Roll Surface Inspection System

Chatter marks spirals shadows grit marks scratches indents etc.

Roll surface inspection system. Work roll inspection work rolls have a very important role in the rolling process as they need to have a special finish roughness that will be applied onto the surface of the strip. Special image evaluation software detects and displays roll surface defects such as chatter marks and feed lines commas or combinations of these and defines their location. With 20 sensors including 18 independent ultrasonic channels rollmate is the only system capable of detecting surface and internal defects in any orientation on any type of roll. Rollmate is the most advanced roll inspection system on the market.

All herkules grinders are equipped with the herkulesgroup hcc kpm kp10 control and on line on the fly roll measuring gauge. Depending on the particular task the web surface for surface inspection is detected using either incident light or transmitted light. Rollmate inspects rolls of any alloy forged and cast during or after the grinding process. After the inspection the operator immediately knows whether the roll is free of defects.

The roll surface inspection system registers and records the reflexion of a laser beam on the roll surface. Quality inspection overview rsis optical roll surface inspection system for roll grinders reduces down time of strip foil mills improves roll shop performance identifies and classifies finest surface finish patterns defects on ground rolls defect classes. The control is specialized for roll grinding in menue technics allowing on line monitoring of the process. The system also detects defects occuring only once.

Roll surface inspection system. A surface analysis system is normally installed after a process for quality control. Up until now it has been assumed that the fine structure has been finished after machining. In case a defect is found its size structure and position on the roll are indicated.

The key to a successful surface analysis is the scanning angle to the surface of the web and the arrangement of the light source.
