Should the suction of Shutting Magnet meet the standard?

The most important and fundamental aspect of high-quality Shuttering Magnet is to ensure that the suction force meets the standard.

Do you know that the suction of the 800 kg magnetic box you purchased is really 800 kg? Is the suction force of the magnetic box you purchased really the same as the suction force value specified in the contract?

The following video shows the suction detection data tested by our company using professional testing instruments:

Analysis of the reasons for demagnetization of Shutting Magnet?

Material：

(1) Magnet: The magnet is the core raw material of the shuttering magnet. For the shuttering magnet, there are two main properties that are crucial:

①Remanence(Br): First magnetize the ferromagnetic material and then remove the magnetic field. The remaining magnetization intensity on the magnetized ferromagnet directly affects the suction of the shuttering magnet. The higher the magnet performance, the greater the Br.

②Coercive force (Hcj):Intrinsic coercivity is a major indicator of the ability of a permanent magnetic material to resist external reverse magnetic fields or other demagnetizing effects to maintain its original magnetization state. It directly affects the degree of decay of the magnet performance when it is affected by the external environment (such as reverse magnetic field, high temperature, etc.). The larger the Hcj, the stronger the resistance to decay.

The performance parameters of the magnet used by Zhangzhou LSC Magnetics Co.,Ltd. meet the GB/T 13560-2017 "Sintered NdFeB Permanent Magnet Materials" standard requirements. Hcj of N35 is not less than 12KOe, Br is not less than 12.1KGs; Hcj of N50 is not less than 13.9KOe, Br is not less than 12.1KGs.

Magnetic grade inspection equipment:

The magnetic surface is uneven and cannot fit tightly with the Formwork. Our company provides a solution.

① The bottom of the magnetic box inevitably adsorbs attachments such as iron wires and debris on the mold table during operation, resulting in a decrease in the suction force of the magnetic box during operation. For this purpose, our company has developed a magnetic box cleaning machine specifically for cleaning the bottom of magnetic boxes to solve this problem.

② On the other hand, due to structural reasons, if the production process is not well controlled, the magnetic block itself may also cause misalignment of the iron bars (uneven suction surface), resulting in a decrease in magnetic box suction.

Our Shutting Magnet has added stainless steel pads between the magnetic core and the magnetic switch, increasing the contact area between the magnetic core and the magnetic switch, preventing unevenness inside the magnetic core during the Shutting Magnet switching process, and avoiding a decrease in Shutting Magnet suction force.

During the leveling process of our magnetic block, the stainless steel locking screws inside the magnetic block use a standard fixed torque wrench, set the torque value, and stop when the fixed torque value is reached, so that the torque of each screw is the same, ensuring the tightness and uniformity of the magnetic block and extending its service life.

The magnet body inside the magnetic block is damaged.

The physical properties of sintered neodymium iron boron materials are hard, brittle, fragile, and prone to corrosion, so the magnet cannot be struck with external force and the coating on the surface of the magnet cannot be damaged. If the magnet inside the magnetic block breaks and the body is damaged, the suction force of the magnetic block will decrease.

So when assembling magnets and iron bars into magnetic blocks, the surface of the magnet should be as low as possible below the plane of the iron bar to effectively avoid impact, and the magnet itself also needs a certain protective layer to prevent damage and corrosion to the body.

In order to protect the magnet body, our company adopts the latest technology to cover each magnet with a stainless steel ring, and through welding and tapping, the stainless steel ring and magnet are tightly adhered:
