1553.全球焊材市场报告(2015-2019年)
[金属制品业,有色金属冶炼和压延加工业,金属制品、机械和设备修理业] [2015-10-06]
Welding is a fabrication process to agglutinate metals or thermoplastics using coalescence. The process is economical and it is an efficient method to fuse metal permanently. It finds application in a number of industries such as automotive, transportation, energy, construction, shipbuilding, mining equipment and heavy machinery, and aerospace and defense. The items used in this process are known as welding consumables, and can be broadly categorized as filler metals and flux. The metals that melt with the joining materials, and are consumed in the process are called filler metals. Flux is used to produce a gas shield around the weld pool that prevents oxidation of the hot metal.

1557.亚甲基蓝还原浸出低品位钴土矿
[有色金属冶炼和压延加工业] [2015-08-02]
采用亚甲基蓝作为还原剂,在硫酸体系中直接浸出低品位钴土矿,考察了亚甲基蓝浓度、硫酸浓度、反应温度、反应时间等对浸出率的影响。结果表明,在下述最优条件下,钴土矿中钴和锰的浸出率可同时达到99%以上:硫酸初始浓度1.6mol/L,亚甲基蓝初始浓度5g/L,反应温度95℃,浸出时间4h,液固比3∶1。

1558.钠硅渣石灰烧结法工艺探索研究
[有色金属冶炼和压延加工业] [2015-08-02]
对钠硅渣熟料配方及烧结温度进行了试验研究,并进行探索性工业溶出试验。结果表明,钠硅渣熟料应采用高钙比(C/S=2.1~2.2)配方,熟料烧结温度宜在1 200~1 270℃;由于熟料品位低,使得溶出液固含高、溶出二次反应剧烈,溶出浆液必需进行快速分离,以获得较好的溶出效果。

1559.湿法炼锌过程钙镁结晶机理研究
[有色金属冶炼和压延加工业] [2015-08-02]
通过模拟实际溶液与工业现场取样对比分析,探究湿法炼锌过程溶液中钙、镁的结晶机理。结果表明,溶液温度的降低是钙、镁结晶析出的主导因素;溶液中镁离子可诱导主金属元素锌的结晶析出;溶液中钙离子与镁离子在结晶析出过程中存在高盐分作用下的竞争反应,高温下溶液中钙离子易于镁离子优先结晶析出,低温下溶液中镁离子易于钙离子结晶析出。

1560.D201树脂吸附铁离子后洗脱研究
[有色金属冶炼和压延加工业] [2015-08-02]
选用盐酸和蒸馏水对D201强碱性阴离子交换树脂(Cl型)进行脱附再生,考查洗脱剂浓度、洗脱时间、洗脱温度对洗脱效果的影响。结果表明,25℃时,使用2倍树脂体积的1mol/L盐酸和3倍树脂体积的蒸馏水对吸附饱和的D201树脂(吸附含量14.4mg/g)进行洗脱,脱铁率达到98%。
