FURNACE CONSTRUCTION AND METHOD OF LOADING AND SEALING A FURNACE CHAMBER THEREIN ABSTRACT OF THE DISCLOSURE A furnace construction capable of withstanding temperatures in excess of 3500°F. A uniquely suspended floor structure permits thermal expansion to occur as required within the furnace while permitting the admis- sion of a cooling fluid to metal plate members there- within. The furnace chamber is provided with an open bottom which is closed with a refractory raw material in a container and sealed by a skirt member attached directly to the superstructure of the furnace which penetrates the refractory material. Track and elevation means permits the refractory filled loaded container to be pushed into position and lifted until it seals the furnace chamber and the refractory material is heated above its melting point to form a fused ingot. There- after, the fused ingot is lowered in the container onto the track means and pushed away while another container of raw material is pushed into position.
