分析了住友及新日铁生产彩管用框架薄钢板的工艺要点，以实例说明了实验过程，以图、表给出了实验结果。由得到的磁性及加工工艺性能表明，净化钢质，强化热轧及热处理工艺条件，是生产优质彩管用材的关键 The main points of the process of producing thin steel plate for CPT by Sumitomo and Nippon Steel are analyzed. The experimental process is illustrated with examples, and the experimental results are given in the form of charts and tables. From the magnetic and processing performance obtained shows that the purification of steel, hot-rolled and heat treatment process conditions, is the key to producing quality CPT wood
