Uhlolojikelele lwenqubo yokucisha imvamisa ephezulu yokucisha ukwelashwa kokushisa kwemibese yokusika indwangu kagesi

Ummese wokusika wendwangu kagesi ukushisa okuphathwa ngomshini wokucisha imvamisa ephezulu. Ngemva kokushisa ngaphambi kokwelashwa kokushisa ku-550 ° C, kudluliselwa ku-860-880 ° C ukuze kushiswe kabusha ukwelashwa kokushisa. Izinga lokushisa lokushisa liyahlukahluka kuye ngamabanga ensimbi ahlukene. 1250-1260 ° C, 1190-1200 ° C, 1200-1210 ° C, 1150-1160 ° C, ngokulandelana. Usayizi wokusanhlamvu ulawulwa kumabanga ayi-10.2-11. Ekugcineni, ukwelashwa okushisa okushisa ku-550-560 ° C kuyenziwa.

Hlola ubulukhuni ngemva kokushisa, uma bungaphezu kuka-64HRC, kufanele bunyuswe bufinyelele ku-580 ℃ lokushisa. Hlola ubuqotho ngamunye ngamunye. Uma ukubekezelelana kweqiwe, qhubeka ubamba futhi uthukuthele, kodwa ukushisa ngokweqile akuvunyelwe.
