A basic oxygen furnace called a BOF is a pear-shaped steel vessel with refractory lining and an open top.The charge consists of about 75 molten iron and 25 scrap steel. Steel is produced in an basic oxygen furnace by the following steps . 1. The charge is dumped into the furnace. 2. An oxygen lance (pipe) is lowered and pure oxygen blows into the furnace at high pressure.
