A Study on the Production of Regenerated Pig Iron (4th Report)

Minoru Yohda


Abstract:

In the production of regenerated pig iron, small blast furnaces areused sometimes, but to obtain iron suitable for casting as well as iron castings directly, regenerating cupolas (cupola type furnce) are generally used: in the present study, the latter kind of the furnace is used. The experimental result shows us that (1) the pressure of the blast in the present case is similar to that in the ordinary cupola because the furnaces are of similar heights, while (2) the amount of the blast rather resembles to that in the blast furnace because the reactions taking place in the furnaces the reduction of oxides, the absorption of carbon and silicon in iron, etc.… are alike.
