This work represents an extended abstract of a study presented at the PRES 2016 conference. Despite the fact that alternative processes such as Corex® and Finex® have already been established on industrial scale, the blast furnace route continues to be the most important process used to produce pig iron. Due to its …
The blast furnace-converter process still plays a dominant role in China's iron and steel industry, which consumes a lot of coke and releases 1.8 t/ton-2.2 t/ton of CO 2. Therefore, the transformation of energy conservation and emission reduction are very critical for the iron and steel industry with huge output and energy consumption.
The global warming promotes the steel industry to replace part of coke by injecting hydrogen-rich fuel into the blast furnace to reduce CO2 emissions and energy consumption. In this paper, the injected hydrogen-rich fuels and effects of hydrogen-rich smelting on burden reduction and property evolution were introduced, and the hot …
The ladle furnace (LF) is widely used in the secondary steelmaking process in particular for the de-sulfurization, alloying, and reheating of liquid steel prior to the casting process. The Effective Equilibrium Reaction Zone model using the FactSage macro processing code was applied to develop a kinetic LF process model. The slag/metal …

The blast furnace ironmaking process generates large amounts of gaseous emissions and solid wastes from its routine operation every year. As the typical solid waste, the blast furnace dust (BFD) can be recycled as a raw material with its contained valuable contents of iron oxide and carbon [].Recovering these BFD has the benefits for both the …
However, another important vessel used in ironmaking is the Blast Furnace Trough (BFT) or main trough, a trench-like receptacle lined with castable refractories wherein the products of the blast furnace –molten hot metal and slag– are collected after their extraction from the BF and separated by density difference.
The blast furnace uses iron ore as the iron-bearing raw materials, coke and pulverised coal as reducing agents and lime or limestone as fluxing agents. The main objective of blast furnace …
