Product Details of5A Molecular Sieve Adsorbent For Oxygen Concentrator in Steel Industry
5A Oxygen Molecular Sieve
5A Molecular Sieve for PSA/VPSA Oxygen Generation is a calcium-sodium molecular sieve with a crystal pore size of 5Å. Used for pressure swing adsorption (PSA/VPSA) to separate nitrogen and oxygen from the air. It has the characteristics of high nitrogen adsorption capacity, fast adsorption speed, strong adsorption selectivity, more complete vacuum or atmospheric pressure desorption, high strength and low attrition.

Oxygen blowing steelmaking
Oxygen blowing steelmaking: Oxygen blowing steelmaking has been widely adopted by various countries and has become an important way for the rapid development of the steel industry. Oxygen used in electric furnace steelmaking can accelerate the melting of furnace materials and the oxidation of impurities, which means that oxygen blowing in electric furnaces can both improve production capacity and quality. The oxygen consumption per ton of steel in electric furnaces varies according to the type of steelmaking, and the required oxygen concentration is 90% to 94% oxygen-enriched. The oxygen used in electric arc furnaces in small and medium-sized steel plants is obvious. The oxygen consumption is not large, generally around 1000 to 4000 Nm3 /h, and nitrogen is not required and gas is used intermittently. If deep cold air separation is used, the investment is high, the operating cost is high, and it is inconvenient to start and stop. The pressure swing adsorption oxygen production process meets the needs of electric furnace steelmaking, and the investment is effective quickly and the operation is convenient.
