Konstriksyon machin asye mete asye jete pati Distribisyon

(1) Kontni an souf ak lòt eleman tras nan fè ductile fè kochon fè pa ta dwe twò wo . Si kontni an nan eleman tras tankou souf nan fè kochon se twò wo, plis modulateur oswa modulateur ak pi wo kontni sou latè ki nesesè, ki ogmante pri a nan modilatè .}

(2) Stability of nodular casting modularization treatment. Spheroidizing process is the key process in nodular cast iron production. Only when the nodularization process is stable, the quality of the casting can be stable. Depending on the different products and the sulfur content of hot metal, how many nodulating agents and inoculants need to be Te ajoute . deskripsyon travay yo dwe byen ekri ak entèdi swiv .
(3) Evite lontan tann . vide imedyatman apre spheroidization . Apre yon tan, yo pral mayezyòm ki rete a ap boule deyò epi yo inokulasyon a pral mwens efikas .
(4) Avoid excessive residual magnesium content. Higher residual magnesium content will increase the tendency of casting shrinkage. The residual magnesium content of ordinary ductile iron should be controlled at 0.035% ~ 0.045%, and the residual magnesium content of high nickel ductile iron should be controlled at 0.06% ~ 0.07%.
