Cold rolled grain oriented steel

Cold-rolled-Non-grain-oriented steel (CRGO) With demand for the generation and transportation of electrical energy was increasing, one English scientist named Robert A. Hadfield began introduced various elements, creating several iron alloys, and observing the effects of alloying elements on its magnetic and electrical properties. Finally he confirmed that the addition of up to 6.5 wt% silicon yielded the best electrical and magnetic properties. Cold rolled non grain oriented steel, we can also call it CRNGO steel. It is one kind of electrical silicon steel, the grain oriented electrical steel can be divided into two gardes: Semi-processed: it need a QDA treatment, and no organic coating, it is good for samll power transformer, samll rotors Fully-processed:  it has the magnetic fully develop through the mill, which helps it be a good choose for electrical system housing, transformer and motors Depends on different application, we provide a range of insulation c…
