Method of charging scrap and coke materials into cupola

A method of charging an iron scrap melting cupola with iron scrap and coke enables the iron scrap to be melted with high energy efficiency. The charging pipe feed is set at a level "h" which meets the condition of h ≤ (r - r') tan , and iron scrap of a quantity Ws meeting the conditio...

Summary:A method of charging an iron scrap melting cupola with iron scrap and coke enables the iron scrap to be melted with high energy efficiency. The charging pipe feed is set at a level "h" which meets the condition of h ≤ (r - r') tan , and iron scrap of a quantity Ws meeting the condition of Ws ≤ 1/3. pi r .tan . rho s is charged through the charging pipe, followed by charging of coke, wherein h represents the height of the charging feed above the material in the cupola (meters), r represents the inside radius of the cupola (meters), r' represents the inside radius of the charging pipe (meters), represents the angle of repose of the iron scrap (degrees), Ws represents the quantity of iron scrap per cycle (kg/ch), and rho s represents the bulk specific gravity of the iron scrap (kg/m ).
