The New Plant: HWI’s Advanced Monolithic Refractories

South Point Plant Rendering

With a history that spans more than 150 years, HarbisonWalker International (HWI) has created many of the refractory industry’s most significant technologies.

Monolithic refractories (those which can be molded or shaped for a variety of requirements) pose one of the strongest product growth categories for both HWI and the industry. For HWI, the new state-of-the-art plant will enable the company to further elevate product quality and consistency, and it illustrates the company’s forward-thinking strategy to harness new technology and invest for future growth.

HWI expects initial capacity at the new monolithic plant to be approximately 80,000 metric tons per year. The plant will feature new state-of-the-art automation and technology, and will utilize new lean techniques throughout its operations to maximize material flow efficiency and production. It will employ highly-trained and highly-skilled technicians and staff in a team-based environment. In addition, the facility will introduce advanced packaging technologies that are new to the North American market.
