மோசடி மற்றும் நடிப்பு

வார்ப்புகளுடன் ஒப்பிடும்போது, ​​உலோகம் அதன் நுண் கட்டமைப்பு மற்றும் இயந்திர பண்புகளை மேம்படுத்த முடியும்மோசடி. After hot working deformation of the casting structure, the original coarse dendrites and columnar grains are transformed into fine-grained and uniform-sized equiaxed recrystallized structures due to the deformation and recrystallization of the metal, which causes the original segregation, The compaction and welding of loosening, porosity, slag inclusion, etc., the organization becomes tighter, improving the plasticity and mechanical properties of the metal. The mechanical properties of castings are lower than those of மோசடிs of the same material. In addition, the மோசடி process can ensure the continuity of the metal fiber structure, keep the fiber structure of the மோசடி consistent with the shape of the மோசடி, மற்றும் உலோக ஓட்டம் வரி முடிந்தது, இது பகுதிகளுக்கு நல்ல இயந்திர பண்புகள் மற்றும் நீண்ட சேவை வாழ்க்கை இருப்பதை உறுதிசெய்யும். துல்லியமான இறப்புமோசடி and cold extrusion The மோசடிs produced by hot extrusion and other processes are all unmatched by castings. The மோசடிs are metal objects that are pressed and shaped by plastic deformation to the required shape or suitable compression force. This power is typically achieved through the use of hammers or pressure. The casting process builds an exquisite granular structure and improves the physical properties of the metal. In the actual use of components, a correct design can make the particle flow in the direction of the main pressure. Castings are metal shaped objects obtained by various casting methods, that is, smelted liquid metal is poured into pre-prepared casting molds by pouring, injection, suction or other casting methods, and after cooling, the sand is dropped, cleaned and after Processing, etc., to obtain objects with a certain shape, size and performance.
