Rolling mill is the core equipment in modern iron and steel industry, and the reliability of its mill roll system (MRS) is the key to ensure the rolling process with high precision, high speed, continuity and stability. However, the MRS possesses some features such as high nonlinearity, time variability and strong coupling. The vertical vibration easily happens in its working process.
The vertical roller mill (VRM) is a kind of large equipment that widely used in cement materials industry. Since it always needs to work in the environment of heavy load, high temperature, high pressure and electromagnetic radiation interference, it breaks down easily. If the incipient faults information can't be detected in advance,
(Only in 1855 did the "American process" of making zinc oxide paint bring it to the U.S.) Later in the 19th century, paint manufacturers began employing roller mills, like those used to process grain, and English painters' guilds became trade unions.
