Three Phase EI 100 EI 200 EI 250 EI 300 EI 500 Silicon Steel EI Lamination

Silicon steel sheet performance indicators:

A. The iron loss is low. The most important indicator of quality, all countries in the world divide the grades by iron loss value. The lower the iron loss, the higher the grade and the higher the quality.

B. High magnetic induction intensity. Under the same magnetic field, silicon steel sheet with high magnetic induction can be obtained. The volume and weight of the motor or transformer core made of it are relatively small, and relatively speaking, silicon steel sheet, copper wire and insulating material can be saved.

C. High stacking coefficient. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, and the stacking coefficient of the manufactured iron core is improved. D. The punching performance is good. This is more important for the manufacture of small and micro motor cores.

E. The surface has good adhesion to the insulating film and good solderability.

F, magnetic aging

G. The silicon steel sheet must be delivered after annealing and pickling.

siliconsteelsheets is a ferrosilicon soft magnetic alloy with extremely low carbon content, generally containing 0.5 to 4.5% silicon. Adding silicon can improve the resistivity and maximum magnetic permeability of iron, and reduce the coercive force, core loss (iron loss) and magnetic aging. Mainly used to make iron cores of various transformers, motors and generators. The world's silicon steel sheet production accounts for about 1% of the total steel (see precision alloys).

Jiangyin hengtong was found in 1989.it is a large scale , standardization, consideration, and information all constitute important factors in the development of steel managing enterprises. The company located in jiangyin city-the NO.1 of the TOP 100 cities in China ,faces the shanghai on the east and near the changjiang river on the north ,with the ascendant geographical location and convenient transportation makes goods reach to destination very quickly.

Now we have two companies, jiangyin hengtong ,jiangsu smart motor technology（jiangsu shuaijin） ,about 200 employees ,30% of them is professional and technical talents.jiangyin hengtong is as a window of the group . it got the ISO9001 ROHS SGS ISO14001 IATF16949 and the horner of jiangyin high-tech enterprise,jiangyin key enterprise . it covers about 1300 are and has two set of slitting machine , twelve sets of annealing equipment .more than 50 sets of punching machine and cutting machine. We can produce most of kinds EI type ,UI type and other silicon steel sheet in the market ,Contain the thickness 0.23mm 0.30mm 0.35mm 0.5mm etc .annual quantity is about 50000 ton.

In the past 20 years, jiangyin hengtong made a great achievement in the filed of transformer industry , Power tools industry, household appliances industry, welding industry, automobile manufacturing industry .well-known and trust by the domestic and foreign enterprises ,such as microtek ,luminous , leader,EAGTOP,GREE etc. The products has been sold to US, Brazil ,India ,EGYPT,RUSSIA AND POLAND. Jiangyin hengtong has been the most important punching company in the word .
