Cold rolled non-oriented electrical steel products (CRNGO) can be said to be the earliest and most mature products in the entire silicon steel industry. The manufacturing method is to punch a hot rolled coil into a steel strip, and the silicon content is greater than 2.25%. The electrical steel strip is thoroughly softened and rolled at a low temperature to obtain an excellent magnetic properties, which meet the requirements of the motor stator used in various types of motor.
CRNGO electrical steel products are mainly used for the core of various motor and ballast cores. They are mainly used for the production of motor stator core, variable transformer core, ballast core and other products. According to the standard requirements of GB/T514-2004 Non-oriented Cold Rolling Electrical Silicon Steel and GB/T5193-2003 Thickness and Width Tolerance of Cold Rolling Electrical Silicone Steel Strip, the process size of the concrete product shall be strictly controlled.
In terms of mechanical properties, CRNGO is mainly used to evaluate the yield strength (YS), tensile strength (TS) and elongation (A). The knowledge points of ultimate tensile strength and yield strength should be clearly understood. The ultimate tensile strength (TS) should be greater than 500MPa, while the yield strength (YS) should also be greater than 350MPa. The elongation (A) should be greater than 3%, and some special requirements will require higher elongation (A).
Generally speaking, the higher the grade of the steel strip, the better the performance. In order to meet the requirements of different products, Baogang Cold Rolling Co., Ltd. not only has multiple grades of steel strip products, but also strictly controls the quality of steel strip in accordance with the standards of GB/T, JIS, ASTM and DIN, so as to ensure that customers get corresponding products.
In terms of surface quality and steel strip width, the requirements are also very stringent, mainly involving the deviation requirements of flatness, stripes, waves, water ripples and other properties of the steel strip surface. All of these parameters must be controlled accurately to ensure excellent surface quality.
In a word, Baogang Cold Rolling Co., Ltd. is always committed to providing a variety of excellent non-oriented cold rolled steel products, and providing our customers with the best service. We are willing to cooperate with you sincerely to create a brighter future.
