铸造生产过程中的废弃物循环再利用

Recycle and Reutilization of Foundry Production Wastes

以铁合金铸件生产为例,详细分析了铁合金铸件生产过程中产生的废砂、废渣、粉尘和废气等废弃物的由来,以及其对环境的严重影响;认为铸造企业新建或技术改造时就必须同时考虑废弃物的综合利用,并指出此项工作应该从改造方案设计、采用先进设备、采用清洁生产工艺和采用铸造废弃物资源化处理新技术等六个方面进行;最后,介绍了一汽铸造有限公司对这些废弃物所进行的循环再利用经验。

Taking ferroalloy casting production as example, the source of the wastes such as sand, slag, dust, exhaust gas and so on, and their harmful influence on environment was analyzed in details. It was believed that it is necessary to consider the comprehensive utilization of the wastes during building a new foundry or tech-reformation of a foundry, and it was pointed out that this job should be carried out by improving project design, adopting advanced equipment, adopting clean production processes, and adopting new treating technique of wastes resourcization. At last, the experience of FAW Foundry Co. Ltd., in recycling and reutilizing above mentioned wastes was introduced.
