【摘要】 本文采用微波加热技术来加热硬化水玻璃砂,通过调整水玻璃模数、改变水玻璃的加入量等条件, 分析水玻璃工艺参数对砂型试样抗拉强度的影响规律。试验结果表明,在微波加热功率539w、加热时间为20min条件下,水玻璃砂抗拉强度随着水玻璃的模数的增加而强度下降,随着水玻璃加入量的增多而强度值增大。更多还原

【Abstract】 By using microwave heating to cure water-glass sands , with modulus and content of water-glass varying, the influence of various parameters of water-glass sands on the tensile strength was investigated and analysed in this work. The results shows that tensile strength was decreased with the growth modulus but increased with the content of water-glass increasing, at 539w power heating for 20 min.更多还原
