Australian limonite is widely used all over the world,known with the properties of high assimilation ability and low bonding strength.Although measures such as quasi-particle design and densification
Assimilation characteristic reflecting the beginning formation temperature of liquid phase plays important role on the formation and flow of liquid phase,and strength of sinter body in the sintering p
Characteristics of the gas-solid reduction reaction between iron ore sinter and CO gas at 1 273 K were studied with Thermal-Gravity analyzer.The samples used in current study are industrial iron ore s
During sintering process,the formation and fluidity of the liquid phase on sinter quality plays a crucial role in determining quality of sinter ore,and as an important component,Mgo affects liquidus o
通过实验探索用国内高品位粉矿实现钒钛烧结提高铁份与降低SiO2的技术思路.实验结果表明,在品位提高与SiO2下降的情况下,烧结各项指标下降;通过提高碱度、用活性灰代替生石灰、添加硼化物、精矿预制粒、燃料分加、熔剂分加、澳矿分加、提高料层厚度等措施,在SiO2降到4.68％的条件下,均起到了强化低硅烧结的作用,各项技术指标均有改善.采用均匀设计方法,通过建模寻优参数最优组合为“生石灰配比8％,焦粉4
With on-site hoisting pallet of sintering material to carry out multi regional research,the reason of decline in sinter quality in deep sintering bed and high ratio imported ore of Jingtang was discov
烧结过程的稳定,对于高炉生产有着非常重要的作用，结合宝钢烧结生产的实际经验,运用六西格玛方法分析出影响烧结过程稳定性的因素,按西格玛水平,负效益、时间等因子进行权重打分筛选,找出两个重要的可控因素.根据宝钢高炉、烧结生产和搭配的实际特点,于2012年9月17日至2012年11月5日在宝钢1、2DL上进行高炉槽下烧结粉配比、三期匀矿使用模式试验.在原燃料外部条件未出现较大变化的背景下,通过烧结粉和三
Iron ore sintering process is a major supplier of the agglomerate burden to the blast furnace.The heat source of the process is mainly coke and therefore it emits a certain amount of C02.Because of a
Making full use of solid waste of steel is significant for energy-saving emission reduction,development of low-carbon production and circulation economy.Based on studying properties of various industr
An ideal coal blend to produce coke must have an appropriate maceral composition ( vitrinite,exinite and inertite) and to be in a particular range of carbonization degree or rank.This is because these
