The safety requirements on machinery and equipment for continuous casting of steel have been updated.

EN 14753:2022 applies for plant (containing machinery and equipment) used in the process of continuous casting of liquid steel.

This document deals with hazards and hazardous situations related to machinery and equipment for the continuous casting of steelused as intended and under conditions of misuse reasonably foreseeable by the manufacturer.

This standard specifies the safety requirements to be met during design, assembly, transport, commissioning, operation, maintenance and decommissioning of the equipment.

It assumes that:

  • the machinery and equipment of the plant is operated and maintained by adequately trained and competent personnel and
  • the machinery is used with adequate workstation lighting conforming to EN 12464 1.

Manual intervention for setting, adjustment and maintenance is accepted as part of the intended use of the plant.

National regulations regarding lighting should be considered and could differ from requirements of EN 12464 1.

This document applies to:

  • continuous casting machine (CCM) for the transformation of molten liquid steel into solid products in sections (e.g. square, rectangular, beam blank, circular)
  • CCM's from the point where overhead cranes or other transport systems deposit ladles to CCM (e.g. in a ladle turret, ladle car or ladle stand)
  • via casting process and solidification process
  • via cutting and marking equipment
  • thru the run-out-area where the cut product is finished, collected and removed from that area.

This standard does not cover safety requirements for:

  • horizontal-CCM for steel
  • auxiliary plants (auxiliary plants that are outside of the limits of the CCM)
  • ladles and ladle transport
  • cranes
  • winches and hoists
  • conveyors or handling systems
  • workshop equipment (mould and segment shop, tundish workshop)
  • gas burners, e.g. as a part of pre-heating stations.

It can be used in case of modernization for the parts to be modernized, but it is not applicable to CCM's manufactured before the date of its publication.
