【摘要】：利用数值模拟和试验的方法,研究了铸造生产用型砂的热物性参数。结果表明:型砂与铸件间距离对浇注后型砂温度变化影响明显;型砂导热系数随温度升高呈现"V"形变化趋势,即当型砂温度低于400℃时,型砂导热系数下降,温度高于400℃后,导热系数增加;而型砂的比热则呈现随温度升高而升高的趋势,但温度低于600℃时,比热明显增加,当温度高于600℃时,比热增加缓慢。
[Abstract]:The thermal properties of molding sand for casting production were studied by numerical simulation and test. The results show that the distance between mold sand and castings has an obvious effect on the temperature change of mold sand after pouring. The thermal conductivity of molding sand changes with the increase of temperature, that is, when the temperature of molding sand is lower than 400 鈩，
