Oxygen blowing pipes are used for steelmaking oxygen blowing pipes. Generally, small-diameter welded steel tubes are used, and the specifications range from 3/8 inch to 2 inch.
The use of oxygen blowing tube
(1) Oxygen or other gases are transported in the electric arc furnace steelmaking, and the steel is melted and refined in the electric arc furnace.
(2) Inject other powdered additives to adjust steel grades or refine special steels.
(3) Remove the slag in the oxygen converter.
(4) Other uses, such as in strong heat resistance, oxidation resistance, vulcanization resistance and corrosion resistance.
The characteristics of the oxygen blowing tube
1. Low consumption. The high temperature resistant coating together forms a strong heat resistance and oxidation resistance, which can achieve the lowest consumption of oxygen lance and reduce the cost.
2. High quality: All production links from the screening of raw materials to the production of finished products are under strict quality control management.
3. Low price: The production line formed by more advanced production equipment has realized the high quality and low price of the product.
The length of the oxygen blowing tube
The oxygen blowing pipe is generally 6 meters long, and the length of the oxygen blowing pipe 8*1 can be 9.3 meters.
Cleaning and preheating of oxygen lance
Oxygen lances are widely used in the fields of construction and industry, and the cleaning and preheating of oxygen lances are as follows:
Before spraying (throwing) treatment, use cleaning method to remove grease and scale on the surface of the oxygen blowing tube, and use a heating furnace to preheat the tube body to 40-60 °C to keep the surface of the oxygen blowing tube in a dry state. During spraying (throwing) treatment, since the surface of the oxygen blowing tube does not contain dirt such as grease, the effect of rust removal can be enhanced. The dry surface of the oxygen blowing pipe is also conducive to the separation of steel shot, steel grit, rust and scale, making the surface of the oxygen blowing pipe cleaner after derusting.
Process flow of oxygen blowing tube
Tube blank--inspection--peeling--inspection--heating--perforation--pickling--mushroom repairing--lubricating and air-drying--welding head--cold drawing--solution treatment--pickling passivation-- test
Tips: Welded pipe is a steel pipe made of steel plate or steel strip after crimping and welding. Welded steel pipe has simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but its general strength is lower than that of seamless pipe.
