Chosun Refractories makes refractory materials, heat-resistant inorganic substances that line the interiors of industrial furnaces and vessels so they can withstand extreme temperatures without melting.

Its products are essential inputs for steelmaking and other heavy industries, which together account for the large majority of its revenue. Listed on KOSPI, Korea's main stock exchange, the company describes itself as the country's leading comprehensive refractory manufacturer, and the business is relatively insulated from seasonal swings because steel production runs continuously year-round.
