Cupola operation improving

The advantages and disadvantages of shaft furnace such as cupola for cast iron smelting are given. In order to diminish the coke consumption and harmful discharges into environment, a cupola design and operational regimes are improved. Heat engineering balance tests of cupolas are carried out via measurements of parameters such as amount and chemical composition of gaseous effluents as well as temperatures of liquid cast iron and gases at the output of cupolas exit and from charge material. The recommendations are given on the basis of the test results.
