La perte de fer de l'acier électrique non orienté est occupée par la perte d'hystersis plutôt que par la perte de courant de Foucault contraire à la perte de fer des aciers électriques orientés, et la perte de l'hystersis occupe généralement 60 à 80% de la perte totale de fer. La perte d'hystérésis est en proportion inverse de la taille du grain cristallin. C'est un moyen efficace de favoriser la croissance normale des grains des grains recristallisés au recuit final afin de diminuer la perte de fer.

Processus de production des aciers électriques
|
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 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. |
