ʻOi aku ka ʻoi aku o ka ʻike metala ʻoi aku ka paʻakikī o ka ua ma mua o ka ʻike metallurgical - pono lākou i ka mana hoʻohui ʻia ma luna o ke ʻano waiwai, ke kūpaʻa ʻana, a me ka hilinaʻi hana ma lalo o nā kūlana lawelawe koʻikoʻi. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ua hana mākou ma luna o 12,000 mau mea kikoʻī i loko o nā kila kulika PH-me 17-4PH, 15-5PH, a me nā māka AMS 5659 i hoʻololi ʻia-no nā kino valve hydraulic, nā hale paʻa kiʻekiʻe, a me nā pahu winch ma waho. ʻO ka mea e hoʻokaʻawale ai i kahi hoʻonā kūpono mai kahi hāʻule kumu kūʻai ʻaʻole ʻo ke koho alloy wale nō - ʻo ia ke ʻano o ka hoʻolei ʻana i ka kūpaʻa, ka hoʻomaʻamaʻa ʻana i ka wela, a me ka mīkini multi-axis e hui pū ai i ka pae ʻāpana.
No ke aha i hāʻule ʻole ai ka hana ʻana o ka PH maʻamau ma lalo o nā ukana honua maoli
Ua ʻike mākou i ʻekolu mau ʻano hana hemahema i nā ʻāpana stainless PH i hāʻawi ʻia e nā mea kūʻai aku: microcracking ma hope o ka ʻelemakule, paʻakikī like ʻole ma waena o nā ʻāpana ʻāpana lahilahi, a me ka maʻi ʻaʻai mua ʻana i nā pilina wili. ʻAʻole kēia nā hemahema waiwai - he mau kaʻina hana lākou. No ka laʻana, ua hōʻike ʻia kekahi pāpaʻi ʻEulopa i ka 22% scrap i nā liner cylinder 17-4PH i ka wā ʻelemakule H900 hope loa. Ua hōʻike ʻia kā mākou ʻimi kumu kumu i ka lele ʻana o ka ea umu ahi ʻole i loko o kā lākou umu puʻupuʻu—e kumu ana i ka ± 8°C i nā gradients wela ma waena o ka ukana. Hoʻoponopono mākou iā ia ma ka hoʻololi ʻana i ka ʻelemakule kōkua ʻia me ka palapala ʻāina thermocouple manawa maoli no kēlā me kēia mea hoʻopili. Ka hopena: hāʻule ka ʻokoʻa paʻakikī mai ±12 HRC a i ±3 HRC; Ua hoʻonui ʻia ka hua mai 71% a i 98.4%.
Ua aʻo mai kēlā ʻike iā mākou i kahi haʻawina koʻikoʻi: ʻo ka paʻakikī o ka ua ʻaʻole ia he "hoʻonohonoho-a-poina" mālama wela. He kaʻina hoʻopili paʻa ia - pono e paʻa ka mahana hoʻoheheʻe hoʻonā i loko o ± 5 ° C, pono ka nui o ke kinai ʻana ma mua o 50°C/sec no ka hoʻopau ʻana i ka hoʻokumu delta-ferrite, a ʻo ka manawa o ka wā kahiko / pono e hoʻopili pololei me ka pae precipitate i koho ʻia (e laʻa. E hoʻokaʻawale i 10 mau minuke ma 480 ° C, a kaumaha ʻoe i ka ikaika tensile 15-20% me ka ʻike ʻole ʻia.
Pehea e hoʻoponopono ai ka hoʻohui ʻia ʻana i ka pilikia paʻa ʻole o ke kila kila PH
ʻO ka hapa nui o nā mea hoʻolako i waho i ka hoʻolei ʻana, ka mālama ʻana i ka wela, a me ka mīkini - kēlā me kēia ʻanuʻu e hoʻohui i nā haʻi traceability a me ka hoʻoheheʻe ʻana. Hana mākou i nā mea ʻekolu i loko o ka hale, ma lalo o hoʻokahi ISO 9001: 2015-hōʻoia hale ma Qingdao. I ka wā e pono ai ka mea kūʻai ʻaila ʻAmelika ʻAmelika ʻAmelika 15-5PH piston rod blanks me ≤0.02mm cylindricity ma luna o 450mm lōʻihi, ua hoʻohana kā mākou hui hoʻoheheʻe one i nā mold ZrO₂-hoʻopaʻa ʻia no ka hoʻokō ʻana i ka ʻili o ka ʻili o Ra 3.2μm-ʻoki ʻia ma hope o ka mīkini ʻoki ʻana ma 40%. A laila ua hoʻohana ko mākou kikowaena CNC i nā ala ʻāwīwī adaptive i uku ʻia no nā ʻano hoʻohaʻahaʻa kūloko i ʻike ʻia ma ka scan CMM pre-machining. ʻO ka mea hope loa, ʻo kā mākou keena mālama wela i hoʻopaʻa ʻia i kēlā me kēia ʻāpana me ka hoʻopaʻa inoa thermocouple hoʻokahi - hiki ke ʻike ʻia i ka helu wela kumu a me ka ID pōʻai kapuahi.
ʻAʻole kēia ka hoʻohui ʻana i ka manaʻo. ʻO ka mana hiki ke ana ʻia:
- Hiki ke loaʻa ka waiwai mai ka palapala ingot a hiki i ka hōʻike ʻāpana
- Hoʻopaʻa ʻia ka hoʻoheheʻe nui ʻana i ≤0.015mm ma nā ʻāpana 100-hapa
- Ua hōʻemi ʻia ka ʻokoʻa maʻamau o ka ʻelemakule mai 4.7 HRC a i 1.3 HRC
- Mālama ʻia ka pau ʻana o ka ʻili ma Ra 0.4μm ma nā maka hoʻopaʻa koʻikoʻi
Kahi e hui ai ka PH Stainless Steel i ka hana koʻikoʻi o ka Misiona
ʻAʻole kūʻai nā mea kūʻai i ke kila kila ʻole PH-kūʻai lākou i ka hoʻopaʻa ʻana i ke kaomi ʻole leak-leak, pane pane ʻole-stick valve, a i ʻole ke ola lāʻau kūpaʻa luhi. ʻO ia ke kumu e hoʻokomo ai mākou i ka hōʻoia hana i kēlā me kēia kauoha. No ka AMS 5387 cobalt-alloy nozzle i hui pū ʻia me 17-4PH mounting flange, ʻaʻole mākou e hōʻoia i ka kemika a me ka ikaika tensile. Holo mākou i 500-cycle thermal cycling ma waena o –40°C a me +180°C, a laila e nānā no ka interfacial microseparation me ka ultrasonic C-scan. Hoʻāʻo mākou i ka palahalaha o ka maka sila ma lalo o ka haʻawe hana hoʻohālikelike - ʻaʻole wale ma ka wela ambient. A no nā wili pahu waena winch, hōʻoia mākou i ka ʻoʻoleʻa torsional e pili ana i nā profile torque ikaika i hoʻopaʻa ʻia mai nā ʻāpana kahua maoli.
Hoʻololi kēia lens hana i nā mea a pau. Ua noi aku kekahi mea kūʻai i ka "maʻamau 17-4PH" no kahi pahu hoʻokaʻawale i lalo o ka moana. Ua hōʻike ʻia kā mākou loiloi ʻenekinia ʻaʻole e ola ka huhū H1025 i ʻōlelo ʻia i ka piʻo ʻana i ka 3,000 mika hohonu o ka wai. Manaʻo mākou i hoʻololi ʻia i ka pōʻaiapuni ʻelua makahiki (1025°F × 4h → air cool → 900°F × 4h) i hoʻonui i ka paʻakikī o ka haʻihaʻi e 37% ʻoiai ke paʻa nei ʻo >1,200 MPa UTS. Ua ʻae lākou i ka hoʻololi—a hoʻonui i ko lākou manawa mālama mai 18 a 36 mau mahina.
Ke koho ʻana i kāu hoa hana paʻakikī paʻakikī o ka ua
Inā pili kāu noi i ke kaʻa paikikala, ʻike i ka wai paʻakai, a i ʻole ka ʻaʻahu ʻana, ʻo ke kila kila PH paha kāu koho ikaika loa-akā inā e hoʻomalu kāu hoa hana i ke kaulahao piha. E nīnau i kēia mau nīnau ma mua o ke kau inoa ʻana i kahi PO:
- Hiki iā ʻoe ke hōʻike mai iaʻu i nā pepa lāʻau lapaʻau wela no ʻekolu mau ʻāpana hou o 17-4PH, me nā kūlana thermocouple a me nā helu ramp?
- Hana ʻoe i ka hōʻoia CMM i loko o ka hana ma hope o ka hoʻopaʻa ʻana—a hoʻoponopono i nā ala hana e like me ia?
- He aha kāu ʻokoʻa ʻoi loa o ka paʻakikī ma waena o ka hoʻolei ʻana he 15-5PH hoʻokahi me ke kaumaha >80 kg?
- Pehea ʻoe e hōʻoia ai i ka pale ʻana i ka corrosion no nā hui kuhili PH welded?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. pane i kēlā mau nīnau me ka ʻikepili—ʻaʻole nā palapala. Hoʻopuka mākou i nā hōʻike hoʻokō metala i kēlā me kēia makahiki no nā ʻohana stainless PH ma kā mākou puka ʻenehana. Hāʻawi mākou i nā holo kaʻina hana hui no ka ʻae ʻana i ka ʻatikala mua.
