style="text-indent:25px">(3)過熱金屬坯料由加熱溫度過高或高溫下保溫時間太長引起晶粒粗大的現(xiàn)象稱為過熱。過熱會使坯料塑性下降，鍛件的力學(xué)性能降低。為此，要嚴(yán)格控制加熱溫度，盡可能縮短高溫階段的保溫時間來預(yù)防過熱的產(chǎn)生。 (4)過燒金屬坯料加熱溫度超過始鍛溫度過多，使晶粒邊界出現(xiàn)氧化及熔化的現(xiàn)象稱為過燒。過燒后，材料的強(qiáng)度嚴(yán)重下降，塑性很差，一經(jīng)鍛打即破碎變成廢料，是無法挽救的。因此，要嚴(yán)格執(zhí)行正確的操作規(guī)范。 (5)裂紋大型鍛件加熱時，如果裝爐溫度過高或加熱速度過快，則鍛件心部與表層溫差過大，造成內(nèi)應(yīng)力過大，導(dǎo)致產(chǎn)生裂紋。因此，對大型鍛件加熱時，要防止裝爐溫度過高和加熱速度過快，一般應(yīng)采用防熱措施。</p><div style="width:100%;text-align: center;"><img style="max-width:
