  • Control Of Metal Rolling (AREA)

Abstract

PURPOSE: To improve the quality of the product by exercising control over the degree of crowning and the shaping by providing a control mechanism for controlling the plate crowning combined with a conventional rolling device on the line of a hot roll finishing process.
CONSTITUTION: A light pressing stand 2 is placed at the down stream side of the final stand 1n of the hot finishing mill 1, and the light pressing stand 2 are doubled and quadruppled. The roll is variably crowned at the down stream of the light pressing stand 2, a hot levellers 3 are placed and at further down stream of them there are provided with pinch rollers 4. A steel band 7 is passed through the controlling system of crowning of plates that consists of these series of stands, and is wound up by a down coiler 6 via a cooling apparatus 5. Then the steel band 7 is controlled of its plate crowning by changing the amount of crowning of the light pressing stand 2 and pressing down of the roll selectively under the constant tension by the pinch rollers 4. The distortion caused by these is directly corrected by the hot leveller 3.
