The rapid development of EAF-based steel-making has resulted in the stressful electrical conditions for using refractories. The refractories used for the EAFs’ domes should have superior resistances against spalling and infiltration, and be easy to use for efficient maintenance.
Chosun Refractories contributes to the efficient use and productivity improvement of refractories by producing the best quality products based on thorough quality control, research and testing.

A range of special refining processes within the ladle for special and stainless steel production have caused highly stressful conditions for ladle use. Therefore, Chosun Refractories does its utmost to supply superior product quality by developing the materials adequate for various operating conditions.

The reheating furnaces used in steel mills, steel-making factories and heat treatment companies are largely divided into Pusher Type and Walking Beam Type. Chosun’s refractories for a range of reheating furnaces have been well received. Lately, the company has participated in reheating furnace construction and alteration, exerting collaborative efforts for stabilizing clients’ facilities through technical support and guidance.
