【Abstract】 The effects of the category and content of resin and activator, the gassing time of SO 2 on high-temperature strength, and the thermal stability of cold-setting SO 2 furan resin sand are investigated by means of a high- temperature tester and a non-linear calculation. Results show that the effects of categories and contents of resin and activator are remarkable, but the effect of gassing time is not obvious.更多还原
