FIRE-BRICK PANEL.
Application filed November 10, 1924. Serial No. 749,109.
To all 20720221. 2'25 may concern:
Be it known that l, JEAN RENE CHARLES Francois Xavrnn Rnrnnn, a citizen of the French Republic, residing at 53 Rue de Chateaudun, Paris, France, have invented certain new and useful improvements in Fire-Brick Panels, of which the following specification.
For the manufacture of doors, covers, dampers or arches of furnaces, panel's lined with fire brick are in current use which coniprise a backing plate provided with flanges between which the bricks are held in close contact and are thus aroperly maintained. But such panels are heavy and cannot be cooled in an approved manner owing to the presence of the backing plate, and they are iarticularly subject to a great drawback from the fact that the falling of a single brick will cause the deterioration of the entire lining.
According to the present invention, the fire bricks are maintained either individually or in groups by means of a metallic frame without backing which comprises two sets of rectangular ribs adapted to exercise a pressure upon the lateral faces of the bricks.
In the manufacture of such panels, I employ a process wherein the bricks are disposed in a mould, allowing free spaces for casting the said frame and ribs; the bricks are thus surrounded by metal for the whole or a part of their height, and due to the shrinkage of the metal when solidifying, the bricks are strongly held in place and compressed.
The height and thickness of the bricks and the thickness of the metallic frame ant ribs are determined in accordance with the dimensions and use of the panel, and in particular, the height of the bricks and the thickness of the ribs may be reduced to a minimum, in view of the rigid construction of the brick and rib aggregate.
The metal preferably used in casting such pieces is cast steel, but obviously I may employ cast iron or any other suitable metal or alloy. For the brick I may use any suitable fire brick based upon or containing alumina, silica, chromium, magnesia or the like.
Such panels have the maximum li htness, the bricks are held in the most approved manner, and the cooling of the bricks as well as of the frame and ribs is properly ensured since tle outer surface of all the pieces is in contact with the air.
Two constructional forms of panel in ac- I cordance with the invention are described hereunder by way of example, with reference to the appended drawings.
Figs. 1 and 2 show respectively a vertical front elevation and a cross section of a door for open hearth furnaces.
Figs. 3 and ishow respectively av cros section and a bottom plan view of a cover for furnaces of the Pits type (preliminary heating or reheating for ingots).
The door for open hearth furnaces (Figs. 1 and consists of a main frame 1 which is integral with the vertical ribs 2 and the horizontal ribs 3 forming a grid, and the fire brick pieces 4 are disposed in the spaces of the same. Each space may contain a single brick or a small group of bricks. The said main frame and the ribs 2, 3 integral therewith are formed by casting a suitable metal in a mould in which the bricks 4 have been preliminarily placed, leaving between the several bricks and also between the latter and the sides of the mould the necessary spaces for casting the frame and the ribs.
The bricks themselves are suitably recessed to rece've the frame and ribs in such manner as to offer a substantial construction for the whole device; the bricks i form a continuous surface upon the inner side of the door, the latter being provided as usual with the loops 5 engaging the hooks, not shown, disposed on the vertical wall of the furnace 6.
In Figs. 3 and the cover for the Pits furnace consists of a flanged main frame 7, and within the said frame the longitudinal ribs 8 and the transverse ribs 9 constitute a grid. In the spaces of the grid are disposed the fire brick pieces 10, either singly or in small groups.
The main frame 7 and the integral ribs 8, 9 are formed by casting a suitable metal in a mould in which are preliminarily disposed the bricks 10, allowing suitable spaces between the several bricks and between the latter and the mould for casting the frame and the rise. The sides of the frame extend for some distance above the arched portion and suitable loops are secured to the groups comprising a small number of tire flange of the frame which co-operate with bricks secured in the openings of said lattice 10 lifting devices for the removal and replac- Work, the inner and outer sides of said ing of the furnace door. groups being free.
