Oxygen吹管 before the spraying process is cleaned to remove grease and sediment from its surface. The tube is then preheated in a furnace to maintain a temperature of 40-60°C, ensuring the surface remains dry. During the spraying process, the absence of grease and other contaminants on the surface of the Oxygen吹管 enhances rust removal. The dry surface of the Oxygen吹管 also facilitates the separation of steel shots, steel sand, rust, and scale, resulting in a cleaner surface after treatment. To prevent corrosion, some tubes undergo aluminum diffusion treatment. The Aluminum Diffusion Coating Oxygen吹管 (PS series) consists of five layers: matrix, inner aluminum diffusion layer, outer aluminum diffusion layer, inner coating, and outer coating. It is developed based on the S series and tailored to the current needs of electric arc furnace steelmaking, featuring high refractoriness, low consumption, and ease of operation. Additionally, the company maintains a year-round stock of Oxygen吹管 in sizes of 1/4", 3/8", 4 meters, and 6 meters, and can produce special specification coated Oxygen吹管 and special-shaped Oxygen吹管 to meet various factory requirements.
