Different users can have different rights in the system such as

‘read only’ or ‘administrator’ to protect modules from unauthorized

access.

3.1.1 Products

The products module is the central module to operate the stretch

reducing block. The user can define different products, which can

be related to different rolling cycles (figure 3). These cycles are

used to arrange products in groups.

Grouping can be achieved in relation to the rolling plan in the mill or

with reference to grade, size, and wall thickness. Other criteria can

be easily selected by the customer.

3.1.2 Parameters for technological

functions

Together with the calculation of the speed data for

the motors, the parameters for the technological

functions are determined. Each technological

function, described in the chapter ‘TecBox’, has

a set of parameters in order to adjust the system

best.

Only the most necessary set of parameters

is presented to the customer for manual

adjustments. All other parameters are determined

by the program in relation to the pass design,

size and wall thickness.

For example, factors for the HEC depend on the

number of rolling stands used for the specific

product.

3.1.3 Roll set management

Conventional stretch reducing mills with group drives and non-

adjustable stands have many stands whereas the new Kocks SRB

has roll sets for the whole production schedule, but needs only few

stands. After rolling, the roll sets are dismounted from the stands

and new roll sets for a different product are mounted.

Therefore, a very important function is roll management, which

means machining, re-machining, and modification to a different

position in the pass schedule. For the remote control system, the

knowledge of the installed roll system is also necessary to determine

the adjustment values.

3.1.3.1 Roll history

All steps of the lifecycle of the roll sets in the SRB can be managed

with the Tumicon mill manager.

Roll definition

In the roll definition module, suitable passes are

defined for all products with regard to the pass

design; Tumicon automatically performs this

activity. Normally, the list of passes is created

by Kocks. However, the user can define their

own passes, eg for a different free-size range or

different finished sizes.

Ordering of roll sets

By using the order function in the roll definition

module, a new roll set is inserted in the roll

inventory module. Tumicon allows manual

designation of the individual roll sets, but

the use of automatic numbering (standard

description) with a unique identifier is

recommended. It is possible to create a list of

rolls to be ordered to obtain the new roll sets

from a supplier. All necessary geometry data

are available.
