在京唐504m²带式焙烧机上进一步开展碱性球团生产工业试验，对生产的碱性球团矿进行取样化验，实现了碱性球团矿全铁品位能够维持在65%以上较高水平，硅含量2.6%左右，下一步工作可进一步降低硅含量，碱度1.1左右，达到预计目标。

The industrial test of alkaline pellet production was further carried out on Jingtang 504m² belt roaster, and the alkaline pellet was sampled and tested. The total iron grade of alkaline pellet can be maintained at a high level of more than 65%, and the silicon content is about 2.6%. In the next step, the silicon content can be further reduced, and the alkalinity is about 1.1, reaching the expected goal.
