- 摘要:
- 较大口径闸阀铸件水玻璃精密铸造及砂型铸造存在各种质量问题。随着时代的发展,铸钢阀门市场对产品质量要求的进一步提高、市场竞争的加剧,对产品的质量和生产周期要求越来越严格。采用计算机模拟软件对较大口径阀体铸件进行了工艺模拟,并采用硅溶胶+水玻璃复合精密铸造进行了试制。结果表明,成功开发了16″-150LB阀体铸件,产品质量达到要求,保证了交货周期。
There are various quality problems in sodium silicate precision casting and sand casting of large caliber gate valve castings.With the development of the Times,the cast steel valve market on the product quality requirements to further improving,the intensification of market competition,the quality of products and production cycle requirements are more and more strict.The process of large caliber valve body casting was simulated by computer simulation software,and precision casting by silica sol+sodium silicate composite was carried out.The results show that 16″-150LB valve body casting is successfully developed,the product quality meets the requirements,and the delivery cycle is guaranteed.
