摘要
为了满足铁合金生产企业及消费铁合金的钢厂的需求,人们研究颗粒化金属的粒化工艺并发现了粒状铁合金的几个重要特性。粒化工艺是铁合金生产中一种工业化的、高产量的固化过程,替代了传统的、粗放型的浇铸、破碎和筛分工艺。该过程产生最少的细粉,具有最低的高价铁合金产品损耗。颗粒化的铁合金是一种均质的、纯净的产品,满足了标准日益严格的纯净钢材的生产需求。钢材制造商要求合金具有一定形状和尺寸,以适用于不同冶金工艺的自动化处理和使用。目前粒化的镍铁合金是市场上的标准样式。文章利用20多个装置实验,说明铁合金颗粒化的研究结果,并针对铬铁破碎和粒化两种工艺产生的筛下物进行对比。
To meet the needs from ferroalloy producers and the consuming steel makers,the GRANSHOT metal granulation process and the granulated ferroalloy have been found to have several important properties. The GRANSHOT process is an industrial and high capacity solidification process replacing the traditional and extensive casting,crushing and sieving operations in ferroalloy production. The process also has a minimum of fines and losses of the high cost ferroalloy product. Granulated ferroalloy is a homogenous and clean product which meets the increasingly stricter demand for cleaner steels. Steel makers requests alloys to have a shape and size which is suitable for automatic handling and use into any metallurgical processes. Today granulated ferronickel is the standard format for the market. This paper will present results from ferroalloy granulation,proven in over 20 installations,as well as a comparative study on the lower fines generation of a granulated vs. a crushed ferrochrome material.
