Product Description

According to publicly filed U.S. asbestos personal-injury and wrongful-death litigation records, Harbison-Walker Refractories Company allegedly supplied asbestos-bonded fireclay and high-alumina refractory brick used in blast furnace hearths, bosh sections, stack linings, tuyere zones, and hot-blast stove checker work at integrated steel mills. Plaintiffs allegedly identified Harbison-Walker brick shipments as a source of occupational asbestos exposure during furnace relining and stove-rebuild campaigns.

Litigation records allegedly describe asbestos fiber used as a binder and reinforcement additive in select refractory shapes, released as respirable dust when bricklayers cut brick to fit, chipped and demolished spent linings, or hand-mixed asbestos-containing mortar during installation.
