上海船厂原有设备生产呋喃树脂砂,产量低,铸件质量差,废品率高,旧砂不能再生利用,树脂加入量达2.4—2.5％,车间粉尘含量高。现引进国外部分关键设备,建成一条新工艺生产线,它由七个系统组成;制芯造型、落砂及旧砂回收、新砂及再生砂输送;除尘、有毒气体排放、动力装置及质量控制等。该生产线的主要特点:制芯、造型基本实现机械化;型砂、新砂采用密封管道输送,并 The original equipment of Shanghai Shipyard produces furan resin sand with low output, poor casting quality and high rejection rate. The old sand can not be reused, the amount of resin added is 2.4-2.5%, and the workshop dust content is high. Now the introduction of some key foreign equipment, the completion of a new technology production line, which consists of seven systems; core molding, sand and sand recovery, new sand and recycled sand transport; dust, toxic gas emissions, power plant and quality control. The main features of the production line: system core, the shape of the basic mechanization; sand, sand using sealed pipelines and
