摘　　要：借助高温物性测试仪、黏度仪、原位热分析仪及傅里叶变换红外光谱仪等,研究了B_(2)O_(3)含量对无氟CaO-Al_(2)O_(3)-BaO基保护渣熔化温度、黏度和结晶性能的影响。结果表明,当B_(2)O_(3)含量为7%时,无氟CaO-Al_(2)O_(3)-BaO基保护渣熔化温度、黏度和结晶性能最佳。The effects of B_(2)O_(3)content on the melting temperature,viscosity and crystallization properties of fluorine-free CaO-Al_(2)O_(3)-BaO-based mold fluxes were studied by using high-temperature physical function determinator,viscometer,in-situ thermal analyzer and Fourier transform infrared spectrometer.The results show that when the content of B_(2)O_(3)is 7%,the fluorine-free CaO-Al_(2)O_(3)-BaO-based mold fluxes have the optimal melting temperature,viscosity and crystallization properties.
