Dab tsi yog cov yam ntxwv ntawm Q235 khoom?
Q235yog ib hom carbon steel qauv uas muaj qhov tsawg kawg nkaus yield zog ntawm 235 MPa. Nws yog lub npe hu rau nws cov khoom zoo txhua yam, nrog rau kev sib npaug ntawm lub zog thiab ductility, zoo heev weldability thiab formability, thiab nruab nrab corrosion kuj.
Lub npe tag nrho ntawm ERW txheej txheem yog dab tsi?
ERWsawv rau Resistance Vuam. Nws yog ib txoj kev tsim khoom uas txuas mus tas li cov khoom siv hlau los ntawm cua sov rau lawv nrog cov hluav taws xob tam sim no, melting cov hlau ntawm qhov sib koom ua ke.
Dab tsi yog qhov txawv ntawm kev siv kub- dov steel sawb thiab txias- dov steel sawb ua raw khoom?
Kub- dov steel yog pheej yig dua thiab muaj cov ductility zoo dua, tab sis nws qhov chaw yog rougher thiab nws qhov tseeb qhov tseeb yog qis dua. Yog li ntawd, nws yog qhov tsim nyog rau cov qauv tsim thiab cov haujlwm loj uas qhov kev zoo nkauj tsis yog qhov tseem ceeb.Txias-rolled steelyog ua tiav nyob rau hauv chav tsev kub, uas ua rau ib tug smoother nto, muaj zog dua, thiab zoo dua seem raug, tab sis nws kuj tseem kim dua. Yog li ntawd, nws yog qhov zoo tagnrho rau cov ntawv thov uas xav tau siab precision, lub zog, thiab nto tiav.
Lub luag haujlwm tseem ceeb ntawm zinc txheej hauv Q235 ERW kub- dov galvanized welded yeeb nkab yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm zinc txheej hauvQ235 ERW kub- dov galvanized welded yeeb nkabyog los muab kev tiv thaiv corrosion zoo dua los ntawm kev siv dual: thaiv kev tiv thaiv thiab kev tiv thaiv kev txi anode. Qhov no txuas rau cov yeeb nkab txoj kev pab cuam lub neej, ua rau nws ruaj khov thiab haum rau ntau yam kev siv, tshwj xeeb tshaj yog ib puag ncig hnyav.
Puas yog qhov chaw welded ntawm Q235 ERW kub- dov galvanized welded yeeb nkab yuav tsum muaj kev tiv thaiv corrosion tshwj xeeb?
Tsis yog, welded cheeb tsam ntawmQ235 ERW kub- dov galvanized welded yeeb nkabFeem ntau tsis tas yuav muaj kev tiv thaiv tshwj xeeb corrosion vim tias zinc txheej muab kev tiv thaiv rau tag nrho cov yeeb nkab, suav nrog cov vuam seam.
