Product Description

The iron loss of non-Oriented Electrical Steel is occupied by the hystersis loss rather than by the eddy-current loss contrary to the iron loss of oriented electrical steels, and the hystersis loss occupies generally 60-80% of the total iron loss. The hysteresis loss is in inverse proportion to the crystal grain size. It is an effective means to promote the normal grain growth of recrystallized grains at the final annealing in order to decrease the iron loss.

Production process of electrical steels

smelt	Silicon steels is mainly smelted by oxygen converter, combined with vacuum treatment of molten steel and AOD technology during smelting and aluminum (0.2-0.5%) content to meet the requirements of different magnetic properties. The silicon and aluminum content of high-grade silicon steel sheets should be increased accordingly. Carbon, sulfur and inclusions should be minimized.
rolling	The magnetism, surface quality, filling factor and punchability of cold-rolled Grain Oriented Silicon Steel sheets are better than those of hot-rolled silicon steel sheets, and they can be produced in coils. Therefore, some countries have stopped producing hot-rolled silicon steel sheets since the 1960s. China adopts a low temperature of about 900 ℃ one-time rapid hot rolling and stacking annealing under the protection of hydrogen to manufacture hot-rolled silicon steel sheets. The yield is high, and the surface quality and magnetic properties of the finished products are good.
pickling	The oxides of the hot-rolled steel strip are removed by the descaling machine and the hydrochloric acid tank to prevent surface defects of the cold-rolled finished product.
cold rolling	In order to ensure the thickness and material for different purposes, the deceleration ratio is set at 40%-90%, and advanced control equipment such as automatic thickness control and automatic shape control is realized.
annealing	It is a process of softening the material of the steel strip hardened in the cold stamping process. Through metal heating and rapid cooling, steel for deep processing and high-tensile steel are produced, and boxing (cover annealing) annealing and continuous annealing methods are adopted.
insulating coating	When the silicon steel plate is processed into an iron core, in order to improve its processing performance and prevent eddy current loss equivalent to the multiplication of the thickness of the steel plate, continuous coating equipment is used to spray insulating coating liquid on the upper and lower sides of the steel plate.
