欧洲钢铁工业的环境保护已经达到了很高的水平。 2 0世纪 6 0年代初 ,保护环境一般认为只是局限于限制工业对人们的影响。现在 ,尤其是在罗马协议 (ClubofRome)的努力之下 ,环保的范围从节约资源延伸到整个自然环境的保护 ,而后产生了目前应用中的工业过程和产品生产周期。整体来说 ,保护环境的所有途径都被视为是未来平衡发展的先决条件。欧盟环境保护技术的情况可以德国为例 ,更准确地说是杜伊斯堡的蒂森克虏伯钢厂 (ThyssenKruppStahlAG) ,其粗钢产量约占德国总产量的 35 %。钢铁工业环境保护的重点仍然是维护空气质量 ,在此目的下 ,进行除尘处理。由烟囱处取样获得目前的除尘水平来看 ,今后的除尘主要是控制粉尘扩散和减少细小微粒的排放。钢铁工业环境保护的关键策略就是循环利用 ,它能起到与环境协调一致的作用 ,能够解决相关工艺中需要的大量的原料问题。德国的蒂森克虏伯钢厂 (ThyssenKruppStahlAG)现在炉渣的综合回收率水平已接近95 % ,其中冶金渣的回收利用率尤为突出。在德国 ,高炉渣利用率达到了 1 0 0 % ,同时炼钢渣的利用率也超过了90 % ,每吨粗钢的耗水量也控制在 1 0 0m3 的范围内。大量的努力不仅保证了有效的回收和再生利用工序 ,而且冷却水的利用也保证了新水的补充率降低到每吨粗钢
The environmental protection of the European steel industry has reached a very high level. In the early 1960s, protecting the environment was generally considered to be limited to limiting the impact of industry on people. Now, especially with the efforts of the Club of Rome, the scope of environmental protection extends from conservation of resources to protection of the entire natural environment, which then leads to the current industrial processes and product life cycles in use. Overall, all the ways to protect the environment are seen as a precondition for balanced development in the future. The case of the EU’s environmental protection technology can be exemplified by Germany, or more precisely ThyssenKrupp Stahl, Duisburg, whose crude steel production accounts for about 35% of Germany’s total output. The focus of the environmental protection of the steel industry is still to maintain the air quality, and for this purpose, to carry out dust removal treatment. Sampling from the chimney to obtain the current level of dust removal, dust removal in the future is mainly to control the spread of dust and reduce the emission of fine particles. The key strategy for environmental protection in the iron and steel industry is recycling, which can act in harmony with the environment and solve the large number of raw material issues that are required in the process. At ThyssenKrupp Stahlgas, Germany, the comprehensive slag recovery level is now close to 95%, with the recovery of metallurgical slag being particularly prominent. In Germany, the utilization rate of blast furnace slag reached 100%, and the utilization rate of steelmaking slag also exceeded 90%. The water consumption per ton of crude steel was also controlled within the range of 100m3. A great deal of effort not only ensures an efficient recovery and recycling process, but also the use of cooling water ensures that the replenishment rate of fresh water is reduced to about one tonne of crude steel
