Hoʻopuka pōkole o ka Heat Resistant Steel Welding Rod no Chromium Molybdenum Steel

Ka hoʻomohala ʻana i ke kila wela ferritic
E hoʻonui i ka Cr-1.25Cr i ka 12Cr
Hoʻohui V, Nb, Mo, W, Co, etc.

ʻO ka ulu ʻana o ka ferritic heat-resistant steel

Nānā:
Wahi a ka hoʻomaʻamaʻa honua, ua kapa ʻia nā mea i kapa ʻia he pearlite, bainite, a me martensitic heat-resistant steels i loko o ka paila a me ka pipeline steels i kapa ʻia ʻo "ferritic heat-resistant steels".

Me ka hoʻololi ʻana o ka hoʻolālā ikehu o koʻu ʻāina a me ka hoʻonui ʻana i ke kūkulu ʻana i ka mana, ʻoi aku ka maikaʻi, ka maʻemaʻe, a me nā ʻāpana nui a me nā ʻāpana kiʻekiʻe. Ma ka hoʻonui ʻana i nā ʻāpana mahu (ka kaomi a me ka mahana), hiki iā ia ke hoʻomaikaʻi maikaʻi i ka hana wela o ka ʻāpana, hoʻemi i ka hoʻohana ʻana i ka lanahu, a hoʻemi i nā hoʻokuʻu CO2. I kēia manawa, ʻo ke ala nui e hoʻomaikaʻi ai i ka pono o nā ʻāpana mana wela e hoʻomaikaʻi i nā ʻāpana mahu a hoʻomohala i nā ʻāpana supercritical (SC) a me ultra-supercritical (USC). I kēia manawa, aia ma mua o 100 miliona-kilowatt ultra-supercritical (USC) pūʻulu i hoʻokomo ʻia ma koʻu ʻāina, e pae mua ana ma ka honua i ka nui a me ka nui o ka hiki.

Heluhelu a me ka wānana o ka hoʻohana ʻana i ka lānahu o ka lako mana lanahu ma Kina mai 2010 a 2020

2.Main Chromium Molybdenum Steel Welding Rod Products

Papa 2 Hōʻike hōʻike hoʻokō o nā electrodes kila mehana pale ʻeleʻele

Nānā:
1. Ua hoʻomohala kā mākou hui i EXXXX-15, EXXXX-16, EXXXX-18 a me nā moʻo hoʻoheheʻe ʻē aʻe no nā electrodes o ka papa like e hoʻokō i nā koi mākeke like ʻole. Hōʻike wale ka mea i luna i ka hana o nā electrodes EXXXX-15.

3.2 Ka papa inoa o nā electrodes kila ferritic/martensitic koʻikoʻi subcritical a super (ultra).

Hōʻike hoʻokō electrode

Nānā:

1. ʻO GER-91M ka hoʻololi hoʻololi, ʻo ia hoʻi, ʻo ke kumu kuʻi he uea kalapona kila maʻamau, a ua hoʻololi ʻia ka alloy nui e ka uhi ʻana. Ke hoʻohālikelike ʻia me GER-91 (ke ʻano hoʻololi uea kumu), ʻoi aku ka maikaʻi o ka waiwai waiwai a ʻo kā mākou super ʻO nā huahana nui o nā koʻokoʻo kuʻi no ka mana wela supercritical.

3. ʻO ka 2015 version of ASME standard e koi i ka E9015-B91 electrode Mn + Ni≤1.4%, aʻo ka 2017 version pono ≤1.2% no ke kumu metala. (2021 ka mana hou o ASME e hoʻohana ana i ka mana 2015 o nā koi haku mele o ASME no nā electrodes E9015-B91/B92). No ka hoʻokō ʻana i ka noi mākeke, ua hoʻomohala kā mākou E9015-B91 a me E9015-B92 i ʻelua ʻano o nā mea hoʻoheheʻe kūpono: Mn + Ni≤1.4% a me Mn + Ni≤1.2%. No ka mea, ʻoi aku ka makemake o ka mākeke, ua hōʻike ʻia ka mea i luna 91/92 electrodes i waiho ʻia me ka metala Mn + Ni≤1.2%.

4. Hōʻike i ka loiloi kaʻina hana no nā electrodes ultra-supercritical
4.1 Kaʻina hana kūpono o nā hui welded P91/92

6. ʻO nā pono a me nā hiʻohiʻona o kā mākou mau electrodes kila wela no ke kila chrome-molybdenum

1. He nui na ano a me na ano a pau

●Ka haku mele mai 0.5%Mo a 9%Cr-3%W-3%Co.
●E hoʻohana i ka mahana mai 500 ℃ a 650 ℃.
● Hiki ke hoʻohana ʻia nā waihoʻoluʻu ʻokoʻa a me nā ʻano uhi (EXXXX-15, EXXXX-16, EXXXX-18) i nā manawa like ʻole (ʻano maʻamau, ʻano ikaika arc ikaika no nā pipeline kūkulu mana).
● Hiki iā ia ke hoʻokō i nā koi wili o ka hapa nui o nā kila Cr-Mo.

2. Hana maikaʻi
ʻO nā waiwai mechanical maikaʻi, maikaʻi ka hana wela kiʻekiʻe (kiʻekiʻe wela wela a me ke kiʻekiʻe wela o ka wā kahiko).

3. Maikaʻi ka hana lima
He maikaʻi loa ka hana ʻana o ka electrode i nā kūlana āpau, kūpaʻa arc combustion, ʻoʻoleʻa maikaʻi a me ka ikaika o ka puhi ʻana, ka liʻiliʻi liʻiliʻi, ka wai maikaʻi, ke ʻano weld nani, a me ka wehe ʻana o ka slag ma hope o ke kuʻi ʻana.

4. ʻOihana alakaʻi
Ua hui pū me Suzhou Institute of Thermal Engineering, a ua hala i ka loiloi o "T / P 91/92 Localization Appraisal Meeting" i ka makahiki 2015, a hui pū me nā mana nui home e like me Shenhua Guohua a me General Iron and Steel Research Institute e hoʻomohala i 650 ° C ʻO G115 kila e kākoʻo ana i nā mea hana a me nā kaʻina hana, a mālama ʻia i kekahi mau hālāwai hoʻololi hoʻopau hoʻohana.
