Abstract
The invention belongs to the technical field of casting materials and particularly relates to novel foundry sand and a preparation method thereof. The preparation method comprises the following steps: taking crude sand, a binder and water as raw materials; adding crude sand into a sand mixer at first; starting up the sand mixer, then adding water into the sand mixer and stirring for uniform mixing; and after that, adding the binder, and stirring to prepare the novel foundry sand. The novel foundry sand has the advantages that the cost is low, the preparation method is simple, the use efficiency is high, reusability is realized, the novel foundry sand is very suitable for automatic core mold manufacturing equipment, a manufactured core mold is smooth in surface, high in hardness and very suitable for pipe fitting casting, and the pipe fitting casting cost is lowered.
Description
Technical field
The invention belongs to mold material technical field, and in particular to a kind of novel casting sand and preparation method thereof.
Background technology
Casting model powder belongs to one kind of casting industry mold material, the mold material that existing casting industry is used have precoated sand,
The casting model powder of resin sand and some autonomous proportionings, it is relatively costly that this casting model powder has a casting industry mold material, making side
Method is complicated, and service efficiency is low, and can only disposable shortcoming.
The content of the invention
The purpose of the present invention is the mold material high cost existed in the existing casting model powder for using for solution casting industry,
Service efficiency is low, and can only disposable problem, and provide a kind of novel casting sand and preparation method thereof.
For achieving the above object, the technical solution adopted in the present invention：
A kind of novel casting sand, is made up of the raw material of following percentage by weight：
Roughing sand 92%～94%, binding agent 2%～4%, water 2%～4%.
A kind of method for preparing the novel casting sand, comprises the following steps：
1) roughing sand for taking dry 92%～94% is added to puddle mixer；
2) puddle mixer is opened, then 2%～4% water is added toward puddle mixer, stirred 3～5 minutes so as to be sufficiently stirred for
It is even；
3) again toward stir the step of 2) in add 2%～4% binding agent, stir 10～15 minutes, be obtained it is new
Casting model powder.
Compared with prior art, the present invention has advantages below：First, casting model powder low cost, preparation method is simple, uses
Efficiency high, can reuse；Secondth, the novel casting sand that the present invention is fabricated to is used for a kind of automated production core equipment,
The mandrel surface of making is smooth, and hardness is high, is highly suitable for pipe fitting casting, has saved the cost of pipe fitting casting.
