Abstract

The invention relates to devices for smelting furnaces of non-ferrous metallurgy and can be used in the repair of refractory slabs. The goal is to reduce the repair time and reduce costs by eliminating the dismantling and installation of the caissons. The furnace contains caisson walls 1 mounted on a refractory floor 2, arch 3. The furnace frame consists of racks 4 connected by transverse beams 5 and longitudinal beams 6 connecting the upper ends of the racks 4. Brackets 7 freely support the longitudinal beams 6 bolted to the frame of the walls 1. The invention makes it possible to shorten just the furnace when replacing the refractory masonry. 1 il.

The invention relates to non-ferrous metallurgy, in particular, to smelting furnace devices, and can be used in the repair of refractory slabs of hearths, for example, furnaces for continuous smelting of concentrates in a liquid bath.

The purpose of the invention is to reduce the repair time and reduce costs by eliminating dismantling and. mounting caissons.

The drawing shows a furnace for melting in a liquid bath, a cross-section.

The furnace includes caisson walls 1 mounted on the refractory along the cross (walls) of the bottom 2 and roof 3. The frame consists of vertical posts 4 connected in pairs by transverse beams 5 and the supporting vertical posts 4 supporting the weight of the walls and roof to the furnace frame , freeing the laying of the hearth from the load. In the case when it is necessary to replace a worn floor, it is dismantled, and the walls and arch remain suspended on the frame.

The invention makes it possible to shorten just the furnace when replacing the refractory masonry of the hearth, since it eliminates the need to dismantle the caissons.

Invention Formula The smelting furnace contains, and the roof, the refractory hearth, the caisson walls, part of the beams 6 connecting the upper ends of the 5 frame, consisting of vertical columns, struts 4. The longitudinal beams 6 are connected by transverse beams, and the complexator of thermal expansion of the refractory masonry of the bottom and walls, characterized in that Brackets 7, fastened bolted to the frames of the caissons 1. During the heating of the furnace when the walls expand, the brackets 7, rigidly connect the repair and reduce costs due to the coffered walls 1, prevent the removal and installation of caissons, glides along the surface of the longitudinal girders of the coffered walls were made; 6, to compensate for the expansion of the water-cooling in the form of support brackets, one resting on vertical pillars 4, the weight of the walls and roof is transferred to the furnace frame, freeing the floor masonry from the load. In the case when it is necessary to replace a worn floor, it is dismantled, and the walls and arch remain suspended on the frame. The invention makes it possible to shorten just the furnace when replacing the refractory masonry of the hearth, since it eliminates the need to dismantle the caissons. Invention Formula so that, in order to reduce the repair time and reduce costs by eliminating the dismantling and installation of caissons, myh walls. At the same time thanks to the support of crown-. the end is rigidly connected new matte 7 to beams 6, in turn, 25 longitudinal framework beams. the end of rigidly connected with the frames of the caissons, the other freely resting on the longitudinal beams of the frame.
