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 4D20 carbon steel elbow, the movement is heated, expanding and forming the bending process. Picks elbow tube diameter deformation characteristics are determined based on the volume of the plastic deformation around the same law metal material used is smaller than the diameter of the tube elbow diameter mandrel controlled by deformation of the blank 20 carbon steel elbow DN150, the inner arc of the metal flow is compressed, the compensation due to the other parts of the expanding 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 features 20 carbon steel elbow DN100, and thus become carbon steel, alloy steel elbow primary forming method, and also used in certain These kinds of stainless steel elbows 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.
