How did the kelly-bessemer process make iron and steel production better?
a.) it brought temperatures down so that the iron or steel could harden more quickly.
b.) the process enabled manufacturers to make steel at a far greater rate.
c.) it mixed impurities in the iron ore enough to eliminate the problem of weakening.
d.)it shot air into the molten iron, making it hotter and eliminating impurities.

D) It shot air into the molten iron, making it hotter and eliminating impurities.

The Kelly-Bessemer process consists of removing impurities from the iron by oxidation with air that is blown through the molten iron. This raises the temperature of the iron mass and keeps it molten. The Kelly-Bessemer process was the first inexpensive industrial process for the mass production of steel.

The process is named after the inventor Henry Bessemer in 1856, although it is said to have been independently discovered by American inventor William Kelly in 1851.

The correct answer is D) it shot air into the molten iron, making it hotter and eliminating impurities.

The Kelly-Bessemer process help make iron and steel production better in that it shot air into the molten iron, making it hotter and eliminating impurities.

This presented represented a great advantage in the production of steel because industries save money to fabricate it in large quantities. English engineering Henry Bessemer was the inventor of the process in 1850 but a similar invention was also developed by William Kelly in 1857. Both inventors worked hard to obtain a cheaper way to produce steel. They injected air into crude iron so the oxygen could"clean" the iron of its impurities.
