Steelmaking at TISCO (Jamshedpur): traditional primary process used historically Identify which steelmaking process has historically been in operation at Tata Iron and Steel Works (Jamshedpur) as per traditional references. Choose the correct process.

Difficulty: Easy

Bessemer process
Open hearth process
Duplex process
Electric process

Correct Answer: Open hearth process

Explanation:

Context
Traditional examination references cite the open hearth process as historically practiced at TISCO, Jamshedpur (before widespread adoption of basic oxygen/electric steelmaking).

Why not others
The Bessemer process was less suited for high-quality control; electric and duplex routes are used, but the classic answer for older plants/MCQs is open hearth.

Final Answer
Open hearth process
