Chii chinonzi oksijeni yemukati yesimbi yakanyungudutswa nechoto chekunyungudutsa?

Okisijeni yemukati musimbi yakanyungudutswa yakanyungudutswa mucupola inowanzo 0.004 ~ 0.006% (chikamu chezhinji, zvakafanana zvinoshanda kune zvinotevera), uye iyo oksijeni iri musimbi yakanyungudutswa yakanyungudutswa mu kudonhedzwa kunyorera vira kazhinji inenge 0.002%, dzimwe nguva kunyange yakaderera. Kazhinji kutaura, iyo yakaderera oksijeni yemukati musimbi yakanyungudutswa inobatsira kuvandudza iyo metallurgical mhando yekukanda. Zvisinei, kana iyo okisijeni yemukati musimbi yakanyungudutswa yakaderera (0.001% kana yakaderera), haibatsiri pakuumbwa kwekristaro nuclei panguva inoculation , Zvinokonzera kugadzirwa kwe supercooled graphite (Rudzi D), kunyange kana huwandu hweinoculant. inowedzerwa inowedzerwa, iyo inoculation mhedzisiro haina kunaka.
