Acid-washing and annealing requirements for I Shape Transformer Core Silicon Steel

- Mar 21, 2019-

The shape of the transformer core silicon steel has low iron loss during operation. This is the most important indicator of the quality of the product. All countries will divide the grade according to the iron loss value. The lower the iron loss, the higher the grade. The magnetic induction (magnetic inductance) is high under a strong magnetic field, which reduces the volume and weight of the core of the motor and the transformer, and saves silicon steel sheets, copper wires and insulating materials.

The surface of the moldable transformer core silicon steel is very smooth, flat and uniform in thickness, which can increase the filling factor of the core. The punching of the whole product is good, and it is more important for the manufacture of miniature and small motors. The surface insulating film has good adhesion and weldability, and can be used for corrosion prevention and improvement of chipping property.

Shapeable transformer core silicon steel pickling requirements

The moldable transformer core silicon steel can be operated to remove oxides from the hot rolled steel strip through a descaler and a hydrochloric acid tank to prevent defects on the surface of the cold rolled product. In order to ensure the thickness and material of different applications, the deceleration ratio is set at 40%-90%, and advanced control equipment such as automatic thickness control and automatic shape control is realized.

Annealing of a moldable transformer core silicon steel

The moldable transformer core silicon steel is a project to soften the hardened steel strip material in the cold stamping project. Through metal heating and rapid cooling, deep-processing steel and high-tensile steel are produced, and boxing (hood retreat) annealing and continuous annealing are adopted.
