一、现状1984年我国地方小铁厂生产生铁297.5万吨,预计1985年可达330万吨以上。因此,小铁厂已成为地方工业所需钢铁的重要来源之一。但是大多数企业小高炉的原料准备采用的还是“平地吹”土烧结工艺,其主要缺点是: (1) 工人劳动强度大。生产中除采用少量机械外,主要是人工操作; (2) 严重污染环境。生产中无任何烟尘治理措施,劳动环境恶劣; (3) 燃耗高。每吨烧结矿平均能耗在120kg标准煤以上; (4) 成品率低、产品质量差。烧结矿
First, the status quo In 1984 China’s local ironworks pig iron production 2,975,000 tons, is expected in 1985 up to 3.3 million tons. As a result, small ironworks have become an important source of steel for the local industry. However, most of the small blast furnace raw material preparation is still used “flat ground” soil sintering process, the main drawback is: (1) workers labor-intensive. In addition to the production of a small amount of machinery, the main manual; (2) serious pollution of the environment. Production without any dust control measures, poor working conditions; (3) high fuel consumption. The average energy consumption per ton of sinter above 120kg standard coal; (4) low yield, poor product quality. Sinter
