摘要
由于结晶器的结构及高镁铝合金的特性,其在生产过程中易出现大面拉裂、角部拉裂、翘曲漏铝、塌陷裂纹、过渡期裂纹等缺陷。通过优化结晶器角部维护工艺,并针对铸造工艺参数开展试验探索,在铝熔体处理、石墨板清洁与锁紧、隅角润滑及冷却与液位控制等多方面实施综合改进,有效缓解了可调石墨结晶器在角部密封与石墨板匹配方面的硬件限制,成功实现高镁铝合金扁锭的稳定性生产。
Due to the structure of the mold and the characteristics of high-magnesium aluminium alloys,defects such as large surface cracking,corner cracking,warping and aluminium leakage,collapse cracking,and transient cracking are prone to occur during the pro-duction process.By optimizing the maintenance process of the mold corners and conducting experimental exploration on casting pro-cess parameters,comprehensive improvements were implemented in multiple aspects including aluminium melt treatment,cleaning and locking of graphite plates,corner lubrication and cooling,and liquid level control.This effectively alleviated the hardware limita-tions in the corner sealing and graphite plate matching of adjustable graphite crystallizers,successfully achieving stable production of high-magnesium aluminium alloy slabs.
