The invention relates to a manufacturing device and processing method for super-thick-walled large-diameter corrugated pipes. The device includes a mold body, a pouring component and a control component. The mold body contains a rolling device, and the rolling device can pass through the control component. Control the roll forming of castings in cooling after pouring to realize the manufacture of corrugated tubes with arbitrary waveforms. The invention also provides a manufacturing method for super-thick-walled and large-diameter built-in corrugated tubes, which uses molten metal for casting to avoid pouring Process splashing and gas entrapment, due to roll forming during the casting cooling process reduces the generation of deformation resistance, effectively reducing energy consumption, and due to the existence of solid phase in the molten metal, thereby reducing the shrinkage of the casting , and through the subsequent rolling forming process, the precision of the casting and the compactness of the structure are guaranteed.
Description
technical field [0001] The invention relates to the field of manufacturing thick-walled pipes, in particular to a manufacturing device and a processing method for super-thick-walled large-diameter built-in corrugated pipes. Background technique [0002] In order to improve resource utilization, avoid resource waste, and reduce environmental pollution, large-diameter shell-and-tube heat exchange devices have been widely used in shipbuilding, petrochemical, aerospace, and national defense industries. The shell tubes of the shell-and-tube heat exchangers in the prior art mostly use ordinary smooth inner wall tubes. When the cold and hot flows flow through the tube side and the shell side respectively, due to the small effective heat exchange area of the heat exchanger, the fluid in the It is not easy to form turbulent flow in the heat exchange tube, which leads to the low heat exchange efficiency of this shell and tube heat exchanger, especially in petrochemical and other ent...
