A kind of rectangular aluminum liquid holding furnace that is suitable for casting and rolling process, include furnace binding, body of heater, fire door, combustion system, smoke evacuation system and electric control system is characterized in that: the slag line of its body of heater is following adopts not sticking aluminium castable integrated poured with aluminium liquid contact portion, furnace roof adopts hanger brick cast flat-tope structure, and fire door adopts the electric up-down mode.
Described fire door is provided with two.
The angle of skimming of the stove gate of described fire door inboard is 25 °.
Described combustion system adopts four burners, and they are divided into two pairs of two ends that are arranged on body of heater.
The below of described body of heater one side burner is provided with the dewatering outlet, and this wing furnace body sidewall is provided with the temperature measuring equipment that is between burner and dewatering outlet.
The beneficial effects of the utility model have:
Foreign side interior angle circle, good looking appearance, is suitable for the requirement of large-tonnage casting and rolling process at rational in infrastructure, anti-clinkering property, high insulating effect, and aluminium liquid quality is good, not slagging scorification, body of heater long service life.
Description of drawings
Fig. 1 is the cross-sectional view of facing of the present utility model.
Fig. 2 is the cross-sectional view of overlooking of the present utility model.
Fig. 3 is that cross-sectional view is looked on a left side of the present utility model.
In accompanying drawing, 1, integral furnace bottom; 2, hard calcium silicate board; 3, insulating brick; 4, furnace bottom antiseepage castable; 5, not sticking aluminium castable; 6, dewatering outlet; 7, burn right device; 8, burner dedicated pouring material; 9, furnace roof castable; 10, hanger brick; 11, hanging hook; 12, furnace roof crossbeam; 13, pressure sensor; 14, furnace temperature thermocouple; 15, furnace shell steel structure; 16, anchoring hook; 17, steel fiber castable; 18, exhaust opening; 19, skimming gate A; 20, skimming gate B; 21, aluminium liquid temperature thermocouple.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As Figure 1-3, furnace binding of the present utility model includes integral furnace bottom 1, furnace shell steel structure 15 and furnace roof crossbeam 12.Integral furnace bottom 1 and furnace shell steel structure 15 are welded by the thick steel plate of 10mm (Q235-A) and shaped steel, and better mechanism intensity is arranged, and reinforce steel construction with anti-deformation at key position.Integral furnace bottom 1 adopts 10MM steel plate and No. 20 channel-section steels to be spliced, and better mechanism intensity is arranged.Furnace roof crossbeam 12 is comprised of No. 25 I-steel, is densely covered with No. 10 channel-section steels and No. 10 I-steel, and in order to the hanging hook 11 that top hanging brick 10 and metal are installed, hanging hook 11 is evenly arranged every 300mm, and hanger brick 10 is fixed on furnace roof crossbeam 12.Furnace roof adopts the flat-tope structure can the enhanced rad effect, improves the effect fuel availability, energy savings, and sound construction, the life-span is long.
Polycrystalline substance of the present utility model is that integral furnace bottom 1 top is hard calcium silicate board 2, insulating brick 3, furnace bottom antiseepage castable 4 and sticking aluminium castable 5 successively.The molten bath part adopts the not sticking integrated poured construction of aluminium castable 5, can effectively prevent the bonding phenomenon of aluminium and furnace lining, internal layer is built by laying bricks or stones by the castable of impervious aluminium and insulating brick and is formed, during construction, piecemeal is poured into a mould with advancing, be provided with spill wedge mouth between piece and piece, change and anti-aluminium liquid seepage to adapt to expand with heat and contract with cold, also have simultaneously fabulous heat insulation effect.Side wall more than metal line 300mm is by tonerde brick (or three grades of high-alumina bricks), and light-weight insulating brick and ceramic fiber blanket form, and the top is comprised of quality refractory concrete, ceramic fiber blanket, light thermal-shield refractory concrete.With the heat resisting steel clip, hanger brick is fixed on furnace roof shaped steel all arranging uniformly every stove 300mm on furnace roof.
