钢铁工业的能量回收,已受到许多国家的重视,然而还没有那个国家在这方面的努力比日本更有成效。钢铁工业是日本的主要能耗之一,占国家能源总耗量的15％,其中煤占58.8％,电力占25.1％和石油占16.1％。炼铁、炼钢、轧制和精整尽管能耗巨大,但也有效地产生了大量的再生能源——以气体和显热出现的付产品余热。这种再生能源的利用,已成为日本钢铁工业的主要任务。这里着重介绍炼焦、炼铁、炼钢和轧制等方面的热能回收情
Energy recovery in the steel industry has received the attention of many countries, yet no country in this area has been more effective than Japan in its efforts. The steel industry is one of Japan’s major energy sources, accounting for 15% of the country’s total energy consumption, of which coal accounts for 58.8%, electricity 25.1% and oil 16.1%. Ironmaking, steelmaking, rolling and finishing, despite their high energy consumption, have also produced large amounts of renewable energy efficiently - the residual heat of the products by gas and sensible heat. This use of renewable energy has become the major task of Japan’s steel industry. Here focuses on coking, ironmaking, steelmaking and rolling and other aspects of the heat recovery situation
