Description

The anti-swell support meanss of large-scale wind driven generator base casting

Technical field

It the utility model is related to casting technique equipment technical field, more particularly to a kind of large-scale wind driven generator base casting Anti- swell support meanss.

Background technology

It is well known that sand casting is that the casting method of casting is produced in sand mold, it is that one in casting industry is excellent Technology, its application is very extensive.Steel, iron and most of non-ferrous alloy castings can all be obtained with sand mould casting method.By Cheap and easy to get in the Modeling Material used in sand casting, Casting mold manufacturing is easy, single-piece production to casting, produces by batch and largely Production adapts to, and is always the basic technology in Foundry Production for a long time.

However, when being cast especially for heavy castings as large-scale wind driven generator base casting, easily cause sandbox Dilatancy；Such as：Wind power casting size is larger, high (such as the high 4m casting static pressure pressure head of static pressure pressure head in cast Up to 270KPa.)；Meanwhile wind power casting material is spheroidal graphite cast-iron, its graphitization expansion pressure is up in process of setting 3MPa。

Sandbox is mostly steel structure sand box used by wind power casting at present, it is difficult to bears so high pressure.Cast and Casting solidification process cheek can make a concession deformation, produce " swell " phenomenon, cause casting to be deformed, shrinkage porosite situations such as, seriously When casting can be caused to scrap, bring about great losses to Foundry Works (as shown in figure 1, the above-mentioned Fig. 1 direction of arrow is sandbox expansion The direction of deformation).

To sum up, how when implementing large-scale wind driven generator base cast casting the yielding above-mentioned skill of traditional sandbox is overcome Art defect is the technical problem that those skilled in the art are badly in need of solving.
