Blast furnace - Wikipedia

Some blast furnaces use a "double bell" system where two "bells" are used to control the entry of raw material into the blast furnace. The purpose of the two bells is to minimize the loss of hot gases in the blast furnace. First, the raw materials are emptied into the upper or small bell which then opens to empty the charge into the large bell.

  blast furnace – The Steel Story – A Brief History

  Blast furnaces had been developed in the Far East potentially as early as the 1 st century AD, but the first European blast furnaces weren't built until the 15 th century. The key to a blast furnace is the powerful blowing of air onto the metal – this increases the amount of oxygen in the air, increasing the working temperature of the furnace.
