Non-oriented electrical steel is a special steel used in the manufacture of electrical equipment such as motors, transformers and generators. Its main features are low magnetic permeability and high resistivity, which can effectively reduce eddy current loss and Joule heat loss. In this article, we will discuss the development and product characteristics of non-oriented electrical steel.

As an important electrical material, cold rolled non oriented electrical steel plays a key role in the power industry, energy industry and electric vehicles. With the growing global demand for renewable energy and efficient energy conversion, the cold-rolled non-oriented electrical steel industry is facing great opportunities for development.

Grain-oriented silicon steel is a special electrical steel used in the manufacture of motors, transformers and other electromagnetic equipment.

Cold-rolled oriented silicon steel is a type of electrical steel commonly used in equipment such as transformers and electric motors in the power industry.

Iron core punching is one of the important parts of motor manufacturing. Punching manufacturing workload is the largest, the most stringent technical requirements, the highest requirements for the mold, is an important factor affecting economic benefits, so we must pay attention to the study of iron core punching manufacturing process and related mold structure issues.

UHV mainly refers to the AC power grid of 1000kV and above or the DC power grid of ±800kV and above, which has the advantages of long transmission distance, large capacity, low loss, less land occupation, and transmission capacity of up to 2.4 times to 5 times that of 500kV UHV power transmission. It is called "power highway" and belongs to the "new infrastructure" smart energy infrastructure.

The China Federation of Logistics and Purchasing released its global manufacturing purchasing managers' index for November. The index has remained below 50% for 14 consecutive months, and the global economy continues to weaken.

Problems such as exhaust pollution and oil safety have prompted new energy vehicles to become the mainstream of future motor vehicles, and high-grade non-oriented electrical steel, as an important soft magnetic material, is widely used in high-end home appliances, new energy vehicle drive motors and efficient industrial motors and other fields.

Grain oriented electrical steel is also known as cold rolled oriented silicon steel. Cold-rolled directional silicon steel contains 2.9%~3.5% Si. The crystal structure of the steel plate refers to cold-rolled electrical steel with certain rules and directions.
