Definitions

  • the only entry-side dispensing of coolant on the work rolls and / or on the rolling stock prevents larger amounts of coolant are carried out the outlet side of the reversing mill, which is precisely at higher rolling speeds of the rolling stock due to the Mass inertia of the coolant can occur.
  • the only spraying of the work rolls and/or the rolling stock on the outlet side with the mixture of the lubricant and the carrier gas takes into account that with spraying on the inlet side and simultaneous dispensing of coolant on the inlet side on the work rolls and/or on the rolling stock, the coolant can prevent the mixture from the lubricant and the carrier gas reaches the work rolls and/or the rolling stock.
  • At least one spray beam and at least one cooling beam are arranged on at least one side of the reversing rolling stand.
