ʻenehana hope:

I ka mākeke rebar o kēia manawa, ʻoi aku ka nui o ka hrb400e. ʻO ke ala hoʻoikaika microalloy ke ala nui e hana ai i ka hrb400e i ka honua. ʻO ka microalloy ka nui o ka vanadium alloy a i ʻole ka niobium alloy, ka mea e hoʻopau i ka nui o nā kumu waiwai i kēlā me kēia makahiki. Ma muli o ka liʻiliʻi o nā kumuwaiwai mineral i loaʻa ka vanadium a me ka niobium, paʻa ka hoʻolako ʻana i kēia mau mea hoʻohui. No laila, inā hiki ke hoʻemi ʻia ka ʻike o ka hao hao hrb400e, e hoʻohua nui ia i nā pono waiwai a me ka pilikanaka.

I ka ʻenehana i kēia manawa, ʻo ka laina hana wili pālua me ka ʻole o ka hoʻohaʻahaʻa ʻana a me ka hoʻonui ʻana i ka wili wili e hoʻohana maʻamau i ka hoʻoikaika ʻana i ka vanadium alloy e hana i ka hrb400e, a ʻo ka nui o ka pākēneka o ka vanadium he 0.035% a 0.045%.

Hōʻike ʻo China patent cn104357741a i kahi ʻano hrb400e kiʻekiʻe kiʻekiʻe-ikaika ōlaʻi coil a me kāna hana hana. Ma o ke kaʻina hana, hana ʻia ka huahana i hoʻopau ʻia e ka wili liʻiliʻi a me ka hoʻonui ʻana, hiki ke hōʻoia i ka hoʻopau ʻia ʻana o ke kila i ʻōwili ʻia ma kahi haʻahaʻa haʻahaʻa o 730 ~ 760 ℃ e loaʻa ai No ka ʻai ʻoi aku ka maikaʻi, ʻaʻole kūpono kēia ʻano no nā laina hana. me ka hoemi ole i na wili nui. Hōʻike ka patent Kina cn110184516a i kahi ʻano hoʻomākaukau o ka uwea kiʻekiʻe φ6mm~hrb400e wili wili. Me ke kōkuaʻana o ka ikaika o ka'ōwili o nā mea hana, hoʻomaka ka'ōwili wela haʻahaʻa mai ka mahana wela, aʻikeʻia ka hana me ka microalloying. ʻO ka hemahema o kēia ʻano, ʻo ia nā koi no ka ikaika a me ka hana kaʻa o nā mea ʻala a me nā mea wili liʻiliʻi he kiʻekiʻe, ʻoi aku hoʻi no ka laina hana o ka torsion rolling, e hōʻemi ana i ke ola hoʻokolohua o nā mea hana a hoʻonui i ke kumukūʻai mālama. nā mea hana, a me ka ikaika o ka uwea kiʻekiʻe φ6mm~hrb400e coil i hana ʻia e kēia ʻano hana he koena. ʻAʻole lawa ka nui, paʻakikī ke hōʻoiaʻiʻo i ka helu hoʻokō hana.

Nā mea hoʻokō ʻenehana:

Ke manaʻo nei ka mea hou i kēia manawa e hāʻawi i kahi ala no ka hana ʻana i nā kaola hao liʻiliʻi wela, ʻoi aku ke ʻano no ka hana ʻana i nā snails ʻōwili wela no ka uwea kiʻekiʻe φ8~φ10mm~hrb400e, e lanakila ana i nā hemahema i ʻōlelo ʻia ma luna o ka hana mua a hoʻemi i ka hana. koina.

ʻO ka papahana ʻenehana o kēia mea i hana ʻia:

ʻO ke ʻano o ka hana ʻana o ka pahu kila ribbed wela, ʻo ka kikoʻī o ke koʻokoʻo wīwī wīwī he φ8~φ10mm, a ʻo ke kaʻina hana ʻenehana e pili ana i ka hoʻomehana - billeting - rough rolling - medium rolling - cooling - pre-finishing - cooling - hoʻopau - hoʻomaha - wili - Papakaukau ʻōleʻa hoʻoheheʻe ea—kohi wili—hoʻolili mālie; ʻo ka pākēneka nui o ke kila c=0.20%~0.25%, si=0.40%~0.50%, mn=1.40%~1.60%, p≤0.045%, s ≤0.045%, v=0.015%~0.020%, ʻO ke koena he Fe a me nā mea haumia hiki ʻole ke pale ʻia; ʻO nā kaʻina hana koʻikoʻi: ʻo ka mahana wela o ka umu he 1070 ~ 1130 ℃, ʻo ka prefinishing rolling temperature he 970 ~ 1000 ℃, a ʻo ka hoʻopau ʻana o ka wela wela he 840 ~ 1000 ℃. 880 ℃; kau wela 845~875 ℃; ʻO ka wela kaʻa hope ma lalo o ka mahana recrystallization o ka ʻāpana austenite; ʻO ka hoʻomaloʻo wikiwiki ʻana e ka peʻahi ma ka papa ʻaina hoʻoluʻu ea, ʻo 100% ka nui o ka ea; ʻO ka mahana o ka uhi he 640 ~ 660 ℃, ka mahana o ka uhi mālama wela he 600 ~ 620 ℃, a ʻo ka manawa i ka uhi mālama wela he 45 ~ 55s.
