Muaj pes tsawg leeg: Cov ntsiab lus carbon yog 0.17% -0.23%, silicon cov ntsiab lus yog 0.17% -0.37%, thiab manganese cov ntsiab lus yog 0.35% -0.65%.
Nta: Nws muaj zog dua thiab hardness, tab sis me ntsis inferior plasticity thiab toughness, thiab yog haum rau siab dua thiab kub tej yam kev mob.
Siv cov xwm txheej
Boiler dej-txias phab ntsa raj: tiv taus lub tshav kub ntawm cov roj kub kub hauv lub boiler, hloov mus rau hauv dej los ua chav dej, thiab xav kom cov raj muaj qhov kub thiab txias tsis kam.

Boiler superheater tubes: siv los ntxiv cov cua sov saturated chav rau hauv chav superheated, xav kom cov raj muaj zog thiab ruaj khov nyob rau hauv qhov kub thiab txias.

Boiler economizer raj: rov qab cov khoom pov tseg hauv cov pa roj thiab txhim kho thermal efficiency, yuav tsum tau cov raj kom muaj thermal conductivity thiab corrosion kuj.

Chav locomotive pipelines: suav nrog cov kav dej superheated thiab cov kav dej kub npau npau, siv los xa cov cua kub thiab cov cua kub siab thiab cov dej kub, xav kom cov raj muaj lub zog zoo thiab kub ua haujlwm.

Hauv luv luv,GB3087 seamless steel kavyog qhov tseem ceeb hauv kev lag luam qis thiab nruab nrab siab boiler. Los ntawm kev xaiv cov khoom tsim nyog thiab cov txheej txheem tsim khoom, kev ua haujlwm zoo thiab kev nyab xeeb ntawm lub boiler tuaj yeem txhim kho kom tau raws li qhov xav tau ntawm ntau yam kev ua haujlwm.
