Abstract
A continuous checker column is molded and formed in situ inside a regenerative chamber, thereby eliminating the need for large numbers of individual, preformed checker bricks. A plurality of rigid molding rods or flexible cable rods are passed through, or hang from, a template installed in or above the empty checker chamber portion of a regenerative chamber. The molding rods are sized, shaped, and spaced to correspond substantially to the size, shape and spacing of the openings desired in the checker column. Then, a refractory material is injected into the checker column and allowed to harden. The molding rods are at least partially retracted, leaving the desired openings in the hardened refractory material. The injection and retraction steps can be repeated, as necessary, until the entire checker column has been formed.
