Abstract

The invention discloses a casting forming method using aluminum ash for replacing a riser exothermic compound. According to the casting forming method, melted iron is poured into a casting mold to be cooled and solidified, and the aluminum ash is added in the process of pouring the melted iron. As the aluminum ash is added in the process of pouring the melted iron, and the principle of aluminum ash spontaneous combustion is used for heating, the cooling speed of the melted iron can be reduced, the cavity phenomenon in a casting is eradicated, and the yield is increased; for the electrolytic aluminum industry, the aluminum ash to be discarded is aroused to emit heat, the cost is almost zero, the loss can be greatly reduced, the casting forming method is beneficial to environmental protection, and therefore the enterprise competitiveness is improved.

Description

A kind of aluminium ash substitutes the foundry goods forming method of riser compound
Technical field
The present invention relates to a kind of electrolytic aluminium field, particularly relate to a kind of foundry goods forming method.
Background technology
The processing method of present foundry goods is all naturally cool after molten iron being poured into mould.After foundry goods is shaping, find that cast-internal has cavity, yield rate is too low.Technical staff runs into this problem and have passed through prolonged and repeated research, and final discovery is poured in process at molten iron, and cast(ing) surface cooling is too fast, and rising head shrinkage cavity is serious, thus result in cast-internal and have cavity.
After having found the problems referred to above, take various ways and solve this problem, but effect is always undesirable, such as: we have purchased exothermic mixture and fall apart to rising head surface, thus ensure the temperature of rising head, although also can relatively reduce shrinkage cavity phenomenon, become native language high, add exothermic mixture 5 kilograms at every turn, cost increases by 25 yuan, this considerably increases cost for aluminium electrolysis enterprise, this reduces the competitiveness of enterprise.
Summary of the invention
The object of this invention is to provide a kind of cost low, and improve the foundry goods forming method of casting yield.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of foundry goods forming method, pours cooled and solidified in casting die into, adds aluminium ash in the process pouring molten iron into by molten iron.
Preferably, described aluminium ash quality is 1 ~ 2.5kg.
Preferably, described aluminium ash quality is 2kg.
Preferably, after adding aluminium ash, by the rising head cap covers of casting die.
Preferably, described lid is iron covering, is provided with heat-insulation layer at the nexine of lid.
Relative to prior art, add aluminium ash in the process that the present invention pours at molten iron, utilize the principle of aluminium ash spontaneous combustion to generate heat, thus the water-cooled speed of iron can be slowed down, stop the generation of cast-internal cavitation, improve yield rate, and aluminium ash is for aluminum electrolysis industry, aluminium ash inherently to be discarded wakes up with a start heating, cost is almost nil, loss can be saved widely, and be conducive to environmental protection, thus improve enterprise competitiveness.
Detailed description of the invention
A kind of foundry goods forming method, pours cooled and solidified in casting die into, adds aluminium ash in the process pouring molten iron into by molten iron, described aluminium ash quality is 1 ~ 2.5kg, and for stopping cast-internal cavitation, aluminium ash quality is most preferably taken as 2 kg.
After adding aluminium ash, by the rising head cap covers of casting die, for insulation; Lid is iron covering, is provided with heat-insulation layer at the nexine of lid.
Principle of the present invention is: add aluminium ash in the process that the present invention pours at molten iron, the principle of aluminium ash spontaneous combustion is utilized to generate heat, thus the water-cooled speed of iron can be slowed down, stop the generation of cast-internal cavitation, improve yield rate, and aluminium ash is for aluminum electrolysis industry, aluminium ash inherently to be discarded wakes up with a start heating, and cost is almost nil, can save loss widely, and be conducive to environmental protection, thus improve enterprise competitiveness.
