Continuous caster tundish car is special vehicles that support and carry tundish. The continuous casting process requires that the tundish must be preheated (usually preheated to 1100 ℃) before pouring steel, and then can enter the steel pouring position to receive molten steel. In the process of entering the steel pouring position, in order to protect the nozzle, the tundish must be raised. After reaching the pouring position, the raised tundish must be adjusted so that the nozzle is aligned with the center of the mold. Therefore, the tundish truck must have the functions of walking, lifting, and lateral fine-tuning.
The tundish car consists of the following devices: running device, lifting device, fine-tuning device, long nozzle loading, and unloading device, weighing device, ladle operating platform, power supply towline chain, ladle sliding nozzle hydraulic station, mold slag feeding device, supply gas system, oil supply system, overflow tanker, etc.
According to the process layout and operation requirements, tundish cars are available in floor type, semi-door type, overhead type, and other forms.
Tundish car is equipped with AC electrical motor with variable frequency, hydraulic tundish lifting, and tundish horizontal position centering so that protecting casting and tundish nozzle centering can be easily operated.
The Performance and Structural Description
The main function of the tundish car was carrying and transportation among the cans, in the casting process can quickly replace the intermediate tank to ensure the smooth progress of continuous casting, in addition, in the event of an accident can quickly leave the casting Tundish bit.
Tundish cars from the middle of the mainframe, walking mechanism, manually transferring the composition of the fine-tuning device. In order to facilitate the intake of tin in the middle, running organizations adopt VVVF to achieve fast, slow transmission, on the longitudinal and lateral horizontal fine-tuning of, the structure of the form structure using high and low legs.
All the energy and signal transmission media cable reel with external connections. Side of the tundish car with pouring insulation panels, to prevent heat radiation tundish in order to improve the operating conditions.

Technical Requirements for Tundish Cars
The tundish car is arranged on the pouring platform of the continuous casting machine and is used to transport the dried and baked tundish from the preparation position to the pouring position. Using the horizontal fine-tuning and lifting mechanism, the nozzle of the tundish can be accurately centered and inserted into the mold for pouring. When the pouring is over or an accident cannot be poured, the tundish car can quickly return to the ready position for tundish change or accident handling. In order to ensure continuous casting of multiple furnaces, each continuous casting mechanism is equipped with two tundish trucks, one for online casting and the other for preparations such as baking.
The Technical Requirements Are as Follows:
1. The tundish car is required to run smoothly, reliably, and accurately.
2. It is convenient for the loading and unloading of the tundish and the observation and operation of the tundish.
3. It is required that the nozzle of the tundish and the upper mouth of the crystallizer are conveniently and accurately aligned.
4. The frame must have sufficient strength and rigidity to ensure good performance under thermal load and set up corresponding protective covers to prevent damage to related equipment caused by thermal radiation and molten steel splashing.
5. When using protective pouring and automatic control, the tundish lifting and the weighing device should be set up.
