高炉正常的冶炼需要一定比例的物料,为保证顺利产出合格生铁,必须对入炉物料比例进行准确控制。目前我国中小高炉原料的称量有机械秤量和电子秤称量两种方法,这两种方法各有利弊。某厂四座100米~3高炉全部采用机械秤称量,几年来,在物料称量和皮带上料等方面积累了一套经验,正在改建中的220米~3高炉也决定采用机械秤称量。 220米~3高炉称量系统示于图1,其工艺流程如下:来自90米~3架空料仓的物料,通过闸门流到振动筛上。振料时振动筛启动,合格料振入称量漏斗,而粉料落入粉料漏斗。当合格料达到要求量时,磅秤内的限位开关发出停振信号并使振动筛停振。当需要
The blast furnace normal smelting need a certain percentage of the material, in order to ensure the smooth production of qualified pig iron, the proportion of material into the furnace must be accurately controlled. At present, the weighing of medium and small blast furnace raw materials weighed in both mechanical weighing and electronic scales are two methods, both advantages and disadvantages of these two methods. A factory four 100 meters to 3 blast furnaces are all weighed using mechanical scales, the past few years, in the material weighing and belt material has accumulated a set of experience is being rebuilt in the 220 m ~ 3 blast furnace also decided to use mechanical weighing . 220 m ~ 3 blast furnace weighing system shown in Figure 1, the process is as follows: 90 m ~ 3 empty silo material flow through the gate to the shaker. When the vibrating material vibrates, the qualified material vibrates into the measuring hopper while the powder material falls into the powder hopper. When the qualified material reaches the required amount, the limit switch in the scale sends out the stop signal and stops the vibrating screen. When needed
