Efficient Cupola Operation
	By: Mrs.S.S. Karkhanis
		Dr. Basutkar explains in this lecture:
The design parameters and
The practical details of operating cupola, the most commonly used melting unit in C. I. foundry.
		This lecture will be useful to the owner entrepreneurs and shop floor personnel in foundries using cupola furnace.
	Contents :
	Introduction - An efficiently operated cupola should give high and steady metal temperature, minimum consumption of coke, steady and consistant composition of metal, uniform melting rate and good mechanical properties of metal cast.
	Cupola Design :
		Cupola size - cross sectional area of cupola.
		Shell size - thickness of plate, lining dimensions etc.
		Stack heights.
		Cupola well.
		Tapping system.
		Selection of Blower.
	Instrumentation :
		· Electrical instrumentation.
		· Air control - air velocity, Air pressure and air volume, Air control instruments - pressure gauges and bleast volume meter.
		· Relation between air pressure and volume.
	Trouble shooting :
		Lining maintenance, preparation of tap hole, slag hole. Bed coke height - significance and control. Trouble shooting in cupola operations and precautionary and remedial measures to be taken during operation of cupola.

Productivity Improvement In Foundry Industry
	By: Mr.B.S.Pendse
		In this lecture Mr. Pendse describes:
Productivity in foundry.
Factors on which productivity depends and
How these factors can be controlled.
	This lecture will be very useful for the managerial level personnel and entrepreneurs in foundry industry in evolving their strategies and implementing them.
	Success of any business is essentially dependent on management's ability to maximize output of all types of inputs in a coordinated manner. Foundry industry is not an exception. But being labour intensive discussions about productivity in foundry tend to concentrate on only "labour productivity". In the current wave of liberalization measures for enhancing various day to day operations become important and are focussed in this lecture. Money, materials and Men are basic inputs which control productivity in small / medium scale foundry in particular.
	Contents - Furnaces used :
		Cost competitiveness - through a comprehensive long term approach of maximizing outputs.
		Productivity of capital.
		Productivity of materials and equipment.
		Productivity of Human Resources.
	In conclusion, it must be emphasized that a "do or die" situation is going to be thrust on all small / medium level business serving small niche markets - either domestic or export or both in the near future. It would be essential to realise the irreversibility of this process and to have a sense of extreme urgency in tacking the problems. The complacent approach so far would have to yield to "permanent" and "united " effort to meet the challenges ahead for foundry industry.
