CRM developed a probe determining the raw material trajectories in bell-less top charging, by measuring the force generated by the material stream on a beam, in function of its position in the furnace. A prototype probe was tested on an industrial blast furnace during its first charging after a relining. These trials allowed the determination of both coke and sinter trajectories for the various chute angles. These results were validated by measurements carried out simultaneously by Irsid with painted bars.
CRM 开发了一种探头,通过测量物料流在横梁上产生的力,确定无料钟炉顶装料过程中的原料轨迹,并与原料在高炉中的位置相关联。原型探头在一座工业高炉上进行了测试,该高炉是在更换炉衬后进行首次装料的。通过这些试验,确定了焦
炭和烧结矿在不同溜槽角度下的运动轨迹。伊尔西德公司使用涂漆棒同时进行的测量验证了这些结果。
