The difference between oriented silicon steel sheet and non-oriented silicon steel sheet
Silicon steel, commonly known as silicon steel sheet or silicon steel sheet, is an indispensable carbon-containing ferrosilicon soft magnetic alloy that is indispensable in the power, electronics and military industries. It is also the most productive metal functional material, and its output accounts for about 1% of the world's steel output. It is a ferrosilicon alloy containing 0.8%-4.8% silicon, which is hot and cold rolled into a silicon steel sheet with a thickness of 1mm or less. · Adding silicon can increase the electrical resistivity and maximum magnetic permeability of iron, reduce coercivity, core loss （iron loss） and magnetic aging. It is mainly used as the core of various motors, generators and transformers.
Method for producing high-grade non-oriented silicon steel by thin slab continuous casting and rolling process
How to use the thin slab continuous casting and rolling process to produce high-grade non-oriented silicon steel, so as to give full play to the advantages of thin slab continuous casting and rolling process, is a technical problem that needs to be solved in the prior art.
Hot-dip galvanizing will become one of the important emerging hot-dip galvanizing markets in the future
Reinforced concrete often causes rusting of steel and peeling of concrete due to external environment; for example, vehicle impact, insufficient protective layer, neutralization of concrete, misuse of sea sand and environmental factors, etc., causing rusting of concrete or immersion of concrete gaps Causes the steel bars to rust.
Effect of Ambient Temperature on Magnetic Properties of Non-oriented Silicon Steel
The effects of different ambient temperatures on the electromagnetic properties of non-oriented silicon steel were studied. The changes of steel loss, magnetic induction and magnetic permeability of 0.35 mm non-oriented silicon with the ambient temperature in the range of 30-120 °C and the content of silicon in the range of 2.0%-3.0% were studied. The results show that when the temperature is raised from 30 ℃ to 120 ℃, the iron loss P1.5/50 decreases by about 4.03%, the magnetic induction B50 decreases by about 6.83%, and the maximum magnetic permeability μm decreases by about 9.36%.
Private enterprise steel PK central enterprises, state-owned steel, where is the road?
The current situation of the Chinese economy and whether the private sector economy has to withdraw from the market stage will be discussed. Many large-scale iron and steel enterprises with large Chinese characters are the leading steels with large volume, cross-border and high starting point. Their advantages are that private small and medium-sized steel enterprises are far behind, and private steel is facing unprecedented challenges.
