2026年10月19日，通过客户和当地合作伙伴的努力，韩国铸造企业 Woojeon Metal 完成 RFD45 砂冷却器升级改造并顺利投产。改造前，该砂冷却器入口旧砂温度高达 176.4℃，高温旧砂直接进入混砂工序，极易造成砂温失控，诱发气孔、夹砂等铸件缺陷，长期困扰生产。

本次改造重点优化冷却换热结构、流化布风系统以及自动加水温控模块。改造投运后实测，旧砂出口温度稳定降至 40.0℃，降温幅度十分突出。稳定可控的砂温有效提升型砂性能一致性，显著降低铸件缺陷风险，同时减少设备能耗与日常维护工作量。

现场实测数据充分验证改造方案达到预期设计目标，该项目为同类型铸造砂冷却设备升级提供了成熟的工程参考案例。



On October 19, 2026, thanks to the efforts of the customer and local partners, Woojeon Metal, a foundry in South Korea, has finished the upgrade of its RFD45 sand cooler and put it into operation. Before retrofit, the temperature of reclaimed sand at the cooler inlet was up to 176.4℃. Hot sand fed directly into the muller would cause unstable sand temperature and easily lead to casting defects such as blowholes and scabs, troubling production for a long time.

This retrofit optimized the heat exchange structure, fluidization air distribution system and automatic water adding & temperature control module. Field measurement after commissioning shows the outlet sand temperature is stably reduced to 40.0℃ with excellent cooling performance. Stable sand temperature improves consistency of molding sand properties, greatly cuts casting defect risks, and lowers energy consumption and routine maintenance work.
