The Hwanghae Iron and Steel Complex has recently established a new technical process for improving the quality of steel based on active limestone.
The active limestone production process for it has been set up at the roasting furnace workshop of the complex.
The new process is capable of producing a large quantity of active limestone by using locally abundant limestone and coal.
According to an official of the complex, the technical process for improving steel quality can boost the quality and productivity of iron and steel as compared to previously, while saving much labour, electric power and fuel.
The introduction of this technology, which improves the quality of steel by using high-purity active limestone, is of key importance in the development of the country’s metal industry as one of the national priority projects for the development of science and technology.
The steel workshop of the complex greatly increases the dephosphorization and desulphurization rate and reduces the steelmaking time by using high-purity limestone to improve the quality of molten iron while saving much electricity.
The technology, which now proves very effective in the steelmaking practice, is arousing the interest of officials, technicians and workers in the metal industry sector across the country.
