What is a continuous rolling line? What equipment does a complete continuous rolling line include?
source:m.caomm2.com  |  Release time:2025-08-21
  A complete continuous rolling production line typically includes equipment such as a heating furnace, a rough rolling mill, a finishing mill, a tempering furnace, a trimming machine, and a coating machine, among others.
  1. Heating furnace
  The heating furnace is a device that steel ingots to the desired temperature to facilitate subsequent rolling. Electric arc furnaces or induction furnaces, which have relatively high working conditions and environmental protection requirements, are typically used as furnaces in continuous rolling production lines. In addition to heating the steel ingots to the required temperature, the heating furnace can also adjust the internal structure and properties of the steel by the process parameters of the heating furnace.
  2. Rough rolling mill
  The rough rolling mill is a device that presses heated steel ingots into flatter steel plates Typically, a rough rolling mill includes two rolls, and the steel ingots are transmitted into the roll gap, and the steel ingots are squeezed into the desired shape by force. rough rolling mill eliminates defects in the steel ingots and adjusts the structure and properties of the steel by subjecting the steel ingots to good plastic deformation.
  3.ishing rolling mill
  The finishing rolling mill is a device that further processes steel that has already been formed by the rough rolling mill. The finishing rolling mill can further reduce the thickness the steel plate and improve the dimensional accuracy of the steel. The finishing rolling mill uses a series of complex rolls and conveyors, and adjusts the size and quality of the steel by pushing and fixing the steel plate.
  4. Tempering furnace
  The tempering furnace is a device that heats the already processed steel to make it soft and relaxed subsequent processing. In a continuous rolling production line, the tempering temperature is usually high (around 900℃-1200℃), so the steel after is still in a tempered state. If no further processing is performed at this time, deformation or cracks will occur. Therefore, a tempering furnace is required in the continuous rolling line to further process the steel.
  5. Trimming machine
  The trimming machine is used to trim, shape, and cut the continuous rolling bar to meet the of steel quality standards and precise dimensional accuracy.
  6. Coating machine
  The coating machine is used to apply a thin film of oil to the surface of the steel protect the steel plate surface from oxidation and corrosion. Two types of coating machines are typically used in continuous rolling production lines: Tokyo-type and Kass-type coating machines. Tokyo-type coating machine is suitable for higher speed production lines and can ensure a uniform oil film; the Kass-type coating machine is suitable for decoiling production lines and strong coating accuracy and adhesion of subsequent coatings.
  The above are the main equipment included in a complete continuous rolling production line, each with its own emphasis. Through the combination of these devices, the efficient production of the continuous rolling production line is finally achieved.
