This research has strong implications for control of slag metal reactions in ultra-high-powered direct current electric-arc furnaces which operate with a strong applied electric field across the slag layer Also studied were the effects of pressure on the kinetics of iron

The most common steel making technology is the Bf-Bof Route Coke is used in Blast Furnace (BF) both as a reductant and as a source of thermal energy It involves reduction of ore to liquid metal in the blast furnace and and refining in convertor to form steel The various stages of the steel

steel research international Volume 84 Issue 2 Full Paper Investigating the Effect of Slag on Decarburization in an AOD Converter Using a Fundamental Model Nils I Andersson Div Applied Process Metallurgy KTH Royal Institute of Technology Stockholm 100 44 Sweden

Improving energy efficiency has already been a focus of manufacturers' Research Development efforts for decades and notable progress has been made For instance the energy intensity (amountof energy required to produce one tonne of steel) in the US steel industry is now only 30% of

IOP Conference Series: Materials Science and Engineering

A commercial experiment system of unpolluted deoxidization with applied electric field is designed and fabricated based on laboratory and pilot research A simulation model for the electrochemical deoxidization system between molten steel and slag with direct current electric field

Today iron and steel slag is used in many fields where its unique characteristics can be put to effective use As a result of growing environmental awareness iron and steel slag is highly regarded as a recycled material that can reduce impacts on the environment due to its resource-conservation and energy-saving effects

Jul 10 2017The transformation of CO2 into a precipitated mineral carbonate through an ex situ mineral carbonation route is considered a promising option for carbon capture and storage (CCS) since (i) the captured CO2 can be stored permanently and (ii) industrial wastes (i e coal fly ash steel and stainless-steel slags and cement and lime kiln dusts) can be recycled and converted into value-added

As a result any product made using Carbicrete technology permanently sequesters CO2 while turning industrial waste (steel slag) into a high-quality construction product Concrete made using this process meets the same specifications as cement-based concrete has lower material costs and possesses better mechanical and durability properties

Steelmaking is the process of producing steel from iron ore and/or scrap In steelmaking impurities such as nitrogen silicon phosphorus sulfur and excess carbon (most important impurity) are removed from the sourced iron and alloying elements such as manganese nickel chromium carbon and vanadium are added to produce different grades of steel

The research progress of steel slag utilization in agriculture is reviewed in the present paper The review covers different aspects by summarizing its use as fertiliser as well as agent its potential use for soils amendment and by paying attention to different technologies and methodologies aiming to improve the quality of the slag in

Jan 01 2012The research progress of steel slag utilization is overviewed in the present paper 2 Physical and chemical characteristics of steel slag The density of steel slag lies between 3 3-3 6g/cm 3 In this process decarbonization slag and LDS are recycled and applied to dephosphorization (Fig 2) In China Northeastern University [16] and Xian

A number of carbon-rich (containing up to 47 wt% C) and lime-rich (containing up to 96 wt% of CaO-compounds) waste products from the pulp and paper industries can be used in iron and steel industry as fuels and slag formers for various metallurgical processes such as blast furnaces (BF) cupola furnaces (CF) argon oxygen decarburization (AOD) converters and electric arc furnaces (EAF) In

Applications of Steel Slag Powder and Steel Slag Aggregate

The steel slag used was the converter steel slag with 1 5% f-CaO (by mass) Figure 1 shows the particle size distributions of the cement and steel slag powder The X-ray diffraction (XRD) patterns of the steel slag are shown in Figure 2 The major chemical components of the cement and steel slag are shown in Table 1

The steel slag (AMSteelC) and slag from two legacy sites (ILSS2 ILSS5) contained slightly less C with concentrations that ranged from 1 5 to 2 7 wt % C Carbonate C was highest in ILSS2 at 2 3 wt % C and accounted for the majority of the C in the sample

The hot stage steel slag (BOF) pyrolytic self-slaking process has made progress and are applied in a number of large steel companies in China The slag valorisation in China improved gradually not only in quantity but also in quality thereby increasing the economical and environmental benefits

The analysis of highly reduced slags has shown that it is possible to remove virtually all of the cobalt and nickel from the olivine in the slag Nickel-copper converter slag 'B' - 3 2 MVA Large-scale testwork on converter slag was conducted during 1994 on a 3 2 MVA DC-arc furnace operating at a
