High-impact bars in automobile doors, steel girders supporting skyscrapers, and even the foil wrapping your sandwich all have one thing in common: they were once ore or scrap metal that was melted down and carefully combined with additives before being formed. 

Melters, furnace operators, blowers, and keepers oversee and regulate vessels and furnaces that melt and purify metal before it is placed into a mould to manufacture a product. They might work in a variety of metal refineries, foundries, and scrap metal recycling plants. 

They control the process of producing iron, which is then refined into steel in integrated steel mills. Steel furnace operators and furnace keepers are among the mill's highest-paid production workers. While they may spend some time in the hot, noisy furnace area, steel furnace operators are most likely to be located in an air-conditioned pulpit control room, running computers and monitoring visual displays. 

The furnace operator monitors the amounts of scrap, hot metal, and additive utilised and makes adjustments as needed using computerised charge models. He or she is in charge of maintaining the right raw material ratio as well as changing the furnace temperature. The furnace operator then utilises the controls to purify the iron into steel. After that, the molten metal is tapped into a ladle, which is then utilised to pour the steel into a mould. The mould will produce a steel slab. 

All data generated during the iron and steel manufacturing process is recorded in a computer system. A solid understanding of basic arithmetic, a high school diploma, and on-the-job training will enable you to progress from an entry-level position to the control room. 

Being adaptive and eager to stay up with technology may 'hot up' your chances of landing a job in this sector.
