from 0.85 to 1.35 watts/kg.
CRGO E & I Lamination & Stampings
We can even provide you Built up core / Stacked transformer
core assembled of miter as well as rectangular strip cores at
our place or even at customers factory as per the
requirements. This enables the manufacturer the No Wastage
and the Time Saving Advantage.

customers specifications as well as Standard Types which
are used widely in CRGO grades M4, M5 and M6.
CRGO Electrical Steel Coils
The CRGO steel is received in the form of full coil and can
be sllited in the minimum width of 10 mm and multiples
of 5 mm.The cutters are frequently grinded to control the
burr level.
Our customer can avail from us a qualitative range of CRGO
Sheet, which are fabricated from high grade of raw
materials. This range is available with us in various
dimensions, sizes and lengths.
CRNGO Rectangle Strip Lamination
CRNGO Sheets / Coils

In order to meet the various electrical requirements of the
clients, we have been engaged in offering our clients an
optimum quality EI Lamination Core in CRNGO grades
M45, M47 according to the sizes given by the customer.
CRGO Step Lap Core
The Step lap core offered by us is highly advantageous as it
+91 93 2229 0705
reduces material costs, easy assembly and low noise level.
Core design

Vertical and Horizontal Step Lap Core which is required for
High Efficiency Transformers.
CRNGO laminations are stacked to form the core assembly
as per the design provided by the customer. The core
assembly is held rigidly by steel frame clamped together to
prevent vibrations.
Torodial Core
Toroidal cores and ring cores are wound by automatic core
winding machine and are annealed in high vacuum furnace
under protection atmosphere or in continuous tunnel
furnace, which results in features like compact volume,
light, low magnetic leakage and hum & high efficiency.
Application of CRGO & CRNGO
Cold Rolled Grain Oriented Electrical Steel or C.R.G.O. is undoubtedly the most important soft magnetic material in use today. Whether in small transformer,
distribution transformer or in large transformer & generator, grain oriented electrical steel CRGO is a must for the production of energy saving electrical machines.
Grain oriented Electrical Steels are iron-silicon alloys that provide low core loss and high permeability needed for more efficient and economical electrical
transformers. CRGO Grain oriented grades of electrical steel are typically used for transformer cores and large generators.
Cold Rolled Non-Grain-Oriented Electrical steel or C.R.N.G.O. fully processed steels are iron-silicon alloys with varying silicon contents and have similar magnetic
properties in all directions in plan of the sheet. Non-oriented Electrical steel are principally used for motors, generators, alternators, ballasts, small Transformers and a
variety of other electromagnetic applications.The earliest soft magnetic material was iron, which contained many impurities. Researchers found that the addition of
silicon increased resistivity, decreased hysteresis loss, increased permeability, and virtually eliminated aging.
Technical details of CRGO
C.R.G.O.or Cold Rolled Grain Oriented Steel is available in various conventional grades generally called M3, M4, M5 & M6, in various forms such as Regular,
Semi Prime & Fully Prime BIS Approved. Recently there is lot's of demand for high permeability grades of CRGO, named as HI-B, TCH, MOH, ZDKH and Domain
refined grades of CRGO Steel. Majorly Accepted international standards such as Japanese (JIS), American (ASTM), European- German (DIN) , Russian (GOST) ,
British Standards (BS-601) and Bureau of Indian Standards (BIS) which distingush c.r.g.o. grades. Some of the CRGO & CRNGO manufacturing companies of the
world are Nippon Steel Corporation, Nlmk & Viz Stal , A K Steel , Thyseen krupp , Posco , Stahl Product , Cogent , China Steel Corporation , Steel Authority of India.
Building factor
Building factor (BF) is a very important factor used in determining the No Load Losses of a transformer. It is an empirically derived value based on previous
experiences. It ranges from 1.08 to 1.35 for three phases, three limb cores. Generally, BF is dependent on various important factors like core geometry, quality of
workmanship of core and grade of material being used.Reducing the BF is a measure that we have incorporated over time by taking precautionary step like proper
handling, maintaining appropriate parameters within the processes and controlling burr and edge camber levels.

The magnetization property is affected by impurities, grain orientation, grain size
and surface smoothness. It includes magnetostriction, saturation induction,
magneto crystalline anisotropy and Curie temperature. Higher resistivity reduces
the core loss and magnetostriction reduces by adding Silicon.
