Experimental study on the effect of velocity of air and coke on the performance of cupola furnace.

The melting of ferrous metals and alloys is frequently done in a cupola furnace. The objective of this paper is to study the effect of input parameters of cupola furnace such as velocity of air and amount of coke supplied to the furnace. The overall effect of these parameters are studied on parameters like melting rate, pouring temperature, hardness and stress. The experimentation was conducted at C. P. Foundry Works which is located at central India. The experiments were performed at three levels each for melting rate, pouring temperature, hardness and stress. It is found that the optimum performance of furnace get at velocity of 36m/s and 598 kg/hr. The maximum melting rate, pouring temperature, hardness and stress are found as 4000 kg/hr, 1406.250C, 207MPa and 19.75 MPa respectively. [ABSTRACT FROM AUTHOR]
