Abstract
The invention discloses high-efficiency chilling casting sand which is prepared from the following raw materials: 270-290 parts by weight of chromite sand, 40-50 parts by weight of alumina, 20-30 parts by weight of brown aluminum oxide, 20-30 parts by weight of mushroom residue, 1-2 parts by weight of aluminum powder, 3-4 parts by weight of carboxymethylcellulose, 30-40 parts by weight of ammonium alum, 2-3 parts by weight of sodium tripolyphosphate, 20-25 parts by weight of bran, 2-3 parts by weight of dodecylbenzene sulfonic acid, 2-3 parts by weight of pine tar, 1-2 parts by weight of colza oil, 12-15 parts by weight of furan resin, 12-15 parts by weight of benzenesulfonic acid, 40-45 parts by weight of wood charcoal and a proper amount of water. The mushroom residue, the bran and the like are used and calcined, thus the air permeability of casting sand is increased, energy resources are saved, and environment is protected; by using the chromite sand, the alumina and the brown aluminum oxide, the expansion factor is low, the casting size is accurate, the plasticity is good, and the high temperature is resisted; by combining with the pine tar, the colza oil and the furan resin, the high-temperature collapsibility is good; by using the aluminum powder, the heat conduction performance is improved, and the effect of a chilling casting is enhanced.
Description
Technical field
The present invention relates to casting field, relate in particular to a kind of efficient Quench molding sand and preparation method thereof.
Background technology
Molding sand is in casting, to be used for the material of moulding.Molding sand is generally mixed according to a certain percentage by Modeling Materials such as Foundry sand, moulding sand binder and additional things, also available natural silica sand argillaceous, the sand formulation Sand particle diameter that common cast aluminium is used is too large or too little, molding sand material footpath is too large, although gas permeability is better, aloxite part surface ratio is more coarse, fineness is bad, molding sand material footpath is too little, causes sand mold gas permeability bad, and aluminium casting has pore to produce.Domestic and international widely used coal dust clay green-sand, generally by the mixed system of roughing sand, binding agent, coal dust additive etc. and water, formed, there is certain anti-scab effect and the cost of material is low, production efficiency is high, but its consumption is large, discharge is serious, at casting process coal dust firing, decompose and produce toxic gas and pollute.
Molding sand is different by binding agent used, can be divided into clay-bonded sand, water-glass sand, cement bonded sand, quartz sand etc., and that with clay-bonded sand, water-glass sand and quartz sand, uses is maximum.The effect of molding sand in Foundry Production is very important, and the casting wasted product causing because of the poor quality of molding sand accounts for 30～50% of the total waste product of foundry goods.Conventionally to the requirement of molding sand, be: 1, there is higher intensity and heat endurance, to bear the effect of various external force and high temperature.2, good mobility, the ability that molding sand mutually moves between sand grains under external force or Action of Gravity Field own.3, certain plasticity, molding sand is out of shape under external force, can keep the ability of the shape that gives after external force is removed.4, good gas permeability, molding sand hole sees through the ability of gas.5, high collapsibility, weighs up again grittiness, and after casting solidification, whether molding sand easily destroys, the performance of whether easily removing from foundry goods.
Current casting field development rapidly, higher for the performance requirement of steel-casting and ironcasting, thereby require further to promote the performance of molding sand.
Summary of the invention
The object of the present invention is to provide a kind of efficient Quench molding sand and preparation method thereof, this molding sand has that high thermal conductivity, plasticity are good, good permeability, feature that collapsibility is good.
Technical scheme of the present invention is as follows:
An efficient Quench molding sand, is characterized in that being made by the raw material of following weight portion: chromite sand 270-290, alumina 40-50, brown corundum 20-30, mushroom bacterium chaff 20-30, aluminium powder 1-2, carboxymethyl cellulose 3-4, ammonia-alum 30-40, sodium phosphate trimer 2-3, wheat bran 20-25, DBSA 2-3, pine tar 2-3, rapeseed oil 1-2, furane resins 12-15, benzene sulfonic acid 12-15, charcoal 40-45, water are appropriate.
The preparation method of described efficient Quench molding sand, it is characterized in that comprising the following steps: chromite sand, alumina, brown corundum, mushroom bacterium chaff are put into 550-570 ℃ of calcining furnace and calcine 3-4 hour, then, take out, be ground into 200-300 order powder, then add wheat bran, ammonia-alum, DBSA, suitable quantity of water, dispersed with stirring, pugging, sends in 1410-1440 ℃ of calcining furnace and calcines 3-5 hour, taking-up is crushed to 50-100 order, obtains calcining material; Carboxymethyl cellulose, sodium phosphate trimer, furane resins, benzene sulfonic acid, charcoal are mixed, grind 30-40 minute, mix 15-20 minute with calcining material, other residual components, obtain.
Beneficial effect of the present invention
The present invention has used mushroom bacterium chaff, wheat bran etc., through calcining, has increased type sand permeability, has saved the energy, has protected environment; By using chromite sand, alumina, brown corundum to make molding sand, the coefficient of expansion is low, casting dimension is accurate, plasticity is good, high temperature resistant; Be combined with pine tar, rapeseed oil, furane resins, make high temperature collapsibility good; By using aluminium powder to increase heat conductivility, strengthened Quench foundry goods effect.
