由成都无缝钢管厂承担的四川省重点科研项目“离心浇铸不锈钢空心管坯工艺研究”已于1992年1月9日在四川省科委和冶金厅主持下通过省级技术鉴定。离心浇铸空心管坯是钢管管坯生产的一项新技术。采用离心浇铸技术生产的不锈钢空心管坯较电渣实心锭镗孔管坯的生产工艺简便、周期短。承担这一项目的研究单位经两年多的工业试验,掌握了离心浇铸不锈钢空心管坯的
The key scientific research project of Sichuan Province, which was undertaken by Chengdu Seamless Steel Tube Factory, was "passed the provincial technical appraisal under the auspices of Sichuan Science and Technology Commission and Metallurgical Department on January 9, 1992. Centrifugal casting hollow tube is a new technology for the production of steel tube blank. The centrifugal casting technology to produce stainless steel hollow shell than ESG solid ingot boring tube production process is simple, short cycle. Undertaken by the research unit of this project after more than two years of industrial testing, master the centrifugal casting stainless steel hollow shell
