open-hearth steel is an important manufacture in Birmingham.
All these parts are made of the finest quality of open-hearth steel.
All the newer steel plants are equipped with open-hearth furnaces.
The Corporation altogether has 335 open-hearth furnaces and 38 converters.
They may be either Bessemer, open-hearth, or crucible steel.
First I flew over in the open-hearth building and landed on a girder.
I entered the open-hearth mill by the tracks that ran close to the furnaces.
I coupled it up with some talks I had had with men on the open-hearth.
But it survives simply because crucible steel is very much better than either Bessemer or open-hearth steel.
But the great mass of the steel of commerce is made by the Bessemer and the open-hearth processes.
