Lime for Making Steel - Carmeuse Lime & Stone

High quality dolomitic quicklime also helps steelmakers maintain the refractory life of their furnaces and control energy costs in the EAF through the foamy slag process. Lime plays a key role in fine tuning steel chemistry, lowering oxygen content, removal of impurities such as sulfur and reduction in inclusions trapped by the.

Blast furnace | metallurgy | Britannica

Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as line. Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace; an intermediate zone called a bosh between.

Blast Furnace - PracticalStudent

The Iron Ore, Coke and Line, (the Charge), is conveyed to the top of the Furnace. 2. The Charge is stored in Bells until the timing is right for the charge to be dropped into the Furnace. 3. Hot air is then blown through pipes called Tuyeres, to fire the mixture. 4. The Coke burns to increase the temperature in the Furnace.

Iron & steel - British Lime Association (BLA) part of the Mineral .

The impurities are removed when the iron is eventually melted and purified to produce steel, normally in an electric arc furnace. Thus the main slag former in iron making is line, or dolomite rather than lime/dolomitic lime. There are however some smaller uses of lime in ironmaking: Iron ores are usually purchased as.

The Blast Furnace - ThePotteries

The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and line are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to.

Studies of the efficiency of granulated blast furnace slag and .

A consequence of this is ... optimised for blast-furnace operations, the primary function being to produce iron with consistent properties.

Blast Furnace

May 3, 2010 . The iron making blast furnace itself is built in the form of a tall chimney-like structure lined with refractory brick. Coke, line flux, and iron ore (iron oxide) are charged into the top of the furnace in a precise filling order which helps control gas flow and the chemical reactions inside the furnace.

The specific objectives are to determine SO2 reductions as a function of line/trona injection rate and the upper furnace injection location, determine SO2 reductions in the CTF when line is blended with the pulverized coal, and determine slagging effects of the various line/trona injection strategies. The tests.

The Kinetics of Calcination of High Calcium Line

In this work, the kinetic studies of the calcination of Ukpilla line (a local high calcium line resource) was studied. . which suggests that diffusion of CO2 through the thin layer of active lime to the outer surface lays a major role .. This is to ensure that the sample ready assumes the temperature of the furnace.
