Installation Case

   Iron and steel making, heavy industry equipment

Smelting iron ores is one of the processes in steelmaking. 
The process of removing impurities (carbon) from pig iron is how steel is made.

High performance steel products are made by using acid and alkaline solutions (sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid, phosphoric acid, caustic soda) at various steps of steelmaking processes which include pretreatment, electrolytic cleaning process, vacuum degassing, alloy addition, inclusion removal, inclusion chemistry modification, de-sulphurisation, and homogenization. 
Because potent additives are used, worker safety and the handling of wastewater need to be taken seriously.
YUMINST is a supplier to “P” Steel in Pohang and also to steel mills in the Gwangyang industrial area. 
Our products are also used in the deoxidation and plating processes at “K” Steel's mill in Incheon and Dangjin.
