Chithunzi cha ASTM A179ozizira kukokedwa seamless mpweya zitsulo chitoliroamagwiritsidwa ntchito m'magawo osiyanasiyana azitsulo zamapangidwe azitsulo, makamaka pambuyo pa dzimbiri lazitsulo zomizidwa mu 440 ~ 460.℃kusungunuka nthaka njira, kotero kuti zitsulo pamwamba Ufumuyo nthaka wosanjikiza, amene amasewera wotetezera cholinga.Iyi ndi njira yothandiza ya dzimbiri zachitsulo, kugwiritsa ntchito zinthu zazikulu ndi izi:

(1) ASTM A179 ozizira kukopeka opanda msokonezo opanga chitoliro ndi wandiweyani wandiweyani wosanjikiza nthaka yokutidwa ndi ozizira kukokedwa msokonezo chubu pamwamba, akhoza kupewa ozizira kukokedwa osasokonekera chubu masanjidwewo ndi kukhudzana ndi njira dzimbiri kuteteza masanjidwewo zitsulo ku dzimbiri.Mu ambiri mlengalenga, pamwamba pa nthaka wosanjikiza kupanga wosanjikiza wa woonda ndi wandiweyani okusayidi pamwamba, n'zovuta kupasuka m'madzi, kotero masanjidwewo zitsulo amachita zoteteza.Ngati zinc oxide ndi zigawo zina za mlengalenga zimatulutsa mchere wosasungunuka wa zinki, zotsutsana ndi kutu ndizofunika kwambiri.

(2) Ndi chitsulo - zinki aloyi wosanjikiza, kuphatikizapo wandiweyani, ndi wapadera odana ndi dzimbiri mu mlengalenga m'nyanja ndi mlengalenga mumlengalenga.

(3) ASTM A179 yozizira yokoka chitoliro chosasunthika chokhala ndi kukana kolimba chifukwa cha kuphatikiza kolimba, zinki - chitsulo miscible.

(4) Popeza nthaka imakhala ndi ductility yabwino, wosanjikiza wake wa aloyi ndi zitsulo zachitsulo zomwe zimagwirizanitsidwa ndi cholimba, kotero kuti zigawo zotentha zotentha zimatha kukhala ozizira, kugudubuza, kujambula, kupindika ndi kuumba kwina popanda kuwonongeka kwa zokutira.

(5) Hot-kuviika kanasonkhezereka structural chitsulo chitoliro, lofanana ndi annealing mankhwala, angathe bwino kusintha makina zitsulo masanjidwewo kuthetsa zitsulo kupanga kuwotcherera kupsyinjika, ndi yabwino dongosolo zitsulo kutembenukira.

(6) Pamwamba pa chitoliro chozizira chokokedwa chopanda msoko pambuyo pa malata otentha ndi owala komanso okongola.

(7) Koyera nthaka wosanjikiza ndi otentha kwambiri kanasonkhezereka wosanjikiza kanasonkhezereka wosanjikiza, chikhalidwe chake kwenikweni pafupi koyera nthaka, ndi ductility, choncho ndi wodzaza kusinthasintha.
