The energy-saving requirements of cold-drawn pipes and the society's call for restoring the natural environment are also getting higher and higher. In order to meet these requirements, new cold-drawn tubes will be developed, and new smelting processes and equipment will appear accordingly. With the continuous improvement of the mechanization and automation of casting production, more flexible production will be developed to expand the adaptability to different batches and multi-variety production. Priority should be given to new technologies for energy saving and raw materials, and new processes and new equipment that produce little or no pollution. Machines and equipment for special casting, as well as many transport and material handling equipment. The production of cast cold-drawn pipe has characteristics different from other processes, mainly including wide adaptability, many materials and equipment required, and large environmental pollution.
