As we know, according to the grain orientation, silicon steel coil is generally divided into grain oriented silicon steel coil and non grain oriented silicon steel coil. Both have distinct properties that make them suit specific applications. Today, let’s learn non grain oriented silicon steel coil first.
Non oriented silicon steel, also known as non grain oriented silicon steel coil or NGO silicon steel coil, is a remarkable type of electrical steel that finds itself in great demand for the creation of electric motors, generators, and transformers. Its magnetic properties, ever so uniform in all directions, render it most suitable for applications where the magnetic field, in its capricious nature, chooses to rotate or change direction with great frequency.
The magnetic permeability of non-oriented silicon steel coil is very high, enabling the effortless conduction of magnetic fields. This attribute proves indispensable in electrical transformers and other electromagnetic contrivances, as it facilitates efficient energy transfer.
Another virtue of non-oriented silicon steel coil lies in its low core loss. Core loss, the dissipation of energy in the form of heat when a magnetic field is applied to a material, is minimized by this coil, leading to enhanced energy efficiency.
Non-oriented silicon steel coil also boasts commendable electrical conductivity. This quality ensures the smooth flow of electric current through the material, making it ideal for applications that demand high conductivity, such as electric motors and generators.
Non-oriented silicon steel coil exhibits an exceptional ability to withstand high temperatures. This property guarantees the material’s stability and the preservation of its magnetic properties even in the most extreme operating conditions.
Lastly, non-oriented silicon steel coil shows great formability and workability. It can be effortlessly molded and processed into desired shapes, providing versatile manufacturing options and customization tailored to specific requirements.
Non-oriented silicon steel coils, with their exceptional magnetic properties and minimal core losses, find wide-ranging applications across various industries. They can be used in:
1. Electrical transformers. The electrical transformer heavily relies on non-oriented silicon steel coils to facilitate the efficient conduction of magnetic flux. These coils, with their low core losses and high magnetic permeability, prove ideal for transformer cores, ensuring minimal energy wastage during the transmission of power.
2. Electric motors and generators. Electric motors and generators owe their enhanced performance to the utilization of non-oriented silicon steel coils. By minimizing eddy currents and hysteresis losses within the cores, these coils significantly reduce energy losses. Consequently, the overall efficiency and power output of these devices are greatly improved.
3. Inductors and chokes. In electronic circuits, non-oriented silicon steel coils find indispensable applications in inductors and chokes. These coils play a vital role in storing and releasing energy through magnetic fields, thereby ensuring the smooth and efficient functioning of electronic devices.
4. Magnetic cores for various electronic devices. Non-oriented silicon steel coils serve as the magnetic cores for a wide range of electronic devices, including sensors, actuators, and relays. These coils provide the essential magnetic properties necessary for optimal performance and reliability of these electronic components.
5. Automotive industry. The automotive industry extensively incorporates non-oriented silicon steel coils into various applications. These coils are utilized in electric vehicle motors, hybrid vehicle systems, ignition systems, and other automotive electronic components. Their high magnetic permeability and low core losses contribute significantly to improved efficiency and performance in these automotive applications.
The manufacturing process of non-oriented silicon steel coil involves several important steps that ensure the production of high-quality coils. They are:
The raw material undergoes rigorous quality checks to ensure it meets the required specifications. It is then subjected to a thorough cleansing, meticulously processed, and shaped into sheets, poised for the subsequent stages.
The sheets are carefully heated to soaring temperatures and guided through a series of rollers, purposefully reducing their thickness. This meticulous process serves to enhance the material’s magnetic properties and elevate its electrical conductivity. Moreover, the hot rolling stage facilitates the alignment of the crystal structure within the silicon steel, thereby resulting in an improved magnetic performance.
Following the hot rolling stage, it undergoes a subsequent phase known as cold rolling, which further diminishes its thickness and refines the material’s grain structure. Cold rolling serves to enhance the mechanical properties of the steel, whilst simultaneously improving its dimensional accuracy. Once cold rolling is complete, the sheets are subjected to the gentle embrace of annealing, a process that alleviates internal stresses and restores the material’s magnetic properties. This delicate procedure is conducted within controlled atmospheres, to achieve the desired electrical characteristics.
Upon the completion of the annealing process, the silicon steel sheets are adorned with a coating of insulation material. This meticulous coating serves the purpose of impeding the flow of eddy currents and minimizing energy losses. The insulation coating is applied with great care, ensuring uniformity and steadfast adherence to the sheets. Subsequently, the sheets are cut into coils of precise dimensions.
Non-oriented silicon steel coil offers several advantages and benefits that render it a preferred choice in various industries. These advantages include:
The utilization of non-oriented silicon steel coil is designed to minimize energy losses during the transformation of electrical energy. Its low core losses and high magnetic permeability result in enhanced energy efficiency, rendering it an ideal selection for employment in electrical machines and transformers.
The implementation of non-oriented silicon steel coil facilitates the reduction of core losses and heat generation. This is achieved through its high resistivity and low hysteresis loss properties, which effectively diminish energy dissipation and heat buildup. Consequently, the coil operates at lower temperatures, leading to an improved performance and an extended lifespan of the equipment.
Non-oriented silicon steel coil offers an augmented performance and reliability owing to its consistent magnetic properties and uniform grain structure. This ensures a stable and efficient operation, even under varying load conditions and frequencies. The coil’s high magnetic saturation and low magnetostriction further contribute to its reliable performance, making it suitable for critical applications.
While non-oriented silicon steel coil may possess a higher initial cost in comparison to other materials, its long-term cost-effectiveness becomes evident. The coil’s energy-efficient nature leads to reduced electricity consumption, resulting in lower operational costs over time. Additionally, its durability and reliability minimize maintenance and replacement expenses, making it a cost-effective choice in the long run.
Non-oriented silicon steel coil aligns with the principles of sustainability and green technologies. Its energy-efficient properties reduce carbon emissions and contribute to a greener environment. Furthermore, the coil’s recyclability ensures minimal waste generation and promotes the circular economy, making it an environmentally friendly option for industries.
