1.Initial theem (1920 -1950 s)
Qhov kev lag luam tau pib nyob rau hauv 1920s, nrog thawj zaug seamless steel yeeb nkab dov hauv 1953.
Ansteel, raws li lub menyuam txaj ntawm lub sector, qhia txog cov kws kho tshuab soviet thiab cov kws tshaj lij, tso lub hauv paus rau kev txhim kho.
2. Kev Tsim Nyog Zoo Rau Tus Kheej (1960 -1970 s)
Domestically produced φ100mm Tube Rolling Rolling MILLS tawm, thiab high zaus vuam hloov kev siv tes vuam vuam.
Cov qauv tsim qauv tau tsav thoob tebchaws supildwide.
3.Pos-hloov kho thiab qhib kev hloov kho tshiab
Advanced technologies Zoo li kev txuas ntxiv rolling mills tau qhia, nqa cov khoom siv rau cov qauv thoob ntiaj teb.
4.Global Leadership nyob rau 21st caug xyoo
Tuam Tshoj tau dhau los ua neeg tsim khoom ntiaj teb thiab cov neeg siv khoom ntawm cov kav dej hlau, nrog kev tso zis mus ze 80 lab tons hauv 2013 (70% ntawm kev tsim khoom thoob ntiaj teb).
Nyob rau hauv xyoo tsis ntev los no, kev tsim khoom tau stabilized nyob ib ncig ntawm 50 lab tons, feem ntau siv hauv av, tshuab, nrog cov zog hluav taws xob ntawm txog li ntawm 9 lab tons.
Tuam Tshoj tus kab yeeb nkab steel tau hloov zuj zus los ntawm kev taw qhia kev hloov pauv thiab cov kev txhim kho thoob ntiaj teb, txhawb nqa kev tsim kho tshiab thiab kev thov kev xa tawm.
