铝合金扁锭铸造冷却水水质影响因素分析及控制措施

Analysis and Control Measures of Influencing Factors of Cooling Water Quality in Aluminum Alloy Slab Casting

针对某公司铝合金扁锭铸造冷却水水质较差、水质不稳定的问题,从冷却水系统运行方式、扁锭铸造工艺、生产方式、补水水质等方面分析冷却水水质差原因,并通过利用现有冷却水系统设备,改进设备运行方式,稳定生产量和铸造工艺,定期取样分析检测水质,探索补水规律等控制措施,使冷却水水质明显改善,符合铸造工艺要求,有效提高扁锭质量。

Targeted at the poor and unstable quality of the cooling water for aluminum alloy slab casting of one enterprise,the reasons for this problem were analyzed from such aspects as the operation mode of the cooling water system,slab casting process,production method,and makeup water quality.By improving the equipment operation mode,stabilizing the production capacity and casting process,regularly sampling,analyzing and testing the water quality,and exploring the water replenishment law,the cooling water quality was significantly improved,met the requirements of casting process,and effectively improved the quality of flat ingots.
