The important advantage(s) of Lintz and Donawitz (L.D.) process for the manufacture of steel is (are)

Options

  1. Athe process is very quick
  2. Boperating costs are low
  3. Cbetter quality steel is obtained
  4. Dscrap iron can be used

Correct answer

D. scrap iron can be used

Step-by-step solution

Lintz and Donawitz (L.D.) process is an important process for manufacturing of steel. In India, Rourkela steel plant is based upon this process. This process is carried out in a converter similar to bessemer converter having lining (usually refractory made of Mg O and ( CaO ) . In this method scrap iron can be used along with flux in converter : On passing oxygen gas at 4-12 atm pressure into converter, temperature of 2000-2500^ C range produced which separates C. Si, Mn etc., impurities as slag from iron quickly r
