In the BOF (BasicOxygenFurnace) process pure oxygen at supersonic speed is blown vertically through a lance onto the surface of hot molten metal contained in a cylindrical-shaped converter.
The reactions involving the oxidation of metalloids are highly endothermic
The exit gas generated during blowing is rich in CO₂
The converter contents often overflow through the tap hole or get ejected through the mouth opening and this is referred to as spitting (for metal droplets) or slopping (for slag-metal emulsion).
The BasicOxygenSteelmaking (BOS) process takes liquid iron plus recycled scrap steel, and reduces the carbon content to 1 to 1.5 percent by blowing oxygen through the metal in a "converter".
Steel making process occurs at approximately 1500 degrees Celsius
Which of these is a raw material in steel making?
Iron ore, Coal, Limestone
What are the three raw materials used in making steel?
Iron ore, coal and limestone
Limestone is added to the steel-making furnace to remove the acidic impuritie
What is the name of the process used to make steel from iron?The Basic Oxygen process
What is the reducing agent in the blast furnace?Limestone
On average, modulus of elasticity (Es) for mild steel is 205GPa
What is the [approximate] density of steel
8 tonnes/cubic metre
What is the chemical symbol for iron
Fe
Which element is it essential to add to iron to make any kind of steel?
