Profile Measurement Specifications

1. Measurement Mode

Item

Scanning Pattern

Standard Specifications

←ライン流れ方向

Line flow direction

Full-width profile

scanning

In this mode the carriage is made to scan in a strip

width direction by a start profile measurement

command, thereby measuring the whole width profile.

The speed of the carriage is 30mm/s on both edges,

and 100mm/s at the center.

エッジ距離

Edge distance

Edge profile

scanning

In this mode the carriage is made to scan in a strip

width direction by a start profile measurement

command, thereby measuring the edge profile.

WS (or DS) edge distance is set beforehand from the

customer's computer.

Center

measurement

This mode measures the center of the strip

continuously in a longitudinal direction.

It is used as backup for AGC thickness gages (center

measurement).

2. Data Processing

The profile data processing shown below is carried out, and it is displayed on the operation-PC.

Note:

Line center

a. Edge distance settings i', i'', and j', j'' are the same.

b. i can be set from 5 to 50mm

(i can be set at 5 locations)

c. j can be set from 50 to 100mm

(edge drop standard)

3) Edge Drop Amount

1) Crown Value

Edge drop amount is calculated

Crown value, WS crown value, DS crown value are calculated

from the measurements of center plate thickness, WS side

specified measurement points and DS side specified

measurement points.

Crown values are calculated as follows:

a) Crown value: chi = hc- (hi' + hi'')/2

b) WS crown value: chi' = hc-hi'

from the measured width between

two points specified on the WS side

and DS side.

Calculations are made as follows.

a) WS edge drop amount:

eh' = hj' – hi'

b) DS edge drop amount:

eh'' = hj'' – hi''

c) DS crown value: chi' = hc-hi''

2) Wedge Value

Wedge value is calculated from the measured thickness at WS

side specified measurement points and DS side specified

measurement points.

The formula for calculation is shown below.

Whi = hi'' – hi'
