Ke lawe nei ʻo Kina i ka pā kila kila
wehewehe huahana
ʻO nā ʻāpana kila kila he huaʻōlelo maʻamau no nā ʻāpana kila kuhiliʻole a me nā ʻāpana kila kūpaʻa waika. I ka hoʻomaka ʻana o kēia kenekulia, ua hoʻokumu ka hoʻomohala ʻana i nā papa kila kila i kahi kumu waiwai nui a me ka ʻenehana no ka hoʻomohala ʻana i ka ʻoihana hou a me ka holomua ʻepekema a me ka ʻenehana. Nui nā ʻano o nā ʻāpana kila kila me nā ʻano waiwai like ʻole, a ua hoʻokumu mālie ʻo ia i nā ʻāpana nui i ke kaʻina hana. Wahi a ke ʻano o ka hui, ua māhele ʻia i ʻehā mau ʻāpana: austenitic stainless steel plate, Martens stainless steel plate (me ka paʻakikī paʻakikī paʻakikī paʻakikī), ferritic stainless steel plate, a me austenite plus ferrite duplex stainless steel plate.
Hoʻokaʻawale ʻia ka mea hana kemika nui a i ʻole kekahi mau hiʻohiʻona i loko o ka pā kila i loko o ka pā kila kila, chrome nickel stainless steel plate, chrome nickel molybdenum stainless steel plate a me ka haʻahaʻa carbon stainless steel plate, high molybdenum stainless steel plate, high cleanly stainless steel plate. a me na mea like. Wahi a nā hiʻohiʻona hana a me ka hoʻopili ʻana i nā papa kila, ua hoʻokaʻawale ʻia i loko o ka nitric acid resistant stainless steel plates, sulfuric acid resistant stainless steel plates, pitting resistant stainless steel plates, stress corrosion resistant stainless steel plates, high strength stainless steel plates, etc. .
Hoʻokaʻawale ʻia ke ʻano hoʻohālikelike maʻamau e like me nā hiʻohiʻona hoʻolālā o ka pā kila a me ke ʻano kemika o ka pā kila a me ka hui pū ʻana o nā mea ʻelua. ʻO ka mea maʻamau, ua māhele ʻia i loko o ka pā kila kila martensite, ka pā kila kulika ferritic, ka pā kila austenitic, ka pā kila kila duplex a me ka paʻakikī paʻakikī o ka ua, a i ʻole i māhele ʻia i ʻelua mau ʻāpana: chrome stainless steel plate a me nickel stainless steel plate. Hoʻohana nui ʻia nā noi maʻamau: nā mea hoʻololi wela no nā mīkini a me nā mea hana pepa, nā mea hana mīkini, nā mea pena, nā mea hana kiʻiʻoniʻoni, nā pipeline, nā mea waho no nā hale ma nā kahakai, etc.
ʻO ka pā kila kila he ʻili maʻemaʻe, ka plasticity kiʻekiʻe, ka paʻakikī a me ka ikaika mechanical, a kūpaʻa i ka corrosion e nā waikawa, nā kinoea alkaline, nā hopena a me nā media ʻē aʻe. He kila hoʻoheheʻe ʻole ʻia ʻaʻole maʻalahi ia, akā ʻaʻole ia he ʻeleʻele loa.

Nā hiʻohiʻona huahana
ʻO ke kūpaʻa ʻino
Hiki i ka pepa kila kila ke kū i ka ʻino maʻamau e like me ka nichrome 304 paʻa. Hoʻohana nui ʻia i nā noi wela kiʻekiʻe, pono nā noi wela kiʻekiʻe i ka sensitization ikaika o nā mea e pale ai i ka corrosion intergranular ma nā haʻahaʻa haʻahaʻa.
Ke kū'ē kū'ē i ka wela wela
He kiʻekiʻe ka pale ʻana o ka oxidation i nā papa kila kila, akā pili ka nui o ka oxidation e nā mea kūlohelohe e like me ke kaiapuni i hōʻike ʻia a me ka morphology huahana.
Nā waiwai kino
ʻO ka huina hoʻololi wela o ka metala e pili ana i nā kumu ʻē aʻe, me ka hoʻohui i ka conductivity thermal o ka metala. I ka nui o na hihia, ka heluna wela o ke ki'i, ka unahi a me ke kūlana metala. Mālama ke kila kila i ka maʻemaʻe a me ka maʻemaʻe o ka ʻili, no laila ʻoi aku ka maikaʻi o kāna hoʻoili wela ma mua o nā metala ʻē aʻe me ka ʻoi aku o ka wela wela. Hāʻawi ʻo Liaocheng Suntory Stainless Steel i nā kūlana ʻenehana no nā papa kila kila. ʻO nā pā kila kuhili ʻole ikaika loa me ke kūpaʻa ʻino maikaʻi loa, ka hiki ke hoʻoheheʻe ʻia a me ka paʻakikī o ka pūnaewele weld, a me ka hana hoʻoheheʻe maikaʻi ʻana ma nā ʻāpana welded. He kiko'ī, aia ka C: 0.02% a emi mai, N: 0.02% a emi mai paha, Cr: 11% a oi aku a emi iho ma lalo o 17%, a he maʻiʻo kūpono o Si, Mn, P, S, Al, Ni, a hoʻokō i ka 12 ≤ Cr Mo 1.5Si ≤ 17, 1 ≤ Ni 30 (CN) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3Mo ≥ 16.0, 0.006 ≤ CN ≤ 0.030 heated Cr 0.5 ° C ≤ 8. , a laila lawe ʻia ma 1 ° C / s ʻO ka mālama ʻana i ka wela ma luna no ka hoʻoluʻu ʻana. No laila, hiki iā ia ke hana i kahi martensite i loaʻa ka hapa nui o 12% a ʻoi aku paha, kahi ikaika kiʻekiʻe o 730 MPa a ʻoi aku paha, kūpaʻa i ka corrosion, hiki ke kulou i ka hana, a me kahi pepa kila kila ikaika loa i ka weld wela. ʻoʻoleʻa. Ma ka hoʻohana ʻana iā Mo, B, a me nā mea ʻē aʻe, hiki ke hoʻomaikaʻi maikaʻi ʻia ka waiwai hana paʻi o ka ʻāpana welded.
ʻAʻole hiki i ka lapalapa o ka oxygen a me ke kinoea ke ʻoki i ke kila kila no ka mea ʻaʻole maʻalahi ke kila kila.
