Abstract
Provided is a furnace mouth pouring block of an aluminum housing furnace. The furnace mouth pouring block is arranged on the upper portion of the aluminum housing furnace or on a lower furnace mouth and comprises an annular substrate formed by refractory mortar in a compressing and forming mode. An annular water cooling pipe is arranged in the annular substrate, and a water inlet and a water outlet of the water cooling pipe respectively extend out from the annular substrate. The furnace mouth is of an integrated structure in the compressing and forming mode, coefficients of thermal expansion of all parts are equal, thermal shock resistance is good, accordingly the problem that the furnace mouth is prone to expansion and cracking is avoided, service life of the furnace mouth is greatly prolonged, service life of the furnace is prolonged, and work efficiency of equipment is improved.
Description
Technical field
The utility model relates to a kind of aluminum hull stove, specifically a kind of fire door castable of aluminum hull stove.
Background technology
The aluminum hull stove is called aluminum hull intermediate frequency fusing circuit again, is a kind of electric smelter that utilizes the electromagnetic induction principle heating.Conventional aluminum hull stove fire door adopts asbestos board, furnace lining, converter nose to make up folded form of building layer by layer.Its structure is not an integral body, and various materials have thermal coefficient of expansion separately, causes furnace lining material to be easy to break, and service life is very short, has had a strong impact on the operating efficiency of equipment.
The utility model content
Technical problem to be solved in the utility model provides a kind of fire door castable of aluminum hull stove, has the integrative-structure good thermal shock, long service life.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of fire door castable of aluminum hull stove, the fire door castable is arranged on top or the bottom fire door of aluminum hull stove, the fire door castable comprises one by the annular matrix of refractory mortar injection-compression molding, be provided with the water cooling tube of annular in annular matrix, the water inlet of water cooling tube and delivery port stretch out in annular matrix respectively.
Be provided with converter nose at annular matrix, the outer rim of converter nose protrudes from annular matrix, and the inner edge of converter nose and the inner edge of annular matrix join.
The beneficial effects of the utility model are: fire door adopts the integral structure of injection-compression molding, the thermal coefficient of expansion equalization at each position, good thermal shock, thereby avoided the problem of easy swelling fracture, significantly increase the service life of fire door, prolonged furnace life, improved the operating efficiency of equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the set-up mode schematic diagram of converter nose.
Mark among the figure: 1, annular matrix, 2, water cooling tube, 3, water inlet, 4, delivery port, 5, converter nose.
The specific embodiment
Specify embodiment of the present utility model by reference to the accompanying drawings.
A kind of fire door castable of aluminum hull stove, the fire door castable is arranged on top or the bottom fire door of aluminum hull stove, the fire door castable comprises one by the annular matrix 1 of refractory mortar injection-compression molding, be provided with the water cooling tube 2 of annular in annular matrix 1, water inlet 3 and the delivery port 4 of water cooling tube 2 stretch out in annular matrix 1 respectively.Water cooling tube 2 in the annular matrix 1 can be an independent ring, also can be that a plurality of rings that distribute along same axis connect and compose.
In the used fire door castable of aluminum hull stove top fire door, annular matrix 1 is provided with converter nose 5, and the outer rim of converter nose 5 protrudes from annular matrix 1, and the inner edge of the inner edge of converter nose 5 and annular matrix 1 joins.
Adopt the fire door castable good thermal shock of refractory mortar one injection-compression molding, not easy to crack, reduce breakdown maintenance number of times and time, thereby improved the equipment operating efficiency.
