I loko o nā ʻoihana hana mining honua, quarrying, a me ka hana ʻana i nā mea hoʻohuihui, ʻo ke ola lawelawe o nā ʻāpana ʻaʻahu crusher e hoʻoholo pololei i ka pono o ka hana ʻana, ka manawa downtime, a me ka huina kumukūʻai o ka loaʻa ʻana (TCO). I ke koho ʻana i nā ʻāpana ʻaʻahu e like me nā papa ʻauwae, nā liner cone, nā blow bars, a me nā wēlau hāmare, nānā nui ka hapa nui o nā mea hana i ka haku mele ʻana o nā mea, e like me ke kila manganese a i ʻole ka nui o ka chromium, akā nānā ʻole i kahi mea koʻikoʻi e kuhikuhi ana i ka hana hope loa o ka ʻāpana: ka mālama wela. Hōʻike ka ʻikepili metallurgical ʻoihana ʻoiai me nā ʻano kemika like, hiki i ʻelua mau ʻāpana ʻaʻahu ke loaʻa kahi ʻokoʻa 50-100% i ke ola lawelawe, ma muli wale nō o nā ʻokoʻa o nā kaʻina hana mālama wela. No nā mea hana crusher, ʻo ka hoʻomaopopo ʻana i ke kuleana o ka mālama wela ʻaʻole ia he ʻike loea wale nō - he mea hana koʻikoʻi ia e koho i nā ʻāpana ʻaʻahu kiʻekiʻe a pale i nā hemahema mua ʻole. Hoʻokaʻawale kēia ʻatikala i nā kumumanaʻo koʻikoʻi o ka mālama wela no nā ʻāpana ʻaʻahu crusher, nā kaʻina hana maʻamau no nā mea nui, a pehea e hāʻawi ai ka mālama wela i nā pono hana.
No ke aha ʻaʻole hiki ke kūkākūkā ʻia ka mālama ʻana i ka wela no nā ʻāpana Crusher Wear
ʻO nā ʻāpana ʻaʻahu i hoʻolei ʻia, pololei mai ka ʻōmole foundry, he ʻano metallurgical paʻa ʻole, me ka paʻakikī like ʻole, ke kaumaha koena kūloko, a me nā precipitates carbide brittle e kaupalena nui ana i ka hana. ʻO ka mālama wela kahi hana metallurgical i kāohi ʻia e hoʻohana ana i ka hoʻomehana pololei, ka paʻa ʻana, a me nā pōʻaiapuni hoʻoluʻu e hoʻololi i ka microstructure kūloko o ka metala, e wehe ana i ka hiki piha o kāna mau mea alloy. ʻO ka pilikia nui no nā ʻāpana ʻaʻahu crusher āpau ke kaulike ʻana i ʻelua mau waiwai kūʻē: ke kū'ē ʻana i ka abrasion e kū'ē i ka ʻoki ʻana mai ka pōhaku paʻakikī, a me ka paʻakikī e kū'ē i ka haki ma lalo o ka hopena kiʻekiʻe. Me ka ʻole o ka mālama wela kūpono, ʻaʻole hiki ke hoʻokō i kēia kaulike. No ka laʻana, hiki i kahi hoʻolei chromium kiʻekiʻe ke loaʻa ka pale ʻana i ka ʻaʻahu maikaʻi loa, akā me ka ʻole o ka mālama wela i hoʻomaikaʻi ʻia, e brittle loa ia e kū'ē i ka hopena waena, e alakaʻi ana i ka chipping catastrophic a i ʻole ka haki ʻana i waena o ka hana.
Nā Kaʻina Hana Hoʻomehana Maʻamau no nā Mea Hana ʻĀpana Mainstream
Loaʻa i kēlā me kēia mea pale i ke komo ʻana kahi papa hana lapaʻau wela kūikawā, i hana ʻia no kona ʻano kemika a me ka hoʻohana i manaʻo ʻia. No nā hale hana ʻoihana, ʻo ka mālama pono ʻana i kēia mau kaʻina hana ke kumu o nā ʻāpana hana kiʻekiʻe a kūlike.
ʻO ka mea mua, ka hoʻoikaika ʻana i ka wai no ke kila manganese austenitic, ke kūlana gula no nā ʻāpana kuʻi mua. ʻO nā kila manganese, me ka Mn13Cr2 i hoʻohana nui ʻia a me ka Mn18Cr2 paʻakikī kiʻekiʻe, hilinaʻi i kahi microstructure austenitic hoʻokahi-phase e hāʻawi i kā lākou waiwai paʻakikī hana: i ka wā e hōʻike ʻia ai i ka hopena kiʻekiʻe, paʻakikī ka ʻili e kūʻē i ka abrasion, ʻoiai ke kumu e paʻa mau ana e pale i ka haki. Pono ke kaʻina hana hoʻoikaika wai e hoʻomehana i ka hoʻolei ʻana i kahi 1050-1100°C pololei, e paʻa ana i kēia mahana e hoʻoheheʻe i nā carbides i loko o ka matrix, a laila e kinai koke iā ia i ka wai e hoʻopaʻa i ka ʻano austenitic. ʻOiai kahi ʻokoʻa iki, e like me ka lawa ʻole o ka manawa paʻa a i ʻole ka hoʻoluʻu lohi, e hana i nā precipitates carbide e hana, e hōʻemi ana i ka paʻakikī o ka ʻāpana a hiki i ka 70% a e hoʻolilo iā ia i mea maʻalahi i ka haki koke.
ʻO ka lua, ka hoʻopau ʻana a me ka hoʻomaʻamaʻa ʻana no ka hao hoʻolei keʻokeʻo kiʻekiʻe-chromium, kūpono no ka abrasion kiʻekiʻe, ka hopena haʻahaʻa lua a me ke kolu. Loaʻa ka pale ʻana o ka hao kiʻekiʻe-chromium mai kona mau ʻāpana chromium carbide paʻakikī a me ka matrix martensitic. Pili ke kaʻina hana mālama wela i kahi pōʻaiapuni quenching i hoʻomalu pono ʻia e hana i ke ʻano martensitic, a ukali ʻia e kahi hana hoʻomaʻamaʻa e hōʻoluʻolu i ke kaumaha kūloko a hōʻemi i ka austenite paʻa brittle. Hoʻohālikelike kēia kaʻina hana i ka paʻakikī loa no ke kūpaʻa ʻana me ka paʻakikī lawa e pale aku ai i ka chipping, e hāʻawi ana i ke ola lawelawe lōʻihi aʻe i 3x ma mua o ke kila manganese maʻamau i nā noi abrasion kiʻekiʻe.
Nā Pōmaikaʻi Paʻa o ka Hoʻomaʻamaʻa Wela i Hoʻomaikaʻi ʻia
No nā mea hoʻokele crusher, ʻo ka hoʻopukapuka kālā ʻana i nā ʻāpana ʻaʻahu me ka mālama wela i kāohi pono ʻia e hāʻawi i nā loaʻa kālā a me nā hana i hiki ke ana ʻia. Hoʻolōʻihi ia i ke ola lawelawe ma 30-80% i hoʻohālikelike ʻia me nā ʻāpana me ka mālama wela ma lalo o ke kūlana, e hōʻemi ana i ka pinepine o ka hoʻololi a me nā kumukūʻai hana e pili ana. Hoʻopau pū ia i ka downtime i hoʻolālā ʻole ʻia i hoʻokumu ʻia e ka haki koke ʻana o nā ʻāpana, kahi pilikia maʻamau me nā ʻāpana i mālama ʻole ʻia i ka wela e hiki ke uku i nā lua waena he ʻumi tausani kālā i ka hana nalowale i kēlā me kēia hola. ʻO ka hope loa, hoʻemi ia i ka TCO holoʻokoʻa: ʻoiai ʻoi aku ka kiʻekiʻe o ke kumukūʻai mua o nā ʻāpana i mālama ʻia i ka wela kiʻekiʻe, hāʻawi lākou i 2-3x lōʻihi o ke ola lawelawe, e hōʻemi ana i ka hoʻolilo ʻana o nā ʻāpana ʻaʻahu makahiki a hiki i ka 40%.
Ma Shanghai Haocheng Machinery Parts Co., Ltd., ʻike mākou i ka mālama wela ʻana ma ke ʻano he kumu o kā mākou hana hana ʻāpana komo. Ua lako kā mākou hale hana hao me nā umu mālama wela i kāohi ʻia e ka mahana, a hoʻomohala kā mākou hui metallurgical i nā pōʻaiapuni mālama wela i hana ʻia no kēlā me kēia mea a me ka hoʻolālā ʻāpana. Hoʻomaʻamaʻa ʻia kēlā me kēia pūʻulu o kā mākou mau ʻāpana komo i ka hoʻāʻo mālama wela ma hope o ka wela, me ke ana ʻana o ka paʻakikī a me ka nānā ʻana i ka metallographic, e hōʻoia i ka hana kūlike e hoʻokō ai i nā kūlana kuʻi koi loa.
I ka hopena, ʻo ka hoʻonohonoho ʻana o nā mea hana wale nō ke kumu hoʻomaka o kahi ʻāpana ʻaʻahu crusher kiʻekiʻe—ʻo ka mālama wela kūpono ka mea e hoʻololi ai i kahi hoʻolei maikaʻi i ʻāpana hilinaʻi a lōʻihi. Ma ka hoʻokau mua ʻana i ka maikaʻi o ka mālama wela i ke koho ʻana i nā mea hoʻolako ʻāpana ʻaʻahu, hiki i nā mea hana ke wehe i nā loaʻa pono koʻikoʻi a me nā mālama kālā no kā lākou hana wili.
