本发明系硅钢生产特别是含2—4％硅晶粒取向硅钢生产的专利。硅钢是广泛应用在电气设备中,因为它有高的导磁率、高的电阻和低的磁滞损失。在制造过程中需要严格控制成份,因为加入铁中的几乎全部的合金元素都对磁性有不利的影响。例如:杂质像氮、氧、硫和碳,在晶粒点阵中引起位错,形成有害的内应力。所有元素中影响最坏的是碳。在制造过程中采用具有较高含碳量的硅钢是具有一定优点的并在以后加工为成品时钢能脱碳到具有好的电磁性能的低碳水平。其优点包括:
The invention is the production of silicon steel, especially with 2-4% silicon grain oriented silicon steel production patent. Silicon steel is widely used in electrical equipment because of its high magnetic permeability, high electrical resistance and low hysteresis loss. Strict control of the ingredients is required in the manufacturing process because almost all of the alloying elements added to the iron have an adverse effect on magnetism. For example: Impurities like nitrogen, oxygen, sulfur and carbon cause dislocations in the lattice of grains, creating unwanted internal stresses. The worst of all elements is carbon. The use of silicon steel with a higher carbon content in the manufacturing process has some advantages and can be decarburized to a low carbon level with good electromagnetic properties when processed into finished products later. Its advantages include:
