比较系统地研究了生产渣浆泵过流件（护套、叶轮、前护板和后护板）用冷硬呋喃树脂砂的大量性能，即强度、硬化时间、可使用时间、起模时间、透气性及表面稳定性等，并对影响这些性能的诸因素进行了分析研究，在此基础上进行了生产性试验，取得了良好的效果。
A large number of properties of chilled furan resin sand used in the production of over-current components (sheath, impeller, front guard and rear guard) of slurry pump are systematically studied, that is, strength, hardening time, serviceable time, Breathability and surface stability, and other factors that affect these properties were analyzed and studied on the basis of the production test, and achieved good results.
