PLANENESS DETERMINING METHOD AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2005 - IPC

FIELD: method and apparatus for determining planeness degree of hot belt metallic article with use of measuring roller.

SUBSTANCE: measuring roller includes cylindrical outer surface having angular contact sector and free sector at hot rolling of ferrous and non-ferrous metals. Method is realized due to applying tension load to angular sector of measuring roller whose cylindrical surface has angular sector for engaging with metallic belt and free sector. Roller is positively cooled due to circulation of heat exchange liquid at least along part of free sector of outer surface of roller. Parameters providing efficiency of cooling such as opening degree of angular cooling sector, temperature and flow speed of circulating heat exchange liquid are set. At each revolution predetermined equilibrium temperature is achieved on outer surface of roller. Apparatus for performing the method includes measuring roller mounted with possibility of rotation around axis normal relative to lengthwise motion direction. Cylindrical surface of said roller has angular sector engaged with metallic belt applied onto it and subjected to tension load and free sector. Apparatus also includes unit positively cooling roller due to circulation of heat exchange liquid at least along part of free sector of roller and unit for controlling cooling condition in order to provided predetermined temperature of outer surface of roller.

EFFECT: possibility for controlling planeness of article along its whole length, possibly hot rolled belt, improved quality of product.
