Description
Technical field
The present invention relates to steel production cost fields, specifically, being a kind of magnesium titanium valve brick casting method.
Background technique
(casting) method of casting is that gold, silver are fused into liquid state, and the method that implements are made using the casting of model mould, it is
One of earliest gold and silver processing method.Casting is that medicine slurry after mixing is cast in engine shell body, and symbol is formed after solidification
Close the motor charge of design requirement.
Cast molding is also known as (static state) casting, is to make its solidification in the casting raw material note people's mold that will be ready for, obtains
Product similar with mold cavity.The raw material of cast molding can be monomer, the slurry through preliminary polymerization or polycondensation or polymerization
Object and the solution of monomer etc..Polymerization or polycondensation reaction usually occur in solidification process.In recent years, on traditional cast molding basis
On have also appeared some new casting methods, including inlay casting, centrifugal casting, curtain coating casting, slush moulding, rotational moulding etc..
Raw material of casting is typically all specific castable rather than the utilization to some scrap feed materials.
Summary of the invention
In order to solve the above-mentioned technical problem, the present invention discloses a kind of magnesium titanium valve brick casting methods, are crushed using magnesium titanium brick
Former casting material is replaced to correspondingly sized, reduces production cost.To achieve the goals above, the specific technical solution that the present invention uses
It is as follows:
A kind of magnesium titanium valve brick casting method, includes the following steps:
1) configuration casting liquid；Magnesium titanium brick after using is crushed to the graininess of grain of rice size, and auxiliary agent 1% is added；
2) filtering and deaeration；Deaeration is carried out inside deaeration machine after casting liquid is filtered；
3) cast molding；Alloy melt after deaeration is carried out refining treatment to be skimmed with mucking machine after twenty minutes, stands 30
Press-in die cast molding after minute, temperature are 700 DEG C, and the time is 6 minutes；
4) it hardens；Hardening by cooling 20 minutes；
5) demoulding；Remove mold；
6) it post-processes: carrying out except impurity, the post-processing such as purification.
Further improvement of the present invention, in step 1), magnesium titanium brick is used, magnesium titanium mass percent group in liquid of casting
As 1:5.
Further improvement of the present invention, inclined heated plate is 10 minutes in step 2.
Further improvement of the present invention, in step 1), auxiliary agent is according to quality proportioning are as follows: lucium 2%, graphene 5%,
Calcined kaolin 1%, sodium metasilicate 10%, remaining is water.
Further improvement of the present invention needs to carry out mold preheating 30 minutes before step 3) press-in die cast molding,
Mean temperature is 200 DEG C.
Further improvement of the present invention needs to cool down mold before step 5) demoulding, is cooled to 500 DEG C, when cooling
Between be 20 minutes.
Beneficial effects of the present invention: relative to existing casting method, the present invention uses the magnesium titanium brick after use to be crushed to phase
It answers size to replace former casting material, reduces production cost, secondary use is carried out to waste, it is energy saving, improve economic interests.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be described in further detail, the reality
It applies example for explaining only the invention, protection scope of the present invention is not constituted and limited.
Embodiment 1: a kind of magnesium titanium valve brick casting method includes the following steps:

3) cast molding；Alloy melt after deaeration is carried out refining treatment to be skimmed with mucking machine after twenty minutes, stands 30
Press-in die cast molding after minute, temperature are 700 DEG C, and the time is 6 minutes；
4) it hardens；Hardening by cooling 20 minutes；
5) demoulding；Remove mold；
6) it post-processes.It carries out except impurity, the post-processing such as purification.
In the present embodiment, in step 1), magnesium titanium brick is used in liquid of casting, and magnesium titanium mass percentage composition is 1:
5。
In the present embodiment, inclined heated plate is 10 minutes in step 2.
In the present embodiment, in step 1), auxiliary agent is according to quality proportioning are as follows: lucium 2%, graphene 5%, calcining are high
Ridge soil 1%, sodium metasilicate 10%, remaining is water.
In the present embodiment, need to carry out mold preheating 30 minutes, average temperature before the cast molding of step 3) press-in die
Degree is 200 DEG C.
In the present embodiment, it needs to cool down mold before step 5) demoulding, is cooled to 500 DEG C, cooling time 20
Minute.
Basic principles and main features and advantage of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe originals of the invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
