Q235 square raj nrog zoo thiab tus nqi qis
Q235 welded square yeeb nkab yog ib qho appellation ntawm square yeeb nkab, uas yog, steel yeeb nkab nrog tib sab ntev. Nws yog ua los ntawm dov sawb hlau los ntawm kev daws teeb meem. Nquag, cov sawb hlau yog unpacked, tiaj tus, curled thiab welded los tsim ib puag ncig yeeb nkab, thiab tom qab ntawd cov yeeb nkab puag ncig yog dov los xyuas cov Q235 welded square yeeb nkab, thiab tom qab ntawd txiav mus rau qhov ntev ntev. Qhov ib txwm yog 50 daim ib pob. Lub zog yog hais txog kev ua haujlwm ntawm Q235 welded square raj los tiv thaiv kev puas tsuaj (tsim yas deformation lossis tawg) nyob rau hauv cov khoom zoo li qub. Vim tias cov ntaub ntawv ntawm kev ua haujlwm muaj xws li nro, contraction, meandering, shear thiab lwm yam, vim hais tias lub zog kuj muab faib ua tensile zog, compressive zog, flexural zog, shear zog thiab lwm yam. Feem ntau muaj kev sib raug zoo ntawm ntau lub zog. Hauv kev siv ib txwm, lub zog tensile yog qhov ntsuas lub zog tshaj plaws. Lub zog tiv thaiv lub zog ntawm kev puas tsuaj, uas yog hu ua storming toughness.
Lub load rau ntawm qhov chaw uas muaj kev vam meej yog hu ua tus nqi thiab ntxiab load. Lub zog, plasticity thiab lub kaum sab xis tham tom qab yog lub tshuab ua haujlwm ntsuas ntawm Q215 welded square yeeb nkab nyob rau hauv static load. Nyob rau hauv kev xyaum, ntau lub tshuab tshuab yog nyob rau hauv rov qab load, thiab tag nrho lub sij hawm yog nkees nyob rau hauv no ib puag ncig. Fatigue angle yog ib rab koob ntsuas los ntsuas qhov muag muag thiab nyuaj ntawm cov ntaub ntawv hlau. Nyob rau hauv xyoo tas los no, feem ntau tsis tshua siv sab hauv lub kaum sab xis txiav txim siab txoj kev yog xovxwm nyob rau hauv lub kaum sab xis txoj kev. Nws siv lub indenter nrog ib tug xov tooj thiab cov duab los nias rau hauv cov ntaub ntawv nto ntawm Q235 welded square raj nyob rau hauv ib tug tej yam load, thiab sab hauv txiav txim nws lub kaum sab xis tus nqi raws li cov xovxwm nyob rau hauv theem. Cov kev siv feem ntau suav nrog Brinell lub kaum ntse ntse (HB), Rockwell lub kaum ntse ntse (HRA, HRB, HRC) thiab Vickers kaum (HV). Angular plasticity hais txog lub zog ntawm cov yas deformation (mus tas li deformation) yam tsis muaj kev puas tsuaj ntawm cov ntaub ntawv hlau hauv qab load. Yas Q215 welded square raj uas tsis yog-tus qauv seamless square raj yog extruded los ntawm seamless ncig raj. Qhov sib txawv ntawm seamless thiab welded square raj yog literal. Nws yog ib hom square tube (rectangular tube). Tus ntsuj plig ntawm ntau cov ntaub ntawv tuaj yeem tsim lub cev ntawm square tube (rectangular tube). Nws qhov nruab nrab yog, vim li cas thiab qhov twg nws siv. Feem ntau Q215 welded square tubes yog steel tubes, feem ntau cov qauv square tubes, whitewashed square tubes, lub tsev square tubes (rectangular tubes), thiab lwm yam
Qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Txawm li cas los xij, piv nrog cov kab ncaj nraim square yeeb nkab nrog tib qhov ntev, qhov ntev vuam nce 30 ~ 100%, thiab qhov ceev ceev yog tsawg.
Welded square kav nrog loj los yog tuab txoj kab uas hla feem ntau yog ua los ntawm steel dawb paug ncaj qha, thaum me me welded kav thiab nyias-walled welded kav tsuas yog yuav tsum tau welded ncaj qha los ntawm steel sawb. Tom qab ntawd tom qab polishing yooj yim, hlau kos duab yog OK. Yog li ntawd, ncaj seam welding feem ntau yog siv rau me me-inch welded kav, thiab kauv vuam feem ntau yog siv rau loj-inch welded kav.
Cov khoom siv ntawm welded square kav yog: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 01cr18, etc.
Welded stainless hlau yeeb nkab rau kho kom zoo nkauj (GB / T 18705-2002), stainless hlau welded yeeb nkab rau lub tsev kho kom zoo nkauj (JG / T 3030-1995), txoj kab uas hla loj welded steel yeeb nkab rau cov dej tsis tshua muaj siab (GB / T 3091-2001), thiab welded steel yeeb nkab rau tshav kub exchanger (yb4103-2000).
