On the basis of the mature localized production technology of high-purity pig iron
On the basis of the mature localized production technology of high-purity pig iron, Hebei Longfengshan New Materials Technology (Group) Co.,Ltd did not stop the pace of technological innovation, but continued to target the higher-end ultra-high-purity pig iron market which was completely occupied by international top enterprises at that time. Ultra-high-purity pig iron has extremely strict requirements on impurity control, chemical composition stability and material purity, and its technical threshold and production difficulty are far higher than ordinary high-purity pig iron, which is a key core basic material restricting the upgrading of global high-end equipment manufacturing. Focusing on the international leading technical standards, the company’s R&D team carried out in-depth technical tackling around ultra-clean smelting, precise impurity removal, constant temperature control and stable forming processes. Through continuous iteration of production equipment, optimization of smelting formulas and improvement of production management systems, the company finally made a major breakthrough in ultra-high-purity pig iron technology in 2017. The independently developed ultra-high-purity pig iron products have reached the world-leading technical level in terms of purity, performance stability and product consistency, surpassing many international peer products in core indicators. The successful research and development of ultra-high-purity pig iron marks that Longfengshan has jumped from a domestic industry leader to a global first-class high-purity iron material manufacturer. It also enables China to possess independent core technology and mass production capacity in the field of ultra-high-purity pig iron, breaking the long-term absolute monopoly of international enterprises in the high-end ultra-high-purity iron material field, and greatly enhancing the international competitiveness of China’s iron-based new materials industry.
