料层高度 【厚度】(The sinter machine can now be operated at a higher speed from 1. 64 m / min at a bed depth of 584mm to 2. 0 m / min at a bed depth of about 550mm. 现在烧结机可以以较高的速度运行：由料层厚度 584mm 、机速 1. 64m/min 到料层厚度约 550mm 、机速 2. 0m/min。)
起泡流态化床(This ironmaking process uses a circulating fluidized bed preheater and a 2-stage reactor for the reduction of iron ore fines： the first stage is a circulating fluidized bed, and the second stage a bubbling fluidized bed. 这一炼铁法使用一个循环流态化床预热器和一个二级铁矿粉还原反应器。该反应器一级是一个循环流态化床，二级是一个起泡流态化床。)
