Description
Technical field
The present invention relates to machinery manufacturing technology field, more particularly to a kind of swage type for the coefficient of expansion for reducing quartz sand
Sand.
Background technology
Molding sand is used for the material of moulding in casting.Molding sand is typically by Foundry sand, moulding sand binder and additional thing etc.
Modeling Material mixes according to a certain percentage.Molding sand presses binding agent difference used, can be divided into clay-bonded sand, water-glass sand, cement
Sand, resin sand etc..With the most of clay-bonded sand, water-glass sand and resin sand.
Effect of the molding sand in Foundry Production is particularly important, because of the poor quality of molding sand and caused by casting wasted product account for casting
The 30 ~ 50% of the total waste product of part.Requirement generally to molding sand is:1. there is higher intensity and heat endurance, to bear various external force
With the effect of high temperature.2. the ability that good mobility, i.e. molding sand are mutually shifted under external force or Action of Gravity Field itself between sand grains.
3. certain plasticity, i.e. molding sand deform under external force, the ability of given shape can be kept after external force removes.④
Preferable gas permeability, i.e. molding sand hole pass through the ability of gas.5. high collapsibility, also known as knockability, i.e., after casting solidification
Whether molding sand is easily destroyed, if the performance easily removed from casting.
The invention provides a kind of swage molding sand for the coefficient of expansion for reducing quartz sand.
