Refractory benefits of precast refractory shapes are related to simplified installation and repair logistics, which can reduce costs and down times. Using precast shapes eliminates forming labor, materials, equipment costs, actual placement time and expense, and associated costs during form removal, curing, and cleanup. It shifts these costs back to the manufacturer of the shape, who can absorb them much efficiently by spreading them over the overall production capacity. Refractory installation contractors have begun to consider precast refractory shapes much like they do any other pre-manufactured item such as block insulation, ceramic fiber blanket, anchors, etc. These items can be bought
