年均消耗循环水1256万吨,成本高达700万元。面对这样一组惊人的数据,西南铝熔铸厂以运营转型为抓手,开展降低循环水项目,该项目实施以来累计创效200余万元。熔铸厂作为西南铝的用水大户,每年的循环水量消耗巨大。经过认真分析,西南铝熔铸厂发现,循环水利用率偏低的原因在于铸锭结晶器结构老旧,于是,该厂从改进工装工具入手,用整体式结晶器技术替代老式的方锭结晶器结构,提高了循环水利用率,降低了冷却水的需求量。
The average annual consumption of circulating water of 12.56 million tons, the cost of up to 7 million yuan. In the face of such a staggering number of data, SWA Casting Plant started its operation transformation and started to reduce the circulating water project. Since its implementation, the project has accumulated more than 2 million yuan. Casting plant as a large water user of Southwest Aluminum, the annual recycled water consumption is huge. After careful analysis, Southwest Aluminum Foundry found that recycled water utilization is low due to the old ingot mold structure, so the plant from improving tooling to start with the overall mold technology to replace the old square ingot mold Structure, improve the utilization of recycled water, reducing the demand for cooling water.
