Mhando Uye Mamodheru esimbi, Uye Ndeapi Iwo Makuru Makuru Matatu eSimbi?

1,Ndedzipi mhando dzesimbi

1. 40Cr, 42CrMo, nezvimwewo: Inoreva alloy structural simbi, iyo ine yakanakisa yepamusoro-tembiricha simba uye kuneta kuramba, uye inowanzoshandiswa kugadzira zvakakosha zvikamu zvemichina mikuru.Iyo yepasi rose yakajairwa simbi modhi ASTM A3 ndeyekuAmerica yakajairwa kabhoni dhizaini simbi, ine zvine mwero michina zvivakwa uye inowanzoshandiswa mukugadzira zvakajairwa zvimiro zvemukati.

2. Mhando huru dzesimbi dzinosanganisira special carbon structural simbi, carbon tool simbi, carbon spring steel, alloy spring steel, alloy structural simbi, simbi inotakura bhora, alloy tool simbi, high-speed tool simbi, simbi isina tsvina. , simbi inodzivirira kupisa, pamwe chete nepamusoro-tembiricha alloys, precision alloys, uye electrothermal alloys.

3. E kukosha: 26 yemhando dzose uye avo vane a, 44 kune avo vane b, uye 24 kune avo vane c.Chikwata chehurefu chega chega chiri mumamirimita.Simbi kureba zviyero zvinoreva zvimiro zvekutanga zvemhando dzakasiyana dzesimbi, kusanganisira kureba, hupamhi, kureba, dhayamita, radius, dhayamita yemukati, dhayamita rekunze, uye ukobvu hwemadziro.

4. Simbi inowanzopatsanurwa muzvikamu zvina: profiles, marata, zvekuvakisa, uye pombi.Zvishandiso zveprofile uye mahwendefa zvinonyanya kuiswa seQ235B, Q345B, uye Q355B, nepo chinhu chikuru chekuvaka chiri HRB400E, uye zvinhu zvepombi zvakare zvakanyanya Q235B.

Iwo marudzi emaprofile anosanganisira H-yakaita simbi, I-shaped simbi, chiteshi simbi, uye angle simbi.

5. Simbi yakakosha: inoreva simbi yakakosha inoshandiswa muzvikamu zvakasiyana-siyana zvemaindasitiri, senge simbi yemotokari, simbi yemuchina wekurima, simbi yekubhururuka, simbi yekugadzira michina, simbi yekudziya yevira, simbi yemagetsi, welding waya, nezvimwewo. tsanangudzo dzakasiyana welded pombi zvigadzirwa zvakasiyanawo, kazhinji anoratidzwa nezita dhayamita.

2、 Nzira yekusiyanisa marudzi uye mhando dzesimbi

1. Maererano nekushandiswa kwakasiyana uye zvinodiwa, simbi inogona kugoverwa mumhando dzakasiyana-siyana uye mienzaniso.Simbi yeCarbon yakarongedzwa nemakemikari ekuumbwa: Simbi ine kabhoni yemukati pakati pe008% ne11%, inonyanya kushandiswa kugadzira mekiniki zvikamu, mavhiri, matiraki, nezvimwe.

2. Tsanangudzo yemhando yesimbi yekumiririra giredhi nzira muChina: 1. Carbon structural steel inoumbwa neQ + nhamba + yemhando yegiredhi chiratidzo + deoxygenation nzira chiratidzo.Simbi yaro yegiredhi inotaridzwa ne "Q", inomiririra goho resimbi, uye nhamba dzinotevera dzinomiririra kukosha kwegoho, muMPa.Semuenzaniso, Q235 inomiririra iyo goho poindi ( σ s) 23 MPa kabhoni structural simbi.

3. Simbi yakakamurwa kuva mhando ina: profiles, mahwendefa, zvokuvakisa, uye pombi.Pakati pazvo, maprofile uye mahwendefa anogona kuiswa muQ235B, Q345B, uye Q355B, nepo zvekuvakisa zviri HRB400E uye mapaipi ari Q235B.Mhando dzeprofile dzinogona kukamurwa kuita H-yakaita simbi, I-yakaita simbi, zvichingodaro.

4. Simbi yakagadzirwa;Cast steel;Kupisa kwakaputirwa simbi;Simbi inotonhorwa.Simbi yakarongedzwa nemetallographic chimiro mune annealed state: ① hypoeutectoid simbi (ferrite+pearlite);② Eutectoid simbi (pearlite);③ Kunaya kwesimbi kubva eutectic simbi (pearlite+cementite);④ Lainitic simbi (pearlite+cementite).

5. Cold form steel: imhando yesimbi inoumbwa nesimbi inotonhora inokotama kana mitsetse yesimbi.High quality profiles: Yemhando yepamusoro simbi, square simbi, flat simbi, hexagonal simbi, etc. b.Sheet metal;Simbi ndiro yakatetepa: Ndiro yesimbi ine ukobvu hwemamirimita mana kana pasi.Mahwendefa esimbi epakati uye akakora: Mahwendefa esimbi ane ukobvu hunodarika mamirimita mana.

6. Nhamba inomiririra kukosha kwegoho, semuenzaniso, Q275 inomiririra goho re275Mpa.Kana mabhii A, B, C, uye D akaiswa mushure megiredhi, zvinoratidza kuti chiyero chehutano chesimbi chakasiyana, uye huwandu hweS uye P hunoderera sequentially, asi hutano hwesimbi hunowedzera sequentially.
