Rapid Switching Between Multiple Formulas: Graphitization Furnaces No L"&"onger a Problem
Last year, I visited a research institute. Their heat treatment lab had an old furnace, and the experienced operator complained to me that the biggest pain point wasn't the inability to reach the required temperature, but rather t"&"he hassle of changing materials. They, as R&D staff, frequently had to test different materials each day, switching formulas and process parameters. Each time they changed products, they had to reset a whole string of temperature parameters, which was not"&" only chaotic but also prone to errors, wasting an entire batch of material.
I told him that this problem has been completely solved in the new generation of graphitization furnaces.
Our control system features built-in **multi-recipe manageme"&"nt functionality**, making production changeovers no longer a time-consuming and laborious process, but a matter of seconds. **Recipe Storage and Version Management** Each set of process parameters—heating curve, holding time, atmosphere switching point"&", cooling rate—can be saved as an independent **process recipe** in the system. The system can store hundreds of recipes, each with a unique name and number for easy retrieval. More importantly, recipes support **version management**; each modification au"&"tomatically saves the historical version, allowing for easy reverting to previous settings, ensuring that trial-and-error records during the R&D process are not lost. Process recipes can be imported via USB drive or manually entered by administrators. Inp"&"ut can be done by minute, hour, or even minute; our program allows for switching between these methods and can even be remotely updated or automatically entered via barcode scanning. One-Click Recall When switching to a specific product, the operator "&"finds the corresponding recipe name or code on the touchscreen, clicks ""Recall,"" and the system automatically loads and displays all recipe parameters and information, including a JJAD curve preview. After confirmation, it can be started with a single c"&"lick. The entire process takes only a few seconds, requiring no manual input of any numbers or item-by-item verification. Our temperature controller automatically compares the recipe data after it is written into the system, ensuring accuracy. This functi"&"on is invaluable in scenarios involving frequent switching, such as ""burning product A today and product B tomorrow."" Permission Management To prevent accidental operation, the system supports multi-user permission management. Process engineers can "&"create and edit recipes, while regular operators can only use authorized recipes and execute production. Management can view all operation records. This ensures the confidentiality of process parameters and prevents unauthorized modifications. **Actual "&"Results:** After implementing this system, the research institute's changeover time was reduced from 1-2 hours (manual reset, verification, minute-hour calculations) to just a few minutes. R&D personnel can focus more on process optimization rather than s"&"truggling with equipment.")
