Abstract

The invention provides a casting process using an evanescent mode, belonging to the field of the casting process. The evanescent mode is coated with paint; and the evanescent mode comprises a refractory aggregate, a bonding agent and a suspension agent and further comprises 0.2-0.95% of organic short fibers, particularly 0.35-0.45% of the organic short fibers. The casting process using the evanescent mode has the beneficial effects that a product cast by the evanescent mode coated with the paint has the characteristics of smooth and clean surface, dense inner organization, no air pores and high quality product rate.

Description

A kind of casting technique of utilizing the disappearance mould
Technical fieldThe present invention relates to a kind of casting technique of utilizing the disappearance mould, belong to the casting technique field.
Background technologyCasting method with the vanishing pattern is also claimed cavityless casting; Normally will be embedded in by the disappearance model that the foamed polystyrene body forms in the sand mold; The casting motlten metal is disappeared the gasification of disappearance model by the heat of motlten metal, in the space that produces, fills motlten metal simultaneously; Make the casting method of casting finished product, this method is widely used in the making of diel.Lost foam paint is very big to the casting quality influence, and many casting defects such as pore, scab etc. are all closely related with coating, produce a large amount of liquid state and gaseous products like disappearance mould pyrolysis in the casting cycle; Must be discharged in the molding sand through coating, otherwise can make cast(ing) surface produce defective, and simply increase the coating gas permeability; Can influence other performances of coating again, cause scab like meeting, cast(ing) surface is not bright and clean; Rugosity is big, and the difficult removing of scab; If the coating gas permeability is low, can brings again to be unfavorable for the discharge of mould pyrolysis gas that disappears because of gas permeability is bad, and bring defective to foundry goods.
Summary of the inventionDefective in view of prior art exists the purpose of this invention is to provide a kind of casting technique of utilizing the disappearance mould.
For realizing above-mentioned purpose; The technical solution that the present invention adopted is: a kind of casting technique of utilizing the disappearance mould, and said disappearance mould scribbles coating, in coating is formed, introduces organic short fiber; Thereby coating is gasified when the casting heating status prior to the disappearance mould; Thereby on dope layer, leave steam vent, reserve passage, overcome the defective of gas permeability difference for the disappearance parting line venting of the gasification that lags behind; Include refractory aggregate, binding agent and suspending agent in this lost foam paint, it is characterized in that: also comprise the organic short fiber of 0.2%-0.95% in the said coating, especially comprise the organic short fiber of 0.35%-0.45%.
A kind of casting technique of utilizing the disappearance mould, its beneficial effect is: utilize the product of the lost foam casting that has this coating, have any surface finish, dense internal organization, pore-free, the characteristics that the percentage of A-class goods is high.
The specific embodiment
A kind of casting technique of utilizing the disappearance mould; Said disappearance mould scribbles coating; In coating is formed, introduce organic short fiber, thereby coating is gasified prior to the disappearance mould when the casting heating status, thereby on dope layer, leave steam vent; Reserve passage for the disappearance parting line venting of the gasification that lags behind, overcome the defective of gas permeability difference; Include refractory aggregate, binding agent and suspending agent in this lost foam paint, it is characterized in that: also comprise the organic short fiber of 0.2%-0.95% in the said coating, especially comprise the organic short fiber of 0.35%-0.45%.

Claims (1)

1. casting technique of utilizing the disappearance mould, said disappearance mould scribbles coating, includes refractory aggregate, binding agent and suspending agent in the coating; It is characterized in that: also comprise the organic short fiber of 0.2%-0.95% in the said coating, especially comprise the organic short fiber of 0.35%-0.45%.
