近二十年来,鉴于高炉工艺操作和基础理论研究的发展,高炉炼铁技术有了相当大的进步。例如在日本,十年前高炉平均容积仅为1000M~3,而在今天近5000M~3容积的高炉已经投产。这主要是通过改进机械装备、改进操作技术以及进行理论研究来实现的。然而,为了建造巨型高炉,在很多方面诸如电力机械、土建工程、结构和耐火材料等都采用了很多新技术。此外,检测技术的进步、控制和检修维护水平的提高也都与此有
In the past two decades, considerable progress has been made in blast furnace ironmaking technology in view of the development of blast furnace process operations and basic theoretical research. For example, in Japan, the average blast furnace capacity was only 1000M ~ 3 years ago, and today the blast furnace of about 5000M ~ 3 volume has been put into operation. This is mainly achieved by improving the machinery and equipment, improving operational skills, and conducting theoretical research. However, in order to build giant blast furnaces, many new technologies have been adopted in many aspects such as electric machinery, civil engineering, structures and refractories. In addition, testing technology advances, control and maintenance of the level of improvement are also with this
