摘要 以CaO-SiO2-TiO2渣系为基础配制了含钛无氟结晶器保护渣,为建立和优化配置规律,通过实验测定熔渣的粘度和熔点,研究了含钛无氟保护渣熔化特性与助熔剂、TiO2含量及二元碱度之间的关系。结果表明:B2O3和碱金属Na2O、Li2O均能有效降低粘度和熔点,其中以B2O3作用最为明显;TiO2含量为6%时,粘度和熔点均呈最小值。在4%~10%范围内,MgO可降低粘度,但会使熔点升高;含量〈3%时,MnO可降低粘度,含量超过5%则会同时使粘度和熔点增加。 Fluorine mostly comes from mold powders during the continuous casting process. Developing and using fluoride-free mold powders is of importance to the environmental protection. Fluoride fluxes were confected based on the CaO-SiO2-TiO2 slag system. In order to establish and optimize the confect rule of fluoride-free fluxes, the relationship between the melting properties of fluoride-free mold fluxes and fusing reagents, binary basicity and TiO2 content was investigated by measuring the viscosity and melting point of the melted slag. The experimental result indicates that the effective compositions in lowering the viscosity and melting point are 132O3, Na2O and Li2O, in which the effect of B2O3 is the most remarkable; When the content of titanium is 6 % in mass, both the viscosity and melting point show the minimum, If the content of MgO is 4%- 10%, it can reduce the viscosity but increase the melting point. MnO can help to reduce the viscosity when the content of MnO〈3%, but to increase the viscosity and melting point when the content of MnO〉5%.
