Morphology
open-hearth + process
The phrase names a type of method (process) that uses an open-hearth (open + hearth) furnace, so its overall meaning is directly and compositionally derivable from its parts. Although the term is technical, a B1 learner who knows the constituent words would reasonably infer it denotes the method of producing steel using an open hearth.
Etymology
The noun open-hearth process comes from the words open and hearth, meaning an open furnace where workers melted iron and scrap metal in the open air. That's why it means 'a method of making steel' by melting those materials in that open hearth.
