, What are a few characteristics of steel? - CORRECT ANSWERS-linear behaviour
high strength
very high modulus of elasticity
high ductility
properties are not directionally dependant (very similar in tension and compression)
An alloy is a combination of metals or of a metal and another element. What is steel an
alloy of? - CORRECT ANSWERS-iron and carbon
What is the maximum amount of carbon present in steel? - CORRECT ANSWERS-2%
Briefly explain the production of steel. - CORRECT ANSWERS-raw materials (iron ore,
coal, limestone)
heat in blast furnace (1600degC)
pig iron is molded (very high carbon contents. 4 - 5%)
oxygen or electric arc furnace
Refining Facility
continuous casting
After pig iron is formed what is the next step - CORRECT ANSWERS-reduce carbon
levels through refining processes
what does an oxygen furnace do? - CORRECT ANSWERS-removes excess carbon &
other impurities
- the carbon is oxidized to carbon monoxide gas, which can be after cleaning can be
used as gas
What is Hot Rolling - CORRECT ANSWERS-Hot rolling is mill process which involves
rolling the steel at a high temperature
slabs are used to make flatter products
blooms and billets used to make long products
