Methods used by various Steel Industries for the waste disposal: Jindal Steel and Power Limited (JSPL) through extensive R & D activities have identified various solid wastes that could be used as productive inputs. The company pursues the policy of three R's -- Recycle, Reduce and Reuse – to manage its waste.
The three major steel manufacturing factories in Jordan dump their byproduct, steel slag, randomly in open areas, which causes many environmental hazardous problems. This study intended to explore the effectiveness of using fine steel slag aggregate (FSSA) in improving the geotechnical properties of high plastic subgrade soil. First soil and fine steel slag mechanical and engineering ...
The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route.
High-temperature waste heat from the iron and steel industry, as shown in Fig. 1, are mainly stored in products, molten slag and waste gas .Molten slag, as a kind of by-product during the steelmaking process, is exhausted in extremely high temperature and thus, it carries a great deal of high-grade heat accounting for 10% of waste energy in steel industry and 35% of high-temperature waste …
Sep 29, 2014· In case they are of alumina then the refractory waste is used for mortar manufacture. Electric steel making. Main waste material in the electric steel making is EAF (electric arc furnace) GCP dust, slag, scrap and waste refractories. Magnesia carbon waste refractories are used as slag conditioner in the EAF.

History of Steel Manufacturing in Australia . Steel manufacturing in Australia has had a chequered history. Following the discovery of deposits of iron at Iron Knob, SA, in 1840, the industry had an inauspicious start, with several unsuccessful attempts to produce pig iron and steel in South Australia, Victoria, New South Wales and Tasmania.
Steel slag, a waste product of steel yield has been used widely in road construction, because it has similar hardness to those typical coarse aggregates. Sustainability is an important aspect of developed countries, and the transportation industry is constantly trying new and innovative ways to recycle materials. Steel slag is the outcome of

As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including quarry, aggregate, and different ...
Vacuum improves both the green and cured product strength and binder effect. The lower levels of binder and moisture required permit more metal recovery from slag and other steel production residues — with individual waste streams converted into homogenous feedstock for your melt recipe.
The waste is a spent grit used for sand blasting in the cleaning operations of tankers in the dock yard. This paper presents the modified properties (chemical composition, the shape and size of the particle) of the steel grit during the blasting process and the possibility of recycling the waste as a fine aggregate in the road construction ...
We also operate a number of slag dumps, which were accumulated before ArcelorMittal owned various steel plants. These may be rich in iron and carbon-bearing materials and can be re-used in our steelmaking facilities. This lowers the need to buy materials, reducing the company's external material and supply chain footprint.

Nov 06, 2019· Slag is a high volume by-product from the metal smelting process. Globally, hundreds of millions of tonnes of molten slags are produced each year. Slag is commonly air-cooled in large pits and landfilled or used for road-based materials after crushing and screening. In some modern integrated ...
Jul 01, 2016· Steel slag and waste glass have the potential to improve the fire resistance of concrete. It should be noted that the current research is only conducted at macroscopic scales to investigate the influence of steel slag and waste glass on the mechanical properties and fire performance of concrete.
slag used for this purpose. • Pelletised or expanded slag has a vesicular texture (like volcanic rock) and is most commonly used as a lightweight aggregate. If finely ground it also has cementitious properties. In some countries, up to 80% of the cement contains granulated BF slag.5 Using slag prevents it going to landfill as waste, saves
The advances in steel slag have changed since dumping waste where ever someone saw fit. There are countless possibilities for what steel slag can be recycled into; from construction material to submerged arc welding flux. Doing this helps the environment, which is just as important as making a profit for a company, probably even more.
The history of slag use in road building dates back to the time of the Roman Empire, some 2000 years ago, when broken slag from the crude iron-making forges of that era were used in base construction. Roads made from Slag were first built in England in 1813 and, just seventeen years later, the first Slag road was laid in this country.

Nov 09, 2019· Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making alloys.Like other industrial byproducts, slag actually has many uses, and rarely goes to waste. It appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer.
If about 20 steel factories of Kotdwar generate such quantity of slag it can be calculated how much slag is being generated by about 600 induction furnace units of India. The purpose of this study is to utilize this waste as useful building material, save the steel mills from transport and disposal problems.
New Zealand Steel operates a landfill for unwanted materials that are not hazardous. (Hazardous materials are taken off-site for treatment by a specialist Auckland company.) About 140,000 tonnes of waste is deposited into the steel mill's landfill each year.
Recyclable foundry residues includes substantial proportions of slag from non-ferrous metallurgy and from stainless steel production. Slags are formed as waste or by-products of metallurgical smelting processes and are created from largely homogeneous smelts that consist of free or bonded oxides.
