I-Monel 400 machining ifuna ngaphezu kweeprothokholi zensimbi ezingenasici-ifuna intlonipho yendalo yayo yokuqina komsebenzi, i-quirks conductivity ye-thermal, kunye ne-abrasiveness aggressive. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siye ngoomatshini abangaphezu kwe-12,000 kg ye-Monel 400 components ukususela ngo-2020-iivalvu zoxinzelelo ze-subsea manifolds hydraulic, izindlu zepiston pump cylinder pumps high-pressure fracturing units, kunye ne-disensional participating538 iiyunithi eziphantsi kwe-AMScom 7. I-350 ° C yokulayisha ngebhayisikile ayinakuxoxisana. Into esiyifundileyo ayikho ithiyori. Ifakwe kwiipateni zokunxiba izixhobo, iskena sengqibelelo yomphezulu, kunye nolwamkelo oluphindaphindiweyo lwenqaku lokuqala kuzo zonke ii-OEMs zaseMntla zaseMelika.
Qala ngeSixhobo esiLungileyo seJiyometri—hayi nje iiCoatings eziQinisayo
Iivenkile ezininzi zisilela kwi-ultra-high high hardness PVD-coated carbide installers xa ujongana neMonel 400 machining. Kodwa sifumene ukuba ukufakwa okungaphumeleliyo kwakungaphumeleli ekushiseni-babengaphumeleli kwi-edge eyakhelweyo (BUE) kunye ne-micro-chipping kwi-cut cut. Ngoba? IMonel 400’s high nickel content (63–70%) kunye nekopolo (28–34%) zenza incangathi, i-ductile chip edityaniswa nerake ebusweni ukuba ii-engile zoncedo azinzulu kakhulu okanye i-edge prep inoburhalarhume kakhulu. Isisombululo sethu: sebenzisa ii-engile zeraki ezilungileyo (12°–15°), impumlo enkulu iradiya (0.8–1.2 mm), kwaye iphuculwe—kungekhona emhlabeni—imida. Siyakuphepha ukuhoya kabukhali; endaweni yoko, sisebenzisa i-0.02-0.04 mm T-land kunye ne-0.01 mm chamfer. Oku kunciphisa i-edge fracture ngelixa ugcina ulawulo lwe-chip. Ukujika, siqhuba iSandvik CoroTurn® 107 kunye nebakala leGC4325. Ukugaya, i-Mitsubishi APXM410 ene-VP15TF yokugqoka ihambisa ubomi obufanayo besixhobo semizuzu engama-45 kwi-85 m / min-ngokuchasene nemizuzu eyi-18 usebenzisa izixhobo eziqhelekileyo ze-ISO S-grade.
Ukupholisa ayisiyiyo iKhetho-Ngumgca wakho wokuqala woKhuselo
Abanye bakholelwa ukuba i-high-pressure coolant igqithise kwi-Monel 400 machining. Sibonakalise ngenye indlela ngexesha lebhetshi yakutsha nje yeerola ze-winch centre shaft yemoto yobunjineli ye-OEM. Ngaphandle kokupholisa ngesixhobo kwi-≥70 bar, uburhabaxa bomphezulu bunyuke ukusuka kwi-Ra 0.8 µm ukuya kwi-Ra 2.1 µm—kunye nee-microcracks ezingaphantsi komhlaba zivele emva kovavanyo lwe-ultrasonic. I-Monel 400 ye-thermal conductivity ephantsi (21.8 W / m · K kwi-100 ° C) ibamba ukushisa kwindawo yokusika. Obo bushushu buthambisa i-workpiece yendawo, bukhawulezisa ukunxiba kwe-diffusion, kwaye bubangela umsebenzi onzima ngaphambi kwesixhobo-ukwenza ukudlula okulandelayo kube nzima ngakumbi. Siyagunyazisa ngoku emulsions enyibilikayo yeoli (8–10%) ihanjiswa ngeeshaneli zangaphakathi kwi-60-90 bar. Akukho kuqhushumba komoya. Akukho nkungu. Kwaye ungaze ube neoli ethe ngqo-ayinalubricity efunekayo ukucheba i-alloy ngokucocekileyo. Sibeka iliso kwi-pH ngeveki kwaye sitshintshe into yokupholisa rhoqo kwiiveki ezi-4, kungakhathaliseki umthamo osetyenzisiweyo. Isipholisi esingcolisekileyo sibangela umhlwa okhawulezayo ukugrumba kwimigangatho egqityiweyo-ingakumbi kufutshane neengcambu zentambo kunye nee-undercuts.
ULungiselelo kunye neQhinga lokutyisa libaluleke ngaphezu koMmandla wokusonta
Sakhe salahla imizimba yevalve eli-17 kwishifti enye-kungekhona ngenxa yokusilela kwesixhobo, kodwa ngenxa yokuphambuka kwenxalenye. I-Monel 400's high modulus of elasticity (179 GPa) imaski ukungcangcazela, kodwa amandla ayo esivuno atsiba ngama-40% emva nje kwe-5% yomsebenzi obandayo. Ke ukuba umzobo wakho uvumela nokuba yi-0.015 mm intshukumo ngexesha lokurhabaxa, uya kufumana amanqaku encoko amelana nokupholiswa kwaye abeke esichengeni ukutywinwa koxinzelelo. Umgaqo wethu wokulungisa: i-clamp ngaphakathi kwe-1.5 × inxalenye yobubanzi bommandla osikiweyo, sebenzisa iipads zentsimbi eziqinileyo kunye ne-45 ° serrations, kwaye uqinisekise amandla okubamba kunye neeseli zomthwalo-kungekhona i-torque wrenches. Ukutya, siphepha amazinga okutya rhoqo. Endaweni yoko, sinyusa isondlo nge-15% rhoqo nge-2 mm yobunzulu bokusika ngexesha lokurhaxa. Oku kuthintela izikhonkwane zomthwalo ngequbuliso eziqalisa i-BUE okanye ukutsalwa kwesixhobo. Ekugqibeni, sinciphisa ukondla nge-30% kwaye sandise i-RPM kancane-ukugqiba ubuso buphucula i-35%, kwaye i-residual stress iyancipha ngaphantsi kwe-120 MPa (elinganiswa yi-XRD).
Sukutsiba uPhumlo loxinzelelo lwasemva koMatshini-Nokuba “aMalungu alula”
Umthengi wake wala iziseko zempompo ezingama-42 ngenxa yokuba iimvavanyo zokuvuza aziphumelelanga kwiibhari ezingama-220-nangona ephumelele zonke iitshekhi ezilinganayo. Uhlalutyo lwe-Metallurgical lubonise uxinzelelo lwe-tensile yendawo> i-400 MPa kufuphi namachweba agrunjiweyo, okubangelwa ukunyanzeliswa komatshini ongenakunqanyulwa. I-Monel 400 ayiphumli uxinzelelo njengentsimbi ethambileyo. I-lattice yayo ye-FCC ixhathisa ukunyakaza kwe-dislocation, ukuvala kwi-deformation. Siyafaka isicelo ngoku Ukunciphisa uxinzelelo kwi-540-590 ° C ngeeyure ezi-1-2 kwi-vacuum okanye i-hydrogen eyomileyo. kuwo onke amalungu anomlinganiselo > 3:1 okanye iimpawu ezifuna ≤± 0.025 mm GD&T. Sitsiba ukupholisa iziko-sipholisa umoya ukuze sigcine iimpawu zomatshini. Imbuyekezo? I-Zero iphinda isebenze kwiindibano ezibaluleke kakhulu kwiinyanga ezili-18 ezidlulileyo. Kwaye ewe-sibhala yonke imijikelo enezinto ezigawulwa kwiziko elilandelekayo kwimigangatho ye-NIST.
I-Monel 400 machining ayikho malunga namandla akhohlakeleyo. Imalunga nokuchaneka kokucholachola phakathi kwesixhobo, ukupholisa, ukulungiswa, kunye nolawulo lobushushu. Yonke ipharamitha iyasebenzisana. Guqula enye ngaphandle kokulungelelanisa ezinye, kwaye ubomi besixhobo buyawohloka-okanye okubi ngakumbi, inxalenye yengqibelelo iyenzeka. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha umsebenzi ngamnye we-Monel 400 njengenkontileka yesinyithi: kungekhona nje ukusika isinyithi, kodwa ukulondoloza ukwakheka kwayo okuziinkozo okusebenzayo, ukunyaniseka komphezulu, kunye nokuxhathisa ukubola kwexesha elide. Ukuba iprojekthi yakho elandelayo ibandakanya i-monel 400 machining-nokuba yindlu ye-cobalt-alloy nozzle okanye i-non-standard T800-based pump component-qala ngokuqinisekiswa kwezinto eziphathekayo, uqinisekise inkqubo yakho ngokuchasene nedatha yokunxiba yehlabathi, kwaye ungaze ucinge ukuba i-alloy iziphatha njenge-316 engenasici. Ngenxa yokuba kwiindawo ezinoxinzelelo oluphezulu, kwiindawo eziphakamileyo, iingcamango azitywini. Ukuchaneka kwenza.
