低合金熔煉的裝料原則？答：用開(kāi)底式裝料罐加料時(shí)，在料罐底部裝部分小料或鋼屑?jí)|爐底，其上裝大塊料和中塊料，上部裝小塊料及鋼屑等薄料，在料罐中對(duì)應(yīng)于爐子高溫區(qū)的位置裝大塊料和難熔的爐料；增碳用的電極碎塊應(yīng)裝在料罐的下部，以減少在熔化過(guò)程中熔煉損耗，保證配碳的準(zhǔn)確性。料罐應(yīng)力求裝的緊密，以利于導(dǎo)電和導(dǎo)熱。隨同爐料裝入的合金，應(yīng)避開(kāi)電弧區(qū)，以減少熔煉損耗。爐料應(yīng)裝的緊密，以利于導(dǎo)電和導(dǎo)熱。裝入金屬料以前，先往爐底和爐坡上加入爐料重量1%-2%的石灰，以保護(hù)爐底，并在熔化期中造渣脫磷。
