Aluminum

Start with who needs aluminium ingots, billets and sheet and why. Around car makers, building facade firms and packaging makers drive demand in Dubai, Abu Dhabi and the other emirates.

• List 10 offers or suppliers in the UAE with price per tonne in AED and who buys.
• Interview 5 people from car makers, building facade firms and packaging makers: what do they buy now, how often, what do they pay, what annoys them?
• Learn three terms: Smelting (using electricity to turn alumina into metal); Billet (a round or square bar cast for later shaping); Dross (waste skimmed from molten metal).
• Write a one-page brief: user, need, hoped-for price, and the rule that matters most.

Activity. Complete the market table, five interview notes and the brief.

Standard to meet. Price ten offers, interview five users, and state one need in one sentence.

Know the rule before the work. Main hazards here: molten metal burns and electrical hazards. Hazard thinking means list each step, ask what could go wrong, and decide the control.

• Ask your local authority or free zone which licence, permit or inspection applies. Write the answer and the date you asked.
• For each step (melt; cast; cool and cut; test and dispatch) write the hazard and the control.
• Use a hierarchy: remove the hazard, replace it, separate people from it, change the way of work, then protective equipment last.
• Keep a one-page incident rule: who you call, what you stop, what you record.

Activity. Draw the flow and mark hazard and control at each step.

Standard to meet. Name a hazard and a control for every step, and answer the licence question in writing.

The work is a short chain: melt, cast, cool and cut, test and dispatch. Learn each link, then link them with records.

• Write a checklist for each of the 4 steps: input, action, check, output.
• Time each step three times and note the slowest.
• Record a defect or delay each time it happens: what, where, cause, fix.
• Measure tonnes cast within specification; this is your main number.

Activity. Run the chain three times (simulated or real) and fill the log.

Standard to meet. Complete three logs, and give the slowest step a cause and a fix.

What you do not measure you cannot improve. Your main measure is tonnes cast within specification.

• Define tonnes cast within specification: what counts, what does not, and over what period.
• Draw a simple chart of the last 10 results and mark the average.
• Find the top two causes of loss with a tally sheet, then fix the biggest one first.
• Check measuring tools: are they accurate, clean and in date?

Activity. Collect a tally for one week and make a Pareto chart.

Standard to meet. Complete the tally, name the biggest cause, and plan one fix with a date.

Know the cost of one tonne before you set the price. Include materials, labour, energy, transport, licence share, waste and a safety margin.

• Cost per tonne = total cost divided by tonnes sold (not made).
• Margin = (price minus cost) divided by price.
• Break-even units = fixed costs divided by gain per unit.
• Test the price with two users and write down the answer.

Activity. Build the cost sheet with AED on every line and have your mentor check it.

Standard to meet. Check that no cost is missing, and calculate the margin twice by different routes.

Customers return when you keep promises. Promise only what your workflow can deliver.

• Write a one-page offer: what is included, what is not, price, time, how you fix mistakes.
• Write a short script for the first call or visit.
• Agree dates in writing; confirm each change.
• Handle a complaint in four steps: listen, apologise for the impact, fix, record what changed.

Activity. Present the offer to two users and note changes.

Standard to meet. Write an offer with scope, price, time and a fix rule, and collect comments from two users.

Small, real and recorded. Change one thing at a time and learn quickly.

• Keep a daily log: date, units, cost, delays, defects, safety notes.
• Hold a 15-minute review each week with your mentor.
• Write down every complaint and what you changed.
• Take photos only where allowed and never of people without consent.

Activity. Complete 30 days of the log and four weekly reviews.

Standard to meet. Log 30 days, give each defect a cause, and keep weekly notes.

A decision beats a feeling. Compare plan with result and choose to scale, change or stop.

• Make a before and after table: cost per unit, defects, delays, repeat users.
• Write three lessons.
• Decide scale, change or stop, with the numbers behind it.
• Give two peers one strength and one fix each.

Activity. Present to a review room and collect one written comment from a user.

Standard to meet. Justify the decision with numbers, and give two peer reviews.

Making metal from its oxide uses large electric current day and night, so power cost and stability shape everything.

• Energy per tonne (kWh per tonne) is the key cost number; track it daily.
• A power dip can freeze a production cell, so planned power cuts are rare and well warned.
• Efficiency is the share of current that actually makes metal; losses show up as heat.
• Heat is useful but dangerous: hot cell surfaces and spilled metal can burn you even from a distance.

Activity. Calculate energy cost per tonne for a week of sample data and mark the days above target.

Standard to meet. Show units, calculate the AED cost per tonne correctly, and explain the days above target.

Water meeting molten metal can explode. Every mould, tool and charge must be dry.

• Preheat tools and moulds; check for damp before each pour.
• Wear the full rated clothing: face shield, heat-proof coat, boots over trouser legs.
• Keep a clear escape path and a second person watching.
• Skim dross and weigh it; dross is lost metal and a measure of care.

Activity. Write a dry-check list for a casting shift and mark who signs each item.

Standard to meet. Obtain a signer for every item, and draw the escape path.

Customers do not buy 'aluminium'; they buy a grade with stated composition and strength.

• Know that small additions change the metal: strength, flow, finish.
• Each cast is sampled and the composition tested before release.
• Out-of-grade metal is recycled into a lower grade or remelted.
• Match the grade to the end use: facade profile, car part or foil.

Activity. Match five end uses to grades from a list and explain each match.

Standard to meet. Justify the matches by composition or strength.

On the slide: L1 Basic · Aluminium from ore to ingot

Notes: Name smelting, billet and dross and the hazards of molten metal burns and electrical hazards. Notes: use pictures only; learners stay out of the casthouse and ask a supervisor before any visit.

On the slide: L2 Awareness · Water and molten metal

Notes: Explain why a damp tool or mould can explode on contact with molten metal and name the full protective clothing. Notes: show a damp ladle on a rack and ask what to do; tag it, set it aside and delay the pour.

On the slide: L3 Foundation · Write a dry-check list for a pour

Notes: Write a dry-check list for a casting shift with a signer for each item and a drawn escape path. Notes: work only under a competent supervisor; check preheated tools, a second person watching and the full rated clothing.

On the slide: L4 Practitioner · Calculate energy cost per tonne

Notes: Apply a week of sample data to find kilowatt hours per tonne and the AED cost, and mark the days above target. Notes: 14,000 kWh against a target of 13,500 is 500 extra at AED 0.2, so AED 100 more per tonne; show units on every line.

On the slide: L5 Specialist · Match grade to end use and decide

Notes: Evaluate a cast that is out of grade and decide to sell it for a lower use or remelt it, with the certificate showing true composition. Notes: at AED 9,500 price and AED 8,300 cost the gain is AED 1,200 a tonne, a margin of 12.6 per cent, so a small price drop matters.

On the slide: L6 Advanced · Coach a shift on pour safety and dross

Notes: Lead a casting team in dry checks, escape paths and weighing dross. Notes: sample five shift check lists a week for a missing signer; a rising dross weight is lost metal and a sign of poor care.

On the slide: L7 Super expert · Design the energy and casthouse system

Notes: Design an energy, casting safety and grade-control system for a casthouse with an audit and a 12-month plan. Notes: at 120 tonnes an extra AED 100 a tonne costs AED 12,000, so present energy per tonne, one safety risk and one saving.
