Okwangoku, iibhobho zensimbi zisetyenziswa ngokubanzi kwaye zineentlobo ezininzi.Umbhobho wokwandisa i-Thermal carbon steel yenye yazo.Ineenzuzo ezininzi, kodwa ngokuqinisekileyo ayikho ngaphandle kokungalungi.Oku kulandelayo yinkcazo eneenkcukacha yeenzuzo kunye nokungalunganga kwimibhobho yentsimbi eshushu eyandisiweyo ngeabavelisi carbon steel pipe, ngethemba lokukunceda uqonde le mveliso.

Izinto ezilungileyo zeukwanda kwe-thermalumbhobho wentsimbi yekhabhoni:

Iyakwazi ukutshabalalisa ukwakhiwa kwesakhiwo sombhobho wensimbi, ukucokisa ubungakanani beenkozo zombhobho wentsimbi okhuliswa ukushisa, ukuphelisa iziphene ze-microstructure, ukwenza umbhobho wensimbi owenziwe ukushisa udibanise kwisakhiwo kunye nokuphucula iimpawu zomatshini.Olu phuculo lubonakaliswa ikakhulu kwicala lokuqengqeleka, ukuze umbhobho wentsimbi owandiswayo ubushushu awusenayo i-isotropy ehambelanayo, kunye namaqamza, iintanda kunye ne-porosity eveliswe kwinkqubo yokugalela nayo inokudityaniswa phantsi komsebenzi wobushushu obuphezulu kunye noxinzelelo oluphezulu. .

Ukungalungi kweukwanda kwe-thermalumbhobho wentsimbi yekhabhoni:

1. Uxinzelelo olushiyekileyo olubangelwa kukupholisa okungalinganiyo.Ukuxinezeleka okushiyekileyo kubhekiselele kuxinzelelo lwangaphakathi lokuzilinganisa ngaphandle kwamandla angaphandle.Uxinzelelo olunjalo olushiyekileyo lukhona kwimibhobho yentsimbi eyongeziweyo enobushushu yamacandelo ahlukeneyo.Ngokuqhelekileyo, ubukhulu becala ubukhulu becandelo lentsimbi yecandelo, lukhulu loxinzelelo olushiyekileyo.Uxinzelelo olushiyekileyo luyi-self-phase equilibrium, kodwa lusenempembelelo ehambelanayo kwiimpawu zentsimbi phantsi kwesenzo samandla angaphandle.Imiba efana ne-deformation, i-non-chaos, ukumelana nokukhathala, njl.

2. Emva kokwandiswa kwe-thermal, i-non-metallic inclusions (ikakhulukazi iqulethwe ngama-sulfides kunye ne-oxides kunye ne-silicates) kwipayipi yensimbi yokwandisa i-thermal igxininiswe kumaphepha amancinci, okubangela i-delamination (i-interlayer).I-Delamination iya konakalisa kakhulu iipropathi eziqinile zombhobho wentsimbi owandiswa ubushushu ecaleni kwendlela yobunzima, kwaye xa i-weld icutheka, ukukrazuka kwe-interlaminar kunokwenzeka.Uxinzelelo oluyinxenye ngenxa ye-welding shrinkage idla ngokuphindwe kaninzi kuxinzelelo lwenqaku lesivuno kwaye liphezulu kakhulu kunoxinzelelo oluyinxenye ngenxa yomthwalo.
