Abstract
The invention discloses foundry molding sand containing blast furnace slag. The foundry molding sand is prepared from the raw materials in parts by weight: 40-55 parts of mudstone particle, 3-5 parts of waste aluminum powder, 7-9 parts of graphite powder, 6-8 parts of bentonite, 2-5 parts of plant ash, 4-6 parts of granular blast furnace slag and 8-12 parts of water. The foundry molding sand is prepared by the steps: 1) weighing the plant ash, the granular blast furnace slag and the bentonite according to the proportion, and adding water accounting for the total quantity of 35-40 percent. With the adoption of the foundry molding sand, as coal powder is not added, and straw powder and the plant ash are mainly used as antisticking additives, the cost is lowered, and the surface smoothness of a casting is also improved.
Description
Technical field
The present invention relates to casting field, particularly sand casting field.
Background technology
At present, with the foundry goods that sand casting is produced, account for 80% of total foundry goods.The Modeling Material of sand casting occupies an important position in Foundry Production, and it directly affects energy resource consumption, the environmental pollution of Foundry Production, and the quality of foundry goods, production efficiency and cost.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.
Therefore coal dust clay green-sand has been not suitable with the needs of foundary industry scientific development and the Environment Protection Policy that current consumption reduction reduces discharging.So in recent years, in order to reduce the pollution of coal dust clay-bonded sand to environment, founder author managed to find suitable substitute always.
Summary of the invention
For the deficiencies in the prior art, one of object of the present invention is to provide a kind of casting sand that contains blast-furnace cinder, and this molding sand does not add coal dust, mainly take stalk powder, plant ash is antiseized auxiliary agent, to reducing costs, and improves surface finish of casting.
For achieving the above object, the technical solution used in the present invention is:
A casting sand that contains blast-furnace cinder, is comprised of the following component in weight portion: mud stone particle 40-55 part, aluminium scrap powder 3-5 part, graphite powder 7-9 part, bentonite 6-8 part, plant ash 2-5 part, granulated blast furnace slag 4-6 part, water 8-12 part, specifically preparation method is, 1) by proportioning, weigh plant ash, granulated blast furnace slag, bentonite, and add the water of total amount 35-40%, soak 5-7 hour and maintain the temperature at 120-150 ℃, obtaining slurry; 2) by proportioning, weigh mud stone particle, aluminium scrap powder, graphite powder, put into together puddle mixer and be dry mixed, mix 1.5-2 hour; 3) in puddle mixer, add again step 1) slurry and remaining water, mix after 2-4 hour, shake out.
Described granulated blast furnace slag granularity is 80-100 order.
The beneficial effect of the casting sand that contains blast-furnace cinder of the present invention is:
(1) molding sand of the present invention is not containing coal dust;
(2) adopting blast-furnace cinder and plant ash is antiseized auxiliary agent, and cost is low, economizes on resources;
(3), in casting process, do not produce pernicious gas poisonous, that have pollution, environmental protection;
(4) by the rational proportioning of each composition, make the molding sand quality of preparation excellent, the surface finish of casting that adopts this molding sand to produce is high.
The specific embodiment
A casting sand that contains blast-furnace cinder, is comprised of the following component in weight portion: mud stone particle 40-55 part, aluminium scrap powder 3-5 part, graphite powder 7-9 part, bentonite 6-8 part, plant ash 2-5 part, granulated blast furnace slag 4-6 part, water 8-12 part, specifically preparation method is, 1) by proportioning, weigh plant ash, granulated blast furnace slag, bentonite, and add the water of total amount 35-40%, soak 5-7 hour and maintain the temperature at 120-150 ℃, obtaining slurry; 2) by proportioning, weigh mud stone particle, aluminium scrap powder, graphite powder, put into together puddle mixer and be dry mixed, mix 1.5-2 hour; 3) in puddle mixer, add again step 1) slurry and remaining water, mix after 2-4 hour, shake out, granulated blast furnace slag granularity is 80-100 order.
The processing performance of the casting sand that contains blast-furnace cinder by the present invention is:
Green compression strength (MPa) 0.084-0.095
Gas permeability 97
Hot green tensile strength (KPa) 310-320
Shatter index (j :) 80-83%.
Claims (2)
1. a casting sand that contains blast-furnace cinder, is characterized in that, the following component in weight portion, consists of: mud stone particle 40-55 part, aluminium scrap powder 3-5 part, graphite powder 7-9 part, bentonite 6-8 part, plant ash 2-5 part, granulated blast furnace slag 4-6 part, water 8-12 part, concrete preparation method is, 1) by proportioning, weigh plant ash, granulated blast furnace slag, bentonite, the water that adds total amount 35-40%, soaks 5-7 hour and maintains the temperature at 120-150 ℃, obtains slurry; 2) by proportioning, weigh mud stone particle, aluminium scrap powder, graphite powder, put into together puddle mixer and be dry mixed, mix 1.5-2 hour; 3) in puddle mixer, add again step 1) slurry and remaining water, mix after 2-4 hour, shake out.
2. the casting sand that contains blast-furnace cinder claimed in claim 1, is characterized in that, described granulated blast furnace slag granularity is 80-100 order.
