Which of the following is used to prepare the inner lining of a blast furnance?

Options

  1. AGraphite bricks
  2. BSilica bricks
  3. CFire clay bricks
  4. Dbasic bricks

Correct answer

C. Fire clay bricks

Step-by-step solution

The inner lining of a blast furnace is subjected to extremely high temperatures and chemical reactions. It is constructed using refractory materials that can withstand these conditions. Fire clay bricks, which are composed primarily of silica and alumina, are commonly used for the lining of the blast furnace because they possess high thermal resistance and structural stability at the operating temperatures of the furnace. Answer: Fire clay bricks
