Which is characterized as a melting furnace equipment stamping elbow price favorably, is only responsible for providing the converter containing Cr, Ni semi-finished steel, LBE main task is blowing fast decarbonization, in order to achieve maximum recovery of Cr. Oxygen is responsible for further decarbonization VOD vacuum degassing and composition fine-tuning. Three-step method is more suitable for comparison of argon supply shortage preferred billion gold stamping elbow region and a higher carbon content of the molten iron as raw material, and the production of low C, low N stainless steel stamping elbow larger proportion of professional plant using. Currently 88% of world steel production stamping elbow two-step, 76% of which is produced by AOD furnace. Therefore it is more suitable for large stainless steel stamping elbow professional factory. Stamping elbow was first used in the production of seamless elbow elbow forming process stamping manufacturer, is currently in the production of common specifications elbow has been replaced by extrapolation or other hot forming process, but in some specifications the elbow due to a small number of production, the wall thickness is too thick or too thin. When the product is still in use with special requirements. Stamping elbow bends using the outer diameter equal to the tube, using the direct compression in a mold press forming.
