Description

Technical Field

[0001] The utility model relates to the field of nonferrous metals, in particular to a device suitable for spraying refractory materials. Background Art

[0002] The water jacket at the bottom-blowing furnace mouth reaches a high temperature of approximately 1250°C during production. Circulating water is required to cool the jacket during operation, but internal water pipes fail to fully cool the jacket, leading to localized burnout. If leaks in the jacket are not detected promptly during bottom-blowing furnace production, water entering the furnace and contacting the high-temperature melt could easily cause explosions, posing a significant safety hazard.

[0003] In order to prevent accidents and provide double protection, the furnace mouth water jacket is sprayed with refractory materials during weekly routine inspections to extend the service life of the furnace mouth water jacket. Manual application of protective materials may result in uneven application, especially for workers close to the furnace body. During construction, there are risks of heatstroke, burns, mechanical injuries, etc. Therefore, we propose a device suitable for spraying refractory materials, which can ensure that construction workers can spray refractory materials outside the high-temperature working area.

Then the worker adjusts the spraying direction of the fan-shaped nozzle 8 through the hose 7 so that the material is evenly sprayed on the position or equipment that needs protection.
