Our services in detail

1. Creation of process and tension diagrams:

Representation of the coil processing lines using symbols, with a focus on the strip and the process.
Physically and procedurally precise representation of the coil processing line functions.
Mapping of all strip tension-relevant drives including their design data, initially based on process and mechanical requirements.
Specification of the strip tensions and strip tension ranges (absolute and specific) for different line sections, with the possibility of calculating the strip tensions at any point of the line.
Adaptation of the process and tension diagram after the final design of the drives (motors) in order to be able to represent the strip tensions that can actually be achieved.

2. Carrying out analyzes of coil processing lines:

Determination of the process technological limits of the coil processing line.
Identification of product spectrums that can or can not be produced perfectly.
Identification of the areas in which perfect production is possible and analysis of weak points such as exceeding the coefficient of friction on S-rolls and pinch rolls as well as overloading motors.

3. Optimization of continuous and discontinuous coil processing lines:

Examples of continuous coil processing lines are annealing lines (CAL), pickling lines (CPL), painting lines (CCL) and coating lines (CGL).
Examples of discontinuous coil processing lines are stretch-bending-leveling lines, slitting lines, cut-to-length lines and rewinding lines.
Recommendations for optimizing coil processing lines based on analyzes of all (sub-)processes.
Consideration of mechanics, hydraulics, pneumatics, electrics and automation technology.

4. Targeted analyzes and optimization of coil changes:

Analysis of processes using iba-Analyzer.
Optimization of the sequences to reduce coil change times.

5. Analysis of the strip run and the strip flatness in coil processing lines:

Analysis of the strip run.
Derivation of measures with which the strip run and the strip flatness can be improved.

6. Development of optimal working points / set points / operating conditions for coil processing lines:

Under the given conditions (without carrying out modifications), the optimal working points / set points / operating conditions for the entire line are developed.

7. Analyzes of stretch bending leveling lines and levelers:

Identification of product spectrums that can or can not be produced perfectly.
Recommendations for necessary changes to the mechanics, electrics and/or automation technology when changing the product range.

8. Production and productivity calculations:

Analysis of the effects of changes in mechanics, hydraulics, pneumatics, electrical systems, automation technology and processes, etc. on the production quantity (t/a).
Economic considerations per investment, including cost-benefit analyzes and expected additional production with a defined product mix.
Examples: What are the effects of faster coil changes? What are the effects of higher process speeds? What is the effect of increasing the storage capacity in a continuous line?
Production calculations or productivity calculations can be carried out on all types of coil processing lines, e.g. pickling lines, galvanizing lines, continuous lines and discontinuous coil processing lines.

9. Advice on problems with coil processing lines:
