuav tsum siv cov khoom sib nqus zoo tshaj plaws, ua rau nws muaj zog - txuag cov khoom.
