Chemistry KS4/GCSE: How is steel made?

Fran Scott describes some of the uses of steel and then finds out how it is made from iron that has been produced in a blast furnace.

The carbon content is reduced by blasting heated oxygen onto the molten iron and scrap metal is added to reduce the temperature. Fran helps to test the carbon content of some samples of steel.

The red hot steel is rolled into long sections. The carbon content of the steel affects the properties and uses of the steel.

This clip is from the series Real World Chemistry.

Teacher Notes

Ask students to explain how the carbon content affects the properties and thus the uses of different types of steel.

Challenge them to summarise the basic oxygen steelmaking process as a flowchart.

Curriculum Notes

These clips will be relevant for teaching Science and Chemistry at KS4 in England, Wales and Northern Ireland and National 4/5 in Scotland.

The topics discussed will support OCR, Edexcel, AQA, WJEC GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 4/5 and Higher in Scotland.
