29/August/2020   William Strutt was working in a mill, built with timber. He was a cotton spinner who wanted to protect his mill from fire, because he was working with inflammable substances. So, he encased timber with iron to make it fire resistant. Later this addition of iron to building construction was expanded from casing the structure to making it the structure itself! So, from then, building framework was made out of Iron. This not only made the building fire resistant, but also very strong compared to the previous one which was made of timber.   Later, this solid iron framework was replaced by hollow sections. This not only provided insulation, but also reduced the construction cost by 30%. Later this usage of iron in construction was not just limited to the framework, but also started to expose itself in facades.   All this was around England and New York. In 1869, Chicago fire had crushed off around 17500 buildings and made a lot of residents homeless. So, t...

A documentary [1] , dating to the time of World War II, Ohio.     The process of steelmaking, from the assembling of the raw materials to the final rolling process, can be seen in the sharp black and white video. To watch something that is new to the eyes was  Steel as a usable material goes through a lot of processes, for us to have the steel what we see in our daily life; from finishings and heat treatments to surface treatments depending upon its intended use.  Heat treatment   After rolling, the steel material which has already been cast and rolled into the required forms, steel is heat-treated to improve its strength, hardness, and ductility.  Quenching  The steel is heated and cooled suddenly in water or oil bath A crystal-like layer is formed. The process protects the steel from the effects due to exposure to the atmosphere. Tempering  To increase the strength, hardness, and ductility The steel ...
