High-speed rolling mill is similar to the conventional rolling mill. The ultimate goal is to obtain the required size of the rolled piece by rolling mill calendering. In rolling operation, in order to improve the operation efficiency of the high-speed rolling mill, it is necessary to take corresponding improvement measures.
The operation efficiency of high-speed rolling mill is mostly affected by unplanned parking, other equipment delays, roll and bearing replacement, and other process maintenance. Therefore, we need to improve the operation efficiency of the high-speed rolling mill in a planned way. The specific operations are as follows:
1. The material of rolls should be screened according to the requirements of the rolled parts to improve the fatigue strength and service life of the rolls.
2. Inspect the wear of roll and guide from time to time.
3. Inverse injection process of bearing lubricant from inside to outside to inside, so as to reduce the pollution of dust to bearing.
4. Using ultrasonic technology to inspect and analyze rolls.
5. The dry lubricating oil point has been modified. At present, the dry oil is added from the high-pressure zone. The amount of added oil increases from six cycles of raw materials to eleven cycles, and the thin oil lubrication is a 15-minute cycle. The cumulative effect of these changes can reduce the bearing temperature by several degrees Celsius.
With the upgrading of the steel rolling industry, new problems will arise, and we need to optimize and adjust the rolling process according to the actual situation at any time. This process requires us to explore step by step for a long time.
