Abstract
The invention discloses an aluminum alloy covering agent. The covering agent comprises following components in percentage by weight: 7-12% of Na2SO4, 6-12% of Na2SiF6, 45-53% of NaCl and 28%-35% of KCl. The aluminum alloy covering agent has the beneficial effects that the smelting temperature of the covering agent is moderate and the smelting speed is rapid; the expansion speed is rapid and an oil-shaped thin film is formed on the surface of a casting, so as to effectively prevent the casting from being oxidized and burnt and sucking air.
Description
Technical field
The present invention relates to a kind of aluminium alloy covering agent, belong to metal surface protection field.
Background technology
Aluminium is more active metal, and it easily forms the slag inclusion of oxide compound during melting 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, aluminium alloy needs to prevent the oxidization burning loss of metal melt and air-breathing with a large amount of flux in fusion process, and can degasification slagging-off.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of aluminium alloy covering agent.
To achieve these goals, technical scheme of the present invention is: a kind of aluminium alloy covering agent, the component formulation weight ratio of described insulating covering agent is: Na
2sO
47～12%, Na
2siF
66～12%, NaCl 45～53%, KCl 28～35%.
Further, as a kind of preferred embodiment, the component formulation weight ratio of described insulating covering agent is: Na
2sO
410%, Na
2siF
68%, NaCl 50%, KCl 32%.
According to above-mentioned component formulation weight, than proportioning raw materials is good, by agitator, mix, the flux mixing is put into roaster and dry, enter afterwards ball mill and pulverize.
The invention has the beneficial effects as follows: the temperature of fusion of insulating covering agent of the present invention is suitable, fast, propagation rate is fast in fusing, at cast(ing) surface, forms one deck oily film, effectively prevents foundry goods oxidization burning loss, air-breathing.
Embodiment
Below in conjunction with specific embodiment, the present invention is described further.
