彩电显像管用耳环是固定显像管并与机壳相连接的零件,要求材料具有良好的冲压性能和一定的表面质量,以便冲压成型及其后的电镀工艺处理。以往它一直依赖进口,故是“七五”期间彩电材料国产化的一个关键金属品种之一。1990年2月,冶金部和机电部联合召开了“彩电用关键金属材料国产化工作会议”,会上通过了“彩电用钢(耳环钢带)国产化”科研协议。最终落实由宝山钢铁总厂进行开发研制。
Color TV tube with earrings is a fixed picture tube and the shell connected to the parts, the material requires a good stamping performance and a certain surface quality for stamping and subsequent plating process. In the past it has been dependent on imports, it is one of the key metals localization of color TV materials during the “Seventh Five-Year Plan” period. In February 1990, the Ministry of Metallurgy and the Electromechanical Department jointly held a conference on localization of key metallic materials for color televisions. At the meeting, the scientific research agreement on the localization of color steel for steel (ear band) was passed. The final implementation by the Baoshan Iron and Steel Plant for development.
