ʻO ka flange kahi ʻāpana like ʻole i maʻamau i ka ʻenekinia pipeline.ʻO kanā lehelehehoʻohana ʻia i ka lua a me ka hui pū me nā flanges pili i ka valve.I ka ʻenehana pipeline, hoʻohana mua ʻia nā flanges no ka hoʻopili ʻana i nā pipeline.I ka pipeline kahi i hoʻopili ʻia ai nā koi, loaʻa nā ʻano mea like ʻole i kahi pā flange.
Hoʻohālikelike ma waenanā lepa kila kilaanā flanges kila kalapona:
1. He haʻahaʻa ka conductivity thermal, ma kahi o ka hapakolu o ka hao kalapona.No ka pale ʻana i ka ʻino ʻana o ka maka i ka maka ma muli o ka hoʻomehana ʻana i ka uhi flange, ʻaʻole nui ka nui o ke au kuʻi, ʻo ia ka 20% ka liʻiliʻi ma mua o nā koʻokoʻo kuʻi kalapona.ʻAʻole pono e lōʻihi loa ke arc, a wikiwiki hoʻi ka hoʻoluʻu interlayer.Manaʻo ʻia e hoʻohana i kahi pass welding haiki.
2. He kiʻekiʻe ka helu electronegative, ma kahi o 5 mau manawa o ke kila kalapona.
3. He nui ka coefficient o ka hoʻonui laina, 40% kiʻekiʻe ma mua o ke kila kalapona, a i ka piʻi ʻana o ka mahana, hoʻonui pū ka waiwai o ka coefficient o ka hoʻonui laina.
ʻO ke kila kalapona he hao kalapona hao me kahi mea kalapona mai ka 0.0218% a hiki i ka 2.11%.ʻIke ʻia hoʻi he kila kalapona.ʻO ka mea maʻamau, loaʻa pū kekahi mau mea liʻiliʻi o ke silika, manganese, sulfur, a me ka phosphorus.ʻO ka maʻamau, ʻoi aku ka kiʻekiʻe o ke kalapona i loko o ke kila kalapona, ʻoi aku ka nui o ka paʻakikī a me ka ikaika, akā ʻoi aku ka haʻahaʻa o ka plasticity.
He aha nā ʻokoʻa ma waena o ke kila kalapona haʻahaʻa, ke kila kalapona waena, a me ke kila kalapona kiʻekiʻe?
1. ʻO ke kila kalapona haʻahaʻa he ʻano o ke kila kalapona me ke kalapona ma lalo o 0.25%, me ka hapa nui o ke kila kalapona maʻamau a me kekahi kila kila kila kiʻekiʻe, ʻo ka hapa nui o ia mau mea i hoʻohana ʻia no ka ʻenekinia hana ʻenehana ʻaʻole pono ka wela. lapaʻau.Hoʻohana ʻia kekahi i ka carburization a i ʻole ka mālama wela.
2. Medium kalapona kila i maikai Hot hana a me ka oki waiwai, akā, ilihune kuʻihao waiwai.ʻOi aku kona ikaika a me ka paʻakikī ma mua o ke kila kalapona haʻahaʻa, ʻoiai ʻoi aku ka haʻahaʻa o kona plasticity a me ka paʻakikī ma mua o ke kila kalapona haʻahaʻa.Hiki ke hoʻohana pololei ʻia ka ʻōwili anuanu a me nā kaʻina hana ʻē aʻe no ka hoʻomaʻamaʻa anu me ka ʻole o ka mālama ʻana i ka wela, a i ʻole machining a forging hiki ke hana ma hope o ka mālama wela.ʻO ke kila kalapona paʻakikī i loaʻa nā waiwai mechanical piha piha.ʻO ka ʻoi loa o ka paʻakikī e hiki ke loaʻa ma kahi o HRC55 (HB538), σ B ʻo 600-1100MPa.No laila, hoʻohana nui ʻia ke kila kalapona waena i nā noi like ʻole me nā pae ikaika waena.ʻAʻole ia i hoʻohana nui ʻia ma ke ʻano he hale kūkulu hale, akā no ka hana ʻana i nā ʻāpana mīkini like ʻole.
3. Kiʻekiʻe kalapona kila ua kapa pinepine ia Mea hana kila, a me kona kalapona maʻiʻo mea 0.60% ~ 1.70%.Hiki ke kinai a me ka huhū, a ʻilihune kona hana kuʻi ʻana.ʻO nā hāmare, nā kuʻekuʻe, a me nā mea ʻē aʻe i hana ʻia i ke kila me ka maʻi kalapona o 0.75%.ʻO nā mea hana ʻoki e like me nā drills, tap, a me nā reamers he 0.90% ke kalapona.
