苏联专利368318号介绍一种球团矿的生产方法。为了提高固体燃料的反应性能和设备能力,使用含二氧化钠百分之八至十二的水玻璃作为固化剂。粘结剂与铬铁渣混合加入料内,占精矿重量的百分之五至九。铁精矿先与水玻璃和铬铁渣混合,并用振动给料器将其送入反应器内,在摄氏六百至七百度下在沸腾层内预先造球。水玻璃由于含有二氧化钠,所以提高了固体燃料的反应性。加入碱性化合剂对固体燃料层间构造有很大影响,增
Soviet Patent 368318 describes a pellet production method. In order to improve the reactivity and equipment capabilities of solid fuels, sodium silicate containing 8 to 12 percent sodium dioxide is used as a curing agent. Binder and ferrochromium mixed into the material, accounting for five to nine percent by weight concentrate. The iron concentrate is first mixed with water glass and ferrochromium slag and fed into the reactor with a vibrating feeder to pelletize in the boiling layer at 600-700 degrees Celsius. Water glass because of containing sodium dioxide, so improve the solid fuel reactivity. The addition of a basic chemical compound has a significant effect on the inter layer structure of the solid fuel
