Abstract
The invention relates to a casting method for improving metal liquid quality, which comprises the following steps: using overlay film sand to prepare a sprue cup seat cooperated with the bottom of the sprue cup; forming a new sprue cup by combining the sprue cup seat, a filter screen and the sprue cup in order; placing the new sprue cup on a sprue used by a lost foam casting technology; and casting the metal liquid in the sprue cup. When casting is carried out by the method, impurity in the metal liquid can be filtered through the filter screen, integral quality of the casting is improved, and casting yield is greatly increased.
Description
Technical field
The present invention relates to a kind of lost foam casting process, be specifically related to a kind of pouring procedure improving metal liquid quality.
Background technology
At present, a cup is all needed when adopting existing lost foam process to produce foundry goods, traditional preparation method directly in cup, topples over molten metal, but owing to often there is various impurity in molten iron, once impurity enters foundry goods together in company with molten metal, usually cause the mass defect of foundry goods, cause waste product, therefore provide a kind of pouring procedure improving metal liquid quality significant.
Summary of the invention
The object of this invention is to provide a kind of pouring procedure improving metal liquid quality.
To achieve these goals, the technical solution of employing is in the present invention:
Improve a pouring procedure for metal liquid quality, comprise the following steps:
(1) adopt precoated sand prepare one with the cast gate cup matched bottom cup;
(2) cast gate cup, screen pack, cup are combined successively the new cup of formation;
(3) new cup is placed on lost foam casting process sprue used;
(4) to casting of molten metal in cup.
In described step (2), cast gate cup, screen pack, cup are by combining from top to bottom, and blend compounds coagulates agent to be fixed.
The beneficial effect that the present invention can produce: adopt the method to pour into a mould, by the impurity in molten metal by screen pack filtering, can improve the total quality of foundry goods, substantially increases the yield rate of foundry goods.
Detailed description of the invention
Improve a pouring procedure for metal liquid quality, comprise the following steps:
(1) adopt precoated sand prepare one with the cast gate cup matched bottom cup;
(2) cast gate cup, screen pack, cup are combined successively the new cup of formation;
(3) new cup is placed on lost foam casting process sprue used;
(4) to casting of molten metal in cup.
In described step (2), cast gate cup, screen pack, cup are by combining from top to bottom, and blend compounds coagulates agent to be fixed.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned citing, and the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
Claims (2)
1. improve a pouring procedure for metal liquid quality, it is characterized in that, comprise the following steps:
(1) adopt precoated sand prepare one with the cast gate cup matched bottom cup;
(2) cast gate cup, screen pack, cup are combined successively the new cup of formation;
(3) new cup is placed on lost foam casting process sprue used;
(4) to casting of molten metal in cup.
2. a kind of pouring procedure improving metal liquid quality according to claim 1, is characterized in that, in described step (2), cast gate cup, screen pack, cup are by combining from top to bottom, and blend compounds coagulates agent to be fixed.
