Forging technology metal alloy semi-solid billet cooling and heat preservation new technology Luo Zhonghua, Zhang Wenliang 2 (1. Department of Mechanical and Electrical Engineering, Shanghai Jianqiao University, Shanghai 2013192. Department of Plastic Forming Engineering, Shanghai Jiaotong University, Shanghai 200030), time is also conducive to billet heating temperature The field is more even. The ZL101 semi-solid alloy billet was cooled and kept at constant temperature and heat-insulated. The binary eutectic melting temperature of ZL101 alloy was 577 ° C. The thermal conductivity of the solid phase of the ZL101 alloy was measured / the thermal conductivity of the liquid phase (Wm-1K-1) Coefficient / (Wm-1K-1) latent heat of fusion / (convective heat transfer coefficient (free) / convective heat transfer coefficient (contact) / average density / (kgm-3) solidus temperature / C liquidus temperature / C 520 Conversion module + computer serial port + diameter 3mm inch is !60mmX70mm, drill in the center of the end face! 3.5mmX35mm hole; in order to facilitate the placement of thermocouple, drill the hole in the middle of the cylinder surface! 35mmX2mm hole.
The heating temperature of the test piece is 560C. (a) is the cooling and heat preservation heating process, heating to 565C in 140min, then using the cooling and heat preservation; (b) being the constant temperature heat preservation heating process, heating to 560C in 150min, then , using constant temperature insulation.
