Ⅰ-He ahaʻO Cr12MoV ʻO ke kila hana anuanu
ʻO ka Cr12MoV anuanu hana make kila i hana ʻia e Jinbaicheng no ke kāʻei o ke kila kila micro deformation kiʻekiʻe, kahi i hōʻike ʻia e ke kūpaʻa lole kiʻekiʻe, hardenability, micro deformation, high thermal stability, high bending strength, a me nā waiwai ʻē aʻe.ʻO ia ka lua wale nō i ke kila kiʻekiʻe a he mea koʻikoʻi no ka hoʻopaʻa ʻana, ke poʻo anu, a me nā mea ʻē aʻe.Cr12MoV make kila he kalapona molybdenum ledeburite kila me ka haʻahaʻa kalapona ma mua o Crl2 kila.Hoʻohui ʻia ka Molybdenum a me ka vanadium e hoʻomaikaʻi i ka hana hana wela, ka paʻakikī o ka hopena a me ka hāʻawi ʻana i ka carbide o ke kila.ʻO ke kila make Cr12MoV ka haʻahaʻa haʻahaʻa o ke kalapona ma mua o ke kila make Cr12.ʻO ka hoʻohui ʻana i nā mea hoʻohui hou e hoʻomaikaʻi i ke ʻano o ka carbide uneven.Eia kekahi, hiki i ka molybdenum a me ka molybdenum ke hōʻemi i ka hoʻokaʻawale carbide a hoʻomaikaʻi i ka paʻakikī.Hiki i ka Vanadium a me ka vanadium ke hoʻomaʻemaʻe i ka palaoa a hoʻonui i ka paʻakikī, no laila, ʻo Jin Baicheng's Cr12MoV mold steel he kiʻekiʻe hardenability, me kahi ʻāpana keʻa ma lalo o 400mm hiki ke hoʻopau loa, a hiki ke mālama i ka paʻakikī maikaʻi a hoʻopaʻa i ke kūpaʻa ma 300-400℃. Besides, ʻOi aku ka paʻakikī o ko Jinbaicheng's Cr12MoV mold steel ma mua o nā mea ʻē aʻe o ka papa like ma ka mākeke maʻamau, a ua hoʻemi nui ʻia ka hiki ke hoʻololi i ka leo i ka wā hoʻopau.No laila, ʻoi aku ka maikaʻi o kona pale ʻana i ka lole a me nā waiwai mechanical piha maikaʻi i ka Jinbaicheng's Cr12MoV mold steel i kūpono no ka hana ʻana i nā ʻāpana like ʻole me ka ʻāpana nui, ʻano paʻakikī, a kūpaʻa i nā hopena nui, a me nā mea hana hoʻoheheʻe anuanu ma lalo o nā kūlana hana koʻikoʻi, e like me make kuʻi, make ʻoki ʻoki, make ʻolokaʻi, etc. ʻO ka pā hao kila hohonu kiʻi make, ʻike pōʻai, nā mea hana maʻamau a me nā mea ana ʻana, ka make o ka ʻōwili, etc.
Ⅱ-Alakaʻi noi of ʻO Cr12MoV ʻO ke kila hana anuanu
①Hiki ke hoʻohana ʻia ʻo Cr12MoV e hana i nā ʻano paʻakikī o ka convex, concave, a me ka hoʻokomo ʻana i nā poloka no ke kuʻi ʻana i nā ʻōpala me ka mānoanoa waiwai>3mm.Manaʻo ʻia e loaʻa ka paʻakikī o 58 ~ 62HRC i ka wā e hana ai i nā mold convex a me 60 ~ 64HRC i ka wā e hana ai i nā mold concave.
②No ka hanaʻana i ka punch a me ka concave mold e koi ana i ka pale lole kiʻekiʻe, ua'ōleloʻia e loaʻa ka paʻakikī o 60 ~ 62HRC i ka hanaʻana i ka punch a me ka 62 ~ 64HRC i ka hanaʻana i ka mold concave.
③No ka hana ʻana i nā ʻāpana concave kūpaʻa i loko o nā pahu huki hohonu, ʻōlelo ʻia e loaʻa ka paʻakikī o 62 ~ 64HRC.
④Hoʻohana ʻia no ka hana ʻana i nā ʻāpana convex, nā ʻāpana concave, a me nā poloka hoʻokomo e koi ai i ke kūpaʻa ʻaʻahu kiʻekiʻe a me nā ʻano paʻakikī i loko o nā pahu kulou.Manaʻo ʻia e loaʻa ka paʻakikī o 60-64HRC i ka wā e hana ai i nā mole convex, a me 60-64HRC i ka wā e hana ai i nā mole concave.
⑤No ka hana ʻana o ka extrusion anu make a make no nā ʻāpana alumini, ua ʻōlelo ʻia e loaʻa ka paʻakikī o 60-62HRC i ka wā e hana ai i ka make, a me 62-64HRC i ka wā e hana ai i ka make.
⑥Manaʻo ʻia e hoʻohana i ka paʻakikī o 62 ~ 64HRC no ka convex a me ka concave molds i hoʻohana ʻia no ka hana ʻana i ke keleawe anu extrusion molds.
⑦ʻO ka convex a me ka concave molds i hoʻohana ʻia no ke kila anu extrusion molds e paipai ʻia e loaʻa ka paʻakikī o 62 ~ 64HRC.
⑧ʻO nā papa kila puna me ka hapa nui o 0.65% ~ 0.80% i hoʻohana ʻia no ka hana ʻana i ke kalapona i ka paʻakikī o 37 ~ 42HRC, e hāʻawi ana i ke ola o ka 150000 cycles.
⑨ʻO nā papa kila puna me ka hapa nui o 0.65% a 0.80% i hoʻohana ʻia no ka hana ʻana i ke kalapona he paʻakikī o 37-42HRC, a me ka mālama nitriding hou, hiki i ko lākou ola lawelawe ke hiki i 400000 mau manawa.
Ⅲ-Kaʻina hana of ʻO Cr12MoV ke kila hana anuanu:
Nā kikoʻī no ka palupalu ʻana o ka mold extrusion anu: Pale a hoʻomehana i ka ʻōpala me nā faila hao ma kahi mahana o 760-780℃no 10 mau hola, me ka hoʻoluʻu ʻana o ka umu ahi a me ka paʻakikī o 196HBW.Hiki ke hoʻokō maʻalahi ka hoʻokumu ʻana i ka extrusion anuanu.
Hōʻike no ka isothermal spheroidizing annealing maʻamau: 850-870℃ ×3-4 mau hola, hoʻoluʻu i loko o ka umu i 740-760℃ ×4-5 mau hola o ka mālama ʻana i ka isothermal, me ka paʻakikī ea≤241HBW, eutectic carbide māka≤3, maikaʻi loa isothermal wela 740-76o℃, a me ka manawa≥4-5 hola.
Nā kikoʻī no ka hoʻopili ʻana i ka spheroidizing: (860± 10)℃ ×2-4 mau hola, hoʻoluʻu i ka umu ma kahi o 30 mau hola℃/ hola, (740± 10)° C x 4-6 mau hola, hoʻoluʻu mālie a hiki i 500-600℃me ka umu ahi, ka ea hoʻoluʻu ma hope o ka hoʻokuʻu ʻana, paʻakikī 207-255HBW.
ʻO nā kikoʻī hoʻopiʻi maʻamau a me ka hoʻoheheʻe ʻana: quenching temperature 1000-1050℃, ka aila kinai a kinai paha, paakiki 260HRC, ka wela wela 160-180, ka manawa hooluolu 2 hola, a i ole ka wela wela 325-375° C, hoʻonāuki i nā manawa 2-3.
Haʻahaʻa quenching a hoʻi haʻahaʻa quenching wela: 950℃-1040℃ʻO ka mahana wela ma kahi o 200℃, ka hoʻohaunaele lua.
Kiʻekiʻe quenching a me ka hoʻi kiʻekiʻe quenching wela: 1050-1100℃, ʻo ka mahana wela ma kahi o 520℃, ka hoʻohaunaele lua.ʻO ke ʻano hana paʻakikī lua i hoʻohana ʻia no ke kinai kiʻekiʻe a me ka hana hou ʻana e hoʻomaikaʻi i ka paʻakikī, akā e ulu ka hua.
Hoʻomaʻamaʻa Cryogenic: ʻO ke kila Cr12MoV e hana i ka mālama cryogenic, hiki ke hoʻoheheʻe i nā carbide ultrafine i hoʻopuehu nui ʻia mai ka martensite quenched, a laila hiki ke hoʻololi ʻia kēia mau carbide ultrafine i carbide ma hope o 200℃haʻahaʻa haʻahaʻa haʻahaʻa.ʻO ka martensite me ka mālama ʻole cryogenic e hoʻoheheʻe wale i kahi carbide liʻiliʻi ma kekahi mau wahi kūloko ma hope o ke ahi circumferential wela haʻahaʻa.
Hoʻohana ʻo Jinbaicheng i kahi ʻano hoʻomaʻamaʻa haʻahaʻa haʻahaʻa haʻahaʻa, e mālama ana i ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana o ke kila Cr12MoV.ʻEkolu mau papa hoʻomaʻamaʻa haʻahaʻa haʻahaʻa kemika, ʻo ia hoʻi ka ion nitriding, gas nitrocarburizing, a me ka ʻauʻau ʻauʻau sulfur cyanide co nitriding, loaʻa ka hopena koʻikoʻi a me ka hoʻopili ʻana, me ka ʻauʻau paʻakai sulfur cyanide co nitriding ka mea maikaʻi loa.
ʻO ke ola lawelawe o ke kaha kiʻi make no Jinbaicheng's ʻO nā mea kila kila Cr12MoV, ma hope o ka mālama ʻana i ka nitrocarburization gas, hiki i nā ʻāpana 30000, ʻoi aku ka nui ma mua o 10 mau manawa ma mua o nā ʻano like ʻole i mālama ʻia me ka quenching maʻamau a me ka tempering.
