The higher the percentage of granulated slag was, the higher the density, the elastic modulus in compression and the compressive strength of the concrete were. Dry shrinkage of the concrete increased by adding a greater amount of EAF granulated slag. Keywords Industrial by-products, electric arc furnace granulated slag, eco-sustainability, concrete
Electric arc furnace slag is a byproduct of the production of steel in an electric arc furnace. In electric arc furnaces the charge materials (scrap iron and steel) are loaded into the furnace and directly exposed to electric terminals. The current passing through the terminals creates an electric arc that melts the charge materials.

Iron and steel slag is also known as ferrous slag, which is produced by using limestone and silica sand, iron ore, coal, and limestone. The iron and steel slag is extracted by numerous processes like blast furnace slags, granulated blast furnace slags, sir cooled blast furnace slag, steelmaking slag, converter slag and electric arc furnace slag.
Jun 17, 2020· Slag ing has become an important and critical practice for the modern electric arc furnace (EAF) since a good ing slag contributes considerable efficiency and other benefits to the process. The quality of the slag ing is an important factor in the EAF steelmaking process since it ensures that the heat from the liquid bath is not ...
The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron.
Apr 27, 2019· 2.1. Electric Arc Furnace Slag (EAF Slag) As shown in Figure 1, slags are generally classified into two categories: Blast furnace (BF) slag and steel-making (SM) slag.Electric arc furnace (EAF) slag, one of the SM slags, is produced by refining the process of recycled steel scrap in the electric arc furnace.

Types of Slag. Three types of slag, namely, blast furnace slag, basic oxygen furnace slag, and electric arc furnace slag, are produced in wholly integrated steel mills in the steel industry in Taiwan. The so-called steel slag or steelmaking slag refers to basic oxygen furnace slag and electric arc furnace slag.
IIMA Fact Sheet #10 (2018) [email protected] Use of Granulated Pig Iron (GPI) in the Electric Arc Furnace (EAF) • Steel production in the EAF continues to grow worldwide. • EAF operators prefer to use GPI to blend with scrap and other metallics due to its high Fe and energy (, Si) content, low gangue and chemical purity, rapid melting proper-
