Description
Technical field
The present invention relates to casting field more particularly to a kind of casting methods of churning driven mast.
Background technique
Boring mast work is one of important component of churning driven, and in the prior art, boring mast can be damaged using of long duration, and one
Denier bore mast be damaged to the destructiveness of churning driven be it is self-evident, security risk is caused to entire churning driven, and existing
The utilization rate for boring the casting chinese raw materials of mast is not high, the inadequate defect of structural strength.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides the casting method of churning driven mast, which is mentioned
The utilization rate of high steel improves casting accuracy, and structural strength is high, improving production efficiency, securely and reliably.
To achieve the goals above, the present invention proposes a kind of casting method of churning driven mast, the casting of the churning driven mast
Method includes the following steps:
S10: one layer of release agent coating release agent: is coated in the inner cavity of casting mould；
S20: it forms molten steel: weighing steel ingot raw material, and steel ingot raw material is heated to the molten steel of molten condition, and carry out
Keep the temperature 0.2~0.5h；
S30: heating mould: heating casting mould makes its temperature reach 1200~1400 DEG C, and keeps the temperature 0.3~0.6h；And
By the pouring molten steel in S30 in casting mould；
S40: casting: immediately pressurizeing to the casting mould under constant temperature from sprue gate after casting complete, added
Pressure is 0.015~0.02MPa, and pressing time keeps 1~1.5h；
S50: cooling: casting mould to be first cooled to 600~750 DEG C, constant temperature keeps 0.1~0.4h；Then by casting die
Tool is cooled to room temperature；
S60: demoulding: the brill mast demoulding of casting and forming is handled, and is machined out to be formed to it and is bored mast finished product.
Preferably, in step S20, steel ingot raw material is heated to the molten steel of molten condition, and carries out heat preservation 0.35h.
Preferably, in step s 30, casting mould is carried out being heated to 1300 DEG C, and keeps the temperature 0.45h.
Preferably, in step s 40, the plus-pressure is 0.0175MPa, pressing time 1.25h.
Preferably, in step s 50, casting mould is first cooled to 680 DEG C, constant temperature keeps 0.25h.
By adopting the above-described technical solution, the present invention has the advantage that the casting method improve steel utilization rate,
Casting accuracy is improved, structural strength is high, improving production efficiency, securely and reliably.
