A study was undertaken to investigate the way the quality of the iron-bearing materials and coke affects blast furnace performance. Laboratory tests are described which studied low temperature degradation, reducibility, and softening underload of the sinter and pellet material and reactivity of the coke.

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.

This statistic represents coal consumption of coke ovens and blast furnaces in the United Kingdom (UK) between 1970 and 2016, in thousand metric tons. The coal consumption of coke ovens and blast furnaces decreased significantly over this period, from 25.3 million metric tons of coal in 1970 to 3.2 million metric tons of coal in 2016.

As will be seen later, the drop in total energy consumption coincides with both a decrease in producer price and production indices according to the Federal Reserve Board (FRB) and the U.S. Bureau of Economic Analysis (BEA).
One of the most effective ways of the technical progress in the blast furnace manufacture is improvement of physical and chemical characteristics the iron ore materials and coke that allows to increase the smelting of pig-iron and to reduce the coke specific consumption without building of new blast furnaces and concentrating plants.

It follows that increasing blast temperature is an effective countermeasure to reduce the production of unburned char in the raceway of blast furnace, especially when the coals with high fuel ratio are blended.
