How to improve the Rolling mill production line for steel plants to increase operating efficiency
In the operation of Rolling mill production line for steel plants, in order to improve the operating efficiency of the high-speed rolling mill, it is bound to take corresponding improvement measures. The operating efficiency of rolling mills is mostly affected by unplanned shutdowns, other equipment delays, roll and bearing replacement, and other process maintenance. Therefore, we need to plan for the improvement of high-speed rolling mill operating rates. The specific operations are as follows:
1. The material of the roll should be selected according to the requirements of the rolled piece to improve the fatigue strength and service life of the roll. Check the wear of rolls and guide guards from time to time.
2. Reverse the process of injecting bearing lubricating oil-from the original internal-external to external-internal, so as to reduce the contamination of the bearing by dust.
3. Rolling mill production line for steel plants uses ultrasonic technology to inspect and analyze rolls.
4. The dry lubricating oil point has been modified. At present, the dry oil is added from the high-pressure zone. The added amount is increased from six cycles of raw materials to eleven times. The thin oil lubrication is a cycle of 15 minutes. The cumulative effect of these changes can make The bearing temperature drops by a few degrees Celsius.
The effect and impact of high temperature, high pressure, and high speed gunpowder gas on the tube wall and the extrusion of the shell on the tube wall form a high tangential stress; the surface of the rolling mill production line for steel plants is subjected to alternating rapid heating (with The heating rate of ten ℃/s raises the temperature to over 710 ℃) and rapid cooling (ten ℃/s) make the steel structure produce repeated transformations of austenite and martensite, forming a very Large tissue stress and thermal gradient.
Rolling mill production line for steel plants can monitor the flow of oil into the bearing seat, and alarm in time when the flow of oil is blocked, effectively avoiding bearing damage; greatly reducing the consumption of spare parts, reducing the maintenance of the rolling mill, and increasing the output; and environmental protection .
