炉料的合理分布是使高炉获得更好技术经济指标的重要手段之一,多年来一直受到人们的注意。自高炉大型化的趋势出现以后,人们研究的重点有所变化,侧重于解决大炉喉直径的中心布料问题,在设备结构上动了不少脑筋,并取得了突破,活动炉喉及无钟的溜槽布料就是出色的代表。然而对双钟装置布料规律的研究,就显得非常不够。同我国一样,苏联绝大多数高炉(包括2000～3000米~3级的)都是采用钟斗结构。虽然这些设备现在看起来已不那么先进,但鉴于改造这些设备一要时间,二要投资,并
The reasonable distribution of charge is one of the important means to get better technical and economic indexes of blast furnace and has been paid attention by people for many years. Since the appearance of the large-scale blast furnace, the focus of research has changed. The focus has been placed on solving the problem of the center cloth diameter of large laryngeal throat, moving a lot of brains in equipment structure and making breakthroughs. The chute cloth is an excellent representative. However, the research on the law of double-bell device cloth is not enough. As in our country, the vast majority of the Soviet blast furnaces (including 2000-3000 m 3) use bell-and-bell structures. Although these devices do not look so advanced now, given the time it takes to retrofit these devices, they have to invest and
