Abstract
A shield for a refractory structure that houses refractory bricks. The refractory bricks are assembled with respect to each other to form a refractory wall, roof or another refractory structure. A hanger can be used to suspend or mount at least one refractory brick. In order to extend the service life of the hanger, a shield can cover at least a portion of the hanger, such as a hanger rod, to prevent dust particles from accumulating on the rod or another hanger element. Reducing or eliminating dust particles, particularly metal dust particles, can extend the service life of hanger components and can also reduce costs associated with maintenance and repair of refractory structures, particularly within industrial furnaces.
