Manufaturing method of hydraulic pressure casting using with compacted vermicular cast iron and compound

摘要

The present invention relates to a method for manufacturing a hydraulic pressure casting product to which CV graphite cast iron and a CV spheroidizing agent are applied. Moreover, the method for manufacturing a hydraulic pressure casting product, which is capable of manufacturing a product for hydraulic pressure casting using compacted vermicular (CV) graphite cast iron, comprises: a melting step of preparing and melting predetermined raw materials and subsidiary materials, and accompanying spheroidizing treatment after tapping; a molding step of preparing and mixing predetermined raw materials, and manufacturing a mold through molding and combining; a core preparing step of preparing a core; an injecting step of manufacturing and inserting a core mold; a demolding step of cooling a product demolded after cooling after molten metal having gone through the melting step is injected into the mold manufactured through the molding step; a post-treating step of performing removal, shot, and a finish process of the product having gone through the demolding step; and an inspection package shipping step of shipping after final inspection of the dimension and appearance of the post-treated product and packaging.
