IMOS Test 2 QUESTIONS AND ANSWERS| GRADED A
wrought iron Correct Answer: a tough, malleable form of iron suitable for forging
or rolling rather than casting, obtained by puddling pig iron while molten. It is
nearly pure but contains some slag in the form of filaments
steel Correct Answer: a strong, hard metal made of iron and carbon
cast iron Correct Answer: molten iron poured into a mould to make a product
Bloom Iron Correct Answer:
pig iron Correct Answer: a type of iron produced by smelting iron ore with coke;
of lower quality than wrought iron
bloomery Correct Answer: factory where iron bars are manufactured
Quenching Correct Answer: Cooling a hot piece of metal rapidly, as in water or
oil.
coking Correct Answer:
Bessemer Furnace Correct Answer: This was developed by a French engineer, and
it could produce large amounts of inexpensive steel by blowing hot air through
molten iron and coke to remove the impurities.
BOP Correct Answer:
Mg alloys Correct Answer:
Lavoisier Correct Answer:
Phlogiston Correct Answer: a substance supposed by 18th-century chemists to
exist in all combustible bodies, and to be released in combustion.
Hall-Heroult process Correct Answer: the process in which the alumina is
dissolved in the mineral cryolite and electricity is used to remove aluminum metal
