1.	Carbon pickup does not depend on which of the following factors?(a) Size of coke(b) Height of coke bed(c) Cupola temperature(d) Cupola diameterI have been asked this question in an online interview.My doubt stems from Air Requirements and Metallurgical Control for Cupola topic in division Metal Furnace and Practice of Casting-Forming-Welding II
Answer» Right choice is (d) Cupola diameter Easy explanation: MAGNITUDE of carbon PICKUP DEPENDS on various factors such as the PRESENCE of original carbon content, size of the coke, HEIGHT of the coke bed, temperature of cupola and a few more, but it does not depend on the diameter of the cupola.
