The main tendency of ferrous metallurgy development is improvement of automotive sheet quality and production of the new steel grades which meet the requirements of the international standards. The studied subject is continuous cold strip mill 2500. Analysis of the defects for emulsion spots and spotted carburization showed that their distribution is irregular across the strip width. In the world practice, there are various ways to remove the lubricating and cooling liquid from the rolled strip during the production of automotive sheet by a cold rolling mill. Special modern systems are developed by both foreign and domestic firms are used to remove cooling lubricant from the strip. But significant disadvantage of such solutions is high cost. So, the rational solution of this problem is the development of an innovative technology for removing the cutting compound based on the principle of blowing with minimum amount of compressed air. The article describes an innovative system for cleaning the strip from the residues of the lubricating-cooling liquid in the production of an automotive sheet on the four-stand cold rolling mill 2500 and calculation of parameters. The implementation of improved automotive sheet production technology will reduce the compressed airflow more than 2.5 times, compared with the current system and significantly to expand the range of products. |
