Abstract
The utility model is applicable to precision-investment casting directional solidification castings; Be specially adapted to the Slow cooling process after directional solidification castings is taken out from casting equipment.A kind of model casting directional solidification incubator, it is characterized in that, incubator is the cylindrical heat-preserving container of HGH3039 alloy, and alumina silicate needle punched blanket wraps heat-preserving container outer surface, the open and flat incubator bottom that is paved with of alumina silicate needle punched blanket, top alumina silicate needle punched blanket and metal drum are obturaged.During parcel alumina silicate needle punched blanket, use high temperature resistance pressure sensitive adhesive tape that the alumina silicate needle punched blanket of outer surface is cut out to upper, middle and lower three parts and tightly wrap and fix, wrap up altogether two-layer.This incubator bucket wall is without needle punched blanket, so metal cabinet is direct and high temperature casting mold heat-shift, but because of the double-deck needle punched blanket parcel in outside, make heat be stored in box house, reduce the cooling velocity of whole casing, its cylindrical structural, dispels the heat evenly formwork all over the body simultaneously, stablizes the inner grain growth of foundry goods and molten metal and solidifies.Also loss and the secondary pollution problem of needle punched blanket have been solved simultaneously.
Description
Technical field:
The present invention is applicable to precision-investment casting directional solidification castings; Be specially adapted to the Slow cooling process after directional solidification castings is taken out from casting equipment.
Background technology:
At present, when precision-investment casting directional solidification casting mold takes out from directional solidification casting mold chamber, conventionally need to be placed into and in incubator, carry out Slow cooling, the incubator of existing use is rectangle structure, conventionally alumina silicate needle punched blanket is laid on to the inner wall of HGH3039 alloy heat-preserving container, in high temperature casting mold after cast is positioned over, top covers alumina silicate needle punched blanket, the method is first because HGH3039 alloy is exposed in atmospheric environment, metal material self thermal conductivity is stronger, conduct heat very fast, the heat that inner shell reduces is after alumina silicate needle punched blanket conducts heat, by metal thermos barrel, absorbed rapidly and distribute, heat insulating ability is poor, because directional solidification crystallization chassis is generally circular configuration, the cylindrical distribution of the inner foundry goods of formwork, but the rectangle structure of incubator, can make formwork heat radiation inhomogeneous, casting mold localized cracks together.Secondly, due to the direct close contact alumina silicate of high-temperature mould needle punched blanket, can be scratched or damage, make it just to need for 5 to 7 days to change and reset, the needle punched blanket fine hair under long term high temperature is very easily cataclasm simultaneously, constantly dances in the air in operation.Not only reduce its service life, increase cost, secondary pollution works the mischief to operator's health simultaneously.
Summary of the invention:
Goal of the invention:
The object of this invention is to provide a kind of incubator that improves directional solidification casting mold heat-insulating property.
Technical scheme:
A model casting directional solidification incubator, incubator is the cylindrical heat-preserving container of HGH3039 alloy, alumina silicate needle punched blanket wraps heat-preserving container outer surface, the open and flat incubator bottom that is paved with of alumina silicate needle punched blanket, top alumina silicate needle punched blanket and metal drum are obturaged.
During parcel alumina silicate needle punched blanket, use high temperature resistance pressure sensitive adhesive tape that the alumina silicate needle punched blanket of outer surface is cut out to upper, middle and lower three parts and tightly wrap and fix, wrap up altogether two-layer.
Advantage of the present invention:
This incubator bucket wall is without needle punched blanket, so metal cabinet is direct and high temperature casting mold heat-shift, but because of the double-deck needle punched blanket parcel in outside, make heat be stored in box house, reduce the cooling velocity of whole casing, its cylindrical structural, dispels the heat evenly formwork all over the body simultaneously, stablizes the inner grain growth of foundry goods and molten metal and solidifies.Also loss and the secondary pollution problem of needle punched blanket have been solved simultaneously.The peripheral needle punched blanket of novel heat insulation case is changed once for average one month.
Accompanying drawing explanation:
Fig. 1 is the schematic diagram of existing heat-preserving container and laid inside needle punched blanket thereof;
Fig. 2 is novel heat insulating barrel and the outside schematic diagram of laying needle punched blanket thereof.
The specific embodiment:
A model casting directional solidification incubator, incubator is the cylindrical heat-preserving container of HGH3039 alloy, alumina silicate needle punched blanket wraps heat-preserving container outer surface, the open and flat incubator bottom that is paved with of alumina silicate needle punched blanket, top alumina silicate needle punched blanket and metal drum are obturaged.
During parcel alumina silicate needle punched blanket, use high temperature resistance pressure sensitive adhesive tape that the alumina silicate needle punched blanket of outer surface is cut out to upper, middle and lower three parts and tightly wrap and fix, wrap up altogether two-layer.
1, make the cylindrical heat-preserving container of HGH3039 alloy, determine its external height and diameter, be generally high 600mm, diameter 500mm.
2, the thick alumina silicate needle punched blanket of 6mm is tailored to the rectangle that is applicable to its height diameter, wrapped heat-preserving container outer surface, wrap up altogether two-layer.
3, use high temperature resistance pressure sensitive adhesive tape that its upper, middle and lower three parts are tightly wrapped and fixed, and top needle punched blanket and metal drum are obturaged.
4, use needle punched blanket by open and flat being paved with in incubator bottom.
Claims (2)
1. a model casting directional solidification incubator, it is characterized in that, incubator is the cylindrical heat-preserving container of HGH3039 alloy, and alumina silicate needle punched blanket wraps heat-preserving container outer surface, the open and flat incubator bottom that is paved with of alumina silicate needle punched blanket, top alumina silicate needle punched blanket and metal drum are obturaged.
2. a kind of model casting directional solidification incubator as claimed in claim 1, is characterized in that, during parcel alumina silicate needle punched blanket, uses high temperature resistance pressure sensitive adhesive tape that the alumina silicate needle punched blanket of outer surface is cut out to upper, middle and lower three parts and tightly wraps and fix, and wraps up altogether two-layer.
