為什么冷拔方鋼制造容易出現(xiàn)表面裂紋現(xiàn)象？1、裂紋假如是由于鋼中夾雜物未進(jìn)行處理而導(dǎo)致的。這就要選用合理的脫氧合金化工藝，嚴(yán)格控制鋼水含氧量，降低鋼水夾雜物的含量。2、假如裂紋是由外表折疊引起的。那么就要合理規(guī)劃孔型，消除成品前軋件的耳子;準(zhǔn)確規(guī)劃寬展，調(diào)輥槽方位，減輕或消除飛邊、刮傷等缺點(diǎn)。3、若是由皮下氣泡引起的裂紋。那就要注意全程保護(hù)澆筑進(jìn)程，防止鋼水二次氧化，削減氣泡發(fā)生，進(jìn)步鑄坯的純度;合理控制連鑄鋼水過(guò)熱度，選擇理化功能優(yōu)良的保護(hù)渣，采納均勻冷卻和二次弱冷卻，防止鑄坯外表出現(xiàn)裂紋。冷拔鋼是一種鋼材處理工藝。新鄉(xiāng)冷拔異型鋼廠(chǎng)</p><p
