Abstract:
1. A method for constructing a furnace for the manufacture of glass, with refractory concrete, to obtain a monolithic unit by manufacturing, distributing and installing temporary structures and filling them with concrete refractory for the furnace construction, the furnace is of the type that comprises: furnace sections that perform specific functions of melting and refining, which are built on a structure of basal support constituted by a robust slab placed directly on a support system, as well as an assembly of columns, beams, floor systems and lateral restriction elements or bracing forming the peripheral support structure of the furnace where the robust slab wall is made with hydraulic concrete made from reinforced cement, the furnace being manufactured by: forming a first temporary structure to walls of a first section of the furnace; filling the first temporary structure with a refractory concrete, to the formation of monolithic walls corresponding to the first section of the furnace; removing the first temporary structure of the monolithic wall of the first section of the furnace once the concrete refractory has hardened; and forming subsequent temporary structures corresponding to vaults and floors once the concrete refractory has hardened from a preceding section of the furnace, forming a monolithic unit for each section of the furnace, said furnace sections including regenerative chambers with side walls, a front wall, a back wall, an intermediate wall, a vault, a floor and ports; a melter that includes a cup, side walls, a front wall, a back wall, a vault and a floor; a throat and a refiner that include a cup, a vault and a floor; and tunnels into a chimney, completely constructed of refractory concrete, characterized by: constructing each wall temporary structure with a pair of parallel side plates and a pair of outer plates, which close the side plates, forming an internal hollow space between the same, whose internal surfaces are in contact with the refractory concrete; supporting the plates by a layer of crossbars, to provide rigidity to the plates; reinforcing the crossbars layer with bars placed outside the crossbar; bracing the plates to attach the temporary structure wall; filling the inside cavity delimited by the plates with refractory concrete; removing the temporary structure once the concrete refractory has hardened; and pouring the plate refractory concrete floor delimited by walls.
