摘要： A manufacturing method for glass beads for XRF according to an embodiment of the present invention comprises: a step of charging a crucible with a Fe-P ferro alloy, a fusing agent, and an oxidizing agent; a first heating step of oxidizing the charged Fe-P ferro alloy by heating the crucible; a second heating step of melting the oxidized Fe-P by reheating the crucible; a step of conveying the melt into a mold; and a step of forming glass beads by cooling the mold which receives the melt. In the charging step, the fusing agent is firstly put into the crucible, a mixture of the Fe-P ferro alloy and the oxidizing agent is put into the top center of the charged fusing agent in order to avoid being in contact with the crucible, and then the fusing agent is put into the crucible again in order to cover the whole charged materials. In the charging step, the weight of the charged fusing agent is 30 to 40 times of the weight of the Fe-P ferro alloy, and the weight of the charged oxidizing agent is 4 to 6 times of the weight of the Fe-P ferro alloy.
摘要翻译：根据本发明的实施方案的用于XRF的玻璃珠的制造方法包括：用Fe-P铁合金，定影剂和氧化剂对坩埚进行充电的步骤; 通过加热坩埚来对带电Fe-P铁合金进行氧化的第一加热步骤; 第二加热步骤，通过重新加热所述坩埚来熔化所述氧化的Fe-P; 将熔体输送到模具中的步骤; 以及通过冷却接收熔体的模具来形成玻璃珠的步骤。在充电步骤中，首先将定影剂放入坩埚中，将Fe-P铁合金和氧化剂的混合物放入充电的熔融剂的顶部中心以避免与坩埚接触，然后将定影剂再次放入坩埚中以覆盖整个带电材料。在充电步骤中，充电熔合剂的重量为Fe-P铁合金的重量的30-40倍，并且带电氧化剂的重量为Fe-P铁的重量的4至6倍合金。
