Shijiazhuang elbow and pipe prices by using the same sheet material into a stamping die stamping price of half a circular stone Shijiazhuang elbow, and then two half-price ring group Shijiazhuang elbow welding shape. Because different types of pipe welding standards, usually in groups to the point of semi-solid factory, construction site level of the pipe seam welding, therefore, Shijiazhuang, also known as the two halves welded elbow elbow. Smelting of stainless steel three-step stamping elbow that electric + blowing converter + VOD three steps. Characterized as a melting furnace equipment, Shijiazhuang, to provide the converter is responsible for elbow prices with Cr, Ni in the semi-finished steel, the main task of blowing converter oxygen blowing decarburization quickly to achieve maximum recovery of Cr purposes. VOD Vacuum Oxygen is responsible for further decarburization, degassing and composition of fine-tuning. Shijiazhuang elbow three steps relatively more suitable for the shortage of argon gas supply regions, the price of Shijiazhuang elbow and using a higher carbon content of hot metal as raw material, and the production of low C, low N steel stamping plant elbow with a larger proportion of professional . 88% of world stainless steel elbow with two-step stamping production, of which 76% is produced by AOD furnace. Therefore, prices are more suitable for large-scale Shijiazhuang elbow bend professional stainless steel stamping plant use |
