An on-vehicle electronic scale (automatic weighing and metering system) is installed on each molten steel ladle car. The on-vehicle electronic scale of the molten steel ladle car includes a wireless transmitter, a wireless receiver, a junction box, an antenna, a DC battery, a large-screen display, a weighing box, a protection box, etc.; the wireless transmitter, the junction box, the antenna, the DC battery, and the protection box are installed on the molten steel ladle car, the wireless receiver is installed in the central control operation room, and the large-screen display is installed near the operation room. The weight of the molten steel in the on-site molten steel ladle is weighed by a weighing sensor, a junction box, and weighing metering data processing, and is transmitted to the wireless receiver in the central control room through the wireless transmitter. The weighing data guides the production personnel to operate.

[0003] The wireless transmitter, the junction box, the antenna, and the DC battery are installed in the protection box. Since the protection box is not heat-insulating and not pressure-resistant, it is often splashed by molten steel and steel slag, and the protection box is crushed and deformed. In addition, the high temperature causes damage to the electronic components and DC battery in the box. The box and the electrical components and equipment in the box are frequently replaced, the equipment cannot work stably, the data communication is interrupted, resulting in the production data not being received in time and affecting the normal production, and the equipment maintenance cost is high. Generally, the outer shell steel plate of the instrument protection box ordered on the market is made of ordinary carbon steel. This protection box has a thin outer shell and is not heat-insulating inside, which cannot meet the on-site requirements of the molten steel ladle car for steelmaking. Therefore, the technical personnel in the field provide a protection box device for a weighing instrument of an iron ladle car to solve the problems raised in the above background technique.
