Abstract

The invention discloses dry forsterite sand for full-mould casting and a preparation method for the dry forsterite sand. The dry forsterite sand is prepared from the following raw materials in part by weight: 80 to 96 parts of forsterite sand, 2 to 3 parts of graphite powder and 1 to 3 parts of organic resin. The preparation method comprises the following steps of: mixing the forsterite sand, the graphite powder and the organic resin in a proportion, preblending, dry-mixing, adding tap water for wet mixed milling, drying and sieving to obtain the dry forsterite sand for the full-mould casting. The dry forsterite sand for the full-mould casting can overcome the defects that the flowability and the filling property of artificial forsterite sand are insufficient, the forsterite sand is slightly alkaline and is only applicable to the production of alkaline high-alloy steel castings, and the application range is too narrow, and promotes the development of full-mold casting industry.

Description

technical field [0001] The invention relates to a filling dry sand for full mold casting, in particular to a new filling dry sand special for full mold casting which is coated and denatured on forsterite sand. Background technique [0002] Generally, forsterite sand is artificial sand, which is triangular or polygonal, with poor flow filling performance, and forsterite sand is alkaline, and its application area is narrow. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a full mold casting forsterite dry sand and its preparation method, which can improve the artificial forsterite sand’s insufficient flow filling and forsterite’s partial alkalinity, and is only suitable for alkaline high-alloy In the production of steel castings, the application surface is too narrow. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a kind of full mold c...
