水玻璃型壳在制壳流水线中的质量控制

Quality Control of Sodium Silicate Mould Casing in Casing Pipleline

根据水玻璃型壳在精密铸造中的质量标准和工艺原理 ,对水玻璃型壳在机械化制壳流水线中的质量控制进行了研究 ;从提高型壳质量出发 ,运用复合硬化制壳工艺 ,对水玻璃粘结剂、耐火粉料粒度、涂料搅拌与回性时间 ,硬化液的工艺要求等多种因素进行综合分析与控制。提出了运用综合控制的方法 ,减少生产中的随机因素 ,有效地控制产品质量的波动幅度 ,提高铸件质量 ,降低铸件废品率 。

Based on quality standard and technology of sodium silicate mould casing,research has been underway to the quality control in the mechanized casing pipleline.Moreover,utilizing composite hardening casing technology to sodium silicate sticking,the size of the refractory powder,paint agitates,and the technological requirements of hardening bath and so on are analysed together.Combination control means,may decrease the random factor in the manufacture ,effectively dominate the product quality.
