Ijometri ingenamthungo yombhobho wentsimbi we-ERW

Ingenamthungo yeERW umbhobho wentsimbiyahlulwe ngokwejometri engenamthungo kwaye ayinamthungo ngokwasemzimbeni.I-geometric ingenamthungo ye-ERW yentsimbi yombhobho kukususa i-burrs yangaphakathi nangaphandle.

Ukususela kwisakhiwo senkqubo yokususa i-burr yangaphakathi kunye nesixhobo sokuphucula okuqhubekayo kunye nokugqibelela, umbhobho wentsimbi ophakathi kunye nobukhulu obukhulu ngaphakathi kokususwa kwe-burr ibe yinto enhle.Ngaphakathi burr inokulawulwa kwi -0.2mm ~ + O.5mm ngoko.Kubhekiselwa kwi-microstructure ye-weld engenamthungo ngaphakathi, kukho umahluko phakathi kwezinto ezisisiseko kunye nommandla we-weld obangela ukuhla kweepropati zoomatshini, imfuneko yokuthatha amanyathelo okwenza iteknoloji efanayo kunye neyongaguqukiyo.Umbhobho wentsimbi we-ERW ngowenkqubo yobushushu obuqhelekileyo bokuwelda kunye nesiphumo sokuthambeka kobushushu, esikufutshane nomphetho wetyhubhu kwaye senza indawo etyhidiweyo, indawo enyibilikisiweyo, indawo eshushu kakhulu, indawo eqhelekileyo, imimandla engaqheleki ngokupheleleyo, imimandla yobushushu. yommandla wesici.Eye yafudumeza kakhulu izicubu zezowuni ngenxa yeqondo lobushushu elingaphezulu kwe-1000, ingqolowa ye-austenite ikhule ngokumangalisayo kwiimeko zokupholisa iya kwenza isigaba esinzima kunye ne-brittle coarse crystalline, ngaphezu kobukho beqondo lokushisa kuya kuvelisa uxinzelelo lwe-welding.Ke ngoko, ukwenziwa kwendawo ye-weld esezantsi kunesiseko sesinyithi sepropathi yomatshini wale meko kungenxa yenkqubo yokunyanga ubushushu obungenamthungo be-weld esebenzisa isixhobo sokufudumeza esiqhelekileyo sasekhaya siya kuthi sifudunyezwe kwi-AC3 (927).), ngoko ubude be-60m, isantya se-20m / min ngexesha lokupholisa umoya, ukupholisa amanzi xa kuyimfuneko.Le ndlela isetyenziselwa ukufezekisa ukupheliswa koxinzelelo, ukuthambisa kunye nokucokisa umbutho ukuphucula iinjongo ze-HAZ mechanical properties.Okwangoku, iyunithi yehlabathi ye-ERW ephuculweyo isetyenziswe ngokubanzi ukusetyenzwa kwe-weld ifumene iziphumo ezilungileyo.Umgangatho awukwazi ukuphikiswa ukuba kungekhona kuphela i-ERW ye-weld ye-weld kunye ne-coefficient ye-weld ye-1, ukuzaliseka kwemibutho yengingqi ye-weld kunye nesiseko sesinyithi somdlalo.
