Abstract
The anti-stick sand coating of a kind of zirconium matter whey base cast steel main adopts that the anti-current of being made up of attaclay, calcium bentonite is dropped down, viscosity reduction, sintering aid; Bonding, the suspending agent formed by complex emulsion, lithium bentonite, silica sol, sodium carboxymethylcellulose; Refractory powder of being made up of zirconium English powder, silica flour and the auxiliary material of being made up of sodium methylene bis-naphthalene sulfonate, titanium dioxide constitute.The viscosity of coating is suitable, and the mo(u)ld blacking layer thickness is more even, the coating 50mg/cm that weighs
2, anti-stick grittiness is good, easily peels off after the cast, and cost reduces by 1/2 more at least with full zirconium English powder, and suspendability is good, and coating property is constant in six months, is specially adapted to big (100～200mm) the steel-casting of wall thickness.
Description
The invention belongs to the anti-stick sand coating of cast steel.
In the prior art field, the steel-casting bigger to wall thickness, in order to prevent scab, alleviate the amount of labour of cleaning foundry goods, reduce the surface roughness of foundry goods, often need be with expensive full zircon flour coating, silica flour or aluminium vanadine coating as using, because their refractoriness are not high, easy-sintering not again is so anti-stick grittiness is poor; Under the simultaneously more difficult situation that reaches and difficult trickling little, once brush into the suitable and uniform coating of thickness at the brushing resistance.
The objective of the invention is to be developed into a kind of easy brushing, the anti-stick sand coating of the suitable and uniform zirconium matter of thickness whey base cast steel is dropped down, once brushes in anti-current, is specially adapted to the bigger carbon steel and low alloy steel foundry goods of wall thickness.
Coating of the present invention adopts mainly that (weight %) anti-current is dropped down, viscosity reduction, sintering aid 3～6%, and bonding, suspending agent 5～8%, refractory powder 86～90%, other auxiliary material 0.3～0.6% and outer amount of water are the water formation of above-mentioned total amount 45～55%.
Anti-current is dropped down, viscosity reduction, its composition of sintering aid are (weight %): contain the attaclay 1.0～5.0% of MgO12.5～17.1%, 0.5～2.0% composition of calcium bentonite.
Bonding, its composition of suspending agent are (weight %): lithium bentonite 0.5～2.0%, silica sol 1～2.5%, sodium carboxymethylcellulose 0.1～0.4%, 0.7～1.5% composition of complex emulsion.Its composition of complex emulsion is (weight %): polyoxyethylene Octyl Ether-10 0.07～0.18%, cis-18-ene--9-acid 0.02～0.05%, silica sol 0.15～0.4%, drying oil (as tung oil) 0.4～1.0% and suitable quantity of water (equilibrium valve) composition.
Its composition of refractory powder is (weight %): zirconium English powder 21～35%, 51～65% compositions of silica flour.At this compositing range, according to the mineral phasor, refractoriness can be higher.
Its composition of other auxiliary material is (weight %): sodium methylene bis-naphthalene sulfonate 0.05～0.15%, 0.2～0.5% composition of titanium dioxide.
Coating of the present invention owing to be added with and can anti-current drop down, can also reduce the attaclay of viscosity, and it makes the coating slip have excellent colloid and rheological behavior.It has improved full the dipping in property of brush pen and the sag resistance in the brushing process, and viscosity resistance is less simultaneously, once brushes into the even coating of the suitable plane of thickness, lateral thickness, and dope layer is heavy can to reach 50mg/cm
2Simultaneously because attaclay has the effect that helps sintering concurrently, the cortex that is coated with after the cast is easily peeled off from steel casting surface, obtain the lower casting surface of surface roughness.
Contain in bonding of the present invention, the suspending agent height, in, the normal temperature binding agent, making continues in the scope of coating from normal temperature to molten steel high temperature all good cohesive force, does not chap in dry and scorching hot process.The complex emulsion that adopts is highly stable, oil droplet decentralization height, and coating is difficult for moisture absorption and gets damp behind the mold drying; Coating generation explosion is peeled off with foundry goods produce pore.
Coating of the present invention, owing to contain the surfactant of making emulsifying agent, so loam mould (core) sand, resin sand, oil-sand and water-glass sand all are suitable for, applicability is strong, and has stability for storage, and coating property is constant in six months, this coating compares with full zirconium English powder, cost then reduces by 1/2 at least, and about 1700 yuan/ton of unit price is specially adapted to big (100～200mm) the carbon steel or low alloy steel foundry goods of wall thickness.
Be embodiments of the invention (weight %) below:
1. when in 0.4～1.0% drying oil, stirring, successively add cis-18-ene--9-acid 0.02～0.05% and polyoxyethylene Octyl Ether-10 0.07～0.18%, and then adding silica sol 0.15～0.4%, add suitable quantity of water at last, stirred 10～15 minutes, and can make complex emulsion.
2. add bonding, suspending agent 5～8% outside in the dosage water yield earlier, wherein: complex emulsion 0.7～1.5%, sodium carboxymethylcellulose 0.1～0.4% is that the mode of 2% carboxymethylcellulose sodium solution adds with concentration then, stirs in agitator 10～15 minutes.Add again as anti-current drop down, the attaclay 1～5% and the calcium bentonite 0.5～2.0% of viscosity reduction, sintering aid, continue to stir 10～15 minutes, subsequently, constantly add refractory powder 86～90% successively successively: silica flour 51～65% and zirconium English powder 21～35%, and other auxiliary material: sodium methylene bis-naphthalene sulfonate 0.05～0.15%, titanium dioxide 0.2～0.5% stirred 10～15 minutes again.
3. the above-mentioned compound that has stirred after grinding 3～5 minutes, colloid mill is promptly made coating of the present invention.
