Silicon steel sheet (silicon steel sheet) is mainly smelted with oxygen converter (also can be smelted by electric arc furnace), with molten steel vacuum treatment and AOD technology (see refining outside the furnace, using die casting or continuous casting method. According to different uses, change silicon during smelting (0.5 ～ 4.5%) and aluminum (0.2 ～ 0.5%) content to meet different magnetic requirements. The silicon and aluminum content of high-grade silicon steel sheet is correspondingly increased. Carbon, sulfur and inclusions are minimized.
Cold-rolled silicon steel sheets have better magnetic properties, surface quality, fill factor and punching properties than hot-rolled silicon steel sheets and can be produced in coils, so some countries have stopped producing hot-rolled silicon steel sheets since the 1960s. China uses hot-rolling at a low temperature of about 900 ° C for one time and hot-rolled annealing under the protection of hydrogen to produce hot-rolled silicon steel sheets, which has a high yield rate and good surface quality and magnetic properties.

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.
