Lohe ʻoe iā 'Monel 400' a ʻo ka mea mua i manaʻo ʻia ʻo ia ka wai kai, nā ʻūhā, nā ʻauwai pamu. ʻO ia ka mea e hele ai no ka ʻino wai paʻakai, ʻeā? ʻOiaʻiʻo ia, akā ʻo ia hoʻi kahi e hoʻomaka ai nā manaʻo he nui. Manaʻo ka poʻe no ka mea kaulana, ʻaʻole no ka mea maikaʻi loa. Ua ʻike au i hoʻohana ʻia ma kahi i ʻoi aku ka liʻiliʻi o kahi duplex stainless a hana pū kekahi. ʻO ka nuance maoli me kēia huila ʻaʻole ia wale nō kona haku mele—e pili ana i 67% Ni, 23% Cu—ʻo ia ka hoʻomaopopo ʻana i kahi o kāna hui pū ʻana o ka ikaika, weldability, a me nā waiwai non-magnetic e uku maoli ai i nā bila, a ma kahi o kahi maʻamau pipiʻi.
ʻO ka Papa Foundry Reality
ʻAʻole like ka hoʻolei ʻana iā Monel 400 me ka ninini ʻana i ke kila kalapona. ʻAʻole kokoke. ʻO ka mea mua āu e ʻike ai, ʻo ia ka wela—e ninini ʻia ma kahi mahana haʻahaʻa ma mua o ke kila, akā ʻo ka metala me he mea lā ʻo ia ka 'palapala.' ʻAʻole ia e kahe me ka wikiwiki like. I ka hoʻolei ʻia ʻana o ka pūpū, a mākou e hoʻohana nui ai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY)'O ka ho'opiha pono 'ana me ka pani 'ole o ke anu a i 'ole ka holo 'ana o ka noe e pono ke ho'oponopono i ka 'ōnaehana gating. ʻAʻole hiki iā ʻoe ke kope wale i ka hoʻolālā mai kahi hana 316 stainless. ʻO ke ʻano o ka nickel kiʻekiʻe o ka alloy he mea maʻalahi ia i ka absorption kinoea, no laila he koʻikoʻi ke ʻano o ka lewa a me ka hana deoxidation. He liʻiliʻi liʻiliʻi a loaʻa iā ʻoe nā hoʻoheheʻe porous e hele i kahi ʻike akā hāʻule ma lalo o ke kaomi.
A laila ʻo ka hānai ʻana. He mea nui ka hoʻohaʻahaʻa solidification. Ua aʻo mua mākou ʻo ka hoʻohana ʻana i ka nui riser like me ka hoʻoheheʻe ʻana i ke kila kalapona i hoʻohālikelike ʻia he mea ʻai no nā lua shrinkage ma nā ʻāpana mānoanoa. ʻO ka ʻoki ʻana i nā ʻāpana ʻōpala e ʻike i nā hakahaka o loko, e kāʻei i nā ana riser kūpono a me ke kau ʻana. ʻO kēia ʻano lima lima, kokoke i ka ʻikepili hoʻāʻo-a-hewa ʻaʻole ʻoe e loaʻa mai kahi pepa kikoʻī. ʻO nā makahiki he 30 a me ka hoʻolei ʻana ma QSY ʻo ia hoʻi, ua kūkulu mākou i kahi waihona o kēia mau ʻāpana no nā geometries like ʻole, ʻo ia wale nō ke ala e hōʻoiaʻiʻo ai i ke kani mau.
Ma hope o ka hoʻolei ʻana, kūpaʻa ka ʻili. Hoʻokumu ʻia kahi papa ʻeleʻele adherent. ʻAʻole hiki iā ʻoe ke puhi wale me ka pana maʻamau; pono ia i ka hoʻoheheʻe ʻana i ka ʻeleʻele a i ʻole i kekahi manawa he ʻakika ʻakika e hōʻike i ke ʻano o ka ʻili keʻokeʻo ʻeleʻele o ka metala kani. ʻO ka nalo ʻana i kēia kaʻina ma mua o ka hana ʻana e alakaʻi i ka ʻaʻahu wikiwiki. He wahi kikoʻī liʻiliʻi, akā ʻo ka hoʻokuʻu ʻana e hoʻololi i kahi hana waiwai i mea pohō.
Mīkini: Kahi e hui ai ʻo Theory me ka Bit Tool
Inā manaʻo ʻoe he paʻakikī ka mīkini ʻenehana, e hoʻohaʻahaʻa ʻo Monel 400 iā ʻoe. ʻAʻole ʻo ia ka paʻakikī—ʻo ka hana paʻakikī. Me he mea lā e hakakā ana ka mea. Lawe ʻoe i kahi ʻoki, a paʻakikī koke ka wahi ma hope o ka ʻoki ʻoki. E hele i loko no kahi ala hou me ka hohonu like? E lohe ʻoe i ka ʻōhumu ʻana o ka hāmeʻa, inā ʻaʻole ia e paʻi pololei.
ʻO ka hoʻopunipuni nā mea hana ʻoi, rake maikaʻi, a ʻaʻohe hale. Pono ʻoe e hoʻomau i ka ʻoki ʻana a hohonu hohonu e komo i lalo o ka papa hana paʻakikī mai ka hala mua. Holo mālie mākou ma mua o ke kila, me nā meaʻai kaumaha. ʻAʻole hiki ke kūʻai ʻia ka mea hoʻoluʻu, ʻaʻole no ka hoʻoluʻu wale nō - kōkua ia i ka haki ʻana i ka chip. ʻO nā ʻōpala mai ke kaula a paʻakikī, e like me nā pūnana manu kālā e hiki ke hoʻopaʻa i nā mea āpau inā ʻaʻole mālama ʻia. ʻO ka hoʻohana ʻana i ka mea hoʻoluʻu kiʻekiʻe e wāwahi a hoʻokuʻu i nā chip he hana maʻamau i kā mākou hoʻonohonoho CNC.
ʻO ka wili ʻana a me ka paʻi ʻana i kā lākou luʻi kūikawā. He mea nui ka wili peck no ka hoʻomaʻemaʻe ʻana i nā ʻāpana a pale i ka hopu ʻana. No ka paʻi ʻana, hoʻonui mākou i ka lua ma mua o ka hōʻike ʻana o ka pakuhi maʻamau a hoʻohana i ka premium, uhi ʻia nā kī. ʻOiai, ʻaʻole maʻamau ka haki ʻana o ka paipa ma nā lua hohonu. He mea ʻeha ke kumukūʻai o ka paʻi haki ʻana i kahi ʻāpana Monel kokoke i hoʻopau ʻia—i kekahi manawa ʻoi aku ka maʻalahi o ka ʻoki ʻana i ka ʻāpana ma mua o ka hoʻāʻo ʻana a EDM i ka mea hana haki. Hoʻoikaika ia iā ʻoe e hoʻolālā i ke kaʻina meticulously, e hoʻokau i nā hana pilikia i ka wā mua.
Ka Welding Paradox
Ua wehewehe ʻia ʻo Monel 400 e like me ka weldable, a me ka metallurgically, ʻoiaʻiʻo. Akā 'a'ole hiki ke 'ma'alahi.' ʻO ia ka mea hiki iā ʻoe ke loaʻa i kahi hui kani me ka ʻole preheat a i ʻole ka mālama ʻana i ka wela ma hope o ka weld, ʻo ia ka pōmaikaʻi nui. Akā aia ka diabolo i ka ʻenehana.
ʻO kāna mea keleawe kiʻekiʻe ka mea hana nui ma ʻaneʻi. He kiʻekiʻe ka wela o ke keleawe, no laila e hoʻopau koke ka wela mai ke arc. Hiki i kēia ke alakaʻi i ka nele o ka hui ʻana inā ʻaʻole ʻoe e makaʻala - ʻoi aku ka wikiwiki o ka puddle ma mua o kou manaʻo. Pono ʻoe e mālama i kahi arc paʻa a ʻoi aʻe paha ka amperage ma mua o ka stainless. Akā, hoʻokiʻekiʻe loa ia, a hoʻonui ʻoe i ka pilikia o ka pohā wela, ʻoi aku ka nui ma nā ʻāpana i kāohi ʻia.
ʻO ka koho hoʻopihapiha hoʻopihapiha kahi kāhea hoʻokolokolo ʻē aʻe. Hoʻohana pinepine ʻoe i ka Monel 400 filler (ERNiCu-7). Akā no nā hui like ʻole, e ʻōlelo i ke kila kalapona, hiki paha iā ʻoe ke hele i kahi mea hoʻopiha nickel e like me ENi-1 e hoʻoheheʻe i ka neʻe ʻana o ka hao a pale i kahi ʻāpana brittle. Hoʻomanaʻo wau i kahi hana no ka wai kai kahi i hoʻopaʻa ʻia ai ka flange Monel i kahi paipu kila kalapona. ʻO ka hoʻāʻo mua i hoʻohana i ka Monel filler, a ʻo ka HAZ ma ka ʻaoʻao kila i hoʻomohala i nā micro-cracks ma hope o kekahi mau pōʻai wela. Hoʻololi ʻia i ka ENi-1, hoʻopau ʻia ka pilikia. ʻO kēia mau kikoʻī interstitial ka mea e wehewehe ai i kahi hana kūleʻa.
Ma hope o ka weld, hiki i ke kala o ka oxide ke haʻi nui iā ʻoe. Maikaʻi ka ʻōpala a i ka ʻulaʻula. ʻO ka unahi polū a hinahina paha, ua wela loa ʻoe, a ua hoʻololi paha ʻoe i ke kūpaʻa ʻana o ka ʻino ma kēlā ʻāpana, e koi ana i kahi palapala wili māmā e hoʻomaʻemaʻe ai.
Hoʻopiʻi i nā pilikia a me nā manaʻo kuhihewa
Pono kona kaulana i nā noi kai, akā ʻaʻole ia he superhero honua. Ua ʻike au i kuhikuhi ʻia no ka lawelawe ʻana i ka waika sulfuric pumehana no ka mea ua ʻike kekahi i ka 'corrosion-resistant nickel alloy.' He pōʻino kēlā. He kūʻē maikaʻi ʻole ʻo Monel 400 i nā waikawa oxidizing a me nā paʻakai. I loko o ka sulfuric acid, maikaʻi ia ma lalo o ka deaerated, dilute, nā kūlana haʻahaʻa, akā e hoʻolei i ka ea a i ʻole ka wela, a hiki ke ʻino. No kēlā, ke nānā nei ʻoe iā Hastelloy B a i ʻole C.
ʻO kekahi hiʻohiʻona maʻamau he galvanic corrosion. E hoʻopaʻa i kahi flange Monel 400 nui i kahi paipu kila kila i loko o ka wai kai. ʻOi aku ka hanohano o ka Monel. Lilo ia i ka cathode, a ʻoi aku ka wikiwiki o ka ʻōpala, ka anode. Pono ʻoe i nā gaskets insulating a me nā lima lima. Me he mea lā, akā, i ka wikiwiki e hoʻokumu i kahi ʻōnaehana 'corrosion-resistant', ʻo kēia mau kikoʻī kaʻawale ka mea mua e hana ʻia i ka waiwai, e alakaʻi ana i nā hāʻule mua e hoʻopiʻi ʻia ma ka mea.
A laila aia ke koʻikoʻi corrosion cracking (SCC). I loko o nā kaiapuni kai, kūʻokoʻa ia, ʻo ia ke kumu kūʻai nui. Akā, e hōʻike aku iā ia i nā mahu waika hydrofluoric mākū a i ʻole nā alkalika wela, a lilo ka SCC i mea hoʻoweliweli maoli. Ua hoʻolako mākou i kekahi mau kino valve Monel 400 i kahi mea kanu kemika, a ua hāʻule lākou i loko o hoʻokahi makahiki ma kahi wahi holoi holoi wela. Ua huhū ka mea kūʻai aku, akā ʻo ka pepa kikoʻī a lākou i hilinaʻi ai i hōʻike wale i nā kūleʻa moana. Ua hōʻike ka post-mortem i ka SCC transgranular maʻamau. Ke hoʻololi nei ka hoʻoponopono iā Nickel 200 no kēlā lawelawe kikoʻī. Ua hōʻike ʻia ʻo ka koho ʻana i nā mea waiwai ʻaʻole e pili ana i kahi waiwai hoʻokahi; he ʻōnaehana o nā kūlana lawelawe.
ʻO ka Sourcing a me ka Chain Supply Practical
ʻAʻole like ka loaʻa ʻana o ka waiwai Monel 400, ʻoi aku ka nui ma nā ʻano hoʻolele paʻakikī, e like me ke kauoha ʻana i ka pā 304. ʻO ka hoʻomalu kemika hehee ka mea nui. He pōʻino maʻaneʻi nā ʻano mea e like me ka sulfur a me ke kēpau, i hiki ke ʻae ʻia i kekahi mau kila, e hōʻemi ana i ka wela i ka wā o ka hoʻolei ʻana a i ʻole ka wili. Pono ʻoe i kahi mea hoʻolako nona ka waihona i hōʻoia ʻia me ka nickel-copper alloys.
ʻO kēia kahi e makemake ai kahi hoa QSY hana ʻokoʻa. Me ko mākou nānā ʻana i nā mea hoʻoheheʻe kūikawā, ʻaʻole mākou e ninini wale i nā mea a pau e komo mai ana. Hoʻokumu mākou i ka nickel a me ke keleawe kūlana mua, a kākoʻo ʻia ka hoʻoheheʻe ʻia e ka spectrometry no kēlā me kēia wela. ʻAʻole noʻonoʻo ka pūʻolo hōʻoia; ʻo ia ka hōʻoia o ke kemika e hiki ai i ka ʻāpana ke hana e like me ka mea i manaʻo ʻia. No ka mea hana a i ʻole OEM, he ʻinikua kēia traceability. Hiki iā ʻoe ke ʻike i nā kikoʻī ʻenehana a me nā palapala hōʻoia no kā mākou kaʻina hana ma kā mākou pūnaewele ma https://www.tsingtaocnc.com.
ʻO nā manawa alakaʻi kekahi mea maoli. ʻAʻole ia he hale waihona no ka nui o nā ʻano. No ka pahu pahū maʻamau a i ʻole ke kino valve nui, ke nānā nei ʻoe i kahi pōʻaiapili hana e pili ana i ka hana ʻana i ke ʻano, ka hoʻoheheʻe ʻana, ka ninini ʻana, ka mālama ʻana i ka wela (maʻamau ka hoʻomaha ʻana i ke kaumaha), a me ka NDE nui. ʻO ka holo wikiwiki ʻana e hoʻonui nui i ka pilikia. Ua koi au i nā mea kūʻai aku i ka hoʻouna ʻana i 4 mau pule ma kahi mea hoʻolei one paʻakikī. ʻO ke ala wale nō e paʻi ai, ʻo ia ka loaʻa ʻana o kahi hiʻohiʻona kūpono ma ka papa a hoʻokuʻu i nā ʻanuʻu kūpono kūpono, ʻaʻole mākou e hana. ʻO ka mālama ʻana i kēlā mau manaʻo he ʻāpana o ka hana.
ʻO ke kumukūʻai, ʻoiaʻiʻo, ʻo ke kiaʻi puka hope loa. Hoʻohana ʻoe iā Monel 400 kahi e hōʻoia ai ka nui o ke kumukūʻai ola. ʻAʻole hiki ke koho maʻalahi loa ma ka papa kiʻi. Akā ke helu ʻoe i ke kumukūʻai o ka pani ʻana no ka hoʻololi ʻana i kahi ʻāpana kila kalapona i hoʻoheheʻe ʻia i loko o kahi laina hoʻoluʻu wai kai koʻikoʻi, a i ʻole ka pilikia kaiapuni o ka leak, hoʻololi ka makemakika. ʻAʻole ka waiwai ma ke kumukūʻai paona o ka huila; aia i loko o nā ʻumi makahiki o ka lawelawe uneventful hiki iā ia ke hāʻawi ke hoʻohana pono ʻia.
