Insimbi Engagqwali vs. Insimbi Engagqwali Ephindwe Kabili

1. Iyini insimbi engagqwali? Iyini insimbi engagqwali ephindwe kabili?

Insimbi engagqwali yigama elijwayelekile lohlobo lwensimbi engagqwali, futhi izinhlobo zayo zihlukaniswa kakhulu ngokusekelwe esakhiweni esincane. Ezivamile zifaka insimbi engagqwali ye-austenitic (njenge-304, 316) kanye nensimbi engagqwali ye-ferritic. Insimbi engagqwali ye-duplex uhlobo olukhethekile olunesakhiwo esincane esiyingxube ye-ferrite ne-austenite engaba yisigamu.

2. Yiziphi izinzuzo eziyinhloko zensimbi engagqwali ye-duplex?

(1)Amandla aphezulu kakhulu:Amandla ayo okukhiqiza cishe aphindwe kabili kunensimbi engagqwali evamile ye-austenitic, okusho ukuthi ezisetshenziswayo ezifana nemikhumbi yokucindezela, izinto ezincane zingasetshenziswa ukuhlangabezana nezidingo zamandla nokufeza isisindo kanye nokunciphisa izindleko.

(2)Ukumelana okuhle kakhulu nokugqwala kokucindezeleka (SCC):Endaweni equkethe ama-ion e-chlorine, insimbi engagqwali ye-austenitic ejwayelekile (njenge-304) ithambekele kakhulu ekuqhekekeni kokugqwala okucindezelekile, kuyilapho insimbi engagqwali ye-duplex inezinzuzo zemvelo kulokhu, futhi ukusebenza kwayo kungcono kakhulu kunokwensimbi ye-austenitic yochungechunge lwe-300.

3. Ingabe zikhonakukhona yini imikhawulo yensimbi engagqwali ephindwe kabili?

(1) Izinga lokushisa lokusetshenziswa lilinganiselwe:Ngenxa yendawo yayo yokuqina kokushisa okuphakathi njengokuthi “ukuqina kokushisa okungu-475°C”, ngokuvamile ayinconywa ukuthi isetshenziswe isikhathi eside ezindaweni ezinokushisa okuphezulu ezingaphezu kuka-250°C-300°C;

(2) Izidingo zokucubungula okuqinile kanye nokushisela:Umphumela wayo wokuqina komsebenzi obandayo mkhulu, i-plasticity yayo nokuqina kwayo kuphansi kunensimbi engagqwali ye-austenitic, futhi ukwakheka kwayo kunzima kakhulu. Amandla omugqa kanye nezinga lokupholisa kudingeka kulawulwe ngokuqinile ngesikhathi sokushisela ukuze kuvinjelwe ukuna kwezigaba eziyingozi futhi kubhubhise ibhalansi yezigaba ezimbili.

4. Ungakhetha kanjani phakathi kwalokhu okubili?

Uma isimo sesicelo sinezidingo zamandla aphezulu futhi sibhekene nengozi yokugqwala kokucindezeleka kwe-chloride (njengobunjiniyela basolwandle, imishini yamakhemikhali), insimbi engagqwali ye-duplex ingcono kakhulu;

Uma isevisi ihilela amazinga okushisa aphezulu noma idinga ukwakheka okubandayo okuyinkimbinkimbi, insimbi engagqwali ye-austenitic ingafaneleka kakhulu.

Ngamafuphi, insimbi engagqwali kanye nensimbi engagqwali ephindwe kabili ngayinye inezinzuzo zayo, futhi isihluthulelo sokukhetha sisekufaneni ngokunembile izinga lokushisa, ukucindezeleka kanye nendawo egqwalisayo yezimo zokusebenza.
