Q1:

Pick up the correct statement from the following:

A In basic Bessemer process, the steel heats the converter

B In open-hearth process, the furnace heats the steel

C In Siemens process, the impurities of pig iron are oxidised by the oxygen of the ore

D all the above.

ANS:D - all the above.

The Bessemer Process was the first inexpensive industrial process that allowed for the mass production of steel. Before the development of an open-mouth furnace, the process used a molten pig iron to melt iron. The real difference with this process was that air was forced through the molten iron to remove impurities.
