Abstract
A kind of to solve because of the method for section's alloy-steel casting face crack like this, the present invention relates to casting manufacturing technology fields；Its operating procedure is as follows：It is poured into a mould according to custom requirements, determines that placing temperature is 1,400 1500 DEG C according to factors such as casting section thicknesses；It is measured by MAGMA simulation softwards and scene temperature and determines soaking time, ensure that molten steel solidifies completely in casting mold；According to determining soaking time shake out sand removal, entire sand removal process requires to complete in 10 40min according to casting size and wall thickness difference；One piece of draughty vacant lot of advance reservation is used to place casting；The casting cleared up is placed on natural cooling on vacant lot.The generation of cast(ing) surface crackle can be solved, guarantee is provided, while greatly reduce production cycle and production cost to product quality, good economic benefit is created to factory.
Description
Technical field
The present invention relates to casting manufacturing technology fields, and in particular to a kind of to solve because of section's alloy-steel casting face crack like this
Method.
Background technology
It is existing that because of section, like this in sand mold inside holding to certain temperature, then the common production technology of alloy-steel casting is after cast
Lift carries out sand removal, removal dead head, then is managed into furnace treatment.Such scheme drawback is to generate in casting cooling procedure
Harmful brittlement phase, leads to the generation of cast(ing) surface crackle, while this material solderability is poor, and it is big to lead to reprocess difficulty, waste product
Rate is high, and production cost is high, it would be highly desirable to improve.
Invention content
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of simple in structure, reasonable design makes
It solves, because of the method for section's alloy-steel casting face crack like this, the generation of cast(ing) surface crackle can be solved, give product matter with convenient
Amount provides guarantee, while greatly reduce production cycle and production cost, and good economic benefit is created to factory.
To achieve the above object, the technical solution adopted by the present invention is：Its operating procedure is as follows：
1st, it is poured into a mould according to custom requirements, determines that placing temperature is 1400-1500 DEG C according to factors such as casting section thicknesses；
2nd, it is measured by MAGMA simulation softwards and scene temperature and determines soaking time, ensure that molten steel solidifies completely in casting mold；
3rd, according to determining soaking time shake out sand removal, entire sand removal process is required according to casting size and wall thickness difference in 10-
It is completed in 40min；
4th, one piece of draughty vacant lot of advance reservation is used to place casting；
5th, the casting cleared up is placed on natural cooling on vacant lot.
Further, the soaking time in the step 2 is 0.5-7h, and holding temperature is kept the temperature when being 1400-800 DEG C
0.5-3h, holding temperature keep the temperature 2-4h when being 800-300 DEG C.
After above-mentioned technique, the present invention has the beneficial effect that：It is of the present invention a kind of to solve because of section's alloy-steel casting like this
The method of face crack can solve the generation of cast(ing) surface crackle, and guarantee is provided, while greatly reduce life to product quality
Period and production cost are produced, good economic benefit is created to factory, the present invention has simple in structure, and setting is reasonable, makes
The advantages that at low cost.
Description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also
To obtain other attached drawings according to these attached drawings.
Fig. 1 is the parametric data table of embodiment one and embodiment two.
Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
Referring to as shown in Figure 1, present embodiment（Embodiment one）The technical solution adopted is that：Its operating procedure is such as
Under：
1st, it is poured into a mould according to custom requirements, determines that placing temperature is 1450 DEG C according to factors such as casting section thicknesses；
2nd, it is measured by MAGMA simulation softwards and scene temperature and determines soaking time, ensure that molten steel solidifies completely in casting mold；
3rd, according to determining soaking time shake out sand removal, entire sand removal process exists according to casting size and the requirement of wall thickness difference
It is completed in 15min；
4th, one piece of draughty vacant lot of advance reservation is used to place casting；
5th, the casting cleared up is placed on natural cooling on vacant lot.
Further, the soaking time in the step 2 is 4.5h, and holding temperature keeps the temperature 0.5h when being 1000 DEG C, protects
Temperature keeps the temperature 3h when being 300 DEG C.
After above-mentioned technique, present embodiment has the beneficial effect that：A kind of solution described in present embodiment
Because of the method for section's alloy-steel casting face crack like this, the generation of cast(ing) surface crackle can be solved, guarantee is provided to product quality,
Production cycle and production cost are greatly reduced simultaneously, creates good economic benefit to factory, the present invention has structure letter
The advantages that list, setting is reasonable, low manufacture cost.
Embodiment two：
The present embodiment the technical solution adopted is that：Its operating procedure is as follows：
1st, it is poured into a mould according to custom requirements, determines that placing temperature is 1500 DEG C according to factors such as casting section thicknesses；
2nd, it is measured by MAGMA simulation softwards and scene temperature and determines soaking time, ensure that molten steel solidifies completely in casting mold；
3rd, according to determining soaking time shake out sand removal, entire sand removal process exists according to casting size and the requirement of wall thickness difference
It is completed in 40min；
4th, one piece of draughty vacant lot of advance reservation is used to place casting；
5th, the casting cleared up is placed on natural cooling on vacant lot.
Further, the soaking time in the step 2 is 6h, and holding temperature keeps the temperature 1h, heat preservation temperature when being 1200 DEG C
It spends and keeps the temperature 5h when being 400 DEG C.
Embodiment one is identical with the size of two casting of embodiment, and material is CW6MC.
The above is merely illustrative of the technical solution of the present invention and unrestricted, and those of ordinary skill in the art are to this hair
The other modifications or equivalent replacement that bright technical solution is made, without departing from the spirit and scope of technical solution of the present invention,
