SAF/EAF/RF/RSF/PHS/RMHS

INTRODUCTION

Submerged Arc Furnace (SAF) for ferro-alloy produces various kinds of ferro-alloy such as Fe-Mn, Fe-Ni, Si-Mn, Fe-Si and MG-Si melting raw materials down with electrical power.
To make ferro-alloy of high-purity, which is produced by Submerged Arc Furnace (SAF), Electric Arc Furnace (EAF) and Refining Furnace (RF) provides high efficiency of work with improved process.
We have an ability to execute EPCC (Engineering, Procurement, Construction and Commercial) successfully. Moreover, it is possible to supply all the auxiliary utilities required for ferro-alloy plant.

Sinter Plant & Ore Processing Plant

SINTER PLANT

Sinter Plant is required for transforming the unuseful mid-low class fine ore to high class and also minimizes the amount of electric energy and cokes used for increasing the pre-reduction rate.
We have an ability to execute EPC (Engineering, Procurement, Construction) successfully.
Moreover, it is possible to supply all the auxiliary utilities required for Sinter plant.
