ʻO ka ʻokoʻa ma waena o Seamless Tube Continuous Rolling a me Hot Rolling

• ʻO ka ʻōwili mau ʻana o ka paipu maʻemaʻe: ʻO kēia kaʻina hana e pili ana i ka ʻōwili mau ʻana i nā bila i loko o ke ʻano o nā ʻōwili ohe.Hoʻopiʻi mau ʻia ka billet a hoʻohola ʻia e hanapaipu kila ʻoleme ke keakea ole.
• ʻO ka ʻōwili wela: Ma kēia kaʻina hana, ua hoʻomehana mua ʻia ka billet i kahi wela kikoʻī a laila ʻōwili ʻia i loko o nā ʻāpana ʻōwili e hoʻoheheʻe ʻia i loko o kahi paipu ʻole.

ʻO ka lua, ka ʻokoʻa o ke kaʻina hana ma waena o ka ʻōwili mau ʻana a me ka ʻōwili wela:

1. Ka pololei o ka hana ana:

• ʻO ka ʻōwili mau ʻana o ka paipu Seamless: ʻO ka hoʻohana ʻana i nā ʻōwili awelika i ka ʻōwili mau ʻana e hiki ai ke hoʻonui i ka wahi pili, e hōʻemi ana i nā deviations i ka wā o ka ʻōwili ʻana a me ka hopena i ka pololei machining kiʻekiʻe.ʻO ka hoʻomau mau ʻana a me ka hoʻopiʻi ʻana o ka billet e kōkua hou i ka loaʻa ʻana o ka pololei.
• ʻO ka ʻōwili wela: Hiki ke hoʻololi ʻia ka ʻōwili wela e ka wela a me nā mea ʻē aʻe, e ʻoi aku ka maʻalahi o ka deformation ʻole a me ka deformation lima.ʻO ka hopena, ʻoi aku ka haʻahaʻa o ka pololei i loaʻa ma o ka ʻōwili wela e hoʻohālikelike ʻia me ka paipu ʻoleʻolokaʻa mau.

2. ʻO ke ʻano o nā huahana i hoʻopau ʻia:

• ʻO ka ʻōwili mau ʻana o ka paipu maʻemaʻe: ʻO nā huahana i hoʻopau ʻia o ka ʻōwili mau ʻana he ʻano maʻamau me ka liʻiliʻi o nā hemahema a me nā wrinkles.
• ʻO ka ʻōwili wela: ʻO nā huahana i hoʻopau ʻia o ka ʻōwili wela e loaʻa paha nā nicks roll, ʻeleʻele ʻili, a me nā hemahema ʻē aʻe.

3. Ka laulā o ka noi:

• ʻO ka holo mau ʻana o ka paipu Seamless: Ua kūpono kēia kaʻina hana no ka hana ʻana i ka pololei kiʻekiʻe a me ka ikaika kiʻekiʻepaipu kila ʻole, ʻo nā paipu anawaena nui a me nā paipu mānoanoa.
• ʻO ka'ōwili wela:ʻOi aku ka maikaʻi o ka'ōwili wela no ka hanaʻana i nā paipu paʻa lahilahi a me nā paipu kila liʻiliʻi.

ʻEkolu, ʻokoʻa ka hana ma waena o ka ʻōwili mau ʻana o ka paipu ʻole a me ka ʻōwili wela:

1. ikaika:

• ʻO ka ʻōwili mau ʻana o ka paipu seamless: ʻO ka ʻoi aku ka maikaʻi o ka hoʻoponopono ʻana i ka ʻōwili mau ʻana e hopena i ka ikaika pili kiʻekiʻe ma nā paipu kila i hana ʻia.
• ʻO ka ʻōwili wela: Ma muli o ke koʻikoʻi shear i ʻike ʻia i ka ʻōwili wela, hiki ke hoʻololi iki ʻia, e alakaʻi ana i ka ikaika haʻahaʻa i ka hoʻohālikelike ʻia me ka ʻōwili mau ʻana o ka paipu maʻemaʻe.

2. Nā waiwai mīkini:

• ʻO ka ʻōwili mau ʻana o ka paipu Seamless: ʻO ke ʻano o loko o nā paipu i hana ʻia ma o ka ʻōwili mau ʻana ua ʻoi aku ka ʻoi aku o ka ʻoi aku ka maikaʻi o nā waiwai mechanical, ʻoi aku ka nui o ka ikaika tensile a me ka ikaika hua.
• ʻO ka ʻōwili wela: No ka hopena o ka ʻōwili wela e ka wela, ʻoi aku ka liʻiliʻi o ka hale o loko, e alakaʻi ana i nā waiwai mechanical haʻahaʻa.

3. Hana ʻana i ka hana:

• ʻO ka ʻōwili mau ʻana o ka paipu seamless: ʻO nā paipu i hana ʻia ma o ka ʻōwili mau ʻana e hōʻike ana i nā waiwai forging maikaʻi, e kūpono ia no nā koi hana anu a me ka wela.
• ʻO ka ʻōwili wela: Hōʻike ʻia ka ʻōwili wela me ka maikaʻi ʻole o ka hana forging ma muli o ka hopena wela i ka wā o ka hana.

I ka hopena, ʻokoʻa ka ʻōwili mau ʻana a me ka ʻōwili wela ma ke kumu, kaʻina hana, a me ka hana.He mea kūpono ka ʻōwili mau ʻana o ka paipu seamless no ka hana ʻana i ke anawaena nui a me ka pā mānoanoapaipu kilame ka pololei kiʻekiʻe a me ka helehelena maikaʻi.Ma ka lima ʻē aʻe, ʻoi aku ka maikaʻi o ka ʻōwili wela no ka hana ʻana i nā paipu kila lahilahi a me ka liʻiliʻi liʻiliʻi ma ke kumu kūʻai haʻahaʻa.Ma muli o nā pono kiko'ī, hiki i ka poʻe heluhelu ke koho i ke kaʻina hana hana paipu kila.
