Abstract
Herein the synthesis of iron-carbon saturated alloys (foundries) melting in cupola furnaces from direct reduction iron is described. The fundamentals are reviewed and combinations undertaken are discussed along with their results, including conclusions and recommendations for follow up.
Highlights
The cupola (American Foundrymens Society, 1965) is a shaft furnace whose primary characteristic is its height. (Fig. 1)
The values of carbon and silicon for each melt sample can be seen in Table 3, as well as those for the Carbon Equivalent (CE)
Carbon self-regulates in the furnace, unlike silicon which depends on charges of ferrosilicon
Summary
The cupola (American Foundrymens Society, 1965) is a shaft furnace whose primary characteristic is its height. (Fig. 1). The cupola (American Foundrymens Society, 1965) is a shaft furnace whose primary characteristic is its height. It is a counter current heat exchanger. Air enters through tuyeres and burns the coke inside, releasing heat (Enríquez and García, 1993). The iron introduced in the charging door is heated and melted by rising combustion gases. The melted metal drips through the coke bed and falls to the hearth, draining out through the tap hole. The high level of thermal efficiency of this type of furnace allows the melting of any material
