of lightweight concrete, using blastfurnace slag in place of stone as aggregate for floor construction this reduced the density of the concrete by 25 percent, with a corresponding reduction in the loads the building columns needed to carry. The second was the increase in
Blast furnace slag contains little metal, and recovery of metal (even iron) from it is usually not important. About 220–370 kg of slag is produced per ton of iron. Blast furnace slag was used as early as 1880 as a phosphatic fertilizer. Today, blast furnace and steel slag have found a wide appliion in areas such as cement production, road

Basic Slag is a recycled product produced from the iron making process. When manufacturing iron and conversion of steel in an open hearth furnace the principle products used are iron ore, coke, dolomitic limestone, fluxing stone, and various additives.
Blast furnace economics are such that larger units have lower unit production costs, hence there has been a trend to bigger and bigger furnaces. Modern blast furnaces produce more than 10,000 tonnes per day. For general information about merchant pig iron, please visit the pig iron page. Modern blast furnaces produce more than 10,000 tonnes per
Aug 09, 2014 · Dry Granulation of Blast Furnace Slag for Energy Recovery Around 300 kg of liquid slag is produced as byproduct while producing one ton of hot metal in a blast furnace (BF).This slag is at a temperature of around 1500 deg C and has a sensible heat of approximately 400 M Cal per ton.
Blast Furnace Slag Granulation SaintGobain ceramic materials extend the lifetime of slag granulation equipment over traditional refractory lined and hardened steel components. Abrasion and corrosion can hinder operational efficiency and increase downtime.
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.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with
