Xa iinjineli zicacisa i-silica sol investment casting for precision parts of metal, abakhethi nje inkqubo-bakhetha isiqinisekiso sokuzinza kwe-dimensional, ukunyaniseka komphezulu, kunye nokuhambelana kwe-metallurgical phantsi kweemeko zenkonzo ezigqithisileyo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphose ngaphezulu kwe-12,000 yamanani amacandelo awodwa sisebenzisa i-silica sol-ininzi kwi-cobalt-nickel alloys njenge-AMS 5387 kunye ne-T800-apho ukunyamezela kwe-± 0.05 mm akuyonjongo; sisiseko.
Kutheni i-silica sol-hayi iglasi yamanzi okanye udaka-izisa ukuchaneka okuphindaphindiweyo
Abathengi abaninzi bacinga ukuba "ukuphosa utyalo-mali" yindlela enye. Ayiyo. Inkqubo yokubopha ichaza imida yokusebenza. I-silica sol isebenzisa i-colloidal silica (i-SiO₂ nanoparticles emisiwe emanzini) njenge-binder ephambili. I-viscosity yayo ephantsi ingena kwiinkcukacha ezintle; irefractoriness yayo ephezulu imelana ne-1,550°C ubushushu bokugalela kwi-superalloys. Iinkqubo zeglasi zamanzi ziyaqhekeka phantsi kokutshatyalaliswa kwe-thermal. I-Plaster molds iyancipha ngaphezu kwe-600 ° C-ichitha i-microstructure kwi-cobalt-based pump housings.
Siye sabona abathengi betshintsha ukusuka kwiglasi yamanzi ukuya kwi-silica sol emva kweebhetshi ezintathu ezilandelelanayo ezingaphumelelanga kuvavanyo loxinzelelo kwi-420 bar. Unobangela weengcambu? IMicrocracks kudonga lweqokobhe, ayibonakali ngokubonakalayo kodwa iqinisekiswa yi-SEM fractography. Amaqokobhe e-silica sol awabonisi ziphoso ezinjalo-kwanakwi-0.3 mm-thick vanes kwiiassembly zemilomo ye-turbine. Yiyo loo nto i-silica sol yethu yotyalo-mali ibambe isiqinisekiso se-ISO 9001:2015 esinokulandeleka ngokupheleleyo ukuya kutsho kwindawo yobushushu, ubungakanani bamasuntswana obudaka, kunye nokulawula indawo yombethe ngexesha lokomisa.
Udibaniso oluthe nkqo aluthengisi-yindlela esibamba ngayo ± 0.03 mm kwii-300-mm zezindlu zesilinda
Abanye ababoneleli bangaphandle benza iqokobhe, ukuphosa, kunye nomatshini. Senza zontathu kwiziko elinye elithobela i-ISO eQingdao. Kutheni ibalulekile nje loo nto? Ngenxa yokuba indlu yesilinda yempompo yepiston ifuna ukuthelekisa ukwanda kwe-thermal phakathi kweqokobhe, ialloy, kunye ne-CNC fixture. Xa ukuphosa kunye nomatshini kwenzeka phantsi kophahla olunye, silinganisa i-CMM probes ngokuchasene nomphezulu wedatum-hayi iimodeli ze-CAD zethiyori. Silinganisa i-shrinkage vectors kwi-alloy batch nganye, emva koko silungise iindlela zesixhobo ngaphambi kokusika.
Umzekelo: i-AMS 5387 cobalt alloy iyancipha i-1.82% ngokulandelelana kwi-silica sol molds-kodwa kuphela xa indawo yombethe ihlala ngaphantsi -25 ° C ngexesha lokumisa kokugqibela. Siloga yonke imijikelo yokumisa. Ukuba ukufuma kuyanyuka, silahla iqokobhe kwakhona. Akukho ngaphandle. Olo qeqesho lusivumela ukuba sibambe ii-callouts ze-GD&T njengesikhundla ⊕ 0.05 mm MMC kwimingxuma yokuxhoma esibhozo elinganayo-ngaphandle kokugaya okwesibini.
Ukuqinisekiswa kwehlabathi lokwenyani-hayi inkcazo yelebhu-kuqhuba imathiriyeli kunye nokhetho lwenkqubo
Abathengi bayabuza: "Ngaba ungayiphosa i-T800 ialloy kwi-non-standard winch shaft roller?" Ewe-kodwa kuphela ukuba siqinisekisa uyilo lokungena kuqala. I-T800 iqina kunye nokwahlula okubukhali kwe-dendritic. Isango elingabekwanga kakuhle libangela i-porosity ye-centerline kwi-75-mm ububanzi begxalaba. Sisebenzisa ukulinganisa ukuqinisa (usebenzisa i-MAGMASOFT®), emva koko siqinisekise nge-X-ray ye-CT scans kwiilingo ezintathu zovavanyo. Kuphela kungoko sivuma ipateni.
Kulapho amava ahlula khona ithiyori kunikezelo. Siphose imilomo yengxubevange yecobalt kwiimpompo zenaliti ye-subsea esebenza kwi-120 ° C kunye ne-350 bar. Ukungaphumeleli kuthetha ixesha lokuphumla le-$2M. Ngoko ke sivavanya yonke ibhetshi: amandla okuqina ≥1,050 MPa, elongation ≥8%, kunye ne-intergranular corrosion resistance per ASTM G28A. Akukho siqinisekiso ngaphandle kwedatha yovavanyo. Akukho kuthunyelwa ngaphandle kwengxelo yokuhlola esayiniweyo.
Yintoni omele uyilindele xa usebenzisana ne-silica sol investment casting factory
Ukuba indawo yakho ineendonga ezincinci (<2 mm), iipaseji zangaphakathi eziyinkimbinkimbi, okanye zifuna i-Rz ≤ 1.6 µm njenge-cast surface finish-udinga i-silica sol. Kodwa impumelelo ixhomekeke kwintsebenziswano, hayi nje amandla. Kwi-QINGDAO QIANGSENYUAN, uphononongo lobunjineli luqala ngaphambi kokucaphula: sifaka iflegi yee-engile zokuyila phantsi kwe-0.5 °, sicebisa i-radii yokuphumla koxinzelelo, kwaye siqinisekise ukuba into inokuphoswa-okanye kufuneka yenziwe ngomatshini emva kokugalelwa.
Asithengisi iicastings. Sihambisa amacandelo asebenzayo: iivalvu zoxinzelelo ezivale kwibhari engama-450, iziseko zempompo ezithomalalisa ukungcangcazela kwe-3,200 rpm, iirola ze-winch shaft ezisinda kwimijikelo eli-10⁶ kumoya ogcwele ityuwa. Yonke iodolo ibandakanya ii-certs eziphathekayo, iingxelo ze-CMM, kunye neelogi zokunyanga ukushisa. Ixesha lokukhokhela? Iiveki ezili-14 zenqaku lokuqala, iiveki ezi-8 zokuphinda-ziqinisekisiwe. Ayithenjiswanga. Iqinisekisiwe.
Ukujonga phambili, i-silica sol yethu yotyalo-mali yotyalo-mali yandisa umgca wayo wenkqubo ye-hybrid-ukudibanisa i-net-shape ye-casting kunye ne-multi-axis milling kwi-setup enye. Oko kuphelisa iimpazamo zokulungiswa kwakhona kwaye kunqumle ixesha lomjikelo lilonke ngama-37% kumalungu afana neebhloko zehydraulic manifold. Ukuchaneka akumi ndawonye. Nathi asinjalo.
