In Brazil, byproducts from the steel industry consist of 42 % blast furnace slag, 27 % steelworks slag and 31 % other byproducts such as dusts, sludges, etc., according to figures from the Brazil Steel Institute for 2017. 92 % of the approximately Mta of blast furnace slag was recycled in 2017, of which 99 % went to cement production.
Converter slag In the same way as aircooled blast furnace slag, converter slag is cooled slowly by natural cooling and water spray in a cooling yard. It is then processed and used for various iron and steel slag (converter) appliions. Approximately 110 kg of slag is generated for each ton of converter steel. Electric arc furnace slag . Get price
Shaping the future – converter steelworks from SMS group. Since the early 1950s, SMS group and its predecessor companies have been using their knowhow for highly productive and modern converter steelplants for carbon and stainless steel worldwide. SMS group is one of the leading companies in this market and meets the growing demands of its ...
Steelmaking slag is generated by the process that turns pig iron produced by a blast furnace into tough and highly workable steel. Converter slag is the oxidized material that is generated when lime and other auxiliary materials are added and oxygen is blown onto the pig iron in order to remove carbon, phosphorous, sulfur, and other components from the pig iron and refine it to produce strong ...
· The basic oxygen converter steel slag (hereafter called steel slag in this paper) is rich in silie minerals, such as dicalcium silie (C 2 S) and tricalcium silie (C 3 S), similar to the mineral components of cement clinker, and it possesses a certain hydration activity and cementitious materials after grinding [22–24].
The main solid coproducts produced during iron and crude steel production are slags (90% by mass), dust and sludge. On average, the production of one tonne of steel results in around 200 kg of coproducts for the electric arc furnace (EAF) route and 400 kg for the blast furnace .
converter slag of steel in clinker production converter slag of steel in clinker production. Producing Portland cement from iron and steel slags and limestone. Abstract. The slags from blast furnace (iron making ) and converter (steel making) after magnetic separation are mixed with limestone of six differ ent compositions.
Steelmaking slag consists of converter slag that is generated by converter and electric arc furnace slag that is generated during the electric arc furnace steelmaking process that uses steelscrap as the raw material. Characteristics of iron/steel slag The typical compositions of iron/steel slag .
· Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary kiln.
Most slags from steel pl ant derive from this pr ocess, with an average of kg of slag generated per tonne of st eel carbon cost of Slag production in the blast furnace16/4/2015 4th Slag valorization symposium Leuven 7 Low CO2 values for GBFS should lead to an obligation to use GBFS over clinker for the cement user but also to a decrease of production for the steel maker since the ...
Converter slag of steel Almost the same amount of converter slag production of about 600000 tons per year and more than 10 million tons in stock exists in the mill and is increased daily. Being high in iron oxide Fe 2 O 3 Fe 3 O 4 and metallic Fe particles this slag has not been used in the cement industry although Table 1.

of blast furnace slag such aircooled slag and granulated slag are being generated from the steel plants. In India around 40% of this slag is produced in the form of granulated slag. The specific gravity of the slag is approximately with its bulk density varying in the range of 1200–1300kg/m3. The color of granulated slag is whitish.
Nov 29, 2016 · Steel slag is produced by the conversion of raw iron into steel around 125 million tons of it per year. Much of that is dumped and only a small portion used, in embankments. That's a shame, professor Jos Brouwers says, because the mineralogical composition very closely resembles that of
converter slag of steel in clinker production. Steelslag: a supplementary cementious material and basis . Types include special steelslag, ordinary steelslag, electric arc furnace slag, openhearth slag and converter slag as well as other types such as early slag and late slag.
Converter steel slag is produced in large quantities as byproduct of primary steelmaking, which is mainly landfilled or used as an aggregate The high reactivity of converter steel slag with CO2 makes it an ideal material for CO2 capture by forming calcite even at ambient temperature and pressure.
· During converter tapping, in addition to the crude steel tapped into the ladle, some converter slag is also carried over into the steelmaking ladle, hence the name 'carryover slag'. Since slag contains impurities from primary refining, it would be very desirable to have zero slag carryover, as these impurities can revert to the steel in the ladle.
Converter slag of steel Almost the same amount of converter slag (production of about 600,000 tons per year and more than 10 million tons in stock ) exists in the mill and is increased daily. Being high in iron oxide (Fe 2 O 3, Fe 3 O 4) and metallic Fe particles, this slag has not been used in the cement industry, although Table 1
