| Abstract: | The bubbles on the surface have bad effect on the appearance quality and further resistance of rusting of hot rolled ribbed bar. It is proved by difference cooling tests that the finish rolling temperature and the temperature of terminated cooling are the importance factors. The solutions to above the problem are setting an accelerated controlled cooling device behind the finished rolling mill and adjusting proper cooling parameters. It is a commercial, practical process. |
