Anthu ena omwe amachita zochitika zina (mwachitsanzo, akatswiri othandizira, oyendera alendo) amanyalanyaza chisankho chokha ngati mpeni. Chitsulo, chomwe chimapangidwira, chimasiyanasiyana mumagulu ake, zinthu zina zowonjezera zomwe zimapangidwa, kuuma. Choncho, ambiri ali ndi chidwi ndi funsoli: ndi chitsulo chanji chabwino kwa mpeni?
Zizindikiro za chitsulo kwa mipeni
Mphamvu ya mipeni imakhudzidwa mwachindunji ndi zizindikiro zotsatirazi:
- Kuuma kwa chitsulo kwa mipeni . Ikhoza kutchulidwa ngati luso la alloy kuti likhale lolimba kulimbana kapena kupukuta, zomwe zingakhale zovuta kwambiri. Monga malamulo, mpeni wa mpeni uli ndi kuuma kwa 40-60 HRC. Ndibwino kuti musankhe mpeni womwe udzakhala wolimba pakati pa 50-60 HRC.
- Mphamvu yachitsulo - mawu awa amasonyeza malire, opitirira kwambiri omwe amachititsa kusintha kapena ngakhale kuwonongeka kwa tsamba. Malingana ndi lingaliro ili, makhalidwe a mpeni, monga ductility ndi ubongo, amatsimikiziranso. Nkhani ya pulasitiki ikhoza kukhala yosavuta kusintha, kusintha maonekedwe ake, koma kusagwedezeka. Zinthu zofooka zidzawonongedwa ngakhale ndi deformation pang'ono.
- Valani kukana kwa chitsulo . Ndi mphamvu yokhala ndi mawonekedwe a tsamba limene likuwoneka kuti likutsutsana. Kuzivala kutsutsana kumagwirizana kwambiri ndi kuuma kwa chitsulo. Ndipamwamba kwambiri kuposa mpeni.
Ndi chitsulo chotani chomwe chiri bwino kugula mpeni?
Chitsulo chimakhala ndi chitsulo ndi mpweya, chomwe chingakhale chapamwamba, chamkati kapena chochepa. Kuphatikiza apo, zida zake zingaphatikizepo zowonjezera mankhwala - zingakhale chromium, molybdenum, vanadium, nickel, manganese, silicon.
Pofuna kusankha chomwe chili chabwino chogula mpeni, m'pofunika kuti mudziwe makhalidwe ake.
Mipeni yambiri imapangidwa kuchokera ku zitsulo zamkati. Lili ndi makhalidwe awa:
- bwino kusintha;
- mphamvu;
- kulemera kwakukulu;
- Kukhalapo kwa zinthu zina zoterezi monga manganese, chromium, silicon, nickel.
Kuipa kwa nkhaniyi kumaphatikizapo chizoloŵezi chachikulu cha kutupa.
Mitsuko ya zitsulo za masika imatha kutchedwa chilengedwe: pakati pawo pali khitchini, ndi alendo , ndi asilikali.
Chodziwika kwambiri ndi chitsulo cha laminated kwa mipeni. Kawirikawiri, mpeni woterewu umakhala ndi maziko, chifukwa chogwiritsidwa ntchito molimbika kwambiri pogwiritsa ntchito mpweya wa carbon, ndi kuyika mbali ziwiri zazitsulo, zowonjezereka kwambiri.
Chitsulo chachitsulo kwa mipeni
Zitsulo zazitsulo zimakhala ndi kukhalapo kwa chromium mwa iwo. Zowonjezeredwa kuti zowonjezera kukana kwa alloy, ndi mpeni wosaphimbidwa ndi dzimbiri. Koma pa nthawi imodzimodziyo, chromium imakhala yochepetsera mphamvu yachitsulo, kotero imaphatikizidwa ndi ndalama zina.
Mitundu yambiri yachitsulo ikugonjetsedwa ndi magulu atatuwa:
- Mitengo ya malade, yomwe imatsutsa kwambiri kutupa, imadziwikanso ndi bwino kuvala kutsutsana - ndi AUS6, 7Cr17MoV, 65x3, Sandvik 12C27.
- Madzi a mpeni amapangidwa ndi chitsulo, omwe amatha kutsutsa ndi kukhazikika - awa ndi ma AUS8, 440B, 95x18, Sandvik 19C27, Sandvik 13C26.
- Malasi omwe amadziwika bwino ndi kutsekeka kwa kutupa ndipo zitsulo zazikuluzikulu ndizosavala - zimaphatikizapo zitsulo 154CM / ATS-34, VG-10, AUS10, 440C.
Pambuyo pophunzira zaumwini zachitsulo kwa mipeni, mukhoza kusankha nokha zabwino.
