Pig iron

Basing on Hanking’s two hundred million tons of high-quality iron ore resources, Fushun D.R.I Co., Ltd. produces casting pig iron and nodular cast iron with the iron concentrates featured by low sulfur, phosphorous and metal impurity from Hanking Mining. Featured by uniformity in lump size, smooth surface, low sulfur, phosphorous and anti-spheroidizing elements, high toughness and wearable, “Hanking” brand pig iron was honored “Gin-seng” pig iron for its super pure. The products are widely used in the fields of automobile manufacture, precision foundry, steel-making and aviation etc.
