Blast Furnace Slag, Post-Industrial Waste or Valuable

The recycling of aggregates from post-industrial waste such as Blast Furnace Slag, due to its non-homogeneous nature depending on the products generated in the furnace, presents a challenge. In Steel slag is one of the most common waste products from the steelmaking industry. Conventional methods of slag disposal can cause negative impacts on humans and the environment. In this paper, the process of steel and steel slag production, physical and chemical properties, and potential options of slag recycling were reviewed. Since steel Assessment of Electric Arc Furnace (EAF) Steel Slag Waste’s Recycling

Russian researchers develop wasteless joint processing of

Scientists of Ural Federal University and the Institute of Metallurgy of the Ural Branch of RAS (Russian Academy of Sciences) have developed and successfully tested the technology of joint non-waste processing of electric furnace and ladle slag to obtain pig iron and Portland cement clinker.. A paper on their work is published in the Abstract: The granulation of blast furnace (BF) slag with water quenching has many disadvantages, such as high water consumption and difficulty in heat recycling. The dry granulation technology to treat the BF slag is very important. The application of BF slag depends on the content of amorphous solids in the slag after treatment.

A Review on Stabilization of Ladle Furnace Slag-Powdering Issue

Ladle furnace (LF) slag plays an important role in modern steel making in terms of quality and productivity. The major challenge of using LF slag is its dusting problem. The polymorphic transformation of β-dicalcium silicate (monoclinic) to γ-dicalcium silicate (Orthorhombic) at about 450 °C is the leading cause of its disintegration. Recycling slag minimizes waste and disposal costs, reduces energy use, extends furnace life, and lowers the amount of additives needed to make slag. The concerns with slag recycling are Slag: From By-product to Valuable Construction

Slag recycling recovery

The import quantities for slag (mostly granulated blast furnace slag) in the USA were 2.3 Mta in 2019 after 2.0 Mta in 2016. In 2016, 8.2 Mta of blast furnace slag was produced, of which only 2.9 Mta (35.4 %) was granulated slag and 5.3 Mta (64.6 %) was air-cooled blast furnace slag. In addition, 7.4 Mta of steelworks slag was produced.Reduce, reuse, and recycle are important techniques for waste management. These become significant for improving environmental and economic condition of industries. Integrated steel industries are generating huge amounts of steel slag as waste through the blast furnace and Linz–Donawitz (LD) process.
