Tundish spraying plant
Tundish spraying plant is a specially designed equipment system for spraying refractory materials onto the inner wall of the tundish. Its main functions include:
Repairing refractory lining: During the continuous casting process, the refractory lining of the tundish will gradually wear out due to the erosion of high-temperature molten steel. Through the spraying device, new refractory materials can be evenly sprayed onto the worn parts, thereby repairing the lining and extending the service life of the tundish.
Pre-spraying protection: Before the new tundish is put into use, a dense refractory protective layer is formed on its inner wall through the spraying device, which can effectively prevent the direct erosion of the refractory lining by high-temperature molten steel and improve the high-temperature resistance and service life of the tundish.
Tundish spraying plant working principle:
Refractory preparation: According to the use conditions and requirements of the tundish, select suitable refractory materials and prepare them into slurry or granular materials suitable for spraying.
Spraying equipment debugging: Debug the spraying equipment to ensure that the spray gun, conveying pipeline and other components work normally, and that parameters such as spraying pressure and spraying speed meet the process requirements.
Spraying operation: The prepared refractory material is transported to the spray gun through the spraying equipment, and it is evenly sprayed on the inner wall of the tundish by high-pressure gas or mechanical force. During the spraying process, the spraying parameters can be adjusted as needed to obtain the best spraying effect.
Drying and curing: After spraying, let the refractory material dry naturally or heat and dry on the inner wall of the tundish. The dried refractory material will gradually solidify to form a solid refractory protective layer.

Tundish spraying plant is mainly used in the following scenarios:
Steel metallurgical continuous casting production line: In the steel metallurgical industry, the continuous casting production line is one of the main equipment for producing steel. As a key component of the continuous casting production line, the performance of the refractory lining of the tundish directly affects the operating efficiency and product quality of the continuous casting production line. Therefore, it is of great significance to use the tundish spraying plant to spray repair or pre-spray protection on the tundish.
Other high-temperature industrial fields: In addition to the steel and metallurgical industry, the tundish spraying plant can also be used in other industrial fields that require high-temperature refractory protection, such as glass manufacturing, ceramic manufacturing, etc. In these fields, there is also a need to spray refractory materials on the inner wall of high-temperature containers or equipment.

Tundish spraying plant has the following advantages and characteristics:
High efficiency: The use of automated spraying equipment can greatly improve the spraying efficiency and shorten the repair or pre-spraying cycle.
Uniformity: By accurately controlling the spraying parameters and the moving trajectory of the spray gun, it can ensure that the refractory material is evenly distributed on the inner wall of the tundish to form a dense refractory protective layer.
Flexibility: According to the use conditions and requirements of the tundish, suitable refractory materials and spraying parameters can be selected to meet the needs under different working conditions.
Environmental protection: During the spraying process, effective measures can be taken to reduce the emission of dust and exhaust gas and reduce pollution to the environment.

Tundish spraying plant has broad application prospects and important value in the steel and metallurgical industry. With the continuous advancement of technology and continuous optimization of processes, its performance and application range will be further expanded and improved.
