Business Details and Production Items

· Metallic Tube
This product is used in the RF facility for secondary refining in a steelmaking plant. The inside and outside areas are built to be castable in order to protect the tube from high-temperature molten steel. When a dip tube is submerged in the molten steel in ladle, and Ar is injected to the lifted tube, the molten steel is circulated according to the difference in the specific gravity of molten steel from the lowered rube. In this process, the molten steel is decarbonized, nonferrous inclusions are separated, and impurities, such as bubbles, are removed.

· SNNC - Ladle Bottom Bubbling (Auto Coupler) Development
The Fe-Ni mixing facility in bubbling process is installed in the bubbling and LF processes of SNNC refining plant. As Fe-Ni mixing is carried out through automatic injection of nitrogen gas into the ladle, the properties are homogenized. Contributing to quality improvement in premium steel manufacturing, this facility reduces process time and prevents accidents affecting workers.

· SNNC - Electrode Casing
An electrode is inserted to the casing, and ferronickel and subsidiary materials are inserted in between the electrode and casing. Then, Fe - Ni mixture is added to the electric furnace, high-temperature electricity is generated using the electrode to melt the mixture, and it is used to produce the Fe - Ni products.

Features

Since establishment, Hana Tech has supplied tubes and other processing items to POSCO, SNNC, and power plants. Having ac- cumulated technological power for pipe refining and processing, the company has expanded its business area to automatic facility design, manufacturing, and installation.
