Working Principle:

Insert the pull rod from the hot-repair side of the nozzle hole. Rotate the pull rod to block the upper nozzle. Pull the pull rod with a hollow hydraulic cylinder to quickly remove the upper nozzle from the nozzle hole of the base brick. This significantly reduces labor intensity and improves work efficiency.

Product Features:

1. Insertion from the hot-repair side reduces labor intensity.
2. Lightweight and easy to operate. No lifting equipment is required, requiring minimal space.
3. The pull head can be adjusted to accommodate the on-site nozzle and base brick hole expansion requirements.
4. Replacing refractory materials is simple.
5. Core components are made of high-temperature resistant materials, are non-deformable, and offer excellent stability. High success rate and excellent practicality.
