Tšepe ea hlobo -(mold ea embryo ea botlolo / PET hlobo / tube billet hlobo / hlobo ea ente)
Tlhaloso ea tšepe
Tšepe e bua ka motsoako oa tšepe oa carbon o nang le khabone ea 0.0218% ~ 2.11%.Tšepe ea alloy e ka fumanoa ka ho kenyelletsa Cr, Mo, V, Ni le likarolo tse ling tsa alloy ka tšepe e tloaelehileng, 'me litšepe tsohle tsa rona tsa hlobo ke tsa tšepe ea alloy.
Ho na le mekhoa e meraro ea mantlha ea ho fetola thepa ea tšepe:
Motsoako oa motsoako
Khabone: C
Eketsa ho thatafala ha lisele tse thata;
Ho thehoa ha carbide, ho ntlafatsa ho hanyetsa ho apara;
Fokotsa boima ba 'mele;
Ho fokotseha ha solderability
Kr: Kr
Ntlafatsa ho thatafala ha tšepe, ho etsa chromium carbide e thata le e tsitsitseng, kahoo e ntlafatsa ho hanyetsa ho apara;
E ka ntlafatsa ho thatafala ha tšepe;
Ha litaba tsa Cr li feta 12%, ha li na kutu 'me li fana ka potoloho e ntle ea ho bentša
Mo, Mo
Mo ke karolo e matla ea ho etsa carbide, e ntlafatsa ho hanyetsa ho apara;
Mo> 5% e ka thibela ho tsieleha ha bohale ho bakoang ke likarolo tse ling tsa motsoako.
E fana ka boima bo bofubelu, matla a mocheso;
Ntlafatsa ho thatafala le botsitso ba bohale
V: V
E ka theha carbide e thata haholo, e ntlafatsa ho hanyetsa ho roala;
Ntlafatsa boholo ba lijo-thollo tsa tšepe ho fokotsa kutloelo-bohloko e feteletseng
Ntlafatsa matla a tšepe, ho tiea le ho tsitsisa ha mocheso
Nickel: Ha ho joalo
Ni ka ntlafatsa ho thatafala ha tšepe;
Ke ka hloekisa lijo-thollo
Sebabole (S)
Hangata e teng ka tšepe ka mokhoa oa MnS, e ka ntlafatsang bokhoni ba ho seha thepa ka ho senya ho tsoela pele ha matrix le ho senya ho tiea, ho hanyetsa kutu, ho pota-pota ka mahlo, ho ntša machining le thepa ea etching ea thepa.
2. Mokhoa oa ho qhibilihisa
Mokhoa o tloaelehileng oa ho etsa litšepe
Electroslag remelting (ESR)
The billet kaba behoa ka sebōpi electroslag, 'me hona joale e matla e fetiswa ho etsa hore sebōpi hlahisa mocheso phahameng haholo, e le hore billet kaba e qhibiliha ka tšepe e qhibilihisitsoeng, e phallang ka electroslag, le litšila tse tlhotliloeng le adsorbed ke. electroslag, e le ho finyella phello ea tlhoekiso.Sekhahla sa ho qhibiliha ka kakaretso se potlakile, empa litšila tse ling tse ntle haholo ha li tlosoe.
Vacuum arc remelting (VAR)
Ka sebōping sa vacuum, motlakase o matla o sebelisoa ho embryo ea tšepe, karolo e ka tlaase ea lesea e qala ho qhibiliha, 'me litšila li fetoha mouoane ho ba khase' me li pompeloe, kahoo li ntlafatsa bohloeki ba tšepe.Ho feta moo, e tiisitsoe lerotholi ka lerotholi, ka lebelo le tiileng la ho tiisa, 'me lisele li fetoha tse teteaneng haholo.E khetholloa ka ho tlosoa ka ho feletseng ha litšila, empa tekanyo ea ho qhibiliha ka kakaretso e lieha.
3. Kalafo ea mocheso
Phekolo ea mocheso ea tšepe e bua ka mokhoa oa ho futhumatsa le ho pholisa, le ho fetola thepa ea tšepe ka ho laola mocheso oa mocheso, ho tšoara nako le lebelo la ho pholile la tšepe, e le ho finyella litlhoko tsa ho sebetsa kapa ho sebelisoa.
Mekhoa e ka sehloohong ea phekolo ea mocheso ke: annealing, quenching, tempering.
Die steel e arotsoe ho latela tšebeliso
1. Cold sebetsa die steel
Cold work die steel e sebelisoa haholo ho etsa hlobo bakeng sa ho hatella workpiece e batang.Joalo ka ho felloa ke litebele tse batang, ho otla ka setempe ho batang, ho totoba ho batang ho shoa, ho khokhotha ho shoa, lefu le batang la extrusion, ho hatelloa ha khoele le lefu la ho hatella phofo.Litšepe tse batang tsa ho sebetsa ho tloha ho litšepe tse fapaneng tsa lisebelisoa tsa k'habone, litšepe tsa lisebelisoa tsa alloy, litšepe tsa lisebelisoa tsa lebelo le holimo ho isa ho litšepe tsa phofo tse lebelo le phahameng le phofo e phahameng ea alloy die steels.
2. Mosebetsi o chesang shoela tšepe
Hot work die steel e sebelisoa haholo-holo ho etsa die bakeng sa machining khatello ea workpiece tlas'a mocheso o phahameng.Joalo ka ho forging die, hot extrusion die, die casting die, lefu le chesang le halefisang.Mosebetsi o tloaelehileng o sebelisoang ho chesa tšepe ea die steel ke: tšepe e bohareng le e phahameng ea carbon alloy e nang le Cr, W, Mo, V le likarolo tse ling tsa alloy;High alloy austenitic heat resistant steel steel ka linako tse ling e sebelisoa ho etsa tšepe ea tšepe e chesang e nang le litlhoko tse khethehileng.
3. Tšepe ea hlobo ea polasetiki
Ka lebaka la mefuta e fapaneng ea polasetiki, litlhoko tsa lihlahisoa tsa polasetiki le tsona li fapane haholo, ho etsoa ha thepa ea hlobo ea polasetiki ho boetse ho beha litlhoko tse fapaneng tse fapaneng.Ka hona, linaha tse ngata tse tsoetseng pele indastering li thehile letoto la litšepe tsa hlobo ea polasetiki.Ho kenyeletsoa carbon structural steel, carburizing die steel, pre-hardening die steel, pre-hardening die steel, corrosion resistant plastic die steel, polasetiki ya die steel, polasitiki e thata ya die steel, le diipone tse bentshang die steel. .
