The manufacturing process of a cold rolled silicon steel laminated transformer core is a meticulous endeavor, involving several key steps to ensure the desired properties and performance of the final product.
The initial step in this manufacturing process entails the careful selection of raw materials. With great discernment, high-quality silicon steel is chosen for its exceptional magnetic properties and minimal core losses. The composition and grain orientation of the steel play a crucial role in determining the efficiency and performance of the transformer core.
Having completed the raw material selection, the silicon steel proceeds to undergo a cold rolling process. This particular process involves passing the steel through a series of rollers, effectively diminishing its thickness and enhancing its magnetic properties. The cold rolling procedure aligns the grain structure of the steel, resulting in improved magnetic permeability and reduced core losses.
Following the cold rolling process, the annealing stage commences, wherein the internal stress within the steel is alleviated, further augmenting its magnetic properties. The steel is subjected to specific temperatures and then gradually cooled to achieve the desired grain structure and magnetic characteristics. Annealing also serves to mitigate the brittleness of the steel, rendering it more pliable and manageable during subsequent manufacturing stages.
Upon the completion of the annealing process, the silicon steel is deftly cut into individual laminations of the requisite size and shape. These meticulously crafted laminations are then adroitly stacked together, forming the foundation of the transformer core. The stacking process ensures the alignment of the grain orientation in each lamination, optimizing the magnetic flux path and minimizing energy losses.
