Kuita kuti peji iite seine chiremera, zvinobatsira kuratidza maitiro chaiwo. Nzira yemazuva ese kune aya -mabhawa ekutenderera akasimba ndeaya anotevera:

a) Kugadzira simbi uye kwechipiri kunatsa
Simbi inonyungudutswa muBOF kana EAF, yozobatwa muLF/VD kubvisa sarufa nephosphorus uye kugadzirisa alloy zvirimo chaizvo. Apa ndipo panowedzerwa micro-alloying elements seV, Ti neB. Low P uye S muMTC yako (0.015–0.017% P, 0.003–0.004% S) ndiwo chaiwo mhedzisiro yedanho iri - zvinovandudza kusimba uye kusimba.

b) Kukanda uye kugadzirira billet
Iyo yakanatswa simbi inokandwa mumabhiriji akakodzera kukungurukira round bar. Yakachena mabheti ane yakaderera inosanganisirwa zvemukati akakosha kuti upfuure bend / rebend uye bvunzo dzekukanganisa dzinoonekwa pachitupa chako.

c) Kupisa kutenderedza bara
Mabhiridha anodzoserwa uye akakungurutswa pamagetsi ebhari kusvika kudhayamita yekupedzisira (semuenzaniso, 27 mm). Rolling inodzorwa kuti iwane yakanaka yemhando yepamusoro, kutwasanuka uye dimensional kushivirira. Mabhawa anochekwa kusvika pakureba kwekutengesa, kazhinji 6 m.

d) Kurapa kwekupisa (kudzikamisa kana kudzima + kupisa)
Kuti usvike pamagetsi anoratidzwa pachitupa - tensile 950-960 MPa, goho rinenge 905-915 MPa, simba rekuita pa -20 dhigirii kutenderera 100-110 J - mbariro hadzisiyiwe "sezvinopisa zvakakungurutswa". Iwo akajairwa kana, kazhinji kune iyi nhanho yesimba,kudzimwa uye kushatirwa (Q&T).

Quenchinginopa yakaoma martensitic / bainitic chimiro.

Temperingpa tembiricha chaiyo inodzoreredza ductility, inosimudza kukanganisa kuoma, uye inodzikamisa iyo microstructure.
Danho iri ndiro rinoita kuti simba rikwire asi richiramba richirebesa kureba kuri pa13–14% uye kuderedza nzvimbo iri pamusoro pe50%.

e) Kutwasanudza, kucheka nekumaka
Mushure mekupisa kupisa mazariro akatwasanudzwa, akachekwa kusvika 6 m (kana mamwe marefu akarairwa), akasungwa uye akaiswa chiratidzo nenhamba dzekupisa.

f) Kuedzwa uye certification
