The use of electrician pure iron:
1.Electrician Pure Iron various types of Relay Cores,Armature,Yokes in electrical appliances and telecommunications.
2. Coil Soft Iron used for turning and focusing magnets of high-energy accelerators, electro-acoustics, solenoid valves, electromagnet cores of magnetic separation equipment, etc.
3. Electromagnet Pure Iron used for high-resolution magnet pole heads on analytical instruments, electromagnetic separators and geophones in geological instruments, focusing magnets and scanning electromagnetic lenses for electron microscopes, aircraft automatic control components, pole heads for magnetizers, etc.
4. The iron core and shell used for DC motors.
5. Electrical appliances or magnetic parts used in automobiles and lathes.
6. Shielding materials used for all kinds of magnetic shielding covers or shielding boxes that require high shielding equipment.
The characteristics of electrical pure iron:
1-Good electromagnetic performance: low coercivity, high permeability, high saturation magnetic induction, stable magnetism and non-magnetic aging.
2-The smelting process of electromagnetic pure iron series adopts hot metal pretreatment, RH refining, electromagnetic stirring and other processes. The interior is dense and uniform, with low gas content and low carbon content in the finished product.
3-Good cold and hot processing performance:Electrician Pure Iron cold processing can meet the process requirements of turning, piers, punching, bending, drawing, etc., hot processing, such as re-forging and re-rolling, the sensitivity of red brittleness is small, and it can be guaranteed in a larger temperature range Processing within.
4-Good surface quality: good welding and electroplating performance.
5-High dimensional accuracy: ultra-precision cold-rolled plates can be provided, such as thick plates ≤1.5mm, and the thickness tolerance can be guaranteed ≤±0.01mm.
Which is better the coercive force of the relay ferromagnetic material large or small?
Coercive force of Electrician Pure Iron means that the magnetic induction intensity B does not return to zero when the external magnetic field returns to zero after the saturation magnetization of the magnetic material. Only by adding a certain magnitude of magnetic field in the opposite direction of the original magnetization field can the magnetic induction intensity return to zero. The magnetic field is called the coercive magnetic field, also known as the coercive force.
The intensity of the external magnetic field opposite to the original magnetization direction must be added to make the magnetized ferromagnetic material lose its magnetism. It is not only related to the properties of ferromagnetic substance, but also depends on the original magnetization intensity of ferromagnetic substance. When manufacturing the Electromagnet soft iron core or electromagnet of the transformer, it is necessary to choose materials with low coercivity (such as soft iron, silicon steel, etc.) to make the magnetism disappear as soon as possible after the current is cut off. When manufacturing permanent magnets, it is necessary to choose materials with high coercivity (such as AlNiCo, etc.) in order to preserve the magnetism as much as possible and prevent it from disappearing.
What’s the latest technological design of the armature?
The armature of the relay designed by us aims to solve the technical problem that the flatness of the armature in the prior art cannot meet the requirements of use.
To achieve the above purpose, the relay armature we designed includes an armature body. The upper end of the armature body is provided with a hook. Both sides of the armature body are provided with buckle grooves. The front of the armature body is provided with a first contact piece and a second contact piece. , The second contact piece is arranged below the first contact piece, the first contact piece is arranged below the hook, the armature body is provided with a plurality of fixing holes penetrating the front and rear ends of the armature body, and each fixing hole is arranged in the first contact Between the sheet and the second contact sheet, the front and back sides of the armature body are provided with a plurality of interlaced embossments.
We are a new type of relay armature with one of the following technical effects: when in use, the armature is connected to the knife edge of the yoke of the relay through the buckle slot, the yoke of the relay and the first contact piece are attached to each other, and the relay is pulled The spring is connected to the hook. After the electromagnetic force disappears, the tension spring of the relay pulls the hook to reset the armature body. The fixed hole is used to install the movable reed of the relay. The movable reed of the relay is attached to the reverse side of the armature body. , The second contact piece arranged on the front side of the armature body and the iron core of the relay are attached to each other. Because the front and back sides of the armature body are provided with interlaced embossing, the armature body and the movable reed and the first contact piece are less And the contact area of the second contact piece improves the flatness of the armature body, thereby improving the stability performance of the relay.
