I-alloy 400 iinxalenye zihambisa ukuchasana kokugqwala okungafaniyo kwiikhemikhali ezinobundlobongela, elwandle, kunye neendawo eziphezulu ze-chloride-ingakumbi apho iintsimbi ezingenasici zihluleka. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siye sasebenza ngoomatshini ngaphezu kwe-12,000 ye-Alloy 400 yamacandelo ukususela ngo-2018 kwimizimba yevalvu yoxinzelelo lwe-hydraulic, i-offshore pump housings, kunye ne-compressor yegesi emuncu yangaphakathi. Inxalenye nganye iqala nge-ASTM B164-certified billet, ifumana i-annealing yokunciphisa uxinzelelo ngaphambi kokuba i-CNC ijike, kwaye igqibe ngeRa ≤0.8 μm ingqibelelo yomhlaba-akukho ngaphandle.
Kutheni iinxalenye ze-Alloy 400 zigqwesa ezinye iindlela kwiNkonzo ye-Real-World
Abathengi bayabuza: "Kutheni ungasebenzisi nje i-316 engenasici okanye i-duplex?" Impendulo ixhomekeke kwindlela yokuziphatha ye-electrochemical-hayi iincwadana ezinemifanekiso yokuthengisa. I-alloy 400 (Ni-Cu, ~ 67% Ni / 30% Cu) ixhathisa ukunciphisa i-acids njenge-hydrofluoric kunye ne-sulfuric apho i-passivation ihluleka. Siye sabona i-valve ye-316 i-corrode kwiinyanga ze-9 ngaphakathi komgca wokudlulisa i-phosphoric acid; i replacement Alloy 400 piston rod yathatha iminyaka 4.7. Ukungakhuseleki kwayo emigodini yamanzi olwandle kunye nokuqhekeka kwe-corrosion ayiyothiyori-iqinisekisiwe kwilebhu yethu eqinisekisiweyo ye-ISO 17025 kusetyenziswa uvavanyo lokuntywiliselwa lwe-ASTM G36 kunye novavanyo lwe-ASTM F1113 olucothayo.
Kodwa i-Alloy 400 ayisiyo-plug-and-play. Izinga lokuqina kwayo elisezantsi lifuna izixhobo ezikhethekileyo: ukufakwa kwekhabhide ezinobuso obupolishiweyo beharika, ubunzulu obunzulu bokusikwa (≤0.3 mm), kunye nesipholisi sesikhukula kuxinzelelo lwebhari ezingama-65. Omnye umxhasi uzame ukuwenza kwi-legacy lathe ene-HSS tooling-ibangele ireyithi ye-scrap ye-42% kunye namanqaku okuxoxa adlula ukunyamezela kwe-GD&T kwi-±0.025 mm. Ngoku sibandakanya uphononongo lwasimahla lwe-machinability kunye ne-RFQ nganye, ukubeka iflegi kwimiba enokuthi ibe kho njengodonga olubhityileyo okanye ukungahambelani kolwandiso lobushushu ngexesha lonyango lobushushu.
Apho Ukuchaneka koMatshini Kudibana ne-Corrosion-Critical Geometry
Uninzi lweentsilelo azenzeki kukhetho lwezinto ezibonakalayo-kodwa ukwenziwa kwejometri. Indawo yokutywina engalungelelaniswanga kakuhle kwi-Alloy 400 yomzimba wevalve yoxinzelelo inokukhawulezisa ukubola kwemingxuma ngama-300%. Yiyo loo nto inkqubo yethu ifakela i-metrology kwizigaba ezithathu: ukuqinisekiswa kwangaphambili kweCMM yokuqina kwesitokhwe ekrwada, umlinganiselo wenkqubo yokubona ukuchaneka kokuchaneka komsonto (okubalulekileyo kwi-API 6A izikhondo zevalvu yesango), kunye nokuqinisekiswa kokugqiba komphezulu wokugqibela nge-interferometry yokukhanya okumhlophe.
Sihlala sivelisa iinxalenye eziyehlayo abaxhasi bemigangatho: 120-mm-diameter I-alloy 400 cylinder liners kunye ne-0.01 mm ukutyeba kodonga oluguquguqukayo kwi-450 mm ubude; amabhobho empompi angajikeleziyo afuna i-±0.008 mm cylindricity; kunye nemilomo ecociweyo enobunzulu obuyi-0.005 mm phakathi kwemibhobho yokungena nokuphumayo. Olu ayilulo unyamezelo-siyaluqinisekisa. Yonke impahla ethunyelwayo iquka iingxelo ezipheleleyo ezilandeleka ngokwemigangatho ye-NIST, kunye neengxelo zovavanyo lwe-mill ezikhethekileyo ezibonisa owona mxholo we-Cu/Ni/Fe/C—hayi nje “ukungqinelana ne-Special.”
Ukusuka kwiCasa ukuya ekugqityweni: Kutheni ukudityaniswa okuthe nkqo kubalulekile
Abanye abathengisi bakhupha i-Alloy 400 beyiphosa emva koko bayimatshini. Asazi. Ngoba? Ngenxa yokuba ulwahlulo lwe-dendritic kwi-Alloy 400 ye-Alloy idala imimandla ye-Cu-etyebileyo ethanda ukuhlaselwa okukhethekileyo. Inkqubo yethu yokulahla isanti isebenzisa amazinga okuqinisa okulawulwayo kunye ne-post-cast homogenization kwi-1150 ° C kwiiyure ze-4-iqinisekiswe ngokuhlalutya kwe-microprobe. Oku kuphelisa i-banding, iqinisekisa i-uniform ye-67.2 ± 0.3% ye-Ni, kwaye ihambisa ubunzima obuhambelanayo (130-160 HBW) kulo lonke icandelo.
Olu lawulo ludlulela ekugqityweni. I-Electropolishing isebenza kakubi kwi-Alloy 400 ngenxa ye-microstructure yayo yezigaba ezimbini. Endaweni yoko, sisebenzisa i-proprietary citric-nitric passivation blend elandelwa ngukucoca nge-ultrasonic emanzini ahlanjululweyo-aqinisekisiwe nge-ASTM A967 Indlela D. Abathengi babika i-2.3 × ubomi obude benkonzo kwi-loops yokupholisa i-chloride-laden xa kuthelekiswa nezinye iindlela eziphuculweyo ngomatshini.
Ukukhetha i-Right Alloy 400 Part Partner-Ngaphandle kwePhepha leDatha
Khangela imiqondiso emithathu: Okokuqala, ubungqina bokuhlalutya kokusilela kwehlabathi-kungekhona nje iingxelo zokuthotyelwa. Sigcina ilog yoluntu yophando lwengcambu (engaziwa) egquma i-hydrogen embrittlement kwinkonzo ye-H₂S kunye nokudibanisa igalvanic kunye neeflange zensimbi zekhabhoni. Okwesibini, ulawulo lwenkqubo ebhaliweyo: Ngaba luchaza ixesha lokufunxa i-annealing? Izinga lokupholisa? Ubungakanani obuziinkozo bokuqinisekisa ngokwe-ASTM E112? Okwesithathu, ukuphendula kwii-callouts ze-GD&T-ingakumbi iprofayili, ukuphuma, kunye nesikhundla esidibeneyo. Ukuba umzobo wakho uxela izilungisi zeMMC okanye izilingisi zedatum, iqela labo lokucaphula kufuneka lithethe olo lwimi ngokutyibilikayo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngolu hlobo kuba iindawo ezikwaziyo ukumelana nomhlwa ayizompahla. Bangabancedisi benkqubo. I-alloy eyodwa ye-400 inxalenye engaphumeleli kwimodyuli yokulawula i-subsea inokubangela i-$ 2.4M kwiindleko zokunciphisa ixesha. Yiyo loo nto siphatha yonke iodolo-ukusuka kwiprototype ukuya kwimveliso-njengeyona nto ibalulekileyo. Sithumela iinxalenye ze-Alloy 400 kuMntla Melika, eYurophu, nakumazantsi-mpuma e-Asia ngokulandelelwa kwezinto ezibonakalayo, isiqinisekiso sobukhulu, kunye nenkxaso yobunjineli eyakhelwe kwisicatshulwa-engafakwanga njengentlawulo eyongezelelweyo.
Ngezicelo ezifuna i-zero compromise on corrosion resistance, dimensional fidelity, and metallurgical consistency-Alloy 400 parts from QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. zenzelwe ukwenza, ziqinisekisiwe ukungqina, kwaye zinikezelwe ukugcina iinkqubo zisebenza.
