HX Longevity High-tech Hot Ceramic Gunning Mix
For gunning repair, bulk materials are conveyed by air, sprayed to the part to be repaired by a spray gun and attached to the surface of the part to be repaired to a certain height, so that the firebrick lining is unnecessarily re-built, rebuilding of the furnace lining is realized on the remained brick lining or furnace shell, and the furnace shape is restored. The materials have the characteristics of good integrity, long service life and capability of delaying the lining-changing repair time.
The company has set up a special team for developing the blast furnace lining remote control wet method jetting lining technology. By the cooperation of a wet method spray machine and a remote control spray manipulator, the lining of the blast furnace is constructed by remote control thermal state jetting in lost time on the premise of not stopping the furnace, so that the gunning technology completes the big span from the semi-dray method to the wet method, the cold state to the thermal state and the pre-mixing type gunning to the gel combination gunning, and up to now, the gunning technology has been applied to the repair of gas pipes, ascending pipes and descending pipes, particularly the thermal state jetting repair of hot air pipes, and the non-obstacle smooth wind restoration is also realized, and the technology has reached the intentionally advanced level.
Compared with the traditional stopping-furnace maintenance, the technology has the following advantages:
1. Uniform and compact spraying and high strength;
2. No dust in spraying and low recurrent magnitude;
3. Convenient construction, low time consumption and short production time;
4. Long service life of the blast furnace and the hot air furnace, and cost reduction;
5. High construction safety
