Soft ferrite materials are widely used in the construction of high frequency transformer for power electronic applications. Core loss calculation is essential both in the selection of soft ferrites and the design of high frequency transformer. Traditionally, the Steinmetz equation is used to evaluate the core loss of magnetic materials under sinusoidal excitation. …
Klin alignment is critical. ... Because OEMs and repair companies apply different methods to calculate kiln misalignment, you might find it challenging to evaluate the service proposals you receive from suppliers performing their version of a hot-kiln alignment. When looking for support in kiln alignment, there are a few considerations to
VOL. 5 NO. 1 OCTOBER, 2010 STEEL TECH 11 from an industrial coal-based sponge iron rotary kiln process. We have developed a fairly comprehensive mathematical model for the direct reduction of iron ore
Such higher loss of gangue material produces iron rich product. The iron oxide loss in the fly ash is about 42% which may be due to higher velocity of the waste gas. The calculations show that as per plant practice, air requirement is about 2497.4 m 3 per ton of ore feed. This should be very controlled very carefully which will sustain reducing ...
Engineering design calculations often involve a blend of various calculation methods depending on the aspects of the design team need to evaluate. These may include load analysis, heat transfer analysis, fluid dynamics analysis, and material stress calculations.
