【摘要】 本研究选用B₂O₃作为含氟渣中CaF₂的替代物,在保证二者具有相近粘度和熔化性温度的基础上,选择了Na₂O含量为5%,CaF₂含量为15%的含氟结晶器保护渣与Na₂O含量为8%,B₂O₃含量为6%的无氟结晶器保护渣作为对比对象,研究了上述两种渣样的结晶温度、结晶能力及对结晶器控制传热的影响,为解决无氟保护渣准确控制传热问题提供基础信息和理论依据。更多还原

【Abstract】 B₂O₃ was selected as the substitute for CaF₂ in the study.The fluorine-containing powder in which Na₂O is 5% and CaF₂ is 15%and the free-fluoride powder in which Na₂O is 8%and B₂O₃ is 6%were determined as the research object. Then the crystallization temperature,crystallization capacity and the influence to controlling of heat transfer of above mentioned powder were studied.The purpose of the research is to provide the fundamental information and theoretical basis to controlling of heat transfer for the free-fluoride casting powder.更多还原
