Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for adjusting carbon potential and dew point in heat treatment processes are cumbersome, relying on obscure and indirect methods that are prone to user error, requiring historical data and manual trial-and-error adjustments.
Innovation Solution
A system and method that uses a process controller with a user-friendly interface to automatically calculate and adjust compensation factors, such as the CO factor or H2 factor, based on direct input of actual carbon potential or dew point measurements, eliminating the need for manual intervention and reducing the likelihood of errors.

Engineering Contradiction Analysis
1Reliability
If manual trial-and-error adjustment of CO factor is used, then carbon potential control is achieved, but the process is time-consuming and prone to user error
Solution Approach 1:
The system implements automatic feedback control by continuously monitoring actual carbon potential measurements and comparing them with target values. The controller automatically adjusts the CO factor based on the difference between measured and desired carbon potential, eliminating manual trial-and-error and reducing adjustment time while improving reliability through consistent automated control.
Solution Approach 2:
The controller performs self-adjustment of the CO factor using built-in algorithms that process carbon potential measurements and automatically modify control parameters. This self-service capability eliminates the need for operator intervention in the adjustment process, reducing both time loss and human error while maintaining accurate carbon potential control.
2Reliability
If historical data and manual intervention are required for adjustment, then carbon potential can be controlled, but the complexity of the operation increases
Solution Approach 1:
The controller automatically retrieves and processes historical data, performs calculations, and adjusts the CO factor without requiring manual intervention. The system serves itself by autonomously completing the entire adjustment process from data retrieval to parameter modification, thereby maintaining reliable carbon potential control while dramatically simplifying operation for the user.
Solution Approach 2:
The manual mechanical process of retrieving historical data, calculating adjustments, and physically adjusting parameters is replaced by an automated electronic control system. The controller uses software algorithms to perform all adjustment operations, substituting manual mechanical operations with automated electronic control, thus improving ease of operation while maintaining control reliability.
