Abstract

The invention discloses molding sand for casting a vermicular iron flywheel and a preparation method thereof, and relates to the technical field of molding sand. The molding sand comprises the following components in parts by weight: 60-90 parts of new sand, 8-12 parts of water, 6-8 parts of mixed powder, 8-10 parts of bentonite, 2-5 parts of pulverized coal, 1-2 parts of ash and 8-15 parts of used sand. By adding the used sand, on one hand, the manufacturing cost of the molding sand can be reduced, on the other hand, the repeated utilization rate of the molding sand is improved, the waste of resources is reduced, and by adding pulverized coal, the situation that sand is burnt on a casting can be reduced, and the roughness of the surface of the casting is reduced.

Description

technical field [0001] The invention belongs to the technical field of molding sand, and in particular relates to molding sand for casting vermicular iron flywheels and a preparation method thereof. Background technique [0002] Molding sand is a material used for molding in sand casting. The performance of molding sand plays an extremely important role in casting production, usually including high strength and thermal stability, good fluidity, certain plasticity, good air permeability and high collapse. For the molding sand of different uses, there are large or small differences in the performance of the molding sand. [0003] In the prior art, when casting vermicular iron flywheel castings, sand will be included on the surface of the finished casting, the surface roughness of the finished product is poor, and the cost in the casting process is high. Contents of the invention [0004] The object of the present invention is to provide a kind of mold sand for casting vermi...
