Question

Henry Cort introduces the process for the purification of pig iron.
(A) Weaving
(B) Spinning
(C) Puddling
(D) Smelting

Answer 1

Hint:Pig iron is an intermediate product in the iron and the steel industry has a very high carbon content which makes it not used directly as material.it is a semi finished product which is used in making cast iron, rod iron, etc in the different furnace and different temperature. This is the most impured iron as it is a semi finished product and silica, manganese, phosphorus, and sulfur are also present in it.

Complete answer:
Pig iron is made on a blast furnace.
Henry Cort introduces the process of purification of pig iron which is known by the name of puddling he was an English ironmaster during the period of the industrial revolution in England. He used many innovative systems for purifying the iron Puddling is a processor’s first step to manufacture high-grade iron in a crucible or furnace.it was invented in Great Britain during the Industrial revolution. Though it was not the first process to produce bar iron without charcoal puddling was by far the most successful process which replaced the earlier process of potting and stamping. This puddling process enables the great expansion of iron production in Great Britain. Later furnaces were also started to be used to make the good carboned iron and steel.

Hence, the correct answer is option (C).

Note:As the pig iron is a semi finished iron so it takes a long process to be used as material as many impurities and chemicals were present in it.it helped greatly in the expansion of the iron and steel industry. Much fuel and high temperature are needed to get the process completed and use it for the work.
