Fault Diagnosis for Rebar Rolling Mill
The rebar rolling mill is one of the key production lines for producing steel bars for construction. This process of hot rolling steel involves passing the billet from the heating furnace to the rebar rolling mill and then through the finishing mill bed. During the process, the rollers in the roll stand of the rolling mill shape the billet and reduce its cross-sectional area. In order to ensure smooth operation and high quality product, it is particularly important to diagnose the fault of the rolling mill in time and identify the causes.
I. Common Faults of Rebar Rolling Mill
1. Rolling Mill Fault: Rolling mill fault includes fault of running startup and shutdown, fault of acceleration and deceleration, blockage of roller stand, vibration of rolling mill, etc.
2. Bearing Bearing Fault: Bearing fault includes bearing rust, bearing lubricating effect, loosening of bearing cap, bearing temperature rise, etc.
3. Rolling Mill Accessories Faults: Rolling mill accessories include transmission components and accessories, detection components, electric control components, etc.
4. Presence of Material Flaws in the Finished Product: Under normal circumstances, under proper operating conditions, the finished product should have uniform hardness and size, and these parameters should be consistent with the requirements specified by the customer; if there are too many materials that do not meet the requirements, they need to be found out as soon as possible.
II. Fault Identification Method of Rebar Rolling Mill
1. When the fault of the rolling mill is generally not very obvious, first of all, the fault should be identified through various methods; the operator should first check whether the operation of the machine is normal, including the operation of the rollers, vibration, noise and other parameters; if there is irregular abnormality that can be described, it can be used as an initial investigation clue.
2. Then, the operator should further check the parts of the machine, including the bearing part, the transmission part, the electric control part, etc., in order to identify whether there is an obvious fault in the parts. If there is, it can be used as a fault clue for further research.
3. At the same, the operator should also check all parts of the rolling mill for dust accumulation and abnormal assembly, and inspect all related parts for wear and tear.
4. Finally, the operator should also check the product itself to see if there are any flaws or problems, and use this result to identify the cause of the fault and take the necessary measures.
III. Conclusion
The fault diagnosis of the rebar rolling mill is very important for designing a safe and reliable production line and improving product quality. Through the above analysis, it can be seen that the field diagnosis of the rebar rolling mill needs to make full use of various clues, and the operator needs to check all parts of the machine to find out the cause of the fault. After finding out the cause of the fault, the operator or other personnel can take the necessary measures in time to solve the fault.
