Calculations were performed considering homogeneous medium with

A Novel Hysteresis Model Of Magnetic Field Strength

Hysteresis characteristics of grain-oriented electrical steel were studied through the hysteresis loop. Existing hysteresis fitting simulation methods were summarized, and new Fe-3 Si grain-oriented electrical steel hysteresis loop model was proposed. Undetermined coefficients of the magnetic field intensity and magnetic flux density were determined by both the fixed angle method and the ...

Feasibility Study Of Dephosphorization Of Slag Generated

Jun 02, 2017 Basic oxygen furnace slag BOF slag is an unavoidable by-product of steelmaking process of basic oxygen furnace. The main chemical constituents of BOF slag are CaO, FeO, Al 2 O 3 , SiO 2 and MgO. Due to its high metallic value FeO 16-20 and lime content CaO 45-50, it is possible to use in iron making and steelmaking process to replace lime and recover iron and CaO.

Metal Profile Iron Properties And Characteristics

Jan 12, 2020 One of irons identifying characteristics is that it is strongly magnetic. Exposed to a strong magnetic field, any piece of iron can be magnetized. Scientists believe that the Earths core is made up of about 90 iron. The magnetic force produced by this iron is what creates the magnetic

Does Steel Block Or Improve Magnetic Strength

If the height of the steel cylinder is 18 or less, the field strength is weaker. The steel reduces the field strength at our measurement point. Wed be better off just leaving an air gap. If the height is or greater, we expect a stronger field strength. The steel stretches or extends the strong field farther away from the magnet.

Steel Electricarc Steelmaking Britannica

Steel - Steel - Electric-arc steelmaking About one-quarter of the worlds steel is produced by the electric-arc method, which uses high-current electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. External arc heating permits better thermal control than does the basic oxygen process, in which heating is accomplished by the ...

Utilization Of Waste Copper Slag To Produce Directly

The DRI was obtained after magnetic separation. The grinding fineness of reduced pellets was about 95 passing 0.074 mm and the magnetic field intensity was 0.08 T. The chemical compositions of copper slag and iron concentrate were measured using chemical analysis.

Separation Of Febearing And Pbearing Phase From The

2. Experimental. The chemical composition of steelmaking slag from Laiwu Iron and Steel Corporation is listed in Table 1.The super gravity field, as shown in Fig. 1, was generated by the centrifugal apparatus.The resistance wire heating furnace balanced with a counterweight across the rotation axis was placed into a centrifugal rotor.

Magnets Vs Steel Kampj Magnetics

We dont sell steel strike plates, but lets say you used an NSW82 0.45 steel washer. The two-magnet solution is more expensive, at 2 x 0.99 1.98. The magnet-to-steel method at 0.99 0.45 1.44. The magnet-to-steel is the winner if cost is the only factor.

Sustainable Utilization Of Steel Slag From Traditional

Shan et al. used the principle that steel slag and blast furnace slag can activate each other to promote hydration and added a 25 steel slag and 25 blast furnace powder as an admixture to increase the strength of the cement, with results showing that the 28 day bending strength and compressive strength of cement was 21.2 MPa and 55.0 MPa, respectively, which recently met the strength requirement of 52.5 grade Portland slag
