Induction & Electric Arc Furnace Splash
Molten metal splash can occur any time molten
metal is in an induction melting or holding furnace. Te causes include the introduction of foreign material or mois- ture into the bath and refractory lining failure. Te metalcast- ing facility should designate a hazard zone around induction melting furnaces and mark it with color coding or post signs warning of the hazard. Te hazard zone extends from the edge of the induction melting furnace to a distance of 20 ft., or five times the crucible inner diameter (whichever is greater), radially from the center of the furnace. Refer to ASTM 2349 Paragraph 9.2.10 for induction furnace guidelines and ASTM 2349 paragraph 9.3.18 for electric arc furnace guidelines.

感应炉和电弧感应炉飞溅
金属液飞溅会发生在熔融金属处于感应炉 或者保温炉的任何时刻。其原因包括不同 材料或者湿气进入金属液和耐火材料炉衬缺陷。金属 铸造厂应该在感应炉周围划出一个危险区域，并用颜 色标记或者用警告标语提示危险。危险区域从感应炉 中心向四周辐射，从感应炉边缘延伸20英尺，或者5 倍的坩埚内径（选取更大的一个）。参考美国材料实 验协会2349标准9.2.10章节关于感应炉的准则和美国 材料实验协会2349标准9.3.18章节关于电弧感应炉的 准则。
建筑物保养
确保熔炉、浇注区域和高温金属运输通道周围的 建筑物屋顶、窗户和天窗状态良好。从屋顶渗漏 下来的少量液体（水）会引起麻烦。在天气恶劣时，要特别 关注水、雪和冰。
丁烷打火机
丁烷打火机在金属熔炼上是禁止使用的。如 果掉落进入金属液中，在打火机中的液体会
Water is an integral part of the centrifugal casting mold cooling process, and surrounding areas should be kept dry.
