Answer:
Explanation:
The Bessemer process was invented by Henry Bessemer and was used for the production of steel from molten pig iron.
The Bessemer process had the following advantages:
1. Steel could now be produced in bulk
2. The process of making steel became less labor-intensive
3.Due to its small and compact size, major repairs can be carried out within short periods of time
Shortfalls of the Bessemer process:
1. The Bessemer process was not able to remove the phosphorous found in the Pig iron of some types effectively, thus making it inefficient in that aspect
2. Steel produced through the Bessemer process always had retention of a small amount of Nitrogen from the air blast which adversely affected its structural stability and longevity when used for construction.
3. The Bessemer process usually produces inferior quality steel associated with blow holes and inclusions
Both Mayans and Egyptians came up with the idea of constructing pyramids as part of their cultural identity.
