一九八四年二月由部计划司组织邀请有关厂所等三十余个单位的行家在大连油漆厂对我厂设计研制的ZFN-9型半自动缝焊机进行了技术鉴定。会议认为它的研制成功填补了我国制桶行业中马口铁缝焊设备的空白,改变了油漆桶制作工艺的落后面貌,其焊缝质量、生产效率等主要技术指标基本上达到了国外同类型产品的先进水平。其主要技术指标:①焊接马口铁厚度为0.28～0.32毫米。②焊接桶体直径为φ100～
In February 1984, the Ministry of Planning invited the experts of more than 30 units including the factory to conduct technical appraisal on the ZFN-9 semi-automatic seam welder designed and developed by our factory at Dalian Paint Factory. The meeting believed that its successful development has filled the blank of the tinplate seam welding equipment in China’s barrel making industry, changed the backward appearance of the paint bucket manufacturing process, and its main technical indicators such as weld quality and production efficiency have basically reached the same type of foreign products. Advanced level. Its main technical indicators: 1 welding tinplate thickness of 0.28 ~ 0.32 mm. 2 Welding barrel diameter is φ100～
