style="text-indent:25px">康弘機械冷拔鋼在進行配料時需要遵從的準則：①堅持把理論配料(配料核算)和實踐經驗相結合。不管采納試算法仍是圖解法，理論上核算的配料數(shù)據(jù)，不能確定為配比，還要掌握中頻爐熔化過程中元素的變化規(guī)律。假如爐襯屬酸性材料，鐵液溫度15001，在31的加入量上只能取下限，而碳取下限。②掌握各種入爐金屬材料的化學成分和各元素燒損與復原規(guī)律。對回爐鐵(澆冒口、作廢鑄件)的分類堆放、編號記載，提出成分清晰的嚴格要求。爐內復原的元素在配料時減去，爐內燒損的元素在配料時補上。③冷拔鋼配猜中的合金元素以一次性配入為準則，除3以外其他配料時取中限，42CrMo圓鋼0、3等可在熔清扒渣后加入，在酸性爐中燒損較少。0、3在扒渣及孕育時還可以補充。就感應爐熔煉鑄鐵而言，遵從先增碳后加硅的準則。④對0、3含量的操控。0、3量首要來源于新生鐵，可以通過選擇爐料將0、8量操控在要求范圍內，所以要使新生鐵的0.06，04這樣在配料核算時，0、8量就可以不予考慮，因鑄件的技術要求不同。⑤爐的一切金屬材料均要求準確計量。</p><div
