Umphathi wokuthengwa kwempahla weSunrise Mining ePeru ukhuphe i-RFP yekota yesi-4 ka-2024 yeebhakethi zebhakethi ze-V51TL Esco Super V eziyi-1,200 ze-excavator PC800LC-8 esebenza kwimigodi ye-copper ore, kwaye i-RFP ichaze "ukutyalwa kwe-lost-wax kuphela, ukunyamezelana kwe-ISO 8062-3 CT6, ukungabikho kwesanti okanye ukubumba, ukutshintshwa kwe-OEM ye-Esco V51TL." Iqela lobunjineli be-Join Machinery licebise iinkqubo ezimbini zokubumba (i-lost-wax V51TL Join Machinery vs i-sand-cast V51TL yasekhaya), kwaye iqela lokuthenga livavanye abaviwa aba-2 ngovavanyo lwasentsimini lweentsuku ezingama-60 ngamazinyo angama-60 ngebhetshi nganye. Emva kweentsuku ezingama-60: ibhetshi ye-lost-wax inikezele ngokunyamezelana okulinganayo okungu-± 0.3 mm (CT6), uburhabaxa bomphezulu ongu-Ra 6.3 μm, ubomi bokudinwa obuyimijikelo engama-6,200, kunye ne-0.5% shrinkage porosity, ngelixa ibhetshi yesanti-cast inikezele ngokunyamezelana okulinganayo okungu-± 1.5 mm (CT11), uburhabaxa bomphezulu ongu-Ra 25 μm, ubomi bokudinwa obuyimijikelo engama-2,800, iziphene zomphezulu ezi-5 (izinga lesiphene elingu-8.3%), kunye nelizinyo eli-1 elaphukileyo ngenxa yokufakwa kwesanti. Ibhetshi ye-lost-wax iphumelele uvavanyo kuzo zonke iindlela ezi-5 zokwemba (ukunyamezelana + umphezulu + ukudinwa + izinga lesiphene + ixabiso lilonke ngeyure). Le yimeko yovavanyo lomgodi wobhedu oluyi-2-batch × 60-day oluqinisa ukuphoswa kwe-lost-wax njengenkqubo ephambili kwi-70% yokuthengwa kweendawo ze-GET zaseYurophu naseMntla Melika.

Isigqibo sokuphosa utyalo-mali olulahlekileyo ngokuchasene nokuphosa isanti sesona sigqibo sibalulekileyo kwinkqubo yokuthenga iindawo ze-GET, kwaye ukhetho lwenkqubo yokuphosa luchaphazela iimetrikhi ezi-5 ezisezantsi: (1) ukunyamezelana okulinganayo ngokwe-ISO 8062-3 nganye (CT6 vs CT11 = umahluko wokunyamezelana ongama-5x), (2) uburhabaxa bomphezulu ngokwe-ISO 1302 nganye (Ra 6.3 vs 25 μm = umahluko wobushelevu obungama-4x), (3) ubomi bokudinwa phantsi komthwalo ojikelezayo (imijikelo engama-6,200 vs 2,800 = umahluko wobomi obungama-2.2x), (4) izinga lesiphene ngokuthunyelwa ngakunye (0.5% vs 8% = umahluko wezinga lesiphene eli-16x), kunye (5) iindleko zizonke ngeyure nganye yokusebenza ($0.84 vs $0.93 = 10% ukunciphisa i-TCO nangona ixabiso lokuqala liphezulu ngama-60-90%. Iimetrikhi ezi-5 xa zizonke zimisela ixabiso lokuthengwa kwamazinyo ebhakethi ngeqhekeza ngalinye, kwaye iimetrikhi ezi-5 zisisiseko se-5 dimensional procurement matrix (ecoarse / fine / thin-wall / thick-wall / complex-shape). Iqela lobunjineli beJoin Machinery lixhase ii-RFP ezingama-32 zokuthengwa kwemigodi yaseYurophu naseMntla Melika kwiminyaka eli-16+ edlulileyo yamava okuthumela ngaphandle iinxalenye ze-GET, kwaye ii-RFP ezingama-32 ziqinisekisile i-lost-wax casting njenge-Join Machinery default kwi-70% yokuthengwa kweenxalenye ze-GET eziphezulu.

Uluhlu lokuhlola i-RFP lokuthengwa kwemigodi oluneendawo ezi-6 — inkqubo / ukunyamezelana / Ubunzima / ukudinwa / isiqinisekiso / ixesha lokunika

I-RFP yezinyo lebhakethi yemigodi idla ngokuquka amasimi ama-6 okuthenga: (1) iinkcukacha zenkqubo yokuphosa (i-wax elahlekileyo kuphela), (2) ukunyamezelana kobukhulu ngokwe-ISO 8062-3 (umgangatho we-CT6), (3) uburhabaxa bomphezulu ngokwe-ISO 1302 (umgangatho we-Ra 6.3 μm), (4) ubomi bokudinwa ngokwe-ISO 1099 (≥ imijikelo engama-6,000), (5) isatifikethi sezinto (intsimbi ye-alloy + irekhodi yonyango lobushushu), (6) ixesha lokukhokela (iintsuku zokusebenza). Amasimi ama-6 okuthenga kunye amisela impendulo ye-RFP yokuthenga kwemigodi, kwaye amasimi ama-6 asisiseko sengxoxo yesivumelwano se-OEM yoMatshini. Amasimi ama-6 okuthenga adla ngokuchazwa kwitemplate ye-RFP yokuthenga kwemigodi, kwaye amasimi ama-6 ayindlela eqhelekileyo yokujonga umjikelo wokuthenga we-GET parts.

Itheyibhile yoluhlu lokuthengwa kwempahla enamabala amathandathu engezantsi ibonisa amabala okuthengwa kwempahla amathandathu kunye namaxabiso aqhelekileyo amathandathu ahambelanayo e-Join Machinery lost-wax V51TL bucket tooth.

Ubunjineli obuthathwayo — ukwenziwa kwe-lost-wax casting yinkqubo ephambili kwi-70% yokuthengwa kwezixhobo ze-GET zaseYurophu naseMntla Melika

Isifundo esibaluleke kakhulu kwi-RFPs ezingama-32 zokuthengwa kwemigodi yaseYurophu naseMntla Melika ezixhaswe liqela lobunjineli beJoin Machinery kwiminyaka eli-16+ edlulileyo yamava okuthumela ngaphandle kwe-GET kukuba ukuphoswa kwe-wax elahlekileyo yinkqubo ebalaseleyo kwi-70% yokuthengwa kwemigodi yaseYurophu naseMntla Melika. Inkqubo yokuphoswa kwe-wax elahlekileyo inika ibhalansi efanelekileyo kuzo zonke iimetrikhi ezi-5 zokugqiba ukuthenga: ukunyamezelana kobukhulu kwi-CT6 ± 0.3 mm nge-ISO 8062-3 nganye, uburhabaxa bomphezulu kwi-Ra 6.3 μm nge-ISO 1302 nganye, ubomi bokudinwa kwimijikelo engama-6,200 nge-ISO 1099 nganye, izinga lesiphene kwi-0.5% ngokuthunyelwa ngakunye, kunye neendleko zizonke ngeyure nganye yokusebenza kwi-$0.84. Ezi metriki zi-5 xa zidibene zenza ukuphoswa kwe-wax elahlekileyo kube lukhetho oluzenzekelayo kwi-70% yokuthengwa kwemigodi yaseYurophu naseMntla Melika kuquka iSunrise Mining (Peru), iGlencoe Quarry (Scotland), kunye neBardon Hill Quarry (UK).

Kwimeko yokutshintsha yebhajethi ye-15% (umntu osebenza kancinci/usetyenziso olungabalulekanga), inkcazelo yesanti ekwi-$22-26 ngesiqwenga ngasinye yeyona ndlela ifanelekileyo. Kwimeko ye-OEM echanekileyo ye-10% (ukutshintshwa kweKomatsu K-Max / Caterpillar J-series OEM), inkcazelo yeprimiyamu ye-CT5 elahlekileyo kwi-$44-58 ngesiqwenga ngasinye yeyona ndlela ifanelekileyo. Kwimeko ye-5% yokuchonga okukhethekileyo (iingcebiso ze-ripper / izikhuseli zecala / imilo eyinkimbinkimbi), inkcazelo yeprimiyamu ye-CT5 + Ra 0.8 μm kwi-$55-75 ngesiqwenga ngasinye yeyona ndlela iphezulu. Ukhetho lwe-cast ye-4-tier (i-sand-cast CT11 / i-lost-wax CT6 / i-lost-wax CT5 / i-lost-wax CT5+Ra 0.8) lugubungela i-100% ye-GET parts procurement RFP landscape, kwaye ukhetho lwe-cast ye-4-tier yireferensi eqhelekileyo ye-Join Machinery yempendulo ye-OEM RFP. UXin Jack kunye neqela lobunjineli beJoin Machinery baxhasa amaqela okuthengwa kwemigodi ngengxelo yobukhulu be-ISO 8062-3 CT6 yokuthunyelwa ngakunye, ingxelo yobunzima bomphezulu we-ISO 1302 ngakunye, ingxelo yovavanyo lokudinwa kokuthunyelwa ngakunye, ingxoxo yesivumelwano se-OEM, kunye nokuhanjiswa ngexesha elifanelekileyo lomjikelo wempendulo ye-RFP yebhakethi yemigodi.

Iqela lezempahla ezithengiswayo libuza imibuzo malunga nokuphoswa kwesanti ngamazinyo ebhakede xa kuthelekiswa ne-wax elahlekileyo
