Abalingisi ngokwezifisoumkhiqizo wokutshala imali we-duplex wensimbi engagqwalikusuka kumkhiqizi wokulingisa waseChina onomshini, ukwelapha ukushisa, nezinsizakalo zokwelashwa kwendawo.
I-RMC metal casting ikhiqizaukunemba cast izingxenye zensimbiezihlala zihlangabezana noma ezeqa okulindelwe ngamakhasimende. Ukufakwa kwe-wax kutshalwa kwezimali okulahlekile kusivumela ukuthi sikhiqize izingxenye zensimbi ezincane ezingamashumi amagremu futhi ezinkulu ezingamashumi amakhilogremu, ngohlu olubanzi lwama-alloys ayinsimbi futhi angeyona ayoni futhi ngokunemba okukhethekile kobukhulu.
Inqubo yokukhipha i-wax elahlekile ikhiqiza izingxenye zensimbi ezinemba eseduze-netha ezivame ukudinga umshini omncane ongeziwe noma ongawudingi. Ukuqeda okuwumphumela nakho kungcono kakhulu kunalokho okufezwa ngezinye izinqubo. Amandla nokuqina kwezingxenye zokusakaza kuzenza zilungele izinhlelo zokusebenza ezimelana nokugqokwa okuphezulu ezidinga izigidi zemijikelezo.
I-Duplex Stainless Steel (DSS) isho insimbi engagqwali ene-ferrite ne-austenite i-accounting ngayinye cishe ngama-50%. Ngokuvamile, okuqukethwe kwezigaba ezincane kudinga okungenani kube ngu-30%. Endabeni yokuqukethwe okuphansi kwe-C, okuqukethwe kwe-Cr kungu-18% kuya ku-28%, futhi okuqukethwe kwe-Ni kungu-3% kuya ku-10%. Ezinye izinsimbi ezingenasici eziyi-duplex nazo ziqukethe izakhi ze-alloying ezifana ne-Mo, Cu, Nb, Ti, kanye no-N.
Ibanga elitholakalayo le-duplex yensimbi engagqwali ku-RMC Casting Foundry: 1.4460, 1.4462, 1.4468, 1.4469, 1.4517, 1.4770, A 890 1C, A 890 1A, A 890, 5 A8 A8 A8 A9A 995 1B, A 995 4A, A 995 5A, 2205, 2507, 022Cr22Ni5Mo3N, 022Cr25Ni6Mo2N
I-DSS inezici zensimbi engagqwali ye-austenitic ne-ferritic. Uma iqhathaniswa ne-ferrite, ine-plasticity ephakeme kanye ne-ductility, ayinakho ukushisa kwegumbi, futhi ithuthukise ngokuphawulekayo ukumelana nokugqwala kwe-intergranular nokusebenza kokushisela, kuyilapho igcina i-brittleness, i-thermal conductivity ephezulu, kanye ne-superplasticity njengensimbi engagqwali ye-ferrite. Uma kuqhathaniswa nensimbi engagqwali ye-austenitic, i-DSS inamandla aphezulu futhi ithuthukise kakhulu ukumelana nokugqwala kwe-intergranular kanye nokugqwala kokucindezeleka kwe-chloride. Insimbi engagqwali e-Duplex inokumelana nokugqwala okuhle kakhulu kwe-pitting futhi iyinsimbi engagqwali eyonga i-nickel.
