How does coke and coal play into steel making? -

2016-6-22 · Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880’s, steel was produced using charcoal.

2018-1-31 · 1. Introduction. A sintering process not only consumes a large amount of fossil fuels, but also releases a great number of contaminants .Coke, as one of a raw material, is added into the raw mixture in the second proportioning phase of a sintering process so as to provide energy for burning to cause physical changes and chemical reactions.

A Data-Driven Model for Energy Consumption in the ...

One of the critical process steps involved in steelmaking is sintering, which converts iron-rich materials (e.g., fine-grained iron ore, mill scale, dust, and sludge) along with fuel (coke breeze and fine coal) and additives (e.g., limestone and dolomite) into a porous material suitable for adding to a blast furnace.

Non-coke smelting reduction of iron ores: Process ...

The scarcity of coking coals and the high cost entailed in minimizing the emissions from the coke-making process as well as the relative inflexibility of large production capacity of the conventional blast-furnace ironmaking are the main reasons for the development of non-coke smelting reduction processes with the economical and ecological compatibility.
