In 1858 Shepard found a metal in meteorites containing 87.28% Fe, 11.01% Si and suggested the name ferrosilicon. In 1810, J.J.Berzelius, a Swede, smelted five kinds of ferrosilicon containing 2.2% ~ 9.3% Si in a forge furnace using scrap iron, quartz stone and pine charcoal. According to reports by E. J. Davis and A. D. Gate, the United States produced 6 to 16 percent si of ferrosilicon at a blast furnace at Globe Steel in 1872. In 1875, A.Pulcel refined iron silicon containing 10% ~ 18% SI in the blast furnace in Ternoy. In 1899 DuCholmol smelted 25% ~ 50% Si of ferrosilicon in an electric furnace at Wilson Aluminum Company's Holcombe Rock plant in the United States and obtained an American patent. Later, electric arc furnace replaced blast furnace to produce ferrosilicon, and mainly produced 75% Si and 50% Si. Before the 1950s, chongqing, China, used electric furnaces for trial production of ferrosilicon, and Anshan produced ferrosilicon in 400-1200 kVA electric furnaces. In 1952, Fushun Aluminum Plant began to produce 75% Si of ferrosilicon using 6000kVA furnace. In 1956, Jilin Ferroalloy Factory began to produce 45% Si of ferrosilicon with 12500kVA furnace, and later produced FeSi75.
