[0002] With increasing awareness of reducing pollutant emissions and energy consumption, energy-saving requirements have been put forward for all aspects of molten iron transportation. Currently, in most large steel enterprises in China, molten iron is typically transported from the mixing car to the designated location within the steel plant by ladle cars after arriving at the plant. For example... Figure 1 The illustrated molten iron ladle car 5 includes a frame 51 with a molten iron ladle 6 movably mounted in the middle of the frame 51. Because the molten iron ladle is transported open, it generates a large amount of smoke and dust during transport, causing environmental pollution. Furthermore, heat loss is unavoidable during open transport. Additionally, the short-distance open transport of molten iron ladle cars within steel mills presents a complex environment and a risk of tipping over, potentially leading to molten iron spills. Currently, some molten iron ladle cars are equipped with covers, but these generally suffer from problems such as large space requirements, complex structures, and high costs. Utility Model Content

The control device is connected to a communication device, and a camera device connected to the control device is installed on the molten iron ladle car 5. The camera device transmits on-site images to the control device and the communication device, which in turn transmits them to the remote control device. The operator issues operation commands to the control device through the remote control device, and the control device performs relevant opening or closing operations according to the received commands.
