How to Improve the Purity of 316L Stainless Steel Welded Pipe
316L stainless steel pipe if it contains impurities, not only its surface quality, the impact of its performance is immeasurable. And if want to reduce the 316L stainless steel pipe impurities, improve its purity, it is necessary to start from the production process. The following is to improve the purity of 316L stainless steel pipe method. 1, To avoid impurities into the steel. a. Manufacturers in the procurement of raw materials (scrap, ferroalloy, etc.), slagging information (lime, fluorite, etc.), deoxidized data quality and baking, boring; b. Stainless steel pipe manufacturers of steel-making workshop lining, ladle and pouring system with the quality of refractory materials and baking; c. Progressive steelmaking gas (argon, oxygen, nitrogen, etc.) purity (can not have water, etc.); d. Avoid secondary oxidation of molten steel during tapping and pouring. 2, Removed from the steel. Manufacturers in the production of the method is selected AOD, VOD and oth...
