Question

In the basic Bessemer process for the manufacture of steel, the lining of the converter is made up of Lime. The slag formed consists of ${\mathbf{C}}{{\mathbf{a}}_{\mathbf{3}}}{({\mathbf{P}}{{\mathbf{O}}_{\mathbf{4}}})_{\mathbf{2}}}.\;$
If the statement is true enter 1, else enter 0.

Answer 1

To answer this question you must recall the concept of the Bessemer Process. The Bessemer process is involved in the extraction of iron from its ore.

Complete step by step answer:
The Bessemer process was the first industrial process that was inexpensive and was used for production in the bulk of steel, from molten pig iron before the open blast furnace was developed.
The key principle is the removal of impurities from the iron using the process of oxidation of molten iron by air being blown on it. This process also increases the temperature of the iron mass and maintains it in the molten state.
In Bessemer, the manganese and silicon oxides eliminate manganese silicate.
In the basic Bessemer process for the manufacture of steel, the lining of the converter is made up of lime.
The slag formed consists of ${\mathbf{C}}{{\mathbf{a}}_{\mathbf{3}}}{({\mathbf{P}}{{\mathbf{O}}_{\mathbf{4}}})_{\mathbf{2}}}.\;$ Phosphorous is oxidized to ${P_4}{O_{10}}$ which reacts with lime to form slag: ${P_{4}} + 5{O_2} \to {P_4}{O_{10}}$ and $6CaO + {P_4}{O_{10}} \to 2C{a_3}{(P{O_4})_2}$.

Hence, the given statement is true and the answer is 1.

Note:
Do not confuse between the Bessemer process and the Bessemer converter. The Bessemer process was developed for production of steel and it was the first inexpensive industrial process for the mass-production of steel from molten pig iron before the development of the open-hearth furnace. The key principle is the removal of impurities from the iron by oxidation with air being blown through the molten iron. The Acid Bessemer suffered a decline in favour of the Acid Open Hearth steel process, mainly due to economic factors. Also the open-hearth process gives better quality steel than the Bessemer process.
