Product Description
Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Norton Company — a major U.S. abrasives and refractories manufacturer — allegedly supplied Norton NORzide branded refractory throat pieces at the melter-refiner interface of glass tanks and asbestos-refractory port neck blocks in the port structure of regenerative glass melting furnaces.
According to publicly filed asbestos litigation records, Norton NORzide throat pieces allegedly served the high-erosion choke zone between melter and refiner, and the port neck blocks allegedly formed the geometry of the fuel/air port throats routing regenerator flow into the melt chamber. Bonding, joint mortar, and back-up refractory around these Norton-supplied shapes allegedly contained asbestos and were allegedly disturbed during tank builds, hot patches, and cold rebuilds of the regenerator/port structure on the 3-8 year glass tank service cycle.
