Automation systems

Strip flatness automatic control is a knowledge-based control technology, without which today is unthinkable production of high-quality rolled products.

In the former USSR countries, in the cold rolling mills AFC of foreign design and manufacture were used, providing flatness measurement by contact method with, as a rule, sectioned measuring rollers (stress meters).

In the developed (firstly in CIS) AFC the effective innovative control algorithms were implemented, developed by MTM and ISI NASU staff, having years of experience in the theory and technology of production processes of rolled strips. As a strip flatness meter it is used a non-contact optoelectronic measuring device IP-4М of our partners - JSC "Inkomet".

Software components of AFC

The set of AFC includes:

Particularities of the AFC algorithms

In the controls algorithm of the selective rolls cooling, several important new features are realized that are not used in existing systems for automatic flatness control of the strips.
In particular, that:

Differences and competitive advantages

The main differences and competitive advantages of the developed system are as follows:

Firstly created AFC in the CIS, introduced in temper mill TM-1 NLMK has provided improved by 10-30% flatness of the finished strips.

MTM offers the comprehensive services that enhance the flatness of rolled wide strip lines in the hot and cold rolling.
