उत्तर
England had a number of iron mines but it was necessary to advance the technique of smelting iron in order to acquire purified iron from it. Gradually the fuel for iron furnaces was replaced from wood to coal. It facilitated the creation of furnaces that could attain much higher temperatures resulting in increased production of iron. Later, special machines were made to keep the furnaces burning at a set temperature and to maintain their aeration. In 1865 the process of producing steel from molten iron was invented and the nature of the iron industry underwent a major transformation. At about the same time, a method was developed to pour the molten metal into casts for making iron bars (for example, rails).
