The working principle of the HWTS-40E/S refractory shotcrete machine for tundish is carefully designed. Initially, the dry premixed slurry is loaded into the hopper from the big bag. A fluidization device and a vibrator ensure the continuous flow of dry materials into the continuous mixer and ensure safe and effective feeding. In the mixer, dry materials are carefully mixed with precisely adjustable water quantity to form a high-quality spray slurry with consistent texture and quality.

Subsequently, the mixed wet material enters the wet mortar hopper of the screw pump from the continuous mixer by gravity. The funnel hopper is equipped with a concentric pump drive device, which works together with a vibrator and conveying shaft to ensure the smooth and uninterrupted flow of mud into the suction port of the vertically installed screw pump. Then, the screw pump transports the refractory to the spray gun through the pressure-resistant hose for use.

The application of refractory materials can be manual or fully automatic, and there is no waste of materials, thanks to the spraying robot, which applies materials to the inner wall of the tundish in a uniform layer. The spraying process is controlled by the nozzle to ensure uniform and effective coverage, making the HWTS-40E/S refractory shotcrete machine for tundish an indispensable tool in the steelmaking process.
