Q1:

In the acid Bessemer process, the hot metal should have the following com-positon.

A S < 0.05% and P < 0.05%.

B S < 0.05% and P < 1.5%.

C S < 0.05% and P > 1.5%.

D S > 1.5% and P < 0.05%.

ANS:A - S < 0.05% and P < 0.05%.

In the acid Bessemer process, which is used for the production of steel, the hot metal (typically pig iron) should have low levels of sulfur (S) and phosphorus (P) to ensure the quality of the final steel product. The correct composition requirement for sulfur (S) and phosphorus (P) in the hot metal is: S < 0.05% and P < 0.05%. High sulfur and phosphorus content in the hot metal can lead to the formation of undesirable impurities and affect the properties of the steel produced. Therefore, to obtain high-quality steel, it is essential to control and minimize the levels of sulfur and phosphorus in the input material.
