The electric arc furnace (EAF) rotary refractory gunning machine is mainly used for rapid and efficient gunning operations when the refractory lining on the inner wall of the electric steelmaking furnace is damaged, so as to ensure the continuous and efficient operation of the electric steelmaking furnace.
Rapid repair
It can perform refractory gunning during the interval between tapping and charging of the electric steelmaking furnace. Typically, the time window for repairing damaged refractories is only 10–30 minutes, thus minimizing downtime caused by maintenance.
High-temperature adaptability
It can continuously perform gunning operations at a high temperature of 200℃ for more than 30 minutes, adapting to the high-temperature environment of electric steelmaking furnaces.
Flexible adjustment
The spray nozzle can rotate vertically in the horizontal plane to adjust the height of the target position, and the working head can rotate around its vertical center line to achieve all-round gunning.
Enhanced adhesion
The atomized water is mixed with refractory materials through a water-material mixer, increasing the adhesion rate by 70–85%.
Cooling and protection
High-pressure cooling air is introduced into the main body, working head connection base and working head, and thermal insulation materials are installed to protect the equipment and components from working normally in high-temperature environments.
In summary, the EAF rotary refractory gunning machine plays a key role in the steelmaking process. It can effectively maintain the refractory lining on the inner wall of the electric furnace and guarantee the continuity and efficiency of steelmaking operations.
