Basa rinotonhora rinofa simbi inonyanya kushandiswa pakutsvedza, kushaikwa, kukotama, kutonhora, powanac. Inowanzo kukamurwa kuita mapoka maviri: mhando yemhando uye yakakosha mhando. Semuenzaniso, iyo general-chinangwa inotonhora basa inofa simbi muUnited States kazhinji inosanganisira mana masimbi mamakisi: 01, A2, D2, uye D3. Kuenzanisa kweiyo Speel Giredhi-Chimiro Cold Steal Alloy Kufa Munyika dzakasiyana-siyana dzeShevhizheni, uye 9 Skm China's GB / T1299-2000 Alloy Tool Steel Standard Inosanganisira huwandu hwemhando gumi nembiri, kugadzira yakateedzana yakazara. Nekuchinja kwekugadzirisa tekinoroji, yakagadziriswa zvinhu uye inoda kuumbwa, iyo yekutanga yekutanga nyaya haigoni kusangana nezvinodiwa. MaJapan Steel Mairi uye Mukuru weEuropean Old Vakagadzira Basa Rekutonhora Rakafa Simbi
Low Alloy Mhepo Kupedzisa Yakatonhora Basa Rinofa Simbi
Nekuvandudzwa kwekupisa kwehurongwa hwekuita tekinoroji, kunyanya kushandiswa kwekushandiswa kweVaPutching tekinoroji muIndia Indasitiri, Vamwe Vakaderera Mhepo-Yakadzima Mhepo-deform Steels yakagadzirwa kumba uye kune dzimwe nyika. Rudzi urwu rwesimbi runoda kuomarara kwakanaka uye kurapa kwekushisa kuve nehuremu hushoma, simba rakanaka nekuomesera, uye kune imwe kupfeka kupokana. Kunyangwe yakajairwa yakakwirira-alloy inotonhora basa izere simbi (yakadai seD2, A2) ine kuomarara kwakanaka, ine zvirimo zvakakura zvezvinyorwa uye zvinodhura. Naizvozvo, vamwe vakaderera-micro-deform deform simbi yakagadzirwa kumba uye kunze kwenyika. Rudzi urwu rwesimbi runowanzove neiyo allow zvinhu cr uye mn alloy zvinhu zvekuvandudza hardenability. Izvo zvakazara zvemukati zveAlloy zvinhu zvinowanzo <5%. Izvo zvakakodzera kugadzira zvikamu zvakanyatsojeka nemabheti madiki ekugadzira. Kuomarara. Mumiriri weSteel Giredhi anosanganisira A6 kubva kuUnited States, ACD3 kubva kuDido Simbi, etc. Chinese GD Simbi, Inogona kushandiswa kuita kutonhora kutonhora kunofa iyo inowanzo popp uye kupwanya. Hupenyu hweShete High.
Murazvo wakabvisa mold simbi
Kuti ipfupise kutenderera kweMold Kugadzira, kurerutsa iyo yekupisa kurapa maitiro, chengetedza simba uye kuderedza mutengo wekugadzira wechiumbwa. Japan yakagadzira rimwe basa rinokosha rinotonhora rinofa ngowani dzemurazvo unopedza zvinodiwa. Zvakafanana Rudzi urwu rwesimbi runogona kushandisirwa kupisa banga kana zvimwe zvikamu zveMolDe uchishandisa Oxecetylene Spray Pfuti kana imwe heaters mushure mekuumbwa kwemhepo uye wozotonhorera mhepo uye yakadzimwa. Kazhinji, inogona kushandiswa zvakananga mushure mekupedzisa. Nekuda kwekuita kwayo nyore, inoshandiswa zvakanyanya muJapan. Mirairo yesimbi yesimbi yerudzi urwu rwesimbi ndeye 7crsimmov, iyo ine kuomarara kwakanaka. ENT 800mm simbi isimbi yakadzimwa, kuomarara kwechikepe che 30mm kubva kumusoro kunogona kusvika 60hrc. Musiyano wacho mukuomarara pakati peiyo core uye iyo nzvimbo ndeye 3hrc. Kana murazvo unopedza
Kuomarara kwakanyanya, yakakwira kupfeka basa rekudzikisira rinotonhora rinofa simbi
Kuti vazivise kuomarara kwebasa rinotonhora kufa uye kuderedza kuparara kwesimbi, mamwe makambani makuru ekuumbwa akagadzirwa akabata akatevedzana basa rekutonhora rinogona kuomarara nekukwira zvakanyanya uye nekukwira kupokana. Rudzi urwu rwesimbi runowanzove neinenge 1% kabhoni uye 8% cr. Nekuwedzera kweMo, v, si uye zvimwe zvinopihwa zvinhu zvakaringana, zvakanyanyisa kuomarara, uye kuomarara kwacho kwakanyanya kupfuura iyo yeiyo yeCr12 mhando Simbi, nepo kupfeka kwaro kupokana kwakafanana. . Kuomesa kwavo, simba rinoshanduka, kusimba kuneta nekuomesesa kupwanya zvakakwirira, uye kusakwana kwavo kwekunyepedzera kwakakwira zvakare kupfuura CRL2 Type YAKABUDA STEL. Ivo vakakodzera kune yakakwira-kumhanya proves uye akawanda-chiteshi punches. Mumiriri weSimbi mhando dzemhando iyi yesimbi ndeye Japan's DC zvemukati zvemukati uye cru-pfeka ine yakakwira v ilmeni. DC53 inodzimwa pa1020-1040 ° C uye kuomarara kunogona kusvika 62-637hc mushure mekutonhora kwemhepo. Inogona kutsamwiswa pakudziya kwakadzika (180 ~ 200 ℃) uye yakanyanya kupisa temperating (500 ~ 550 ℃), kuoma kwayo kunogona kuita ka1, uye kuita kwayo kwekuneta ndeye 20% yakakwirira kupfuura D2; Mushure me crum-rolling, yakashongedzwa uye austenitised pa 850-870 ℃. Asingasviki makumi matatu ℃ / awa, akadonhedza kusvika ku650 ℃ uye akaburitswa, kuomarara kunogona kusarudzwa mumamiriro ezvinhu ekushandisa
Base simbi (yakakwira-kumhanya simbi)
Yakakwira-yekumhanyisa yakashandiswa zvakanyanya kunze kwenyika yekugadzira yakakwirira-kuita, hupenyu hwese husingawanzoita nekuomarara kweJapan yakakwira, yakadai Kuti ugadzirise kune zvinodiwa zveMold, kuoma kunowanzovandudzwa nekudzora tembiricha yekudzima, kudzima kuomarara kana kuderedza iyo kabhoni mukati menel. Metrix Simbi inokudziridzwa kubva kumusoro-yekumhanyisa simbi, uye kuumbwa kwayo kwemakemikari kwakaenzana neiyo matrix kuumbwa kweiyo yepamusoro-yekumhanyisa simbi mushure mekupedza. Naizvozvo, nhamba yezororo remapepa edzidzo mushure mekupiswa idiki uye kugoverwa kugovera, izvo zvinovandudza kuomarara kweiyo simbi kuenzaniswa neyekumhanya-kumhanya simbi. Iyo United States neJapan yakadzidzwa base simbi nemakiromita vasofa, vascomatrix1 uye mod2 kutanga kwema1970s. Munguva pfupi yapfuura, Drm1, DrM2, DrM3, etc. yakagadzirwa. Kazhinji inoshandiswa kune inotonhora basa kuumbwa izvo zvinoda zvakakwirira zvakanyanyisa uye zviri nani anti-tendeuka kugadzikana. China zvakare yakagadzira mamwe masimbi, senge 65nb (65cr4w3mo2vnb), 65W8CR4VTI, 65Cranc53w2vsiti uye mamwe madha. Rudzi urwu rwesimbi rune simba rakanaka uye runyararo runyararo rwekutonhora, tambo dzinotonhora dzinotonhora, kufungidzira kunofa, etc., uye kunogona kushandiswa sekuwedzera kunofa.
Podder Metallurgy Mold Simbi
LELB-Type High-Alloy Yakatonhora Basa Rakagadzirwa neChidimbu Maitiro, ane COUTECASE Carbides uye kugoverwa zvisina kujairika, ayo anoderedza zvakanyanya kuoma, kugeza uye kugeda uye isotropy yeiyo simbi. Mumakore achangopfuura, makambani makuru ekune mamwe masimbi anogadzira chishandiso uye anofa akasangana nekukudziridza nhanganyaya yeSimbi yakakwira uye yakakwirira-alloy izere simbi, iyo yakatungamira kukurumidza kukura kwerudzi urwu rwesimbi. Uchishandisa poda metallurgy process, iyo atomed simbi poda inotonhorera nekukurumidza uye macarbes akaumbwa zvakanaka uye yunifomu, iyo inovandudza kuomesa, geza uye isotropy yezvinhu zviumbwa. Nekuda kweiyi inokosha yekugadzira maitiro, iyo katuni yakanaka uye yunifomu, uye yekukuvara nekukuya kwakavandudzwa, kubvumira yakakwira kabhoni uye nekukasira kukudziridza marudzi esimbi. Semuenzaniso, iyo Japan's Datong's Dex Series (Dex40, dex60, diac.), Hitachi Metal's Fakita, uye yeAmerican Computis's Powder yeStullurgy Tool uye kufa simbi iri kukura nekukurumidza. Kugadzira nhevedzano yepfuma yemasita metallurgy simbi senge cpmlv, CPMLOV, CPMLOV, etc
