Steelmaking thiab Refining: S890QL1 pib nrog melting hlau ore thiab seem nyob rau hauv ib tug steelmaking rauv, ua raws li theem nrab refining los kho chemistry, txo impurities, thiab xyuas kom huv si.
Casting: Cov hlau molten yog cam khwb cia rau hauv slabs, paj, los yog billets, uas yog soj ntsuam rau sab hauv soundness.
Cua sov thiab Thermomechanical Rolling: Cov slabs tau rov ua dua thiab raug tswj kom dov (thermomechanical processing) los kho cov qauv nplej thiab tsim kom muaj zog ua ntej.
Quenching: Tom qab dov, cov phaj yuav txias sai heev (quenched) siv dej los yog polymer los ua ib qho nyuaj, zoo -grained martensitic microstructure.
Tempering: quenched daim hlau yog tempered ntawm ib tug nruab nrab kub los txo cov residual kev nyuaj siab, txhim kho toughness thiab ductility, thiab stabilize lub kawg mechanical zog.
Tiav thiab Kev Tshuaj Xyuas: Cov khoom siv tau ncaj nraim, txiav, kho qhov chaw, thiab tsis yog -kev kuaj kev puas tsuaj (NDT) kom ntseeg tau qhov tseeb qhov tseeb thiab zoo ib yam.
