1,Ke mefuta efe ea tšepe
1. 40Cr, 42CrMo, joalo-joalo: E bua ka tšepe ea alloy structural, e nang le matla a matla a mocheso o phahameng le ho hanyetsa mokhathala, 'me hangata e sebelisetsoa ho etsa likarolo tsa bohlokoa tsa lisebelisoa tse kholo tsa mechine.Moetso oa machaba oa tšepe oa ASTM A3 ke tšepe e tloaelehileng ea Amerika ea sebopeho sa khabone, e nang le thepa e itekanetseng ea mochini mme e sebelisoa hangata ha ho etsoa likarolo tse tloaelehileng tsa sebopeho.
2. Mefuta e ka sehloohong ea tšepe e kenyelletsa tšepe e khethehileng ea carbon structural steel, carbon tool steel, carbon spring steel, alloy spring steel, alloy structural steel, alloy structural steel, alloy tool steel, alloy tool steel, high-speed tool steel, high-speed tool steel, stainless steel. , tšepe e sa keneleng mocheso, hammoho le li-alloys tse nang le mocheso o phahameng, li-alloys tse nepahetseng, le lisebelisoa tsa electrothermal.
3. Boleng ba E: 26 bakeng sa mehlala e akaretsang le ba nang le a, 44 bakeng sa ba nang le b, le 24 bakeng sa ba nang le c.Karolo ka 'ngoe ea bolelele e ka limilimithara.Litekanyo tsa bolelele ba tšepe li bua ka litekanyo tsa mantlha tsa mefuta e fapaneng ea tšepe, ho kenyelletsa bolelele, bophara, bophahamo, bophara, radius, bophara ba kahare, bophara ba kantle le botenya ba lebota.
4. Tšepe ka kakaretso e arotsoe ka mekhahlelo e mene: profiles, lipoleiti, thepa ea mohaho le liphaephe.Lisebelisoa tsa profiles le lipoleiti li arotsoe haholo e le Q235B, Q345B, le Q355B, athe thepa ea mantlha ea thepa ea moaho ke HRB400E, 'me thepa ea liphaephe le eona haholo-holo Q235B.
Mefuta ea profiles e kenyelletsa tšepe e bōpehileng joaloka H, tšepe e bōpehileng joaloka I, tšepe ea mocha le tšepe ea angle.
5. Tšepe e khethehileng: e bua ka tšepe e khethehileng e sebelisoang likarolong tse fapaneng tsa indasteri, tse kang tšepe ea likoloi, tšepe ea mechine ea temo, tšepe ea sefofane, tšepe ea ho etsa mechine, tšepe ea ho futhumatsa sebopi, tšepe ea motlakase, terata ea welding, joalo-joalo. litlhaloso tsa lihlahisoa tse fapaneng tsa liphaephe tse cheselitsoeng li boetse li fapane, hangata li hlahisoa ka bophara ba lebitso.
2, Mokhoa oa ho khetholla mefuta le mehlala ea tšepe
1. Ho ea ka litšebeliso le litlhoko tse fapaneng, tšepe e ka aroloa ka mefuta e sa tšoaneng le mehlala.Tšepe ea carbon e hlophisitsoeng ka sebopeho sa lik'hemik'hale: Tšepe e nang le khabone e pakeng tsa 008% le 11%, e sebelisoang haholo ho etsa likarolo tsa mochini, mabili, lipina, joalo-joalo.
2. Tlhaloso ea Classification ea mokhoa oa ho emela boemo ba tšepe Chaena: 1. Tšebeliso ea tšepe ea carbon structural e entsoe ka letšoao la Q + nomoro + ea boleng + letšoao la mokhoa oa deoxygenation.Sehlopha sa eona sa tšepe se ngotsoe ka "Q", se emelang ntlha ea lihlahisoa tsa tšepe, 'me linomoro tse latelang li emela boleng ba ntlha ea lihlahisoa, ho MPa.Ka mohlala, Q235 e emela ntlha ea lihlahisoa ( σ s) 23 MPa carbon structural steel.
3. Tšepe e arotsoe ka mefuta e mene: profiles, lipoleiti, thepa ea mohaho le liphaephe.Har'a tsona, li-profile le lipoleiti li ka aroloa ka Q235B, Q345B, le Q355B, ha thepa ea mohaho e le HRB400E le liphaephe ke Q235B.Mefuta ea profiles e ka aroloa ka tšepe e bōpehileng joaloka H, tšepe e bōpehileng joaloka I, joalo-joalo.
4. Tšepe e entsoeng;Sebetsa tšepe;Tšepe e kolobisitsoeng e chesang;Tšepe e batang.Tšepe e arotsoe ka sebopeho sa metallographic maemong a annealed: ① hypoeutectoid steel (ferrite+pearlite);② Eutectoid tšepe (pearlite);③ Pula ea tšepe e tsoang ho tšepe ea eutectic (pearlite+cementite);④ Lainitic tšepe (pearlite+cementite).
5. Litšepe tse batang: mofuta oa tšepe o entsoeng ka litšepe tse kobehang tse batang kapa litšepe.Lintlha tsa boleng bo phahameng: tšepe e chitja ea boleng bo holimo, tšepe ea lisekoere, tšepe e bataletseng, tšepe ea hexagonal, joalo-joalo b.Letlapa la tšepe;Thin steel plate: Letlapa la tšepe le botenya ba limilimithara tse 4 kapa ka tlase ho moo.Lipoleiti tsa tšepe tse mahareng le tse teteaneng: Lipoleiti tsa tšepe tse nang le botenya bo fetang limilimithara tse 4.
6. Nomoro e emela boleng ba ntlha ea lihlahisoa, mohlala, Q275 e emela ntlha ea lihlahisoa tsa 275Mpa.Haeba litlhaku A, B, C, le D li tšoauoa ka mor'a kereiti, e bontša hore boemo ba boleng ba tšepe bo fapane, 'me palo ea S le P e fokotseha ka tatellano, ha boleng ba tšepe bo ntse bo eketseha ka tatellano.
