Application Engineering

Standard Production Flow Chart

Electrical Steel comprise of large family of steels, generally called soft magnetic materials. Without electrical steel the economic generation, distribution & utilization of electricity would not be practical. Wide diversity of electrical machines, equipment and systems requires specifi c electro-magnetic and mechanical behaviour of core material. Our PowerCore products come to you with a host of advantages like several choices of insulation coatings & nominal thicknesses, slit widths and cut sheets in rectangular or parallelogram shapes. The designer can select optimal grade required from standard high permeablity and superior core losses for applications star-ting from micro motors to power generators and transformers. Our highly skilled Application Engineering team works very closely with our customers to develop and supply customised PowerCore products.

For grades other than mentioned above please enquire separately. The specimens are tested as sheared. Values are measured according to test method in IS648 & IS649.

Non Grain Oriented Electrical Steel PowerCore Fully Processed - NGO FP

With the fully processed PowerCore standard grades, all impor-tant quality features are fully developed. In many cases, magnetic properties are better than those specified in the standards.All properties are extremely uniform thanks to reliable process control and the use of state-of-the-art equipment. The use of

hot strip mainly from the casting-rolling line means that low core losses can be achieved even with reduced silicon and aluminum contents. As saturation polarization increases with reduced alloy contents, our grades display higher polarization values despite lower core losses in the upper magnetization level.
