310s wela i ʻōwili ʻia i ka papa kila

Hōʻike Pōkole:

310 kuhiliʻole kila i ke kiʻekiʻe kalapona maʻiʻo o 0,25%, ana 310S kuhiliʻole kila i ka haʻahaʻa kalapona maʻiʻo o 0,08%, a me ka 'ē aʻe kemikala e like. No laila, ʻoi aku ka kiʻekiʻe o ka ikaika a me ka paʻakikī o 310 mea kila kila a ʻoi aku ka maikaʻi o ke kūpaʻa o ka pala. ʻOi aku ka maikaʻi o ke kūpale ʻana o 310S mea kila kila a haʻahaʻa iki ka ikaika. 310S mea paʻakikī ke kila kila no ka haʻahaʻa o ke kalapona, no laila kiʻekiʻe ke kumukūʻai.

Ua hōʻuluʻulu ʻia nā ʻokoʻa penei:

1. ʻO 310 ka hoʻohui kemika. ʻO 0.15% ka nui o ke kalapona a ʻo ka 0,00% e pono ai. Eia hou, koi ʻo ia i ka mea MO e ʻoi aku ma mua o ka 0.75%.

2. ʻO ka paʻakikī o ka papa i ka ikaika. 310 ʻoi aku ma mua o 310S

3. ʻOi aku ka nui o ke kūpikipiki 310S ma mua o 310 no ka mea ua hoʻohui ʻo 310S iā MO

4. ʻO ke kiʻekiʻe o ke ana wela 310S o nā kūlana hana like i ʻoi aku ma mua o 310

ʻOkoʻa hou kekahi ma waena o nā wili kila a me nā anuanu i ʻōwili ʻia

Ma ka wehewehe ʻana, paʻakikī i nā ingopa kila a i ʻole nā ​​bila bila i ka deform i ka mahana maʻamau a paʻakikī e hana. ʻO ka maʻamau, hahana lākou i 1100 a 1250 ° C no ke kaʻa ʻana. Kāhea ʻia kēia kaʻina hana e kaʻa nei i ka wela. ʻOlokaʻa ʻia ka hapanui o nā kila e ka kaʻa wela. Eia nō naʻe, no ka maʻalahi o ka ʻili o ka hao i ka pālāki hao hao i ke ana wela kiʻekiʻe, kūpikū ka ʻilikai o ka kila wili wela a piʻi nui ka nui. No laila, pono ke kila me ka ʻoluʻolu, ka nui pololei a me nā pono mīkini maikaʻi e pono ai, a hoʻohana ʻia nā huahana semi-hoʻopau a me nā huahana i hoʻopau ʻia e hoʻohana ʻia e like me nā mea maka a laila anuanu. Iecaianoaaiiuo hana.

ʻO ka ʻōwili ʻana i ka mahana maʻamau ka hoʻomaopopo ʻia he anuanu. Mai kahi kuhi metallographic o ka ʻike, pono e hoʻokaʻawale ʻia nā palena o ke anuanu anuanu a me ka wili wela e ka mahana recrystallization. ʻO ia, ʻo ka ʻolokaʻa ma lalo o ka mahana o ka recrystallization ke anuanu, a ʻo ka ʻolokaʻa kiʻekiʻe aʻe ma mua o ka mahana o ka recrystallization e wela ana. Loaʻa i ka hao kahi mahana recrystallization o 450 a 600 ° C.

ʻO ka wili wela, e like me ka inoa e hōʻike nei, he wela kiʻekiʻe o ka ʻāpana i ʻōwili ʻia, no laila liʻiliʻi ka pale deformation a hiki i kahi nui deformation ke hoʻokō ʻia. Lawe i ka ʻōwili ʻana o ka pepa kila ma ke ʻano he laʻana, ʻo ka mānoanoa o ka hakahaka hoʻolei hoʻomau ʻana ma kahi o 230 mm, a ma hope o ka ʻolokaʻa ʻana a hoʻopau ʻana i ka ʻolokaʻa ʻana, ʻo ka mānoanoa hope loa he 1 a 20 mm. I ka manawa like, ma muli o ka liʻiliʻi o ka lakio ākea ākea o ka pā kila, he haʻahaʻa iki ke koi pono dimensional, a ʻaʻole maʻalahi ka pilikia o ke ʻano, a kaohi ʻia ka convexity. No nā koi o ka ʻahahui, hoʻokō ʻia ia e ka lola ʻana a kaohi ʻia ʻana, ʻo ia hoʻi, ka kaohi ʻana i ka mahana wela, hoʻopau i ke ana wela a me ka mahana wela o ka hoʻopau ʻana e kāohi i ka microstructure a me nā pono mechanical o ka pā.

Ke ʻōwili anuanu, maʻamau ʻaʻohe hana hoʻomehana ma mua o ka ʻoka ʻana. Eia naʻe, ma muli o ka liʻiliʻi o ka mānoanoa o ka holehole, ʻike ʻia ke kinona o ka pā. Eia kekahi, ma hope o ke anuanu, he huahana ia i hoʻopau ʻia, a no laila, i mea e kaohi ai i ka pololei dimensional a me ka maikaʻi o ka lepe, hoʻohana ʻia nā hana paʻakikī. ʻO ka lōʻihi o ke aniani hana lōʻihi lōʻihi, lehulehu nā lako, a paʻakikī ka hana. E like me nā koina a ka mea hoʻohana no ka pololei dimensional, ke ʻano a me ka maikaʻi o ka lepe o ka ʻōpala, ua hoʻomaikaʻi ʻia ke kumu hoʻohālikelike, nā ʻōnaehana L1 a me L2, a me ke ʻano o ke ʻano o ka wili anu anu. Eia kekahi, ʻo ka mahana o nā ʻōwili a me nā kaola kekahi o nā hōʻailona kaohi ʻoi aku ka nui.

ʻOkoʻa ka huahana anu i ʻōwili ʻia a me ka pepa huahana ʻōwili wela mai ka hana ma mua a me ke kaʻina aʻe. ʻO ka huahana ʻōwili wela ka mea maka o ka huahana anu i ʻōwili ʻia, a ʻo ke anuanu i ʻōwili ʻia i ka wili kila i mīkini ʻia e ka hana pickling. ʻO nā wili, ʻolokaʻa, anuanu i hana ʻia, ʻo ka mea nui e ʻolokaʻa i nā ʻāpana wela-i ʻōwili ʻia i mau ʻāpana anuanu-anana, ʻo 0.3-0.7mm maʻamau e ka ʻōwili wela o ka 3.0mm. ʻO ke anuanu i ʻōwili ʻia, ʻo ke kumu nui e hoʻohana i ke kumu extrusion e hoʻoikaika i ka deformation
