Product Description
According to publicly filed U.S. asbestos personal-injury and wrongful-death litigation records, North American Refractories Company (NARCO) allegedly supplied asbestos-containing refractory castables and gunning mixes used to line Basic Oxygen Furnace (BOF) hoods, off-gas skirts, secondary emission ductwork, and related steelmaking equipment. Plaintiffs allegedly identified NARCO product shipments as a source of occupational asbestos exposure at integrated steel mills.
Litigation records allegedly describe asbestos fiber used as reinforcement and thermal-shock resistance in dry-mix refractory formulations, released as respirable dust when workers opened bags, hand-mixed powder with water, gunned the material through pneumatic nozzles onto hot substrates, and demolished spent linings during BOF hood rebuilds.
