Tom qab thib peb lub rooj sib tham ntawm 11 THPC Central, Tuam Tshoj muaj kev sib pauv hloov pauv thoob ntiaj teb thiab tshaj tawm cov thev naus laus zis. Starting from the introduction of Baosteel's φ140mm mandrel full floating continuous rolling mill, Tianjin φ250mm mandrel limited continuous rolling mill, Daye φ177mm Axel rolling mill, Chengdu φ180mm precision rolling mill and Hengyang φ89mm mandrel semi-restricted continuous rolling mill have been built successively. Baotou steel's φ140mm tsis siv neeg cov yeeb nkab rolling kev hloov pauv, thiab kuj tau tshaj tawm cov kev hloov pauv thoob plaws φ250mm sawv ntsug (5 thav duab) Mandrel tsawg txuas txuas ntxiv ua ntej siv cov zeb. Cov commissioning ntawm cov hlua dig hniav tau ua peb lub teb chaws seamless
Qib ntawm cov yeeb nkab steel kub kub yob tau tsa mus rau hauv theem thoob ntiaj teb lub sijhawm ntawd.
Txij li Tuam Tshoj ntawm kev lag luam yeeb nkab steel tau nkag mus rau lub xyoo pua 21st, tom qab ntau tshaj 20 xyoo ntawm ntau dua 20 xyoo ntawm kev loj hlob sai, nws tau dhau los ua cov neeg siv hluav taws xob nrawm thiab cov neeg siv khoom. Txij li thaum muaj teeb meem nyiaj txiag hauv xyoo 2008, kev txhim kho ntawm Tuam Tshoj ntawm cov yeeb nkab steel yeeb nkab tau ua tau zoo heev, thiab cov feem ntawm cov khoom tawm hauv lub ntiaj teb tau ruaj khov nyob rau hauv li 70%.
