Kuve nechokwadi chekuti L245pipelinesimbi pombi ine yakakwirira kuneta simba, compressive simba, pamusoro kuoma, uye refu upenyu basa, siyana asiri simbi inclusions akadai oxide inclusions, sulfide inclusions, uye pfungwa inclusions musimbi zvinofanira kunyatsodzorwa Mukati siyana;iyo inhomogeneity yemhando dzakasiyana-siyana musimbi (senge carbide liquefaction, strip carbide, band carbide, uye network carbide, nezvimwewo) inofanira kudzorwa mukati meyero.

Ukobvu hwedecarbonized layer pamusoro pesimbi yakapedzwa inotakura mushure mekupisa kupisa kunofanira kuderedzwa;iyo macroscopic yakaderera-magnification chimiro chesimbi inofanira kunge yakasununguka.Pakati inorasikirwa, uye nhanho yekuparadzanisa inofanira kuva duku.Subcutaneous bubbles, shrinkage maburi, Inclusions, uye makatsemuka.Iyo annealed simbi inodiwa kuti ive neyunifomu uye yakanaka spherical pearlite chimiro.

1. Pamusoro pezvinodiwa

Kuti ive nechokwadi chekuti pamusoro pekutakura hachina kukanganisa, pamusoro pechigadzirwa chesimbi chinotakura chinofanirwa kuve chakatsetseka uye chisina kuremara senge makatsemuka, mavanga, kupeta, gomba, uye mavanga.

2. Saizi zvinodiwa

Mukupedzisa kubereka simbi, kunyatsocheka kucheka zvinhu zvakasvibirira uye kuaisa muchikamu chinodiwa saizi, iyo dimensional kurongeka kweiyo inotakura simbi chigadzirwa inodiwawo zvakanyanya, uye chimiro chechigadzirwa chakapedzwa chinodiwawo kuti ive yakatwasuka.
