Smls Steel Yeeb Nkab

ERW cov qib tshwj xeeb steel yog tus cwj pwm los ntawm lawv cov purity siab. Los ntawm de-S, de-P, degassing, Ca kho thiab lwm txoj hauv kev, cov ntsiab lus ntawm S thiab P tuaj yeem tswj tau hauv qab 0,005 feem pua, N cov ntsiab lus tuaj yeem tswj tau qis dua 0.008 feem pua, cov duab ntawm cov kev suav nrog tuaj yeem tswj tau ua kheej kheej, thiab tus lej ntawm cov kev suav nrog tuaj yeem txo qis heev. Cov ntsiab lus C yog tswj tau qis dua 0.1 feem pua, yog li ntawd cov weld nrog rau lub girth weld tsim txheej txheem muaj kev vuam zoo, thiab lub zog nce yog los tiv thaiv kev loj hlob ntawm austenite nplej los ntawm kev ntxiv cov kab sib txuas xws li Nb, V thiab Ti. Nyob rau tib lub sijhawm, qhov chaw ntxiv dag zog yog nce ntxiv los txhim kho qhov toughness thiab lub zog ntawm cov hlau. Lub raj khoob ntawm SMLS steel yeeb nkab feem ntau yog ua los ntawm A3, # 20, 16Mh steel thiab lwm yam ntaub ntawv. Lub purity ntawm cov khoom yog tsawg, thiab cov ntsiab lus C yog siab heev, feem ntau nyob ib ncig ntawm 0.2 feem pua, uas yog tsis conducive rau lub circumference. . welding nyob rau hauv kev tsim kho Qhov kev tiv thaiv yog txais, tab sis tsis zoo toughness.

Lwm qhov sib txawv tseem ceeb ntawm ERW steel yeeb nkab blanks thiab SMLS steel yeeb nkab blanks yog tias yav tas los yog ua los ntawm kub dov steel strips los ntawm txias dov thaum lub tom kawg yog ua los ntawm round steel perforated nyob rau hauv kub dov lub xeev. Pom tseeb, cov nplej loj thiab qhov ntom ntom ntawm SMLS raj dawb paug tsim nyob rau hauv lub xeev kub dov yog qhov sib txawv ntawm ERW raj dawb, thiab cov khoom uas tuaj yeem ua rau qhov no kuj tseem yuav txawv heev.
