Distribution of reformed coke oven gas in a shaft furnace

Autor: Haiyan Zheng, Qiang-jian Gao, Jia-xin Yu, Xin Jiang, Lin Wang, Fengman Shen, Xiang Dongwen

Publikováno v: Journal of Iron and Steel Research International. 27:1382-1390

In recent years, the reformed coke oven gas (COG) was proposed to be used as reducing gas in a shaft furnace. A mathematical model of gas flow based on the reformed COG was built. The effects of the pressure ratio of reducing gas to cooling gas (k) o

Publikováno v: Journal of Iron and Steel Research International. 27:624-630

In recent years, more and more high Al2O3 iron ores were used in East Asia, especially in China, which increased the Al2O3 content in blast furnace (BF) slag and resulted in poor metallurgical properties of slag. Adding MgO-bearing flux is one of the

Effects of MgO additive on metallurgical properties of fluxed-pellet

Autor: Qiang-jian Gao, He Guo, Fengman Shen, Xin Jiang, Guan-gen Ding

Publikováno v: Journal of Central South University. 26:3238-3251

As a main charging burden of blast furnace (BF) ironmaking process, pellets play an important role in ironmaking process. However, compared with sinters, there are some inevitable disadvantages for traditional acid pellets, e.g., reduction swell, low

Fundamental mechanism of effects of MgO on sinter strength

Autor: Han Hongsong, Qiang-jian Gao, Haiyan Zheng, Xin Jiang, Fengman Shen, Chuan-guang Bi

Publikováno v: Journal of Iron and Steel Research International. 26:1171-1177

MgO-containing flux may have a series of effects on the quality of sinter and performances of the blast furnace. Thus, the fundamental mechanism of the effects of MgO on the sinter strength was investigated. Both the chemical reagent and industrial f

Combustion characteristics of unburned pulverized coal and its reaction kinetics with CO2

Autor: Xin Jiang, Qiang-jian Gao, Jia-long Yang, Jiaxin Li, Haiyan Zheng, Fengman Shen, Xiang Dongwen

Publikováno v: International Journal of Minerals, Metallurgy, and Materials. 26:811-821

The combustion characteristics of two kinds of unburned pulverized coal (UPC) made from bituminous coal and anthracite were investigated by thermogravimetric analysis under air. The reaction kinetics mechanisms between UPC and CO2 in an isofhermal ex
