| Abstract: | In the production of thin gauge strip,it is faced with the problems of large temperature drop,difficult shape control,fast threading speed and poor rolling stability.Through analysis and the control of chemical composition,continuous casting process,temperature and shape control of SPA-H strip,the reasonable process parameters were determined,and 1.5 mm thickness of limit gauge of high-strength weathering SPA-H strip was developed.Combined with continuous casting speed and mold liquid level control,process temperature control and equipment precision control,stable rolling and mass supply of SPA-H strip with 1.5 mm thickness for handling containers was realized,which had high shape and dimensional accuracy,and stable mechanics performance to meet user requirements. |
