Ka laulā noi a me nā hiʻohiʻona huahana o ka paipu kila maʻemaʻe

Paipu kila maʻemaʻe ʻolehe aʻO ka paipu kila liʻiliʻi i huki ʻia i ke anume ka pololei kiʻekiʻe a me ka hoʻopau maikaʻi ʻana o ka ʻili no ka hoʻolālā mechanical a me nā mea hana hydraulic.Ke koho ʻana i ka paipu kila seamless pololeino ka hana ʻana i ka ʻōnaehana mechanical a i ʻole nā ​​​​mea hydraulic hiki ke mālama nui i ka manawa mīkini, hoʻomaikaʻi i ka helu hoʻohana waiwai a hoʻomaikaʻi i ka maikaʻi o ka huahana.

No ka loaʻa ʻana o nā paipu kila liʻiliʻi me ka liʻiliʻi a me ka maikaʻi ʻoi aku ka maikaʻi, pono e hoʻohana ʻia ka ʻōwili anu, ke kiʻi anu a i ʻole nā ​​ʻano ʻelua.Hana ʻia ka ʻōwili anuanu ma luna o kahi wili kiʻekiʻe ʻelua, a ʻōwili ʻia nā paipu kila ʻole i loko o kahi annular pass i hoʻokumu ʻia e kahi ʻāpana keʻa ʻokoʻa a me kahi plug conical paʻa.Hoʻokomo pinepine ʻia ke kaha kiʻi anuanu ma luna o 0.5 ~ 100T hoʻokahi kaulahao a i ʻole ʻelua kaulahao anu.

2. ʻO ka paipu kila liʻiliʻi i huki ʻia i ke anu he huahana ia i puka mai i nā makahiki i hala iho nei, no ka mea, ʻo ka lua o loko a me nā ana o ka pā i waho he hoʻomanawanui koʻikoʻi a me ka roughness.

Nā hiʻohiʻona opaipu kila liʻiliʻi ʻole:

1. ʻOi aku ka liʻiliʻi o waho.2. Hiki ke hoʻohana 'ia ke kiʻekiʻe kiʻekiʻe no ka liʻiliʻi liʻiliʻi 3. Kiʻekiʻe kiʻekiʻe o ke anu (rolled) huahana a me ka maikai o ka ili.4. ʻOi aku ka paʻakikī o ke keʻa o ka paipu kila ʻole.5. ʻOi aku ka maikaʻi o ka hana o ka paipu kila ʻole, a ʻoi aku ka paʻakikī o ka metala.ʻO nā paipu kila ʻole no nā hale(GB/T8162-2008) he paipu kila maʻemaʻe ʻole no nā hale maʻamau a me nā hale mīkini.He ʻano paipu kila ʻole i hoʻokaʻawale ʻia e like me kāna mau hoʻohana like ʻole.ʻO ke ʻano o ka hoʻohana ʻana e pili ana i nā ʻano paipu kila seamless structural i hoʻohana ʻia i nā hale ākea a me nā hale mechanical, a me ka nui o nā ʻoihana e like me ke kūkulu ʻana, nā mīkini, ka lawe ʻana, ka mokulele, ka hoʻohana ʻana i ka aila, etc.

ʻO nā ʻokoʻa nui ma waena o ka annealing a me ka normalizing:

1. ʻOi aku ka wikiwiki o ka hoʻoluʻu maʻamau ma mua o ka annealing, a ʻoi aku ke kiʻekiʻe o ka supercooling 2. ʻO ka microstructure i loaʻa ma hope o ka normalizing ʻoi aku ka maikaʻi, a ʻoi aku ka ikaika a me ka paʻakikī ma mua o ka annealing.

Ke koho ʻana i ka annealing a me ka normalizing:

1. Hoʻohana mau ʻia ka Normalizing ma kahi o ka annealing no nā paipu kila liʻiliʻi liʻiliʻi me ka ʻike kalapona ma lalo o 0.25%.no ka mea

No ka wikiwiki hoʻoluʻu ʻana, hiki iā ia ke pale i ka paipu kila liʻiliʻi haʻahaʻa mai ka hoʻokaʻawale ʻana ma ka palena o ka palaoa a me ka neʻe ʻana no ʻekolu mau manawa o ka carburization No ka hoʻomaikaʻi ʻana i ka hana hoʻololi anu o nā ʻāpana stamping;Hiki i ka normalizing ke hoʻonui i ka paʻakikī o ke kila

Machinability o carbon seamless paipu kila;Inā ʻaʻohe kaʻina hana wela ʻē aʻe, hiki i ka normalizing ke hoʻomaʻemaʻe i ka palaoa a hoʻomaikaʻi i ka ikaika o ka paipu kila liʻiliʻi haʻahaʻa.

2.ʻO ka paipu kila maʻemaʻe ʻole i huki ʻia i ke anume ke kalapona ma waena o 0.25 a me 0.5% hiki ke hoʻololi ʻia e ka normalizing

Hoʻololi i ka annealing, ʻoiai ʻo ka paʻakikī o ke anu-unuhi seamless kila paipu o ka waena kalapona kila kokoke i ka palena luna o carbon maʻiʻo ua iki iki ma hope o normalizing kiʻekiʻe, akā, hiki nō ke oki, a me ka normalizing kumu kūʻai haʻahaʻa a me ka huahana kiʻekiʻe. .3.ʻO ka paipu kila liʻiliʻi i huki ʻia me ke kalapona ma waena o 0.5 a me 0.75% he kiʻekiʻe kalapona.

ʻO ka paʻakikī ma hope o ka hana maʻamau ʻoi aku ka kiʻekiʻe ma mua o ka annealing, no laila paʻakikī ke ʻokiʻoki, no laila e hoʻohana i ka annealing piha e hōʻemi i ka paʻakikī a hoʻomaikaʻi i ka machinability.

4. ʻO ke kalapona kiʻekiʻe a i ʻole ke kila kila me ke kalapona maʻiʻo > 0.75% o ka paipu kila maʻemaʻe ʻole i huki ʻia i ke anu e hoʻohana maʻamau i ka pōlele Hoʻohana ʻia ka annealing kemika ma ke ʻano he lāʻau wela mua.Inā loaʻa kahi cementite lua, pono e hoʻopau mua ʻia ke ahi.ʻO Annealing ka mea e wela ai i ka paipu kila liʻiliʻi i huki ʻia i ke anu i kahi mahana kūpono a mālama iā ia no kekahi manawa, Heat mālama kaʻina me ka mālie mālie.ʻO ka hoʻomaha mālie ka hiʻohiʻona nui o ka annealing, a ʻo ka annealing a me ke kiʻi anu ʻaʻole ʻO ka maʻamau, ua hoʻomaha ʻia ka paipu kila ma lalo o 550 ℃ i ka umu.Hoʻohana nui ʻia ka Annealing Hoʻohana pinepine ʻia ka hoʻomaʻamaʻa wela nui e like me ka hoʻomākaukau ʻana i ke kaʻina hana o nā mea hana a i ʻole nā ​​ʻāpana mechanical Ua hoʻonohonoho ʻia ka mālama wela ma hope o ka hoʻolei ʻana, forging a me ka wili a ma mua o ka ʻoki ʻana (ʻoʻoleʻa) e hoʻopau i ke kaʻina hana mua. , a hoʻomākaukau no ka hana ma hope.

Ke kumu hoʻohui: ① e hoʻemi i ka paʻakikī o ka paipu kila maʻemaʻe i huki ʻia i ke anu e hoʻomaʻamaʻa i ka mīkini;② Hoʻopau i nā ʻano ʻano koʻikoʻi e pale i ka deformation o ka paipu kila ʻole i huki ʻia i ke anu;③ E hoʻomaʻemaʻe i ka ʻōpala a hoʻomaikaʻi i ke ʻano o loko.
