Existing holding furnace, the most suitable furnace temperature 700-800 DEG C of temperature of pressure release aerofluxus, it is usually at present with compression Air pressurized rise liquid mold, with after emit.Air discharge abandons as not having " cost ", and actually this is not so, It is electrical heat energy that pressure release gas carries heat, abandons steam equal to abandoning electric energy, cost of idleness beyond doubt.

Certainly, current holding furnace cost of idleness is not only also to abandon a steam, and the waste of maximum is Aluminum liquid oxidation is serious, and its aluminum liquid lost value is not less than heating power consumption cost, produces a large amount of oxidizing slag additional very The arduous labor skimmed more.The particularly insulation of stove needs heating high-power heating time the best, cause pyrogen part Neighbouring liquid aluminum temperature is too high, and oxidizing slag is a lot, and i.e. electric energy that expend reduce again recovery rate of iron more, lose it It is greatly cast aluminium cost killer.

Also can not be optimistic be the common fault being incubated the most integrated poured the best burner hearth, reason is due to burner hearth The thermograde of refractory material ectonexine is poor, produces internal layer inconsistent with the flatulence of heat type yardstick of outer layer, the temperature of internal layer Degree highly expanded yardstick is big, and the temperature low bulk yardstick of outer layer is little, and the bigger swell increment of internal layer is burst and split overall burner hearth, Aluminum liquid passes through crackle infiltration and invades heat-insulation layer material hole, makes the insulation material of stove lose heat-insulating property.At present Stove, insulation is not the effect that insulation material and insulation construction produce, mainly adding by heating Heat maintains temperature.Obviously electric energy is wasted.

In order to avoid burner hearth material cracks, new stove is reached the standard grade and is used extremely slow heating curve (more than 10 day), dries The roasting time is the longest, and waste adds thermoelectric power in a large number, and the slow material thermal resistance that in fact heats up again the most still exists, ectonexine Thermograde difference will not be because of the disappearance that heats up slowly, on the burner hearth chamber Cracking Theory of integrated poured molding, difficulty is avoided, In fact the baking integrated poured burner hearth of 10 days also has water droplet to go out, it is seen that in stove, the outer temperature difference of stove is big.

For power saving, laborsaving, raising recovery rate of iron, low-cost production, it is desirable to have a kind of door can embed door Stove in mouthful hole, do not lose the stove of the stove of exhausting heat energy, not aluminium oxide liquid, do not ftracture in the burner hearth chamber that is rapidly heated Wheel hub casting furnace.
