A slag is a mixture of oxides, mainly of silicon, aluminum, calcium, magnesium, iron, among traces of others. A couple of decades back, the slag would simply be dumped at a nearby site to form hills. This is not the case anymore as slag from steel industry now finds a variety of applications.
has similar appearance and properties to igneous rock. The steel slag is crushed to size and is normally produced through a range of sizes up to about 75mm. Both BOS and EAF steel slag have similar physical and chemical properties, typical properties are detailed in Austroads Guide Part 4E - Recycled Materials.
Mar 04, 2017018332Perhaps the earliest appearance of Slag in American history came with the Pilgrims.
The steel slag contains higher amount of iron and its physical characteristics are similar to air-cooled iron slag. The LD slag is cooled, crushed and screened. The fines are utilised in sinter making and lumps are charged in the blast furnace. The iron content is the major basic difference between BF slag and steel slag.
It has been found that the density of LD slag lies between 3.3-3.6gcm. 3 Due to its high Fe content, steel slag looks in appearance a loose collection, and appears hard and wear resistant. The grindability index of steel slag is 0.7, in contrast with the value of 0.96 and 1.0 for blast furnae slag and standard sand respectively Hou et al., 2010.

Low-alloy slag residue from rock drill steel is also being tested as a slag asphalt component on the Sandviken site. Slag asphalt is a widely accepted product as it has higher torsional strength than regular asphalt and properties, which are well suited in places with high torsional loads, making it ideal for the raw material yard.
SFS-Rail steel furnace slag-rail, is fundamental for the economic and environmental sustainability of the railway infrastructure.
Steel in concrete is usually in a noncorroding, passive condition. However, steel-reinforced concrete is often used in severe environments where sea water or deicing salts are present. When chloride moves into the concrete, it disrupts the passive layer protecting the steel, causing it to rust and pit.

JFE Steel carried out an on-site construction exami-nation using five kinds of steel slag in order to find out whether steel slag can be used as a material in Sand Compaction Pile method with static load compaction. It showed equivalent performance in the result diameter of a pile and construction time compared with the conven-tional natural sand.
The slag pot is the necessary equipment used in metallurgical steelmaking plants It needs to be produced through dozens of processes, and each process will have an impact on the quality of the slag pot The cast steel slag pots and ladles produced by CHAENG have been recognized and.

KOBM Slag Brief Description. Kl246ckner Oxygen Blowing Maximillanshuette Slag KOBM Slag is a co-product of the steel making process used in New Zealand. Physical Description. KOBM slag is typically light to medium brown in colour.
A promising type of steel slag for applications is the ladle furnace LF slag, which is also known as the basic slag, the reducing slag, the white slag, and the secondary refining slag. The LF slag is a byproduct from further refining molten steel after coming out of a basic oxygen furnace BOF or an electric arc furnace EAF.
