Ductile iron smelting scrap increase the proportion of measures

- Mar 10, 2021-

In the traditional production process of ductile iron, about 10% of carbon scrap is generally used for ingredients. This article only deals with some issues that should be paid special attention to in the production process after increasing the proportion of carbon scrap when producing ductile iron in an induction furnace. 1 . The choice of charge ; 2 .Smelting and smelting process: coke block + scrap steel→electrode block→temperature increase→pulled out coke block and electrode block→sampling and analysis of carbon content→pig iron→recycled material→sampling and analysis of Si , Mn →temperature increase→ferromanganese + ferrosilicon→ Baking → inoculation + spheroidization → pouring.
