Chiwanikwa simbi

Pakusarudza zvinhu nokuda kugadzirwa nesimbi zvigadzirwa unhu wandei kuonekwa, kusanganisira modulus kuti Rigidity. Izvi STRUCTURAL hanya indekisi kunobva chete pamusoro pemhando mashoko iro simba zvinhu - stringers, mapuranga, flat ndiro, etc.

The soro modulus pamusoro Rigidity ndiyo simbi, izvo zvinozoita ndiko mhando mbiri yavo makemikari anoumba. Chekutanga, ichi chiwanikwa simbi, izvo zvakananga akawedzera alloying zvinhu kuwana chero ehupfumi zvakakodzera.

Huru zvinhu kuti kupesvedzera ehupfumi hwendarira - ndiko kabhoni, nesilicon uye manganese. Carbon apo kuwedzera ayo kugutsikana kunoita simbi simba uye zvakasimba, apo nokuderedza ductility kwayo. Nesilicon chinotarisirwa kuva deoxidizing mumiriri, asi kana kwayo kugutsikana kunopfuura imwe muzana zvikuru kuipa kuti weldability kwakaita sesimbi: asi weld iri haungatani kuputsika. A ane chinhu sezvo manganese anovandudza chando brittleness uye kusimba kwakaita sesimbi, uyewo kuva deoxidizer akanaka.

Kazhinji, kuwedzera simbi uye kabhoni, inowedzerwa kuroorwa zvinoriumba chero, saka yakapambadzirwa simbi semhosva yakakura-chinoumba matatu, mana chazvo, uye zvichingodaro. D. Apo neapo nayo zvichisiyana kuti musoro alloying chinhu, akadai chromium, chromium-nickel, etc. hromonikelmolibdenovaya

Chiwanikwa simbi ine zvinopfuura chimwe muzana chromium kana nickel. Kana aripo kupfuura 0.5% kubva vanadium, titanium, molybdenum, niobium, senitrogen, mhangura, nezvimwewo, It runoonekwa izvi chiwanikwa zvinhu.

Zvichienderana nokuwanda akawedzera zvinoriumba, chiwanikwa hwendarira akakamurwa zvinotevera subclasses:

- mukuru-chiwanikwa simbi, sezvamakaropafadzwa zvachose zviri alloying zvinhu idukusa gumi muzana;

- srednelegirovannoj - hapana anopfuura masere muzana;

- yakaderera-yakapambadzirwa simbi, umo mumwe chete chaikosha ari akawedzera pamwe zviri yokumusoro panogumira kwete anodarika maviri muzana.

Kazhinji, asi alloying zvinhu kwazvo mutengo simbi, kunyanya sezvo mamwe masangano anowedzerwa mavari ndivo wakareruka simbi anodhura. Saizvozvowo, kuwedzera hwavo simbi anofanira kunyatsoongorora makateyiwa.

Yakapambadzirwa simbi ane zvinotevera mavanga: zviri digits maviri okutanga anoratidza kabhoni kugutsikana (hundredths rimwe muzana), tsamba anoratidza conditionally akawedzera alloying chaikosha digit vanovatevera - zviri chinhu ichi chive chikamu. Tsamba "A", inomira pakupera kupenda zvinoreva, kuti yepamusoro simbi ine pasi zviri phosphorus nesarufa.

Chimwe kusiyana makemikari anoumba simbi - kabhoni. Its nokuda nyore uye cheapness okuwana kuwedzera kushandiswa maindasitiri zhinji.

Mumwe akaronga kushandiswa simbi iri kushandiswa kwayo kugadzirwa kuyera uye vakatema maturusi, muchina zvikamu, anofa waitonhora uye kupisa deformation.

Danho simbi uye chiwanikwa mhosva, uye carbon, uye zvichienderana nemitemo kudzorwa mueni, nerimwe chaiyo simbi zvigadzirwa havafaniri kushandisa simbi kuva yakananga makemikari anoumba.

. Somuenzaniso, nokuti zvomusejari maturusi drills, chezero, sando, screwdrivers, masaha, hobs, etc. akashandisa simbi chaiyo muchikwata - mukuru-chiwanikwa, mukuru-nokukurumidza. Chine yakakwirira zvakaoma, kupisa kuzvidzivirira uye abrasion nemishonga. Izvi nedzimwe nzvimbo dziri vakawana nokuwedzera chinokosha alloying pamwe tungsten carbide, uyewo yakaoma nokupisa kurapwa.

Nokuti sando, kupisa nokutonhora, ikafa, achitanga uye unto. Used simbi mamakisi akadai H6VF, 9X, 5HNM etc.
