| Abstract: | Cracking is a kind of quality defect during medium plate production, winch happens most frequently with various complicated interactively influencing factors and is hard to be accurately and quantitatively described. Combined with defining cracking index and performing production trials at site, mathematical statistics is used to find out the quantitative relationship between cracking and influencing factors for medium plate, Based on an in-depth analysis, discussion on metallurgical process improvement, reheating and rolling practice optimization, cracking negative influence reduction is carried out. |
