Graphitization Furnace Project Acceptance: A Checklist Even Beginners C"&"an Understand
The graphitization furnace has arrived. How do you accept it? The following checklist will help you check each item to ensure the equipment is up to standard.
I. Visual Inspection
- ? Check for obvious scratches or peeling on the paint surface
- ? Check if the nameplate and markings are complete and clear
- ? Check if the "&"accompanying accessories, tools, and documents are complete
- ? Check if the furnace door opens and closes smoothly and if the seal is good
- ? Check if all valves operate f"&"lexibly
- ? Check if the pipeline connections are correct and secure
- ? Check if the mechanical locking device is reliable
- ? Insulation resistance test, supplier"&" report required (≥1MΩ) ? Grounding resistance test, supplier report required (≤4Ω) ? All terminals are securely fastened ? Cable markings inside the electrical cabinet are clear **IV. Functional Testing** **? Vacuum Test:** Evacuate to ultimate vac"&"uum, pressure rise rate ≤ standard value **? Temperature Field Test:** Ceramic temperature sensing rings are used, temperature difference ≤ standard value **? Heating Test:** Reach operating temperature, temperature control accuracy ≤ ±1℃ **? Safety In"&"terlock Test:** Simulates a fault, interlock action is correct **?** **Alarm Function Test:** All alarm points triggered normally. **V. Product Verification (Most Critical)** **Firing a batch using the customer's actual materials to test if the product"&" performance meets the standards.** This is the final acceptance standard—if all previous tests are passed, but the product is unqualified, the equipment cannot be considered accepted. **Principle:** Item-by-item acceptance, data-driven approach, no sign"&"atures for unqualified items. Every signature on the acceptance report signifies your approval of the equipment. A responsible and thorough acceptance process protects the company's interests.")
