保温冒口是七十年代发展起来的一种新技术,对减小铸件冒口尺寸,提高铸件工艺出品率,降低能耗,有非常显著的经济效益。为使这一新技术能在中船总公司系统铸造生产中更进一步得到推广应用,铸造专业网于1985年11月26日至28日在广州造船厂召开了“保温冒口技术交流会”。有22个铸造网成员单位、33名代表参加了会 Insulated riser is a new technology developed in the 1970s. It has very significant economic benefits for reducing the size of the riser, improving the production rate of castings, and reducing energy consumption. In order to further promote the application of this new technology in the foundry production of China Shipbuilding Corporation, Foundry Professional Network held the “Insulation Riser Technical Exchange Conference” at the Guangzhou Shipyard from November 26 to 28, 1985. 22 cast net member units and 33 representatives attended the meeting
