Abstract:Basic oxygen furnace slag (BOFS) was ground to three levels of fineness as a replacement for cement at weight proportions of 10, 30, 50, and 70 wt.%. Fineness and weight proportion were shown to have significant effects on the flowability and setting time of the mortars.

Basic Oxygen Furnace Slag (BOFS) Graded Aggregates_CHC

BOFS graded aggregates are by-products of BOF steelmaking in a wholly integrated steel mill. Their main chemical compositions are CaO, SiO 2, Al 2 O 3, Fe 2 O 3, etc. The molten slag is cooled and solidified into basic oxygen furnace slag, which then undergoes crushing, magnetic separation, and screening to make BOFS graded aggregates.

Experimental investigation of basic oxygen furnace slag

Nov 16, 2006 BOF steel slag is a final waste material in the basic oxygen furnace steel making process. In basic furnace iron making, limestone (as fluxes) is added to react with the gangue minerals (iron ore and coke) to form iron slag. Slag is separated from the molten iron owing to the different specific gravity of molten iron and slag.

Utilization of Basic Oxygen Furnace (BOF) slag in the

May 01, 2006 Basic Oxygen Furnace (BOF) slag is a major waste product generated during the steelmaking process. In India and in most industrial countries, the use of BOF slag as a road ballast and land filler has had a very long history. This being a low end use, a study was conducted to examine the possibility of converting the slag into a hydraulic binder.

Hydration properties of basic oxygen furnace steel slag

Jul 01, 2010 Basic oxygen furnace steel slag is the most common steel slag in China. In this study, the hydration properties of this kind of steel slag were investigated. Steel slag was ground separately to 458 m 2 /kg as well as 506 m 2 /kg. Different hydration conditions were set by

Basic oxygen furnace slag Euroslag. Basic oxygen furnace slag BOS (also called LD-converter slag)is formed during the conversion of hot metal from the blast furnace into steel in a basic oxygen furnace. In this process the hot metal is treated by blowing oxygen to remove carbon and other elements that have a high affinity to oxygen.

(PDF) Modification of Basic Oxygen Furnace Slag for Cement

The use of steelmaking slag without chemical modification presents a deleterious effect on cement mechanical properties, due to the expansion caused by the presence of free CaO and MgO in the slag.

Basic Oxygen Furnace Slag Usage In Concrete Works

Basic Oxygen Furnace. Basic oxygen furnaces are equipped with air pollution control systems for containing cooling and cleaning the volumes of hot gases and submicron fumes released during the process. so a more realistic limit for charcoal usage may be around 50 of the total solid sintering fuel. Slag use as an aggregate in concrete

Concrete Produced by Steel‐Making Slag (Basic Oxygen

Oct 26, 2009 A steel‐making slag (basic oxygen furnace) obtained from the Kardemir Steelworks was modified to be used as a clinker additive in the cement industry. This study confirmed that the compressive strength values of concretes produced by addition of these steel‐making slags up to 30 mass% were within the values of Grade‐325 and Grade‐425

Recycling of Basic Oxygen Furnace Slag as a Raw Material

Abstract: The purpose of this study was to recycle basic oxygen furnace (BOF) slag in the production of autoclaved aerated concrete (AAC), and to examine the influence on the properties of AAC products. The magnetic substances in the BOF slag accounted for about 15 wt.% and the magnetic proportion increased as the particle size decreased.

Products and Services > Basic Oxygen Furnace Slag

Basic oxygen furnace slag at 1200℃ is poured into a shallow slag pot for initial cooling. The slag with reduced surface temperature is transported to a puddle, and then sweltered in a stockpile, which will make it disintegrate into aggregates naturally so that flattened graded aggregates can be collected.

Basic Oxygen Furnace Industrial Efficiency Technology

Basic Oxygen Furnace. Basic Oygen Furncace (BOF) is a pear shaped vessel where the pig iron from blast furnace, and ferrous scrap, is refined into steel by injecting a jet high-purity oxygen through the hot metal. More specifically, in a BOF: Steel Slag Usage in Cement:

High-Amount Basic Oxygen Furnace Slag MDPI

oxygen furnace slag (BOFS) and electric arc furnace slag (EAFS), which can be further divided into oxide ballast and reducing ballast, based on the smelting process [2–4]. Due to its hardness, BFS is commonly used for road construction and as concrete aggregate [5–9]; however, it must be stabilized

In-situ Temperature Effects in Basic Oxygen Furnace Slag

Basic oxygen furnace (BOF) slag is a by-product of steel plants and is different from conventional natural aggregates. Studies have shown that BOF slag asphalt concrete is able to store heat.

Chemical, Mineralogical, and Morphological Properties of

The slag generated from a steelmaking cycle is later processed, and the final product after processing is referred to as basic-oxygen-furnace slag (BOF slag). The chemical reactions occurring during the removal of impurities determine the chemical composition of the basic-oxygen-furnace slag
