More Information
Summary:The utility model provides a micro-sound marker for steel ladle number identification. The micro-sound marker comprises a micro-sound chip, a shell, a cover plate and a marker antenna, the shell comprises an anti-collision outer shell, an inner shell and a base, and the outer shell is higher than the inner shell; the micro-acoustic chip is a chip with a direct insertion type packaging structure, and the micro-acoustic chip is conductively connected with the marker antenna; the marker antenna is located on the inner side of the inner shell and mechanically connected with the base. And the cover plate covers the top end of the inner shell. According to the utility model, the micro-sound chip is packaged in a direct insertion manner, so that the normal working temperature of the marker can be improved. And the shell is provided with an anti-collision structure, so that external collision can be resisted. And through the design of the cover plate, molten steel sputtering can be prevented, and safe and durable ope
