Lubricants for hot rolling

Hot rolling
Specific maintenance production for lubrication of the reheating furnace, from the rolling mill to the coilers.

Description

After having been reheated to a temperature of the order of 1300°C in the furnace,  the slabsblooms or billets are subjected to plastic deformation between different cylinders: reduction in diameter, thickness, modification of the shape. The hot rolling process thereby allows the manufacture of products such as:

  • slabs
  • sheets
  • Wire rods
  • bars
  • rails
  • profiles
  • steel beams

Characteristics

The different hydraulic systems for the reheating furnaces are subject to fire risks. To eliminate this risk and guarantee the safety of workers and equipment, the use of fire-resistant fluids is recommended.

During the process, the bearing chocks of the working cylinders are subject to severe constraints linked to wash-out, at high temperatures and under heavy loads. The re-greasing time is essential so as to limit maintenance operations between each cylinder change.

Also, the power transmission provided by the couplings and spindles requires lubricants able to resist the centrifugation and  heavy loads.

The coilers are also subject to high temperatures and heavy loads.

The CONDAT range answers these many constraints with a range of high-performance lubricants.

Applications

Fire-resistant hydraulic fluids for:

  • control of the doors for reheating furnaces,
