Question

I have been asked this question by my school teacher while I was bunking the class.

I would like to ask this question from Cupola Furnace topic in section Melting Furnaces of Foundry and Forging

Answer 1

The correct option is (b) Blowers

The best explanation: Once the eroded material is removed, the eroded refractory lining at the combustion zone is filled with the pneumatically operated gun which blows refractory patching mixture at sufficient velocity so that it sticks properly to the lining.
