GNEE STEEL yog ib lub chaw muag khoom ntiag tug.Rau ntau tshaj kaum xyoo, peb tau muab cov khoom lag luam steel txhim khu kev qha rau ntau lub chaw pabcuam steel thiab cov neeg siv kawg hauv kev ua haujlwm ntawm marine engineering. Peb tau tsim kev koom tes ntev nrog ntau pua lub Hoobkas los xyuas kom meej tias cov khoom no yog tsim los ntawm cov ntaub ntawv zoo thiab muaj kev sib txuam nrog ntau yam qauv thoob ntiaj teb.
Dab tsi yog qhov kev ua tau zoo ntawm Q245R?
q245r yog lub boiler thiab siab hlab ntsha hlau nrog lub ntsiab lus ntawm 245MPa. "Q" sawv cev rau cov ntsiab lus ntawm cov hlau, cov lej hauv qab no sawv cev tus nqi taw tes ntawm MPa, thiab "R" sawv cev rau lub thawv. Nws muaj qhov tshwj xeeb muaj pes tsawg leeg thiab kev ua tau zoo thiab feem ntau yog siv los ua lub nkoj siab. Nyob ntawm kev siv, qhov kub thiab txias, thiab kev tiv thaiv corrosion, cov khoom ntawm lub thawv phaj uas yuav tsum tau xaiv kuj txawv.
