由上海船厂铸锻分厂自行设计和安装的一台20吨台车式大型铸铁件喷丸清理室已于今年五月初投产试用,经三个多月的实际验证其性良好,符合设计要求。近年来,上海船厂在柴油机生产方面面临着机型更新和产品升级换代的新局面,新一代 RLB6s、RTA58、RTA38系列柴油机陆续投入试制。大型比的铸铁件使清砂问题成为铸造生产中十分突出的矛盾。我厂愿有一台清理用的小型喷丸清理室已远远跟不上生产的需要。为了适应造机生产的发展,铸锻分厂在总厂的大力支持下组织力量进行铸铁件大型喷丸清砂室的设计和 A 20-ton trolley-type large-scale cast-iron blasting chamber designed and installed by the Shanghai Shipyard Casting and Forging Plant has been put into trial operation in early May of this year. After more than three months of actual verification, it has good performance and meets the design requirements. In recent years, the Shanghai Shipyard is facing a new situation in the diesel engine production with model updating and product upgrading. The new generation of RLB6s, RTA58, and RTA38 series diesel engines have been gradually put into trial production. Large-scale cast iron parts make the problem of sand removal a very prominent contradiction in casting production. Our factory would like to have a small clean-up shot scavenging room that has been far behind the production needs. In order to adapt to the development of machine-building production, the casting and forging plant under the strong support of the General Plant organized the power to carry out the design of a large shot blasting chamber for cast iron.
