rumwe ruzivo

Kupisa kurapwa kurapwa: kujairika, 910 ℃, mweya unotonhora.

Metrographigraphic dhizaini: Ferrite + Perlite.
Kupisa kurapwayesimbi makumi maviri uye inodzima kuomarara kwesimbi kwete. 20:
Kupisa kurapwa kwegumi neshanu:
1. Mushure mekushongedza machinji, basa rekushanda rakadzimwa seyakazara nekushambadzira kurapwa (920 ℃ yekudzvanya brine uye kunze kwemotokari denderedzwa, kugadzirisa kaleway.
2..
3. Kutakura uye kudzika, kuchema gomba remukati uye keyway.
Iyo inoyerera inoyerera ndeye yechipiri, yechitatu uye yakawanda.
● Kuendesa Nyika: Kuendesa mumamiriro ekurapa kwekupisa kana kurapa kwekushisa (kuyananiswa, kujairika kana kukwirira kwemamiriro ekushambadzira kuchiratidzirwa kuchiratidzirwa muchibvumirano. Kana isina kuratidzwa, iyo yekuendesa ichaitwa pasinaKupisa kurapwa.
