Woyang'anira zogula ku Sunrise Mining ku Peru adapereka RFP ya Q4 2024 ya ma bucket point 1,200 V51TL Esco Super V series for excavator PC800LC-8 omwe amagwira ntchito mumigodi ya mkuwa, ndipo RFP idatchula "kuyika ndalama mu sera yotayika yokha, kulolerana kwa ISO 8062-3 CT6 dimensional, kuyika mchenga kapena kupanga, kusintha kwa OEM kwa Esco V51TL." Gulu la mainjiniya a Join Machinery lidapereka njira ziwiri zoyikamo (kuyika wotayika V51TL Join Machinery vs kuyika mchenga V51TL yapakhomo), ndipo gulu logula lidayesa anthu awiriwa kudzera mu mayeso amunda a masiku 60 ndi mano 60 pa gulu lililonse. Patatha masiku 60: gulu la sera lotayika linapereka kulekerera kwa ± 0.3 mm (CT6), kukhwima kwa pamwamba pa Ra 6.3 μm, moyo wa kutopa wa ma cycle 6,200, ndi 0.5% shrinkage porosity, pomwe gulu lopangidwa ndi mchenga linapereka kulekerera kwa ± 1.5 mm (CT11), kukhwima kwa pamwamba pa Ra 25 μm, moyo wa kutopa wa ma cycle 2,800, zolakwika 5 pamwamba (8.3% defect rate), ndi dzino limodzi losweka kuchokera ku mchenga. Gulu la sera lotayika linapambana mayeso onse 5 a migodi (kulekerera + pamwamba + kutopa + defect rate + ndalama zonse pa ola limodzi). Ili ndi mayeso a mgodi wa mkuwa wa masiku 2 × 60 omwe amalimbitsa kuponyera kwa sera lotayika ngati njira yayikulu yogulira 70% ya zida za GET ku Europe ndi North America.

Chisankho cha kuponya ndi kuponya mchenga chomwe chatayika ndi chisankho chimodzi chofunikira kwambiri pa njira yogulira zida za GET, ndipo kusankha njira yoponyera kumakhudza miyezo 5 yotsika: (1) kulolerana kwa magawo pa ISO 8062-3 (CT6 vs CT11 = kusiyana kwa kulolerana kwa 5x), (2) kuuma kwa pamwamba pa ISO 1302 (Ra 6.3 vs 25 μm = kusiyana kwa kusalala kwa 4x), (3) moyo wotopa pansi pa kukweza kwa cyclic (6,200 vs 2,800 cycles = kusiyana kwa moyo wa 2.2x), (4) chiŵerengero cha chilema pa kutumiza (0.5% vs 8% = kusiyana kwa chiŵerengero cha chilema cha 16x), ndi (5) mtengo wonse pa ola limodzi logwira ntchito ($0.84 vs $0.93 = 10% TCO kuchepetsa ngakhale mtengo woyambirira ndi wokwera ndi 60-90%. Ziyeso zisanu pamodzi zimatsimikiza mtengo wogulira mano a chidebe pa chidutswa chilichonse, ndipo ziyeso zisanu ndizo maziko a matrix a 5 dimensional procurement matrix (coarse / fine / thin-wall / thick-wall / complex-shape). Gulu la mainjiniya a Join Machinery lathandizira ma RFP 32 aku Europe ndi North America ogulitsa migodi pazaka 16+ zapitazi zaukadaulo wotumiza ziwalo za GET kunja, ndipo ma RFP 32 atsimikizira kuponyedwa kwa sera ngati njira yokhazikika yogulira 70% ya zida za GET zapamwamba kwambiri.

Kuponya kwa sera yotayika poyerekeza ndi kuponya mchenga — kuyerekeza koyambira kwa njira zisanu

Njira yopangira sera yotayika (yomwe imatchedwanso kuponya molondola kapena kuponya ndalama) imaphatikizapo njira 5 zotsatizana kuti apange dzino la chidebe: (1) kulowetsa sera pa 70-80°C mu chidebe chosungunuka cha aluminiyamu kuti chipange mawonekedwe a dzino la chidebe; (2) kusonkhanitsa chitsanzo cha sera polumikiza mapangidwe angapo a sera ku sprue ya sera yapakati kuti ipange mtengo; (3) kumanga chipolopolo cha ceramic poviika mtengo wa sera mu ceramic slurry + stucco coating kwa zigawo 6-8 kwa maola 24-48 kuti apange chipolopolo cha ceramic cha 8-12 mm; (4) kutenthetsa chipolopolo cha ceramic mu autoclave pa 150°C kuti chisungunuke sera yonse, ndikusiya nkhungu yopanda kanthu ya ceramic; (5) kutsanulira chitsulo chosungunuka pa 1,550-1,650°C alloy steel mu chipolopolo cha ceramic chotenthedwa kale, kutsatiridwa ndi kuziziritsa ndi kuchotsa chipolopolo. Njira ya masitepe 5 imapanga dzino la chidebe lokhala ndi kulolerana kwa CT6 ndi Ra 6.3 μm pamwamba.

Njira yopangira mchenga imaphatikizapo njira zisanu zotsatizana zopangira dzino la chidebe: (1) kupanga mapangidwe pamtengo wotsika mtengo wamatabwa kapena pulasitiki; (2) kupanga nkhungu ya mchenga poyika mchenga wa silika wolumikizidwa ndi dongo mozungulira kapangidwe kake mu botolo; (3) kuchotsa mapangidwe mwa kulekanitsa botolo ndikuchotsa kapangidwe kake kuti musiye dzenje la mchenga; (4) kutsanulira chitsulo chosungunuka pa 1,400-1,500°C mu nkhungu ya mchenga, kutsatiridwa ndi kuziziritsa; (5) kuswa nkhungu ya mchenga pogwedeza chopangira kuti muchotse nkhungu ya mchenga, ndikusiya chopangira mano cha chidebe cholimba. Njira ya masitepe 5 imapanga dzino la chidebe lokhala ndi kulolerana kwa CT11 ndi kukhwima kwa pamwamba pa Ra 25 μm.

Gome la magawo 6 likuwonetsa kuti V51TL yotayika ndiyo njira yokhazikika yofotokozera, ndipo tebulo la magawo 6 ndilo maziko a zokambirana za mgwirizano wogula migodi. Gome la magawo 6 ndilo maziko a yankho la RFP la gulu logulitsa la Join Machinery, ndipo tebulo la magawo 6 limatchulidwa ndi gulu logula migodi panthawi yosankha ogulitsa. Gome la magawo 6 likuwonetsanso mphamvu yokambirana m'minda 6 yogula, ndipo mphamvu yokambirana ya magawo 6 ndiyo maziko a mgwirizano wa OEM.

Kutengera kwaukadaulo — kuponyera sera yotayika ndiyo njira yofunika kwambiri yogulira 70% ya zida za GET ku Europe ndi North America

Phunziro lofunika kwambiri kuchokera ku ma RFP 32 a migodi ku Europe ndi North America omwe gulu la mainjiniya a Join Machinery lathandizira pazaka 16+ zapitazi zaukadaulo wotumiza ziwalo za GET ndikuti kuponya sera yotayika ndiye njira yofunikira kwambiri pa 70% ya kugula zigawo za GET ku Europe ndi North America. Njira yoponyera sera yotayika imapereka mulingo woyenera kwambiri pazoyesa zisanu zogula: kulolerana kwa miyeso pa CT6 ± 0.3 mm pa ISO 8062-3, kukhwima kwa pamwamba pa Ra 6.3 μm pa ISO 1302, moyo wotopa pa ma cycle 6,200 pa ISO 1099, chiwopsezo cha chilema pa 0.5% pa kutumiza, ndi mtengo wonse pa ola limodzi logwirira ntchito pa $0.84. Zoyesa zisanu pamodzi zimapangitsa kuponya sera yotayika kukhala chisankho chosasinthika cha 70% ya kugula migodi ku Europe ndi North America kuphatikiza Sunrise Mining (Peru), Glencoe Quarry (Scotland), ndi Bardon Hill Quarry (UK).
