Cangzhou Bohai Pipe Co., Ltd. specializing in the production of carbon steel elbow 20 elbow hot push forming process is the use of special elbow pushing machine, mandrel and the heating device, so set in the blank mold under the impetus pushing machine forward movement in the movement is heated, expanding and forming the bending process. Picks elbow tube diameter deformation characteristics are determined according to the law of constant volume before and after plastic deformation of the metal material, the use of tube diameter smaller than the diameter 20 carbon steel elbow elbow DN500, through the mandrel to control the deformation process of the blank 20 carbon steel elbow, so that the arc is compressed at a metal flow to other parts of the compensation due to the enlarged diameter and thinned, thereby obtaining a uniform wall thickness of the elbow. Elbow hot push forming process has a beautiful appearance, uniform thickness and continuous operation, suitable for mass production characteristics, and thus become carbon steel, alloy steel elbow primary forming method, and also used in certain types of stainless steel elbow The forming. Heating process of forming intermediate frequency or high frequency induction heating (heating coil may be a multi ring or lap), flame heating and reflection furnace heating, depending on what kind of heating the shaped product and energy requirements of decisions.
