The LTS-40E/S Tundish spraying machine represents an advanced integration of a mixing station, pumping mechanism, and application nozzle designed specifically for the application of refractory slurries during the maintenance of tundishes in steel production facilities.
 
This system's architecture, which pairs a Ø250 continuous mixer with a vertical screw pump model 2L7, ensures the creation of a uniform blend of premium refractory compounds. This results in optimal and cost-effective lining of tundishes, which is critical for maintaining seamless operations in steel mills equipped with continuous casting technologies.
 
Operation Mechanism of LTS-40E/S Tundish spraying machine for sale:
Dry, pre-blended slurry mixes are introduced from bulk containers into a storage bin. A fluidizing component paired with a vibrator facilitates a reliable stream of dry ingredients and ensures smooth loading into the continuous mixer. Within this mixer, the dry components encounter a regulated influx of water, transforming into a consistent, high-grade sprayable slurry.

Once prepared, the wet mixture transfers from the continuous mixer to the wet mortar reservoir attached to the screw pump. The design of this reservoir features a funnel geometry along with a centrally aligned pump actuator. A vibrator and transport shaft within the wet mortar container work in tandem to maintain a steady and obstruction-free passage of the slurry towards the intake of the vertically oriented screw pump.

Through pressure-resistant conduits, the screw pump delivers the refractory material to a spray applicator, where it can be applied either by hand or through automated means. This process ensures that the refractory coating is deposited evenly on the interior surfaces of the tundish without waste. The precision of the spraying is managed via the nozzle at the end of the spray apparatus.
 

The specific application of LTS-40E/S Tundish spraying machine is mainly concentrated in the continuous casting process of the steel industry, used to repair and maintain the lining of the tundish. In the continuous casting process, the tundish is a transition container between the molten steel from the steelmaking furnace to the casting mold. The condition of the refractory material inside it has an important impact on the stability of the production process and the quality of the castings. When the tundish needs to be repaired or the lining is replaced, the Tundish Spraying Machine can efficiently spray a new layer of refractory material to ensure that it has good thermal insulation performance and sufficient wear resistance.
