Hi All the below Questions are related to the GI Foundry. Please clear my doubts. 1. What does the "GI" stand for in a "GI foundry" which is otherwise known as Ferrous Foundry? 2. What is the 'Sintering Cycle" of an induction furnace? 3. What is the difference between swarf and scrap? 4. What is a band saw cutting machine? Thanks.
