Advanced Design & Engineering

Lechler are continually developing new advanced roll cooling Technologies such as the next generation of Integrated Closed Loop Roll Cooling for multi-stand mills utilising state of the art touch screen operational interfaces with closed loop feed back to upstream stands ensuring optimum cooling and lubrication application in  both cold and hot  rolling mills.

Design Priorities

Design Priorities

  • Optimised homogeneous spray pattern / impingement onto work roll
  • Symmetrical spray application for upper and lower rolls ensuring
    • Uniform roll wear on top and bottom work rolls.
    • Minimised differential in friction and heat generation on top and bottom work rolls
    • Uniform deformation characteristics on top and bottom work rolls

Header Technology

Header Technology

 

  • CFD design of headers and valves optimises flow and pressure characteristics and specific designs are aimed at the efficient use of restricted mill space.
  • Selectospray® equipment is produced in-house by Lechler UK in Sheffield, employing the latest in welding and machining technology. Very robust and reliable construction is featured throughout – including main elements headers, valves, nozzles, hoses, cabinets.
  • Headers are machined from stainless steel forgings or heavy duty stainless steel plate to ensure robustness and durability when mill wrecks, high speed strip breaks and other catastrophic event occur during rolling.
  • Headers and system hardware is specifically designed to utilise existing connections and mountings where possible to facilitate ease of installation.
  • All ancillary parts are machined from stainless steel, delivering system durability in service.

Precision Machining is carried out on state of  the art machining centres and the latest advanced welding techniques are deployed to ensure optimum robustness, integrity and precision.
