最近,哈尔滨工业大学研制成功球形容器制造新工艺。专家们认为,该工艺构思新颖,属国际首创。据悉,这项新工艺既不需大型压力机,也不需高精度的模具,只需把钢板切割成正六边形,通过特殊的焊接工艺拼装,再充液加压即可做成不同大小的圆形容器。哈工 Recently, Harbin Institute of Technology successfully developed a new manufacturing process of spherical containers. Experts believe that the concept of innovative technology, is an international initiative. It is reported that this new process does not require large presses, do not need high-precision molds, just cut into regular hexagonal steel, assembled by a special welding process, and then replenishment pressure can be made into different sizes Round container.
