Coordinate elements of the steelmaking process.
Range
process includes but is not limited to – electric arc furnace, oxygen blowing
machine, vanadium recovery unit, ladle treatment station, casting.
Evidence requirements
1.1

1.3
Sequencing of furnace charge and tap times meets caster schedule and plant
requirements.
1.4
Coordination of the timings of steelmaking elements enables the casting
schedule to be maintained without break.
Outcome 2
Coordinate oxygen blowing machine process.
Evidence requirements
2.1
The oxygen blowing machine temperature maintenance and vessel changes
are operated in accordance with company documentation.
2.2
Monitoring and interpretation of output data enable control parameters to be
adjusted to maintain technical process specifications.
2.3
Communication of process requirements to floor operators enables
achievement of steel temperature and sampling and tapping operations to be
achieved in accordance with company documentation and technical process
specifications.
Range
sampling and tapping operations include but are not limited to –
alloying, temperature testing.
Outcome 3
Control vessel condition.
Range
condition includes but is not limited to – of refractory lining, lance, mouth,
taphole and emissions control.
Evidence requirements
3.1
Monitoring of vessel condition is carried out visually and by alarm system, and
enables company documentation for the maximisation of vessel life to be
achieved.
3.2
Organisation of any remedial action enables plant utilisation requirements to be
achieved.
Range
3.3
remedial action includes but is not limited to – clean, replace,
repair.
Gunning of refractories enables expected vessel life to be achieved.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
