中温挤压可以使冷挤压变形困难的材料实现挤压成型,扩大了可挤压成型材料的范围。中温挤压可挤压成型大型零件,扩大了压力机的使用范围。同时,中温挤压不用软化退火处理;在润滑剂的保护下,毛坯没有氧化、脱碳等缺陷,优于热锻成形工艺,而且机械性能,尺寸精度,生产率效与冷挤压差不多。 Medium temperature extrusion can be cold extrusion deformation difficult materials to achieve extrusion, expanding the range of extrudable materials. Temperature extrusion can be extruded into large parts, expanding the use of the press range. At the same time, the temperature extrusion without softening annealing; under the protection of lubricants, the blank without oxidation, decarburization and other defects, better than hot forging process, and mechanical properties, dimensional accuracy, productivity and cold extrusion almost.
