MEM04001
Operate melting furnaces


Application

This unit of competency defines the skills and knowledge required to operate melting furnaces.

It applies to the operation and operational maintenance of furnaces primarily used for continuous or staged bulk melting/smelting of a range of metals, holding of hot liquids, or the melting of metals for production processes, such as casting, moulding and galvanising.

Where the interpretation of technical drawings is required unit MEM09002 Interpret technical drawing should also be selected.

Where the selection and use of engineering measuring equipment is required unit MEM12023 Perform engineering measurements should also be selected.

Where the selection and use of tools is required unit MEM18001 Use hand tools and unit MEM18002 Use power tools/hand held operations, should also be selected as appropriate.

No licensing, legislative or certification requirements apply to this unit at the time of publication.
