我国“七五”期间重点攻关项目一连铸PZ系列、HPZ系列喷咀,由西安重型机械研究所研究设计、江苏江都气动附件厂试制成功,于4月30日在扬州通过了国家机械电子工业部部级鉴定。这两种系列水汽雾化喷咀是连铸设备中的关键部件,适用于方坯、板坯连铸生产,对要求均匀缓冷的不绣钢等钢种尤为合适。 During the “Seventh Five-Year Plan” period in China, the PZ Series and HPZ Series nozzles were continuously researched and developed by the Xi’an Heavy Machinery Research Institute and the Jiangsu Jiangdu Pneumatic Accessories Factory. They were successfully tested and passed the National Machinery and Electronics Industry in Yangzhou on April 30th. Departmental level appraisal. These two series of water vapor atomizing nozzles are key components in the continuous casting equipment and are suitable for billet and slab continuous casting production. They are particularly suitable for stainless steels and other steels requiring uniform slow cooling.
