The trial products are of great economic significance as they are higher in grade than the previous one and lower production cost with locally available raw materials and have good metallurgical engineering characteristics.

They have been introduced into a metal factory, to prove effective.

It is said that they have good metallurgical engineering characteristics including deoxidation and desulphurization and help improve the machine processing characteristics of steel and the quality of casting products.

Officials, technicians and skilled workers of the Puryong Ferroalloy Factory are striving to produce more new and high-grade ferroalloy while stepping up the work to produce the already researched trial products with an industrial method.
