M111-30P Steel FAQS

What is M111-30P steel?

M111-30P steel is a transformer steel commonly used in the construction of power transformers. This material is known for its high magnetic permeability and low core loss. M111-30P steel is usually produced in sheet form and is available in a variety of thicknesses.

M111-30P steel is an important material for manufacturing power transformers. The material has high magnetic permeability, which allows it to store more energy than other types of transformer steel. Additionally, M111-30P steel has low core losses, which means it transfers energy more efficiently than other types of transformer steel.

How is M111-30P steel formed?

In 1961, based on the introduction of Armco patents, Nippon Steel first trial-produced high magnetic induction grain-oriented silicon steel with AlN+MnS comprehensive inhibitors. Trial production began in 1964 and was named Hi-B, but the magnetism was unstable. After 15 years of continuous improvement, the manufacturing process of Hi-B steel has been perfected day by day, and the Z8H grade was officially produced in 1968. Since 1979, Nippon Steel and Kawasaki have successively produced new grades of 0.30, 0.27, 0.23 and 0.18mm high magnetic induction oriented silicon steel by increasing the silicon content, reducing the thickness of the steel strip and refining the magnetic domain technology. M111-30P steel is one of the new grades of 0.30mm high magnetic induction oriented silicon steel.

What is the iron loss value of M111-30P steel?

The iron loss value is also called the core loss, which refers to the ineffective electric energy consumed when the iron core is magnetized under the alternating magnetic field of ≥50Hz, and is also often called the variable loss, and its unit is W/kg. This kind of ineffective electric energy consumed due to various obstacles to the change of magnetic flux not only loses electric energy through the heating of the iron core, but also causes the temperature rise of the motor and transformer. The iron loss (PT) of electrical steel includes three parts: hysteresis loss, eddy current loss (Pe) and abnormal loss (Pa). The electrical steel plate has low iron loss, which can not only save a lot of electric energy, but also prolong the working time of the motor and transformer, and simplify the cooling device. Since the power loss caused by the iron loss of electrical steel sheets accounts for 2.5%~4.5% of the annual power generation in various countries, the production of electrical steel sheets in various countries always tries to reduce the iron loss, and takes the iron loss as the most important index for evaluating the magnetic properties of products. The iron loss value of the product is used as the basis for dividing the product grade. The maximum iron loss value of M111-30P steel is 1.11W/kg.

What is the thickness of M111-30P steel?

The thickness of 30P series electrical steel is 0.30mm, so the nominal thickness of M111-30P steel is 0.30mm

What is the density of M111-30P steel?

The theoretical density of M111-30P steel is 7.65kg/dm³.

What is the magnetic induction coefficient of M111-30P steel?

The magnetic induction intensity is the number of magnetic force lines passing through the unit cross-sectional area of ​​the iron core, also known as the magnetic flux density, which represents the magnetization ability of the material, and the unit is T. The magnetic induction intensity of the electrical steel plate is high, the excitation current (also called no-load current) of the iron core is reduced, and the copper loss and iron loss are both reduced, which can save electric energy. When the power of the motor and transformer is constant, the magnetic induction intensity is high, the design Bm can be increased, and the cross-sectional area of ​​the iron core can be reduced, which reduces the volume and weight of the iron core, and saves the amount of electrical steel plates, wires, insulating materials and structural materials. The total loss and manufacturing cost of the motor and the transformer can be reduced, and the manufacturing, installation and transportation of large transformers and large motors are beneficial. The minimum magnetic induction coefficient of M111-30P steel is 1.89B.
