Description

Technical Field

[0001] The utility model relates to the technical field of lost foam processing, in particular to a foam lost foam refractory coating drying room. Background Art

[0002] Lost foam casting is a type of full-mold casting using a foam plastic mold using binder-free dry sand combined with vacuum technology. It is mainly called "dry sand full-mold casting" or "negative pressure full-mold casting" in China, and is abbreviated as EPC casting. Lost foam casting is a new casting method in which foam models with similar size and shape to the casting are bonded together to form a model cluster. After being coated with refractory coating and dried, the cluster is buried in dry quartz sand and vibrated to shape. The mold is then poured under negative pressure, vaporizing the mold. Liquid metal then occupies the mold position and solidifies and cools to form a casting.

[0003] In order to improve the strength and fire resistance of the lost foam, a layer of refractory coating is usually applied to the surface of the model. This coating can prevent the penetration of molten metal and also helps the model maintain its shape at high temperatures. The drying room is a special facility used to dry the refractory coating applied on the surface of the foam model in the lost foam casting process.

[0004] In the actual working process, after the white mold is bonded, it is necessary to apply paint on the surface of the white mold. A special paint for lost foam is used, and the paint is applied three times. Each time the paint is applied, it is necessary to dry the paint.

In addition, the drying room is relatively hot and the environment is poor, which increases the risk of the working environment for personnel. Utility Model Content
