Abstract: A particular dispensing apparatus (10) for dispensing with particular refractory material into a gap between a furnace wall and a form includes a platform (12) removably engaging the upper end of an expendable metal form. A carriage (14) is pivotally coupled to the platform and is rotatable about a pivot point located generally at the center of the platform. A hopper (30) is coupled to the carriage. The hopper receives particulate refractory material via an inlet and dispenses the particulate refractory material through an outlet (36). A feeder (34) is coupled to the outlet of the hopper to move the particulate refractory material from the outlet to a dispenser (44). The dispenser is coupled to the carriage at a distal end of the feeder and is suspended above the lining gap to deliver particulate refractory material into the lining gap.

Abstract: A spacing tool to be inserted between a form and a foundry furnace during installation of the form in the foundry furnace comprises a first longitudinally extending member to contact the foundry furnace. A second longitudinally extending member is coupled to the first member. The first and second members define opposed surfaces to contact the form and foundry furnace respectively. The second member is moveable relative to the first member to alter the distance between the opposed surfaces and set the spacing between the form and the foundry furnace. During a foundry furnace relining process, a plurality of spacing tools are used at circumferentially spaced locations to center the form within the foundry furnace.
