Experience Unmatched Durability with Stellite Welding - The Ultimate Solution for Industrial Applications

PTA cladding blast furnace air nozzle Blast furnace air nozzles are often found in the metallurgical industry, and there are various types of air nozzles, such as large, medium and small, and the materials of the air nozzles are also different, which need to withstand extreme environments, such as the baking of high temperature of 1,500℃ and the impact of the iron and water flow. Blast furnace air outlet is made of high-purity copper. Copper has a high melting point, and conventional processes are unable to treat the surface of blast furnace air nozzles. Instead, Shanghai Dolmu's PTA Surfacing System melts the copper through compressed arc energy and surfaces the alloy powder on it. The use of PTA overlay welding for blast furnace air nozzles greatly increases the service life of blast furnace air nozzles and reduces the cost of replacement.
