摘要
以硅酸盐耐火材料作浇注模型,分别在磁场、电场、电磁场条件下,采用底注式浇注方式浇注ZL114合金(浇注温度为710℃),研究上述场及场强对合金凝固组织的影响。结果表明,电场、磁场、电磁场对铸件凝固组织均有影响,其中大磁场、小电场可以达到细化组织的效果;在电磁场下,当磁场一定时,电场电流越小,其组织越均匀。
Using the silicate refractory as mould, ZL114（Si, 11.4%） alloy was poured at 710℃ on the conditions of magnetic field, electric field and electromagnetic field, respectively. The effects of each field and field intensity on alloy solidfication microstruture were studied. The results show that magnetic field, electric field and electromagnetic field have influences on solidfication microstruture. Under the condition of great magnetic field and small electric field, the fine microstructure can be obtained; in the same electromagnetic field, the smaller the current, the more uniform the microstructure.
