高炉炉顶的钟式装料设备的缺点很多,如大小钟的制造,运输,安装,检修都很困难,使用过程中容易变形。若取消大钟、小钟,改用一个旋转溜槽向炉内布料,不仅从根本上免除了上述料钟式装料设备的缺点,而且能按冶炼需要将炉料分布于炉喉内的任意点,消除了炉料对炉墙的剧烈冲击。这种新型炉顶装料设备(简称旋转溜槽式)首先是由卢森堡的Wurth厂设计出来的。该设备1970型的试验模型见图1所示。它是一个生产模型,用来研究炉料从料斗通过溜槽向代表炉喉区的4扇形区布料的情况。它主要的特点是:有两个装有转阀和炉料流量控制阀的闭锁料斗,一个中心下料管,一个在布料时可调节斜度的溜 There are many shortcomings of the blast furnace top charging equipment, such as the size of the clock manufacturing, transportation, installation, maintenance are very difficult to use during deformation. If you cancel the clock, small bell, use a rotating chute cloth to the furnace, not only fundamentally eliminates the shortcomings of the chime-type charging equipment, but also according to the smelting needs of the charge distribution at any point within the throat, Eliminate the impact of the charge on the furnace wall. The new top charging device (rotary chute) was first designed by the Wurth plant in Luxembourg. The model of the 1970 model shown in Figure 1. It is a production model used to study the charge from the hopper through the chute to the 4 throat area representing the fabric of the throat area. Its main features are: There are two lock hoppers equipped with rotary valves and charge flow control valves, a central downpipe, an adjustable pitch slide
