当前,国际上普遍采用的球团生产技术主要有竖炉工艺和链簏机一回转窑工艺。为了大量使用低价细矿粉,从而降低球团生产成本,西门子金属技术公司新近开发出了一种创新型球团生产技术——环式制球技术(CPT)。当前,全球高炉炉料中球团用量都呈现逐步增加的趋势,各球团厂为了降低原料采购成本,更多地使用细矿粉,这样容易造成球团强度降低及生产率下降。此外,采用传统工艺路线生产球团,设备占地面积太大,导致一些受到场地限制的钢 At present, the pelletizing technology widely used in the world mainly includes the shaft furnace process and the rotary kiln process of the chain machine. In order to reduce the pellet production costs by using a large amount of low-cost fine ore powder, Siemens Metals Technologies has recently developed an innovative pelletizing technology called ring-and-ball system (CPT). Currently, the amount of pellets in the global blast furnace charge shows a gradual increase trend. In order to reduce the purchase cost of raw materials, pelletizing plants use more fine ore powder more, which easily leads to the decrease of pellet strength and the decrease of productivity. In addition, pellets are produced using traditional process routes and the equipment footprint is too large, resulting in some site restricted steel
