During the production process of the steel rolling mill, once an unexpected accident occurs or the rolling mill shuts down for normal maintenance, the rolling mill should pay attention to some matters after shutting down.

  1. After the rolling mill is shut down due to an unexpected accident, the steel feeding and feeding should be stopped, and the online rolling pieces should be cut and taken out by gas cutting to avoid stress on the rolls and causing damage.
  2. If the rolling mill needs to be shut down for a long time, the lubrication system needs to be opened to keep the main bearings lubricated, and then closed to prevent dust from entering the bearings and affecting the restart of the machine.
  3. Cut off the power supply of the rolling mill and auxiliary equipment.
  4. Drain the water in the cooling pipe to prevent the cooling water pipe from freezing and cracking when the weather is cold.
  5. Protect the lubrication system, motor, air separator and slow drive from dust. But don’t seal it too tightly to avoid moisture accumulation. Use a small heater or protective light bulb to prevent moisture accumulation.
  6. Place bags of desiccant in all control and electrical panels to prevent moisture accumulation and securely seal the control panels.
    These precautions are something that steel rolling production enterprises need to pay special attention to. Only by doing a good job of maintenance work when the rolling mill is shut down can it be more convenient and faster to invest in re-production, and it can also improve the rolling efficiency and extend the service life of the rolling mill.
Precautions when the rolling mill is shut down for any reason during the production process

Product advantage

The world No. 1 in crude steel production steel plant, over 70% of the HSS for bar and wire are from us.

LMM high-speed steel rolls have higher steel passing per groove (times) due to their good wear resistance, which saves roll changing time, improves rolling mill operation rate, reduces roll consumption, and improve the overall efficiency of the factory.
Generally, the amount of steel passing in a single groove (times) is 3 to 5 times that of cast iron rolls.
