What Is Silicon Steel Coil Application?

2025-11-01

Because of its outstanding magnetic permeability and low loss characteristics, Silicon steel, a critical electrical material, is frequently found in transformers, motors, and power equipment. Non-oriented silicon steel and oriented silicon steel are the two varieties of silicon steel; each has particular features and applications. The coil slitting line, a vital piece of machinery for making superior silicon steel strip, is especially important in the processing of silicon steel strips. The properties of silicon steel, the criteria for coil cutting devices during manufacture, and its major uses will all be covered in this piece.

 

Characteristics of Silicon Steel

Silicon steel is primarily composed of iron and a small amount of silicon. Adding silicon dramatically raises the resistivity of the steel and lowers magnetic losses, hence silicon steel is becoming more often used in the electrical sector. Superior magnetic permeability of silicon steel can significantly boost the energy efficiency of transformers and motors.

Low loss characteristics of silicon steel in power equipment help to minimize energy waste and boost general energy efficiency. For this reason, silicon steel is considered a fundamental material in the electrical industry.

Silicon Steel Strip Requirements for Coil Slitting Machine

1. Material requirements for coil slitting machine

KINGREAL SLITTING engineers follow national standards or client-specified technical requirements precisely when processing silicon steel with a coil slitting machine. This technique is essential to make sure the coil slitting line can handle silicon steel products with low loss and great magnetic permeability. 

The coil slitting line can be fitted with a laminating device to properly stop scratches caused by the slitting process's blades guarantee the finished silicon steel strip has a smooth, faultless surface. The laminating device minimizes material damage during processing, minimizing defects such as scratches, dents, oxidation, and oil stains.

The coil slitting line's design takes into account the characteristics of silicon steel, enabling higher precision and efficiency during cutting.

 

2. Dimensional accuracy for coil slitting line

KINGREAL SLITTING coil slitting machine can be modified to fit particular project demands, hence satisfying the unique manufacturing needs of KINGREAL SLITTING customer and so guaranteeing that the width, thickness, Length and slitting of the silicon steel strip match the standards required. Managing dimensional deviation during the slitting process is quite important. KINGREAL SLITTING engineers utilize sophisticated design and advanced processes to ensure that dimensional deviations remain within reasonable limits.

This precision control applies not only to the cutting of individual silicon steel strips but also to the handling of the entire coil. Through optimized coil slitting line design, KINGREAL SLITTING ensures that each silicon steel strip meets customer requirements in subsequent processing and application.

In high-precision applications, such as transformer and motor manufacturing, dimensional accuracy requirements are even more stringent. The high-precision cutting capabilities of the coil slitting machine ensure that each component performs optimally, thereby improving the quality of the final product.

 

3. Surface quality for coil slitting line

During the slitting process, the coil slitting line must strictly control surface quality to ensure a smooth and even silicon steel strip. KINGREAL SLITTING equips coil slitting machines with high-quality blades, typically made of 42CRMO. This blade is sufficiently hard and wear-resistant to maintain its sharpness during cutting, ensuring a burr-free surface on the cut silicon steel strip.

To keep optimum cutting outcomes, coil slitting machine blades have to be frequently maintained and replaced. Cutting quality is directly impacted by blade wear, which can cause surface flaws.

 

4. Edge straightness for coil slitting machine

Any noticeable defects such as curling, burrs, and cracks will negatively impact product performance. To ensure the quality of the final product, KINGREAL SLITTING engineers carefully considered edge straightness when designing the coil slitting line.

In actual production, edge straightness control involves multiple components of the coil slitting machine, including blade installation, cutting angle adjustment, and material feeding method. Through reasonable design and optimized process flow, the coil slitting machine can achieve high levels of edge straightness, ensuring that each silicon steel strip maintains consistency during subsequent processing.

 

5. Packaging requirements for coil slitting line

To shield the product from harm during storage and transit, the silicon steel strip should be packed following customer requirements after cutting. Appropriate packaging not only protects the product but also enhances customer satisfaction. After cutting narrow strips, KINGREAL SLITTING coil slitting lines can be rewound through a reel for easy long-distance transportation.

When selecting packaging materials, KINGREAL SLITTING ensures that all materials meet environmental standards to avoid contamination and corrosion on the product surface. Through appropriate packaging design, friction and collisions during transportation are effectively prevented, preserving the surface quality of the silicon steel strip.

In addition, KINGREAL SLITTING can equip the coil slitting machine with a coil packaging line for enhanced automation. This not only improves production efficiency but also allows for labeling and packaging of the coils, facilitating identification and tracking during subsequent logistics and inventory management.

 

Applications of Silicon Steel

Silicon steel has a wide range of applications and is primarily categorized into two types: non-oriented silicon steel and oriented silicon steel.

 

Coil slitting line for CRNGO

Non-oriented silicon steel does not require a special pressing process to adjust the crystal orientation, making its production process relatively simple and cost-effective. Non-oriented silicon steel exhibits omnidirectional magnetic properties, making it suitable for applications where magnetic flux requirements are less demanding. Non-oriented silicon steel strips produced by KINGREAL SLITTING silicon steel slitting machines are typically used in electric motors and generators with moving parts.

The silicon content of non-oriented silicon steel typically ranges from 0.5% to 3.25%. The addition of aluminum further increases resistivity and lowers the recrystallization temperature. This type of silicon steel is primarily used in a variety of large rotating equipment, including electric motors, generators, and alternators, and is popular for its excellent performance and cost-effectiveness.

 

Coil slitting line for CRGO

The production process for oriented silicon steel is more complex, requiring strict control of composition and processing. The final texture formation process involves a series of meticulous machining and annealing operations to ensure a stable single-phase structure. This type of silicon steel typically contains 3.25% silicon, which effectively increases resistivity and reduces magnetostriction.

Grown silicon steel strips cut by KINGREAL SLITTING coil slitting machines are widely used in equipment such as transformers and generators. When selecting material for transformers, factors such as cost-effectiveness, power rating, noise level requirements, loss requirements, and core size all influence the material grade and specification. For generators, oriented silicon steel is widely used in steam turbines and hydro turbines to ensure power generation efficiency and stability.
