rumwe ruzivo

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

Metrographigraphic dhizaini: Ferrite + Perlite.
Kupisa kurapwayesimbi makumi maviri uye inodzima kuomarara kwesimbi kwete. 20:
Kupisa kurapwa kwegumi neshanu:
1. Mushure mekunyora machinji, basa rekushanda rakadzurwa seyakazara nekupfeka kurapwa (920 ℃ yekukasira mari ye30-5
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.
