Tiwbiau Sgwâr Dur A513, Mae'n enw ar gyfer tiwb sgwâr, sef tiwb o hyd cyfartal.Fe'i gwneir o ddur stribed ar ôl ei brosesu a'i rolio.Yn gyffredinol, mae'r stribed yn cael ei ddadbacio, ei lefelu, ei grimpio a'i weldio i mewn i tiwb crwn, sy'n cael ei rolio i mewn i diwb sgwâr ac yna ei dorri i'r hyd gofynnol.Fel arfer 50 ffyn y pecyn.
Tiwbiau Sgwâr Dur A513, Mae yna bwyntiau di-dor a weldio, tiwb sgwâr di-dor yw'r mowldio allwthio tiwb di-dor.Pibell ddur sgwâr, pibell ddur sgwâr wal drwchus, pibell ddur sgwâr diamedr mawr, pibell ddur sgwâr di-dor, pibell ddur sgwâr aloi isel, pibell ddur sgwâr 135 * 135 * 10, pibell dur sgwâr craen twr, pibell ddur sgwâr aloi isel Q345B, 20 # pibell ddur sgwâr di-dor
1. Dadansoddiad perfformiad esbonyddol o diwbiau sgwâr - plastigrwydd
Mae plastigrwydd yn cyfeirio at allu deunydd metel i gynhyrchu dadffurfiad plastig (anffurfiad parhaol) heb ddifrod dan lwyth.
2. Dadansoddiad mynegai perfformiad o tiwb sgwâr - caledwch
Mae caledwch yn fesur o ba mor galed neu feddal yw deunydd metel.Ar hyn o bryd, y dull a ddefnyddir amlaf i bennu caledwch cynhyrchu yw'r dull caledwch indenter, sef defnyddio siâp geometrig penodol o'r pen indenter o dan lwyth penodol i wyneb y deunyddiau metel a brofwyd, yn ôl graddau'r indenter i bennu ei werth caledwch.
Y dulliau a ddefnyddir yn gyffredin yw caledwch Brinell (HB), caledwch Rockwell (HRA, HRB, HRC) a chaledwch Vickers (HV) a dulliau eraill.
3. Dadansoddiad mynegai perfformiad o tiwb sgwâr - blinder
Mae'r cryfder, plastigrwydd a chaledwch a drafodir uchod yn ddangosyddion o briodweddau mecanyddol metelau o dan lwytho statig.Mewn gwirionedd, mae llawer o rannau peiriant yn cael eu gweithredu o dan lwythi cylchol, a gall blinder ddigwydd o dan yr amodau hyn.
4. Dadansoddiad mynegai perfformiad o bibell sgwâr - caledwch effaith
Gelwir y llwyth sy'n gweithredu ar y rhannau ar gyflymder uchel yn lwyth effaith, a gelwir gallu metel i wrthsefyll difrod o dan lwyth effaith yn galedwch effaith.
5. Dadansoddiad mynegai perfformiad pibell sgwâr - pibell ddur sgwâr cryfder, pibell ddur sgwâr wal drwchus, pibell ddur sgwâr diamedr mawr, pibell ddur sgwâr di-dor, pibell ddur sgwâr aloi isel, pibell ddur sgwâr 135 * 135 * 10, pibell dur sgwâr craen twr , pibell dur sgwâr aloi isel Q345B, pibell ddur sgwâr di-dor 20#
Cryfder yw gallu deunydd metel i wrthsefyll methiant (anffurfiannau plastig gormodol neu dorri asgwrn) o dan lwytho statig.Oherwydd y dull llwytho ar ffurf ymestyn, cywasgu, plygu, cneifio, felly mae'r cryfder hefyd wedi'i rannu'n gryfder tynnol, cryfder cywasgol, cryfder plygu, cryfder cneifio ac yn y blaen.Yn aml mae cysylltiad penodol rhwng cryfderau amrywiol, ac yn gyffredinol defnyddir cryfder tynnol fel y pwyntydd cryfder mwyaf sylfaenol.
