Carbon Materials - Shamokin Carbons

With the growth of mini-mill's increasing need for higher quality materials in the (EAF) Electric Arc Furnace anthracite coal has become the injection carbon of choice for the top EAF steel plants. Because scrap metal is the primary source of metal in the EAF there have been a limited variety of finished products a mini-mill could produce.

Use of PCI in blast furnaces, CCC/116 - ICSC

2006-10-1  Increasing steel demand and growing competition from scrap-based mini-mills is forcing blast furnace (BF)-based plants to improve their performance in order to reduce operating costs and, at the same time, increase productivity. One way to achieve this is by injecting pulverised coal directly into the BF. Injection of coal causes a number of changes within...

A wider range of coals can be used in PCI, including steam coal which has a lower carbon content than coking coal. This method has a number of advantages, including reducing overall costs and prolonging the life of existing coke batteries. Electric arc furnaces. The Electric arc furnace process, or mini-mill, does not involve iron-making.

2012-6-18  Pulverised Coal Injection. Pulverised Coal Injection (PCI) technology involves injecting coal directly into the blast furnace to provide the carbon for iron-making – displacing some of the coke required for the process. A wider range of coals can be used in PCI, including steam coal which has a lower carbon content than coking coal.

Steelmaking Process - an overview ScienceDirect Topics

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).
