Refractory Gunning Machine: The Ultimate Solution for High-Temperature Refractory Repair of Converters & Ladles
What sets the Refractory Gunning Machine apart is its exceptional ability to operate under the most challenging high-temperature conditions. Unlike traditional repair methods that often require shutting down equipment for extended periods or struggle to withstand residual heat, this advanced machine is engineered to tackle converter and ladle refractory repair directly at high temperatures. This means minimal downtime for your production line— a key advantage that translates to reduced losses and enhanced operational efficiency. Whether your converter is still retaining heat after a smelting cycle or the ladle is hot from recent molten metal handling, the Refractory Gunning Machine delivers reliable, high-quality repairs without compromising on safety or performance.
BOF Mouth: The mouth of the Basic Oxygen Furnace (BOF) is constantly exposed to splashing molten metal, high-temperature flue gases, and mechanical wear during charging and tapping. The gunning machine precisely sprays refractory material to rebuild the worn surface, restoring the mouth’s integrity and preventing leaks.
Flanks: The converter’s flanks endure intense thermal cycling and chemical erosion from molten slag. The machine’s high-pressure gunning system ensures uniform coverage and strong adhesion of refractory material, effectively resisting further wear and extending the flank’s service life.
Scrap Impact Zone: When scrap metal is charged into the converter, this zone suffers severe mechanical impact, often leading to cracks and material loss. The Refractory Gunning Machine applies a dense, impact-resistant refractory layer, reinforcing the area to withstand repeated scrap charging and minimizing downtime caused by unexpected damage.
Cone: The cone section of the converter is critical for guiding molten metal and slag, and it is prone to erosion due to constant contact with high-temperature fluids. The machine’s precise control allows for targeted repair of the cone, ensuring smooth flow of molten materials and preventing costly leaks.
Bottom: The converter bottom bears the weight of the entire molten bath and is susceptible to erosion from molten metal and chemical reactions. The Refractory Gunning Machine’s ability to apply a thick, durable refractory layer ensures the bottom’s structural stability, reducing the risk of catastrophic failure and extending the converter’s overall service life.
Taphole: The taphole is a high-wear area, as it is repeatedly opened and closed during tapping operations. The machine’s specialized gunning technology repairs and reinforces the taphole, ensuring proper sealing, consistent tapping flow, and reducing the frequency of taphole maintenance.
High Efficiency: With its automated operation and high gunning speed, the machine completes repairs in a fraction of the time required by traditional methods, minimizing production downtime and maximizing productivity.
Superior Quality: The machine ensures uniform distribution and strong adhesion of refractory material, resulting in a dense, durable repair layer that resists high temperatures, erosion, and impact.
Cost Savings: By extending the service life of converter and ladle refractory linings, reducing downtime, and lowering maintenance costs, the machine delivers significant long-term cost savings for your enterprise.
Safety: Equipped with advanced safety features, including heat-resistant components and remote control options, the machine ensures the safety of operators even in high-temperature working environments.
