approximately 21 million tons of steel industry slag are produced each year in the united states, and many productive commercial uses of slag have been developed (e.g., road bed, fill material). however, because slag contains heavy metals at concentrations that are higher than in most soil, questions have been raised regarding the need to evaluate the potential human health and environmental.paper open access physical and chemical properties of,steel slag contains silicon, calcium, phosphorus and other elements, which are necessary for the growth of crops. as steel slag is calcined at high temperature during smelting, its solubility increases and it is easily absorbed and utilized by plants. at present, phosphate fertilizer, silicon fertilizer and.estimating the physical properties of slags,slags, and their physical properties are very dependent on the silicate structure developed in the molten slag3. the dependence of property on structure is in the hierarchy, viscosity (η) > electrical conductivity (κ) and thermal conductivity (k) > thermal expansion coefficient (α) > density (ρ) > surface tension (γ) > c p and enthalpy. in fact, some workers.chemical & physical properties of steel,chemical & physical properties of steel basic physical properties of steel. steel has a density of 7,850 kg/m 3, making it 7.85 times as dense as water. its melting point of 1,510 c is higher than that of most metals. in comparison, the melting point of bronze is 1,040 c, that of copper is 1,083 c, that of cast iron is 1,300 c, and that of
the primary components of iron and steel slag are limestone (cao) and silica (sio 2). other components of blast furnace slag include alumina (alsub>2 o 3) and magnesium oxide (mgo), as well as a small amount of sulfur (s), while steelmaking slag contains iron oxide (feo) and magnesium oxide (mgo). in the case of steelmaking slag, the slag contains metal elements (such as iron) in oxide form, however.chemical composition of steel,chemical composition of steel. steel is an alloy of iron and other elements. some elements are intentionally added to iron for the purpose of attaining certain specific properties and characteristics. other elements are present incidentally and cannot be easily removed. such elements are referred to as “trace” or “residual” elements..what are properties of wrought iron,many products described as wrought iron, such as guard rails, garden furniture and gates, are actually made of mild steel. wrought iron is an iron alloy with very low carbon content (less than 0.08%) with respect to cast iron (2.1% to 4%). the microstructure of wrought iron shows dark slag inclusions in ferrite.it is soft, ductile, fibrous variety that is produced from a semifused mass of.a. physical coke properties,a. physical coke properties a high quality coke is characterized by a definite set of physical and chemical properties that vary within a narrow limit thereby ensuring consistency in the quality. coke is the only solid material remaining below the cohesive zone in the blast furnace (refer figure – a for various zones of operation in blast
3. steel (made from bessemer converter) wrought iron and its properties: wrought iron is a mechanical mixture of pure iron and silicate slag; its carbon percentage is 0.02% to 0.03%; wrought iron is never cast or difficult to cast; wrought iron is having high ductile, corrosion-resistant, fatigue resistant.wrought iron: properties and uses,wrought iron does not contain impurities and is thus intensely soft. due to very low carbon content its melting point is high and it cannot be used as casting alloy. due to poor strength it has very little use. it cannot be heat treated for changing its physical properties. due to the presence of slag in wrought iron, it resists corrosion..effect of portland cement replacement by bssf steel slag,the experimental work consisted of physical-chemical characterization tests of bssf steel slag, as well as characterization of the properties in the fresh and hardened concrete state produced by the replacement of cement by bssf steel slag fines at 3%, 6% and 12%. the properties analyzed were: specific mass, incorporated air content.21 chemical elements and effects on steel mechanical,we list 21 chemical elements and effects on mechanical properties of steel. some common steel chemical elements like c, p, s, si, mn, cr, ni, co, mo etc
