In the production and rolling process of the cogging mill, steel billets (the maximum diameter is 800 mm) frequently impact the vertical roller of the pushing bed, the support of the vertical roller device and the fixing bolt of the water tank of the pushing bed are broken after running for a period of time, and the lower half part of the vertical roller is inclined inwards. After the inclination exceeds the installation standard, the steel billet is contacted with the end lining plate, so that scratches appear on the outer surface of the steel billet, the quality of a finished product is affected, and production is stopped.
Therefore, the vertical roller is required to be frequently disassembled and a backing plate is welded behind the vertical roller support to adjust the position of the vertical roller, so that the maintenance cost is increased, and the production time is influenced. In addition, as the temperature of the steel billet reaches above 1000 ℃, lubricating grease in the vertical roller drops after high-temperature liquefaction after long-time rolling, the upper half bearing cannot be effectively lubricated, and is often blocked, even the retainer is broken, so that the vertical roller device has short service life.
