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.
||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 size - cross sectional area of cupola.|
Shell size - thickness of plate, lining dimensions etc.
Selection of Blower.
|| 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.
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. |
