实现绿色特钢制造的思考

A Consideration in Realizing Environment-friendly Manufacturing of Special Steel

对于特殊钢企业的制造过程,“绿色”理念体现在高效的生产制造过程、物资的循环利用、废弃物的利用、绿色产品的开发与服务、能源与物资利用率的提高和有害物质的排放控制等6个主要方面。宝钢特殊钢分公司在这些方面做了一些工作。如绿色产品的开发上,开发了绿色环保型的含硫易切削钢替代含铅型易切削钢及49MnVS3、35Mn2S iV、F35MnVN等一批非调钢;在有害物质控制排放上应用了酸处理、粉尘控制等新技术,开发了绿色环保渣系列。同时还提出了思考,在提高能源与资源利用效率上可以开展以下工作:特殊钢金属料结构不断优化;天然气替代煤气后的加热效率基础性研究;扩大连铸品种,降低工序消耗;以轧代锻工艺和热送工艺。

In the manufacturing process of a special steel enterprise, ＂green＂ concept is reflected in six major aspects： efficient pmduction, material recycling, waste utilization, development of ＂green＂ products and related services, improvement of energy and material utilization rates and emission control of hazardous substances. Great progress has been made in these fields by Baosteel Special Steel Branch. in developing green products, sulfur-contal- ning and free-cuttlng steel, an environment-friendly product, has been developed to replace flee-cutting and lead-containing steel, and a series of other non-tempered steel products, such as 49MnVS3, 35Mn2SiV, F35MnVN, etc. In controlling emission of hazardous substances, new technologies, including acid treatment, dust control, etc. have been applied. And series of envlronment-friendly slag has been developed. In improvement of energy and material utilization rates, the following researches can be carried out ： constant optimization of material structure for special steel ; fundamental research on heating efficiency of natural gas after it replaces coal gas; development of new continuous casting products to reduce consumption on each procedure; replacing forging with rolling, and hot charging process.
