Elements and Performance Criteria

1. Produce slabs to specification
   • Adjust contents of ladle in accordance with procedures
   • Monitor continuous casting process in accordance with standard operating procedure
   • Apply metallurgical principles to determine and prioritise required actions in accordance with standard operating procedures
   • Record adjustments and variations to specifications / schedules and report to appropriate personnel
   • All events outside of parameters or standard operating procedures is immediately referred to appropriate personnel for remedial action

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria Required Skills and Knowledge the Range Statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to monitor secondary steelmaking operations Critical aspects for assessment and evidence are required to demonstrate competency in this unit
Critical aspects for assessment and evidence required to demonstrate competency in this unit	It is essential that competence is demonstrated in the ability to Use OHampS practices in accordance with standard operating procedures Explain the general principles of continuous casting Monitor the operation of a continuous cast process under direction and consistently achieve required slab output specification
Relationship to other units	This unit may be assessed concurrently with other relevant units
Assessment method and context	Assessors must be satisfied that the person can consistently perform the unit as a whole as defined by the elements performance criteria skills and knowledge A holistic approach should be taken to the assessment Assessors should gather sufficient fair valid reliable authentic and current evidence from a range of sources Sources of evidence may include direct observation reports from supervisors peers and colleagues project work samples organisation records and questioning Assessment should not require language literacy or numeracy skills beyond those required for the unit The assessee will have access to all techniques procedures information resources and aids which would normally be available in the workplace The method of assessment should be discussed and agreed with the assessee prior to the commencement of assessment
Resource implications	This section should be read in conjunction with the range of variables for this unit of competency Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation A bank of case studiesscenarios and questions will also be required to the extent that they form part of the assessment method Questioning may take place either in the workplace or in an adjacent quiet facility such as an office or lunchroom No other special resources are required

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Codes of practice/standards	Where reference is made to industry codes of practice, and/or Australian/international standards, it is expected the latest version will be used.
Metallurgical principles	Post steelmaking methods employed Types of steel - ingot characteristics (Rimmed, capped, killed and semi-killed) Factors contributing to successful casting Mode of solidification Continuous Casting Processes Metallurgical aspects
