This paper discusses the control situation of the domestic pig iron silicon content .The cau-ses of high silicon content in pig iron of the ironmaking plant are analyzed .The silicon content of the pig iron is reduced to less than 0.4%, and the success of low silicon smelting is achieved , and, good economic benefits is obtained by adopting some measures , such as improving vibration sieve , increas-ing slag basicity , inhibiting Si reduction and other measures .
