ʻO ke apo make ka puʻuwai o kahi wili pellet. ʻO kona ʻano hana a me ka maikaʻi o ka hana ʻana e hoʻoholo pololei i ka maikaʻi o ka pellet, ka hiki ke hana, ka hoʻohana ʻana i ka ikehu, a me ke ana nui o ke kumukūʻai no kēlā me kēia tona. Ke ʻaʻahu mua ʻia kahi apo make, ālai pinepine, a hana paha i nā pellets paʻa ʻole, huli pinepine ke kumu kumu i ke koho ʻana i nā mea a i ʻole nā pōkole hana. Nānā kēia ʻatikala i nā ʻohana ʻelua o nā mea apo make nui martensitic stainless steel (X46Cr13/4Cr13) a me ke kila alloy (20CrMnTi) a me nā kaʻina hana e unuhi i nā waiwai mea i ka hana hana.
No ke aha he mea nui ka mea make apo
I ka wā o ka hana ʻana o ka pellet, hana ka make apo ma lalo o ke kaomi kiʻekiʻe i ka manawa like, ka friction kiʻekiʻe, a me ke kaumaha mechanical cyclic. Hoʻoikaika ʻia ka feed mash ma o nā lua make e nā wili kaomi ʻoiai ʻo ka mahu, ka makū, nā minelala, a me nā mea hoʻopili abrasive e hana mau ana ma ka ʻili hana a me nā paia lua. Hiki i kahi koho mea maikaʻi ʻole ke hoʻoheheʻe ʻia i nā pilikia he nui: ka wikiwiki o ka ʻaʻahu ʻana o ka lua, ka emi ʻana o ke kūpaʻa compression, ka emi ʻana o ka paʻakikī pellet, ka paʻakikī make pinepine, ka helu ʻana o ka ʻili o loko, a me ka pilikia haki kiʻekiʻe [1].
He mea koʻikoʻi nā pilikia waiwai. ʻOi aku ke kumukūʻai o kahi make haʻahaʻa e pono ai ke hoʻololi pinepine ʻia, hoʻonui i ka manawa hana, a hōʻino paha i ka maikaʻi o ka pellet ma ke kumukūʻai holoʻokoʻa o ka loaʻa ʻana ma mua o kahi make premium me ke ola lawelawe lōʻihi.
Nā ʻOhana Mea: He Nānā Hoʻohālikelike
Hoʻohana nui ka ʻoihana make apo i ʻelua mau ʻano mea, me ke koho i hoʻokele ʻia e ka hoʻopili ʻana o ka meaʻai, nā kūlana hana, a me ka pilikia o ka pala.
ʻO ka māhele mua ʻo Martensitic Stainless Steel, me nā papa maʻamau e komo pū ana me X46Cr13 a me 4Cr13, e hoʻokō ana i ka paʻakikī o HRC 52 60. ʻO nā ikaika koʻikoʻi e komo pū ana me ka paʻakikī kiʻekiʻe, ke kūpaʻa i ka pala, a me ke ola lawelawe lōʻihi. ʻO ka palena nui ka uku ʻāpana kiʻekiʻe. ʻO nā noi maʻamau e komo pū me ka moa, ka hānai wai, a me nā ʻano hana kiʻekiʻe.
ʻO ka lua o ka māhele ʻo Alloy Steel, me nā papa maʻamau e pili ana i ka 20CrMnTi, 40Cr, a me 42CrMo, e hoʻokō ana i ka paʻakikī o HRC 55 60. ʻO nā ikaika koʻikoʻi e pili ana i ka paʻakikī maikaʻi, ke kumukūʻai hoʻokele waiwai, a me ka ikaika mechanical maikaʻi loa. ʻO ka palena nui ka haʻahaʻa o ke kūpaʻa ʻana i ka pala. ʻO nā noi maʻamau e pili ana i ka moa, nā holoholona, a me ka biomass maʻamau. Nā kumu: [1], [2].
X46Cr13 / 4Cr13: Ke Kūlana ʻOihana no nā Make Apo Premium
ʻO X46Cr13 (DIN 1.4034, ka inoa Kina 4Cr13) he kila kila martensitic a ʻo ia ka mea i hoʻohana nui ʻia no nā make apo hānai ʻoihana. ʻAʻole ia he mea ulia ka mana akā loaʻa mai kahi kaulike kūpono o nā waiwai.
Paʻakikī. Ma hope o ka mālama ʻana i ka wela vacuum, loaʻa iā X46Cr13 ka HRC 52 60 ma ka ʻili hana me ka mālama ʻana i ka paʻakikī o ke kumu. ʻO ka kikoʻī hana ʻo Shanbao, no ka laʻana, ke kuhikuhi nei iā HRC 52 55, ʻoiai ʻo nā make premium a Hongyang e hoʻokō iā HRC 58 60 ma o ka hoʻopaʻakikī vacuum i hoʻonui ʻia [2], [3].
Ke Kū'ē ʻana i ka ʻAʻai. ʻO ka nui o ka chromium (ma kahi o 13%) e hāʻawi i ka pale ʻoi aku ka maikaʻi i ka makū, ka mahu, a me nā mea hānai ʻino iki ma mua o nā kila hao. No nā ʻano hānai wai me ka nui o ka makū, a i ʻole no nā wili e hana ana i nā aniau haʻahaʻa, hoʻolōʻihi pololei kēia pale ʻana i ka ʻai i ke ola make [1].
Ke Kū'ē ʻAʻahu. ʻO ka hui pū ʻana o ka nui o ke kalapona a me nā carbide chromium i hana ʻia i ka wā o ka mālama wela e hana i kahi ʻili kū'ē i ke kapa e mālama i ke ʻano o ka lua ma luna o nā holo hana lōʻihi. I ka hoʻāʻo hoʻohālikelike, ʻoi aku ka maikaʻi o nā make apo X46Cr13 ma mua o nā make kila alloy i nā noi moa a me nā mea hānai wai kiʻekiʻe [1].
Rula Koho Kūpono. No nā wili hānai kahi i loaʻa ai ke ʻano hāʻule mua ka ʻaʻahu ʻana o ka lua, ka hōʻino ʻana o ka ʻili o loko, a i ʻole ka nalowale o ka mana ma mua o ka palaho kemika, ʻo X46Cr13 ke koho mea ikaika loa a puni. Ua hoʻopaʻa ʻia kahi noiʻi hihia Hongyang Kazakhstan i kahi ola lawelawe make apo o 880 mau hola (mai 600 mau hola ma ka mīkini i pani ʻia) me nā make like X46Cr13, e hōʻike ana i ka hoʻomaikaʻi ʻana o 46.7% [3].
Ke kila hao 20CrMnTi: Ka Lio Hana Hoʻokele Waiwai.
He kila huila carburizing ka 20CrMnTi i hoʻohana nui ʻia no nā make apo i nā manu maʻamau, nā holoholona, a me kekahi mau noi biomass kahi i haʻahaʻa ai ka pilikia o ka pala a ʻo ka lakio kumukūʻai-hana ke kumu nui o ka noʻonoʻo ʻana.
Paʻakikī. Hāʻawi ʻo 20CrMnTi i ka paʻakikī maikaʻi loa, he mea waiwai nui ia i ka wā e holo ai ka wili pellet ma lalo o ke kaumaha loli, i ka wā e loaʻa ai nā ʻāpana coarse i nā formula hānai, a i ʻole i ka wā ʻaʻole hiki ke mālama mau ʻia ka hoʻoponopono ʻana o ka wili ma ka pololei kūpono [1].
Paʻakikī. Ma hope o ka carburizing a me ka quenching, loaʻa iā 20CrMnTi ka HRC 55 60 ma ka ʻili me kahi kumu paʻakikī. Kūʻē kēia hui i ka ʻaʻahu ʻana o ka ʻili me ka omo ʻana i nā ukana hopena e hiki ai ke haki i kahi mea palupalu [2].
ʻIkepili Ola Lawelawe. I ka hana ma ke kahua, hiki i nā make apo 20CrMnTi ke hoʻokō i 2,000-3,000 mau hola ma ka hānai manu maʻamau i hoʻokumu ʻia i ka palaoa a me 1,200-1,800 mau hola ma ka hana ʻana i nā pellet lāʻau paʻakikī me ka abrasion haʻahaʻa. Ma nā mea abrasive kiʻekiʻe e like me ka ʻili laiki (paʻakikī Mohs 7 ma muli o ka nui o ka silica), hiki i ke ola lawelawe ke hāʻule i 800-1,500 mau hola [4].
Nā Palena. ʻO ka nāwaliwali mua ka pale ʻana i ka pala. I nā ʻano hana me ka makū kiʻekiʻe, ka paʻakai, a i ʻole nā mea waikawa, hiki i ka 20CrMnTi ke maʻalahi i ka popo a me ka hoʻouka kemika e hoʻopōʻino i nā ʻili o ka lua make, e hoʻonui ana i ka friction, e hōʻemi ana i ka throughput, a e hoʻopōkole ana i ke ola lawelawe kūpono me ka nānā ʻole i ka hana mechanical wear [1].
Nā Mea Hana ʻAʻole Kūpono no nā Make Apo Feed-Grade ʻOihana
He mea nui e wehewehe i kahi kuhi hewa maʻamau. ʻOiai kekahi mau alakaʻi wili pellet maʻamau e kuhikuhi ana i nā kila bearing (e like me GCr15 / 52100) ma ke ʻano he mau mea make apo, kūpono kēia mau mea no nā make pālahalaha i nā hana biomass liʻiliʻi. Loaʻa iā GCr15 nā ʻano hoʻonui wela like ʻole a nele i ke kūpaʻa corrosion a me ka paʻakikī hopena e pono ai no nā make apo feed-grade ʻoihana e hana ana ma lalo o nā kūlana ʻoihana mau. Pono nā wili pellet hānai ʻoihana e hoʻohana i ke kila kila martensitic X46Cr13/4Cr13 a i ʻole ke kila alloy 20CrMnTi no nā make apo [1].
Ke Kaʻina Hana Hana: Kahi e Hui ai nā Mea me ka Precision
He mea pono ke koho ʻana i nā mea akā ʻaʻole lawa. Hoʻoholo ke kaʻina hana inā unuhi ʻia nā waiwai kumumanaʻo o ka mea i ka hana hana.
Ke hana ʻana. Hoʻomaka ka hana ʻana i ka make apo maikaʻi me ka blank maka. Hoʻohana nā mea hana Premium i nā blanks maʻamau me nā mea maka chromium kiʻekiʻe a me ka paʻakikī blank i kāohi ʻia (HB 180 220). Hoʻomaʻemaʻe ka forging kūpono i ke ʻano o ka palaoa, hoʻopau i nā hakahaka kūloko, a hiki ke hoʻolōʻihi i ke ola make hope loa ma kahi o 15% i hoʻohālikelike ʻia me nā koho ʻē aʻe i hana ʻole ʻia [5].
ʻO ka ʻeli ʻana i ka pū. Hana ʻia nā lua make me ka hoʻohana ʻana i nā mīkini ʻeli pū CNC automated e hana ana i nā wikiwiki a hiki i 15,000 RPM. ʻO ka laumania o ka lua kahi palena koʻikoʻi o ka maikaʻi: ʻoi aku ka paʻakikī o nā lua e hoʻonui i ka friction, hoʻemi i ka throughput, a hoʻolalelale i ka ʻaʻahu. Loaʻa i nā mea hana premium kahi hoʻopau ʻili o Ra 0.4 0.8 μm ma ka paia o loko o ka lua, e hoʻokokoke ana i ka maikaʻi o ka polish aniani [5].
Ka Hana Wela Vacuum. ʻO ka hana wela ka hana koʻikoʻi loa. ʻO ka hoʻopaʻakikī ʻana i ka vacuum e like me nā ʻano hana lewa a i ʻole ka ʻauʻau paʻakai e hoʻokō i ka paʻakikī like me ka ʻole o ka oxidation o ka ʻili a i ʻole ka decarburization. Hoʻolālā ke kaʻina hana i ka HRC 52 60 ma ka ʻili hana me ka mālama ʻana i ka paʻakikī o ke kumu e kūʻē i ka haki ma lalo o ke ʻano ukana cyclic o nā ratios fiber kiʻekiʻe [5], [3].
Hoʻopau CNC. Ma hope o ka mālama wela ʻana, hana ka make i ka hoʻopau CNC, countersinking, a me ka wili ʻana i ka lua o loko. Hana ʻia ka countersinking e nā mīkini countersinking CNC aunoa e hōʻoia i nā ʻano komo lua like, ʻoiai ua wili ʻia ka lua o loko i nā ʻae ʻana o ka dimensional e hōʻoia i ka hakahaka roller-to-die kūlike ma ke anapuni piha [5].
Hōʻoia Kūlana. Hōʻoia nā mea hana premium i ka paʻakikī, ke ahonui o ke anawaena lua (± 0.15 mm no nā make kiʻekiʻe), ka hoʻopau ʻana o ka ʻili, a me ka lakio compression ma mua o ka hoʻouna ʻana. Hoʻohana kekahi mau mea hana i ka laser-etch i ka lakio compression a me ka māka mea ma ke kino make no ka ʻike ʻana o ka mea hoʻohana [3].
Ke koho ʻana i nā mea kūpono: He ʻōnaehana hoʻoholo
ʻO ke ʻano hoʻoholo no ke koho ʻana i nā mea penei. No ka hānai manu a holoholona maʻamau i kahi maloʻo, ua ʻōlelo ʻia ʻo 20CrMnTi ma ke ʻano he koho kūpono i ke kumukūʻai. No ka hānai manu a holoholona paha i nā kūlana makū a loli paha, ua ʻōlelo ʻia ʻo X46Cr13 a i ʻole 4Cr13. No ka hānai wai (iʻa/ʻōpae) me ka makū kiʻekiʻe, ua ʻōlelo ʻia ʻo X46Cr13 a i ʻole 4Cr13. No ka pellet lāʻau me ka pilikia haʻahaʻa o ka palaho, ua ʻōlelo ʻia ʻo 20CrMnTi. No nā ʻano hana abrasive kiʻekiʻe e loaʻa ana nā minelala a silica paha, ua ʻōlelo ʻia ʻo X46Cr13 a i ʻole 4Cr13. No ke ola lawelawe kiʻekiʻe loa, ua ʻōlelo ʻia ʻo X46Cr13 a i ʻole 4Cr13 me ka mālama wela vacuum i HRC 58 60. No nā noi formula maʻamau i kaupalena ʻia i ka waihona kālā, ua ʻōlelo ʻia ʻo 20CrMnTi.
Hopena
ʻO ke koho ʻana i nā mea make apo he hoʻoholo ʻenekinia me nā hopena kālā pololei. ʻO ke kila kila martensitic X46Cr13 me kona paʻakikī kaulike, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa ʻana i ka palaho e hōʻike ana i ke kūlana ʻoihana no nā make apo wili pellet hānai premium. Hāʻawi ke kila alloy 20CrMnTi i kahi koho kūpono no nā noi maʻamau me ka pilikia haʻahaʻa o ka palaho. ʻO ke kaʻina hana ʻana, ʻo ia hoʻi ka mālama wela vacuum a me ka pololei o ka wili pū, he mea koʻikoʻi like ia i ka unuhi ʻana i nā waiwai mea i ka hana hana. No nā wili e ʻimi nei e hōʻemi i ke kumukūʻai no kēlā me kēia tona a hoʻolōʻihi i nā manawa hoʻololi make, ʻo ka hoʻopukapuka kālā ʻana i ka maikaʻi o nā mea a me ka pololei o ka hana ʻana e loaʻa pinepine ai nā hoʻihoʻi e ʻoi aku ka nui ma mua o ke kumukūʻai kūʻai hoʻonui.
