摘要： The present invention relates to a method of coloring a tension coating layer of an electric steel sheet by adding a semiconductor, and an electric steel sheet colored by the method. More particularly, the present invention relates to a method of coloring an electric steel sheet, the method including: adding 1 to 3 wt % reactive semiconductor compound and 1 to 3 wt % cadmium oxide to a tension coating material of an electric steel sheet with respect to a total weight of the coating material, by a weight ratio of 1:1; coating the tension coating material onto the electric steel sheet; and heat-treating the coated electric steel sheet at a temperature of 150 to 1200 °C for 2 to 200 seconds, and an electric steel sheet colored by the method. That is, the present invention relates to a technology of hiding surface detects formed under the tension coating layer of the electric steel sheet by virtue of coloring of the electric steel sheet when SiO and semiconductor particles inside a tension coating material are grown by adding a semiconductor to the coating material of the electric steel sheet and heat-treating the coating material.
摘要翻译：本发明涉及一种通过添加半导体对电工钢板的张力涂层着色的方法和通过该方法着色的电工钢板。更具体地说，本发明涉及一种对电动钢板着色的方法，该方法包括：向电动钢板的张力涂层材料中加入1〜3重量％的活性半导体化合物和1〜3重量％的氧化镉，至涂料的总重量，重量比为1:1; 将张力涂层涂布在电工钢板上; 在150〜1200℃的温度下对涂覆的电工钢板进行2〜200秒的热处理，通过该方法着色的电工钢板。也就是说，本发明涉及在通过添加半导体的生长中的SiO和半导体颗粒在生长张力涂层材料之前，通过电工钢板着色而形成在电工钢板的张力涂层下形成的表面检测技术与电工钢板的涂布材料进行热处理。
