Ⅰ-He aha ka Cr12MoV Cold Working Die Steel
ʻO ka Cr12MoV cold working die steel i hana ʻia e zhongao no ka ʻāpana 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 ka zhongao's Cr12MoV mold steel he kiʻekiʻe hardenability, me kahi ʻāpana ma lalo o 400mm hiki ke hoʻopau piha ʻia, a hiki ke mālama i ka paʻakikī maikaʻi a me ke kūpaʻa ʻana ma 300-400 ℃.Ma waho aʻe o kēia, ʻoi aku ka paʻakikī o ke kila Cr12MoV o zhongao 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 quenching.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 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 o Cr12MoV Cold Working Die Steel
① Hiki ke hoʻohana ʻia ʻo Cr12MoV no ka hana ʻana 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.
② No ka hanaʻana i nā kuʻi a me nā'āpana concave e koi ana i ke kū'ē kū'ē kiʻekiʻe, ua'ōleloʻia e loaʻa ka paʻakikī o 60 ~ 62HRC i ka wā e hana ai i ka punch a me 62 ~ 64HRC i ka hanaʻana i ka mold concave.
③ No ka hana ʻana i nā ʻāpana concave kūʻokoʻa i loko o nā pahu kiʻi hohonu, ʻoi aku ka paʻakikī o 62 ~ 64HRC.
④ Hoʻohana ʻia no ka hana ʻana i nā mole convex, concave molds, a me ka hoʻokomo ʻana i nā poloka e koi ai i ke kūpaʻa ʻaʻahu kiʻekiʻe a me nā ʻano paʻakikī i nā poʻo 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.
⑤ No ka hana ʻana o ka extrusion anu make a make no nā ʻāpana alumini, ʻoi aku ka paʻakikī o 60-62HRC i ka wā e hana ai i nā make, a me 62-64HRC i ka wā e hana ai i ka make.
⑥ Manaʻo ʻia e hoʻohana i ka paʻakikī o 62 ~ 64HRC no ka convex a me ka concave mold i hoʻohana ʻia no ka hana ʻana i nā mold extrusion copper cold extrusion.
⑦ Hoʻohana ʻia ka convex a me ka concave i hoʻohana ʻia no ka hoʻoheheʻe ʻana i ke kila anuanu e loaʻa ka paʻakikī o 62 ~ 64HRC.
⑧ ʻO nā papa kila puna me ka hapa nui o 0.65% ~ 0.80% i hoʻohana ʻia no ka hoʻokumu ʻana i ke kalapona he paʻakikī o 37 ~ 42HRC, e hāʻawi ana i ke ola a hiki i 150000 cycles.
⑨ ʻO nā pā 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-Ka hana ʻana o Cr12MoV Cold Working Die Steel:
Nā kikoʻī no ka palupalu ʻana o ka mold extrusion anu: E pale a hoʻomehana i ka mold me nā faila hao ma kahi mahana o 760-780 ℃ no 10 mau hola, me ka hoʻoheheʻe ʻana o ka umu 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 hola, hoʻoluʻu i ka umu i 740-760 ℃ × 4-5 mau hola o ka mālama isothermal, me ka paʻakikī o ka ea ≤ 241HBW, eutectic carbide grade ≤ 3, isothermal maikaʻi loa. mahana 740-76o ℃, a me ka manawa ≥ 4-5 hola.
Nā kikoʻī no ka spheroidizing annealing: (860 ± 10) ℃ × 2-4 mau hola, ka hoʻoheheʻe ʻana o ka umu ahi ma kahi 30 ℃ / hola, (740 ± 10) ° C x 4-6 mau hola, hoʻomaha mālie i ka 500-600 ℃ me kapuahi, hooluolu ea ma hope o ka hemo ana, paakiki 207-255HBW.
Nā kikoʻī hoʻopiʻi maʻamau a me ka hoʻoheheʻe ʻana: ke ana wela 1000-1050 ℃, ka ʻaila quenching a i ʻole ka hoʻopau ʻana, ka paʻakikī 260HRC, ka mahana wela 160-180, ka manawa hoʻonā 2 mau hola, a i ʻole ka mahana wela 325-375 ° C, ka hoʻoulu ʻana 2-3 mau manawa.
ʻO ke ana wela haʻahaʻa a me ka hoʻihoʻi haʻahaʻa quenching wela: 950 ℃ -1040 ℃, ʻo ka mahana wela ma kahi o 200 ℃.
Kiʻekiʻe quenching a me ka hoʻi kiʻekiʻe quenching wela: 1050-1100 ℃, tempering wela ma kahi o 520 ℃, 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: Ke hana nei ke kila Cr12MoV 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 zhongao 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 kiʻi kiʻi make no Zhongao's Cr12MoV stainless steel utensils, ma hope o ke kinoea nitrocarburization lapaʻau, hiki i 30000 ʻāpana, ʻoi aku ia ma mua o 10 mau manawa ʻoi aku ka lōʻihi ma mua o nā ʻano like ʻole i mālama ʻia me ka quenching maʻamau a me ka hoʻoulu ʻana.
