Background

The tundish car is used as a transport device for carrying and transporting the tundish in a continuous casting production workshop, is mainly arranged above a casting platform, and walks between a casting position and a baking station by adopting an iron plate track paved in a field. In order to align the tundish nozzle to the mould at the pouring location, manufacturers are usually provided with fine adjustment of the travelling direction and manual adjustment in the transverse direction on board the vehicle. In addition, in order to realize the quick replacement of the tundish, the tundish car is generally designed with two running speeds, namely a quick running speed and a slow running speed, especially at the moment of speed switching of the tundish car, due to the inertia effect generated by speed change, the tundish is overflowed and splashed to a certain extent in front of the car or behind the car, so that a small amount of tundish is always accumulated on an iron plate track on the ground, and in order to prevent the occurrence of derailment accident of the tundish car due to track adhesion, the tundish car is manually cleaned at an irregular period according to accumulation conditions. However, the cleaned steel plate tracks are always concentrated in the same area, and the general spilled splashing tundish (such as high-temperature molten steel) can cause different degrees of damage to the steel plate tracks after being piled up for many times, and when severe, the steel plate tracks need to be replaced by stopping the machine, so that the labor intensity of maintenance personnel in a factory can be increased, and the normal production of the whole workshop can be influenced.
