Manufacture of Steel by Bessemer Process
Molten pig iron from the blast furnace is stored in a mixer to keep the pig iron molten and at an identical temperature and also keep the composition of the molten metal from dissimilar lots quite uniform.
Bessemer is tilted on its side to receive molten iron from the mixer. Then Bessemer is brought back to vertical location and air is blown in at a pressure of 20 lbs. per square inch. The air will combine with molten metal. Dark red flames mixed with brown flames will come out of the mouth of the convertor in the beginning showing the burning of silicon and manganese. With these flames particles of molten iron and molten slag also come out.
