Pressurized with compressed air rise liquid mold, with after emit.Air discharge abandons as not having " cost ", the most not
So, it is electrical heat energy that pressure release gas carries heat, abandons steam equal to abandoning electric energy, cost of idleness undoubtedly.
Certainly, current holding furnace cost of idleness is not only to abandon a steam, and the waste of maximum is electricity
Thermal element baking radiation liquid aluminum, the thermal efficiency is low, and liquid aluminum temperature is high, and aluminum liquid oxidation is serious, it is not intended to justice
Loss waste electric energy also consumes aluminum liquid, and its aluminum liquid lost value is not less than heating power consumption cost；Also produce a large amount of
The additional arduous labor much skimmed of oxidizing slag.The particularly insulation of stove needs heating high-power heating time the best,
Causing liquid aluminum temperature near pyrogen part too high, oxidizing slag is a lot, and i.e. many consuming electric energy reduce again metal and receive
Rate, loses big for cast aluminium No.1 cost killer.
Technical standpoint is analyzed, and the oxidation more than 850 DEG C of hydrothermal solution surface temperature is substantially accelerated, and 850 DEG C is that oxidation rate is steep
Rise flex point, if temperature of aluminum liquid less than 750 DEG C, heating source temperature at about 850 DEG C, the temperature of only 100 DEG C
Difference heating such as Numerical heat transfer amount, numerical value is the most limited, and even heat output is less than heat dissipation capacity.So, improve
The temperature of low temperature aluminium liquid, is only improved the radiation temperature of thermal source to strengthen heat output, and the radiation temperature of thermal source is high
Amount of oxidation nature equal proportion increases, and working laboriously of only having no way out is skimmed, the many losses again of many power consumption expenses
Aluminum liquid, several years temperature how cost！
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 internal layer cracks burner hearth, and aluminum liquid passes through crackle and oozes
Thoroughly invade heat-insulation layer material hole, make the insulation material of stove lose heat-insulating property.Current stove, insulation is not
It is insulation material and the effect of insulation construction generation, is mainly the heating by heating and maintains temperature.
Also bringing the liquid aluminum temperature near electrothermal part too high, oxidizing slag is a lot, can not avoid.
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.The baking that heats up the most slowly also has water droplet for 10 days and goes out,
The temperature difference of visible stove ectonexine is big, and the slow material thermal resistance that in fact heats up again still exists, the temperature ladder of ectonexine
Degree difference will not be because of the disappearance that heats up slowly.So, the burner hearth chamber cracking of integrated poured molding is difficult to avoid that in theory.
In order to save electricity, reduce labor intensity, raising recovery rate of iron, cost to be reduced just needs
Have and do not aoxidize few aluminium oxide liquid, do not lose exhausting heat energy, be rapidly heated and the casting of wheel hub that burner hearth chamber is not split is protected
Temperature stove.
