Abstract
The invention relates to high efficiency distortion aluminum and aluminum alloy sediment removing agent and the making method and the application. It is made up from NaCl 25-45wt%, KCl 30-50wt%, CaCl23-7wt%, AlCl3 1-6wt%, and Na3AIF 1-6wt%. The invention is suited to the condition of Mg content below 2%, and using temperature at 700-800 degree centigrade.
Description
Technical field:
The minimizing of using when the present invention relates to the casting of a kind of aluminium and aluminium alloy smelting plays the slagging agent that touches with the air knot, the making method and the application thereof of slagging agent.
Background technology:
Aluminium is more active metal, it forms the slag inclusion of oxide compound during melting easily and absorbs gas under atmosphere, if these oxide compounds and gas enter ingot casting with melt, will form slag inclusion, oxide film, pore, loose or other defect, reduce physicals, the corrosion resistance of product, also can worsen the process industrial art performance of alloy, therefore, the oxidization burning loss that aluminium alloy needs to use a large amount of flux to prevent metal melt in fusion process and air-breathing, and can the degasification slagging-off.
Summary of the invention:
The purpose of this invention is to provide a kind of distortion aluminium and aluminium alloy slagging agent, reduce the molten aluminium scaling loss, the present invention also comprises the making method and the application of this slagging agent.
Above-mentioned purpose realizes by following technical scheme:
Distortion aluminium and aluminium alloy slagging agent, described slagging agent is grouped into by following one-tenth: sodium-chlor 20-40, Repone K 25-45, sodium sulfate 1-5, yellow soda ash 1-5, zinc chloride 1-3, calcium chloride 2-5, Sodium Silicofluoride 2-10, Na
3AIF
61-6, above proportioning is a ratio of weight and number.
Above-mentioned distortion aluminium and aluminium alloy slagging agent also comprise hexachloroethane 2-5 in the described slagging agent, above proportioning is a ratio of weight and number.
Above-mentioned slagging agent is in distortion aluminium and aluminium alloy smelting Application in Casting.
The making method of distortion aluminium and aluminium alloy slagging agent, after according to above-mentioned ratio of weight and number raw material being prepared, mix by agitator, the flux that mixes is put into roaster, dried 3-4 hour down at 300 ℃, pulverize again after the oven dry, after the pulverizing, sieve, then it is packed with the waterproof plastic bag.
This technical scheme has following beneficial effect:
1. generally contain 80% aluminium and 20% aluminum oxide in the scum silica frost,, wherein most aluminium is discharged, make slag become loose and dry if adopt the suitable slagging agent of tension force.Product of the present invention has rational surface tension and viscosity, can adsorb, dissolve the oxide residue in the melt, can be easy to again separate, effectively the aluminium in the slag be separated with alloy melt, aluminium content in the scum silica frost is reduced greatly, almost the degree that does not have on the macroscopic view.
2. the material that contains solar heat protection material (as yellow soda ash, Sodium Silicofluoride) and dissolved oxygen aluminium among the present invention, these materials are emitted a large amount of heat when reaction, help when reaction, to increase wettability and penetrate the slag surface film oxide, from slag, isolate aluminium, when preventing hot substance reaction, generate silicon oxide and sodium oxide, increased the surface tension and the viscosity of flux so again, made the separating effect of slag and aluminium liquid become better.Through repeatedly check, present slag has become the dried slag of loose canescence.
Through the check, the add-on of this product directly influences the quality of product, flux very little, then thermal discharge is few, the flux effect is bad, and flux is too many, and thermal discharge is many, produces a large amount of smog, can aggravate the scaling loss of aluminium, the add-on that the present invention adopts is aluminium liquid quality 0.2-1%, has reached best effect.
The specific embodiment of the present invention:
Embodiment 1:
Distortion aluminium and aluminium alloy slagging agent, described slagging agent is grouped into by following one-tenth: sodium-chlor 20, Repone K 25, sodium sulfate 1, yellow soda ash 1, zinc chloride 1, calcium chloride 2, Sodium Silicofluoride 2, Na
3AIF
61,
Above proportioning is a ratio of weight and number.
Embodiment 2:
Distortion aluminium and aluminium alloy slagging agent, described slagging agent is grouped into by following one-tenth: sodium-chlor 40, Repone K 45, sodium sulfate 5, yellow soda ash 5, zinc chloride 3, calcium chloride 5, Sodium Silicofluoride 10, Na
3AIF
66, hexachloroethane 2 above proportionings are ratio of weight and number.
Embodiment 3:
Distortion aluminium and aluminium alloy slagging agent, it is characterized in that: described slagging agent is grouped into by following one-tenth: sodium-chlor 30, Repone K 35, sodium sulfate 3, yellow soda ash 3, zinc chloride 2, calcium chloride 4, Sodium Silicofluoride 5, Na
3AIF
64, hexachloroethane 5, above proportioning is a ratio of weight and number.
Embodiment 4:
The making method of above slagging agent, select component according to weight proportion and kind, because halogenide comprises muriatic salt and absorbs water easily or contain crystal water, and the formation bulk, need to pulverize filtration and carry out proportioning according to its content of effective, after according to ratio of weight and number raw material being prepared, mix by agitator, the flux that mixes is put into roaster, dried 3-4 hour down at 300 ℃, the material after the oven dry often forms bulk again, need pulverize again, after the pulverizing, sieve, then plastic bag packaging is prevented suction.
In the fusion process of aluminium and aluminium alloy, under 700-800 ℃ of situation, this product is disperseed to be sprinkled in the molten aluminium uniformly, after stirring, it produces loose linen scum silica frost, and it is clawed the back check, and it is few wherein to contain aluminium.Effectively prevented the oxidization burning loss of metal melt and air-breathing thus, and can the degasification slagging-off.
This product is applicable to magnesium content less than 2%, under the use temperature 700-800 ℃ of situation, and the slagging agent of aluminium content in the minimizing slag that aluminium and aluminium alloy use when smelting founding.
Claims (4)
1. one kind is out of shape aluminium and aluminium alloy slagging agent, and it is characterized in that: described slagging agent is grouped into by following one-tenth: sodium-chlor 20-40, Repone K 25-45, sodium sulfate 1-5, yellow soda ash 1-5, zinc chloride 1-3, calcium chloride 2-5, Sodium Silicofluoride 2-10, Na
