熱軋扁鋼的初始鍛造溫度應(yīng)理解為加熱爐中鋼或合金允許的比較大加熱溫度。在從爐子移除到坯件鍛造設(shè)備并開始鍛造之前，根據(jù)坯料尺寸，坯料輸送方式以及加熱爐和鍛造設(shè)備之間的距離，坯料具有幾十度的溫度下降。因此，鍛造開始時的溫度略低，一旦鍛造開始，鋼坯的溫度下降應(yīng)盡量減少。 </p> <p> 鋼超燃溫度低于100-150度的低熔點。C，過熱溫度比燃燒低溫約50℃，所以鍛鋼溫度應(yīng)低于熔點（或低于固相線溫度150-200℃的狀態(tài)圖）。此外，碳含量對鋼的鍛造的上限溫度具有**重要的影響。初始鍛造溫度隨碳含量的增加而降低。因此，起始溫度通常隨碳含量的增加而降低。 </p> <p> 鍛造前有熱軋扁鋼，加熱溫度太高或過熱造成的鍛造變形可能會發(fā)生破裂，同時過熱粗糧，但往往受到鍛造變形和變形均勻性限制嚴重過熱的影響鍛造變形不容易完全消除。因此，應(yīng)確定安全起動溫度以防止過熱。鍍鋅扁鋼批發(fā)，云南貿(mào)軒商貿(mào)有限公司。昆明質(zhì)量鍍鋅扁鋼經(jīng)銷商</p><p
