style="text-indent:25px">合金圓鋼的制作過程：轉(zhuǎn)爐煉鋼簡(jiǎn)介，從魚雷車運(yùn)來(lái)的鐵水經(jīng)過脫硫、擋渣等處理后即可倒入轉(zhuǎn)爐中作為主要爐料，另加10%以下的廢鋼。然后，向轉(zhuǎn)爐內(nèi)吹氧燃燒，鐵水中的過量碳被氧化并放出大量熱量，當(dāng)探頭測(cè)得達(dá)到預(yù)定的低碳含量時(shí)，即停止吹氧并出鋼。一般在鋼包中需進(jìn)行脫氧及調(diào)整成份操作;然后在鋼液表面拋上碳化稻殼防止鋼水被氧化，即可送往連鑄或模鑄工區(qū)。對(duì)要求高的鋼種可增加底吹氬、RH真空處理、噴粉處理(噴SI—CA粉及變性石灰)可以有效降低鋼中的氣體與夾雜，并有進(jìn)一步降碳及降硫的作用。</p><p style="text-indent:25px">圓鋼的韌性：在工作過程中，模具承受著沖擊載荷，為了減少在使用過程中的折斷、崩刃等形式的損壞，要求圓鋼具有一定的韌性。圓鋼的化學(xué)成分，晶粒度，純凈度，碳化物和夾雜物等的數(shù)量、形貌、尺寸大小及分布情況，以及圓鋼的熱處理制度和熱處理后得到的金相組織等因素都對(duì)鋼的韌性帶來(lái)很大的影響。特別是鋼的純凈度和熱加工變形情況對(duì)于其橫向韌性的影響更為明顯。鋼的韌性、強(qiáng)度和耐磨性往往是相互矛盾的。因此，要合理地選擇鋼的化學(xué)成分并且采用合理的精煉、熱加工和熱處理工藝，以使模具材料的耐磨性、強(qiáng)度和韌性達(dá)到極好的配合。合金圓鋼的耐蝕性隨含碳量的增加而降低。</p><div
