Uses a simulation to show how ternary phase diagrams are interpreted. This is for a single phase, three component system. The simulation is available at: ht...These different types are referred to as furnace or tap slag, raker slag, synthetic or ladle slags, and pit or cleanout slag. Figure 1 presents a diagram of the general flow and production of different slags in a modern steel plant.

Academia.edu is a platform for academics to share research papers.Fig 1 shows a schematic diagram of chemical reactions for slag ing in EAF. The diagram shows the reaction sites during injection of carbon during steel melting-refining processes in an EAF. It can be seen from the diagram that CO formation is a very complex function of several process variables consisting of size, type and mass flow rate of ...

PURPOSE: A reduction method of sulfur contained in molten slag after continuous casting process by oxygen injection is provided to recycle as desulfurization agent in LF, thus reduce the quantity of lime used in desulfurization process. CONSTITUTION: To remove sulfur contained in molten slag of ladle after continuous casting process, a lance is inserted into a ladle, and oxygen is ejected ...The molten slag is collected and quenched with water-forming boiler slag. When the molten slag comes in contact with the quenching water, it fractures, crystallizes, and forms pellet-shaped particles. Boiler slag is a vitreous, grained material made up of hard, black, and angular particles with a smooth and glassy appearance (ECOBA, 2015).

Complex bands of crystallized/glassy phases are often present in different combinations due to both the slag properties and locally varying in-mold conditions, such as powder melting rate, molten slag infiltration and element pick-up.8,10,11 The slag film is rather thin, with thicknesses between 0.25~4 mm,11 or even finer (0.05∼0.5 mm).12Phase diagrams of slag systems have played an important role in the history of iron and steel making. The art of phase diagram measurements for slag systems is gradually disappearing from common practice. The chapter serves as an important archive of the methods developed by the pioneers in this technology. 1.

From the diagram, the secondary phase should be CaSi 2 when X Ca /X Fe ... Slag is readily skimmed from the surface of the molten metal or the metal can be drained from beneath the slag, but slag can adhere strongly to the cooled metal and be very difficult to remove. It may be possible to control the composition of the slag phase to influence ...Synthetic Slag for Secondary Steelmaking. satyendra; March 28, 2017; 1 Comment ; Al2O3, baicity, CaO, desulphurization, fluidity, inclusions, melting point, phase diagram, sdcondary steelmaking, synthetic slag,; Synthetic Slag for Secondary Steelmaking. Synthetic slag consists of prepared mixture of several individual oxides which is used during secondary steelmaking to assist …

Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.Phase Diagrams • Indicate phases as function of T, Co, and P. • For this course:-binary systems: just 2 components.-independent variables: T and Co (P = 1 atm is almost always used). • Phase Diagram for Cu-Ni system Adapted from Fig. 9.3(a), Callister 7e. (Fig. 9.3(a) is adapted from Phase Diagrams of Binary Nickel Alloys, P. Nash

In order to take data information from the slag property diagram in a ternary system automatically and actually, a picture recognition and drawing software has been developed by Visual Basic 6.0 based on the image coding principle of computer system and the graphics programming method of VB. This software can transform the ternary system isopleth diagram from bitmap format to data file and ...Nickel Slag Air-cooled nickel slag is brownish-black in color. It crushes to angular particles but has a smooth, glassy texture. The specific gravity of air-cooled nickel slag may be as high as 3.5 (15), while the absorption is quite low (0.37 percent). (3) The unit weight of nickel slag is somewhat higher than that of conventional aggregate. ...

The slag chemistry in primary lead smelting slags, as described by the system ZnO-FeO-Fe2O3-PbO-CaO-SiO2, is systematically examined and presented so as to reflect the various process conditions ...Fabrication of Welding Slag Cleaning Machine. Welding is the process of joining of two materials by using filler rod, while joining the materials the high amount of heat is generated in welding surface, so oxidation can take place over the job, in order to prevent the oxidation the flux material is coated over the welded area. This flux coating ...

Based on the main chemical components of steel slag includes CaO, FeO, Al 2 O 3, SiO 2, and MgO. When the content of CaO exceeds 50%, it can replace part of lime as a flux for sinter.

It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. The molten slag, which absorbs much of the sulfur from the charge, comprises about 20 percent by mass of iron production. Figure 3-1 presents a general schematic, which depicts the blast ...

Slag is normally seen as elongated lines either continuous or discontinuous along the length of the weld. This is readily identified in a radiograph, Fig 1. Slag inclusions are usually associated with the flux processes, ie MMA, FCA and submerged arc, but they can also occur in MIG welding.chrome slag in the phase diagram is shown in Figure 3. The proportion of quartzite in the charge mix controls the right slag composition. The slag composition is tested every day by sampling and analysis. The typical ferrochrome slag composition is 30 % SiO 2, …
