摘要:
There are provided a coating composition for siliconizing, and a method for manufacturing a high silicon electrical steel sheet using the same. The coating composition includes: a Fe-Si-based composite compound sintered powder having a grain size of - 325 mesh and containing 20 - 70 % silicon by weight; and a colloidal silica solution containing 15 - 30 part by weight of silica solid matter with respect to 100 part by weight of the sintered powder.
摘要:
A method of manufacturing hot rolled silicon steel sheets, which consists of the steps of heating a silicon steel slab at a high temperature so as to roughly hot roll the same, and thereafter subjecting the resultant product to finishing hot rolling, wherein the rolling on a first stand, which is conducted during the finishing hot rolling, is done under the conditions satisfying the following expression: (TF1-TF0)/{(TF1-tF2)/2}
摘要:
Provided is a method for producing a grain-oriented electrical steel sheet with which it is possible to achieve both favorable iron loss and high productivity. In groove formation for magnetic domain refinement, a resist comprising a photosensitive resin is applied, and exposed and developed to thereby form a linear-shaped ferrite exposed section. In electrolytic etching that is subsequently performed, a current density ρ=I/S with respect to the exposed base metal section is 7.5 A/cm2 or higher, where I is a current supplied to an electrode and S is the surface area of the exposed base metal section in a steel sheet surface of the same surface area as the electrode.
