Goal of the chapter 2: Steelmaking and manufacturing
Acquire knowledge about the steelmaking / steel manufacturing process in English.
Brainstorming/Reviewing
Do you remember how we can translate this french words into english
Definition: Metal formed by an industrial process into thin, flat pieces.
The steelmaking process
Step 1: Read the definitions and find out a French translation
- 1) Scrap steel: used steel before being melted and then formed into a new material. =
- 2) Iron ore: a native compound of iron from which the metal may be profitably extracted. =
- 3) Slag: the glass-like by-product left over after a desired metal has been separated from its raw ore. It is usually a mixture of metal oxides and silicon dioxide. =
Step 2: Match the verbs with their translations.
Step 3: Watch the video entitled “The steelmaking process” and take notes.
