Zida zogwiritsira ntchito
Ntchito Yopanga Zitsulo--Chitsulo chidzaphedwa.
Chitsulo chophedwa chimatanthauza kuwonjezera zinthu zina zochotsera poizoni monga silicon, aluminiyamu, ndi manganese panthawi yosungunuka kwa chitsulo.
Zowonjezera izi zimatha kuchitapo kanthu ndi mpweya womwe uli mu chitsulocho kuti zipange ma oxide olimba, motero zimachepetsa kuchuluka kwa mpweya womwe uli muchitsulocho ndikuletsa kupangika kwa ma inclusions oxidizing.
Giredi ya ASTM A210
ASTM A210 imapezeka m'magawo awiri:Giredi A-1 ndi Giredi C.
Njira Yopangira Chubu Yopanda Chitsulo cha ASTM A210
Mapaipi achitsulo ayenera kupangidwa ndi njira yopanda msoko ndipo ayenera kupangidwayotentha kwambiri or yozizira yomalizidwamonga momwe zafotokozedwera.
Kawirikawiri, mapaipi achitsulo okhala ndi mainchesi opitilira 30 mm amakhala otentha ndipo omwe ali ndi mainchesi ochepera kapena ofanana ndi 30 mm amakhala ozizira. Njira iyi yosiyanitsira si yokwanira koma ingagwiritsidwe ntchito ngati njira yachangu komanso yosavuta yodziwira njira yogwiritsira ntchito mapaipi achitsulo opanda msoko.
Kutentha Chithandizo
Kutenthetsa sikofunikira pa machubu omalizidwa ndi kutentha.
Machubu omalizidwa kuzizira ayenera kupatsidwa anneal yosafunikira, anneal yonse, kapena chithandizo chotenthetsera bwino pambuyo pa njira yomaliza yomalizira kuzizira.
