Embodiment 1
[0029] A metallurgical casting mold, the materials of which are calculated by weight: 40 kg of silica sand, 30 kg of zircon sand, 10 kg of refractory glue, 5 kg of graphite, 4 kg of auxiliary materials, and 6 kg of molding sand binder. Among them, the auxiliary material is coal powder or sawdust, and the molding sand binder is one or more of clay, water glass, cement, phosphate, carboxymethyl cellulose and asphalt.
Embodiment 2
[0031] A metallurgical casting mold, the materials of which are calculated by weight: 50 kg of silica sand, 35 kg of zircon sand, 15 kg of refractory glue, 9 kg of graphite, 10 kg of auxiliary materials, and 18 kg of molding sand binder. Among them, the auxiliary material is coal powder or sawdust, and the molding sand binder is one or more of clay, water glass, cement, phosphate, carboxymethyl cellulose and asphalt.
Embodiment 3
[0033] A metallurgical casting mold, the materials of which are calculated by weight: 42 kg of silica sand, 31 kg of zircon sand, 12 kg of refractory glue, 6 kg of graphite, 5 kg of auxiliary materials, and 8 kg of molding sand binder. Among them, the auxiliary material is coal powder or sawdust, and the molding sand binder is one or more of clay, water glass, cement, phosphate, carboxymethyl cellulose and asphalt.

Abstract
The invention discloses a metallurgical casting mould. The metallurgical casting mould comprises the following materials in part by weight: 40-50 parts of silica sand, 30-35 parts of zircon sand, 10-15 parts of refractory clay, 5-9 parts of graphite, 4-10 parts of auxiliary materials, and 6-18 parts of a molding sand binder. The metallurgical casting mould disclosed by the invention has the beneficial effects that because of the adding of refractory clay, graphite and other auxiliary materials, the hardness of the metallurgical casting mould is greatly increased, the metallurgical casting mould can satisfy the one-time mould-forming casting of large devices, is uneasy to collapse, and can adapt to the production needs of various devices.
Description
technical field [0001] The invention relates to metallurgical equipment, in particular to a metallurgical casting mold. Background technique [0002] A metallurgical mold is a container for making liquid metal into a solid casting in casting production. The interior of the container is called the cavity, and its outline is equivalent to the shape of the casting. The mold must withstand the high temperature and erosion of liquid metal, so it must have corresponding refractoriness and sufficient strength; after the metal is solidified and formed, it should be easier to separate from the casting. In order to meet these requirements, the existing sand casting generally uses foundry sand such as high refractoriness silica sand and zircon sand to mix with molding sand binder and other auxiliary materials to make molding sand as the material of the mold. However, the defects of the existing casting molds are also obvious, that is, the hardness is not enough, and it is easy to col...
