Abstract
The invention discloses a kind of environment-friendlymolding molding sand, relate to casting Material Field, the weight portion of its constitutive material is: silica sand 60～70 parts, chromite sand 5～10 parts, domestic garbage cinder 30～40 parts, flyash 6～8 parts, pulverized limestone 6～8 parts, furane resins 3～5 parts, coal dust 4～10 parts.The domestic garbage cinder and the flyash that add in the molding sand of the present invention are all the recyclings to refuse, and, low cost of the present invention, chill effect, refractoriness and good permeability, anti-burning into sand performance is high, and scab is few, for small-sized steel casting, can significantly improve its yield rate.
Description
Technical field
The present invention relates to casting Material Field, refer more particularly to a kind of environment-friendlymolding molding sand.
Background technology
Molding sand is the material in casting for moulding.Molding sand is typically by Foundry sand, moulding sand binder and additional thing
Mixing according to a certain percentage Deng Modeling Material, molding sand effect in Foundry Production is particularly important, because of the matter of molding sand
Measure casting wasted product that is bad and that cause and account for the 30～50% of the total waste product of foundry goods.The generally requirement to molding sand is: first,
There is higher intensity and heat stability, to bear the effect of various external force and high temperature；Second, good mobility,
The ability that i.e. molding sand is mutually shifted between sand grains under external force or action of gravity own；3rd, certain plasticity, i.e. type
Sand deforms under external force, can keep the ability of the shape given after external force is removed；4th, the most ventilative
Property, i.e. molding sand hole is through the ability of gas；5th, high collapsibility, also known as knockability, i.e. after casting solidification
Whether molding sand is easily destroyed, if the performance easily removed from foundry goods.
The allowance of small-sized steel casting only has 3～5mm, and requires that casting section thickness error is little, and surface is without sand holes, folder
Sand is few, the internal defect such as pore-free and shrinkage cavity.But, molding sand of the prior art, existence more or less these ask
Topic, main, along with the growth of the molding sand prices of raw materials, the cost of molding sand casting is increasingly higher.
Summary of the invention
The present invention provides a kind of environment-friendlymolding molding sand, solves in prior art, and common sand can not meet the casting of little shaped steel
Part wall thickness deflection is little, scab to be lacked, and dimple is few, internal porosity and the few requirement of shrinkage cavity, and molding sand price
High problem.
For solving above-mentioned technical problem, the technical scheme that the present invention provides is:
A kind of environment-friendlymolding molding sand of the present invention, the weight portion of its constitutive material is: silica sand 60～70 parts, chromite
Sand 5～10 parts, domestic garbage cinder 30～40 parts, flyash 6～8 parts, pulverized limestone 6～8 parts, furane resins 3～5
Part, coal dust 4～10 parts.
Further, described domestic garbage cinder is the bottom ash after common burning city domestic garbage.
Further, the characteristic of char residue of described coal dust is 4～5 grades.
Further, described domestic garbage cinder particle diameter is between 200 mesh～20 mesh.
Further, described flyash particle diameter is between 200 mesh～50 mesh.
Further, in described domestic garbage cinder, each substances in percentage by weight is: SiO245%～60%,
Fe2O310%～15%, Al2O310%～18%, CaO 10%～16%, TiO20.8%～1.2%, MgO 1%～3%,
K2O 0～2.5%, Na2O 0～2.5%, P2O52.5%～3.5%.
The technical scheme using the present invention to provide, compared with existing known technology, has the advantages that
(1) a kind of environment-friendlymolding molding sand of the present invention, the domestic garbage cinder, the flyash that add in molding sand are all right
The recycling of refuse, economizes on resources, and reduces casting cost.
(2) a kind of environment-friendlymolding molding sand of the present invention, chill effect, refractoriness and good permeability, anti-burning into sand performance
Height, scab is few, and for small-sized steel casting, yield rate is high.
(3) a kind of environment-friendlymolding molding sand of the present invention, manufacture method is simple, and formula is reasonable.
