Blow oxygen tubes are used for steelmaking oxygen blowing, generally made of small-diameter welded steel pipes, available in eight sizes ranging from 3/8 inch to 2 inches. They are manufactured from steel strips of grades 08, 10, 15, 20, or Q195-Q235. To prevent corrosion, some are treated with aluminum infiltration. The aluminum-infiltrated refractory coating blow oxygen tubes (PS series) consist of five layers: matrix layer, internal aluminum-infiltrated layer, external aluminum-infiltrated layer, internal coating, and external coating. Developed based on the S series, this product combines the actual needs of electric arc furnace steelmaking, featuring high refractoriness, low consumption, and ease of operation.
Oxygen lance pipes are widely used in construction and industrial fields. The cleaning and preheating of oxygen lance pipes are as follows: Before the spraying (abrasive) treatment, cleaning methods are employed to remove grease and dirt from the surface of the oxygen lance pipes. A furnace is used to preheat the pipe body to 40-60°C, maintaining a dry surface condition. During the spraying (abrasive) treatment, as the surface of the oxygen lance pipe is free of grease and other contaminants, it enhances the rust-removing effect. The dry surface of the oxygen lance pipe also facilitates the separation of steel shots, steel sand, rust, and oxide scale, resulting in a cleaner surface after rust removal.
