Blog: Is it time for China to switch to electric arc

In 2017, China's steel scrap exports suddenly surged to reach 2.3 Mt, which triggered a debate over whether or not China should build more electric arc furnace (EAF) plants to make use of its increasing domestic steel scrap. Today, EAF technology represents around 6.5% of China's steel production, compared to around 45% elsewhere in the world. Get price

Operation Trial of Hydrogenous Gas Injection of COURSE50

The main objectives of experimental blast furnace trial are to investigate and evaluate the potential in replacing coke and coal as reducing agents in the blast furnace with high H2 containing gas as COG or reformed COG, and also effects of hot top gas injection on temperature of upper part of the blast furnace and on sinter disintegration. 2.

Furthermore, its reducibility at 0.87%/min is within the acceptable range as a natural material feed for blast furnace and direct reduction furnaces. Also, the energy requirement for heating the ore to 1100#xb0;C was found to be higher in the samples containing a wider size range of irregular grains and the largest contaminations. Get price

The end of the blast furnace era?: Ironmaking

This paper explores the underlying drivers of steel production to predict the fate of the blast furnace as a steelmaking route. Steel production is driven by demand for stocks of steel products and increases in steel stocks are driven by population growth and economic development. However, per-capita steel stocks are expected to saturate with economic development leading to the long-term Get price
