Housing less Mill Stands
Housingless mill stands are a critical component in the rolling mill industry, particularly in the production of long steel products such as bars, rods, and structural sections. These mill stands play a crucial role in ensuring the efficient and precise rolling of metal materials.
Housingless mill stands, also known as open-type mill stands, are a type of rolling mill stand used in the rolling of long steel products. Unlike traditional mill stands, housingless mill stands do not have a housing or frame surrounding the roll stands. Instead, they consist of individual roll units, each mounted on its own set of bearings and supports.
How Housing less Mill Stands Works
Roll Units: Housingless mill stands consist of multiple roll units, each containing a pair of rolls. These rolls are responsible for shaping and reducing the cross-section of the metal material as it passes through.
Pass Schedule: A pass schedule is a predetermined sequence of rolling passes that the metal material undergoes to achieve the desired shape and dimensions. Each pass in the schedule corresponds to a specific roll unit.
Rolling Process: The metal material is fed into the first roll unit, where it undergoes the first rolling pass. After each pass, the material is guided to the next roll unit in the sequence until it reaches the final desired dimensions.
Cooling and Finishing: After the rolling process, the finished product may pass through cooling systems to control temperature and improve mechanical properties. Additional finishing processes, such as cutting to length, may also be performed.
