Abstract
The present invention relates to lubricant for moulding. The components of the lubricant comprise by weight portion: 20% to 60% of graphite powder, 10% to 30% of thickening agents, 10% to 40% of cellulose ether and 5% to 10% of sodium tripolyphosphate, wherein a liquid material which is formed after graphite, the thickening agents, the cellulose ether and the sodium tripolyphosphate are combined can be sprayed or coated at the inner wall of a slag tank; high temperature molten metal can not damage the lubricant. Thus, the lubricant has a certain lubrication and protection function on the slag tank, and the lubricant can slowly burn under the function of air or oxygen. The present invention can not influence the quality of smelting metal.
Description
Technical field:
The present invention relates to a kind of lubricant for moulding of used slag ladle inner surface when being used to be coated in metal smelting.
Background technology:
When the platform gold metallurgy belongs to, need usually with slag ladle splendid attire molten metal, owing to have the inwall that the molten metal of higher temperature very easily corrodes slag ladle, and liquid metal also is difficult for the demoulding.For this reason; in the prior art; directly contact, prevent sintering with slag ladle for fear of molten metal; usually before the splendid attire molten metal, earlier lubricant or releasing agent are coated in the inner surface of slag ladle; and formation one deck coating; so that protection against oxidation is carried out on its surface, also be beneficial to simultaneously and remove impurity in the metal.
" mould fluxes that is used for continuous casting steel machine " of No. 1152266 bulletins of Chinese patent is to be protection a kind of scheme that crystallizer proposed.The flux that this patent proposed is to be major ingredient with the refractory metal oxide, is flux with carbon black, manganese dioxide and starch, and adding has multiple auxiliary agent and blowing agent.Its meaning is to want to utilize the particle that joins in the crystallizer, so that flux provides lubricated between crystallizer inwall and steel, promptly can reduce heat and scatter and disappear from the steel surface, can also prevent the impurity in steel surface oxidation and the removal steel simultaneously.But the fusing point of this flux must be higher than the fusing point of molten metal, otherwise molten metal can be with its fusing in the process of crystallizer intercrystalline, and then the effect that does not reach protection crystallizer inwall; Because granular flux is suspended in molten state molten steel surface easily or merges in the molten state molten steel; and can not overlay on well within the predetermined time on the crystallizer inwall; so, this flux to the protection crystallizer inwall and the smooth demoulding of molten steel aspect is also had in certain problem.
In addition, " the continuous cast mold high-temperature lubricant and the manufacture craft thereof " of No. 1159123 bulletins of Chinese patent is a kind of lubricants.The lubricant that this patent proposed is that how phenol, acrylic acid and water are formulated by crystalline flake graphite, carbon black, bentonite, Ludox, sodium phosphate trimer, carboxymethyl cellulose, second.Though this kind lubricant can play certain lubricated and protective effect to crystallizer, but, this lubricant has adopted the bigger materials of silicon content such as carbon black, Ludox, and the fusing point of silicon is 1750 ℃, so, these silicon that contain in the silicon materials are easy to be penetrated in metal such as the molten steel, and then change metal components; Simultaneously how organic costs such as phenol and acrylic acid are relative higher for second, and lubricant adds the raising that these compositions can directly cause cost of manufacture.
Up to the present, also there be not very desirable being used to of discovery to protect the coating of slag ladle inwall or the relevant information of lubricant.
Summary of the invention:
The mode that task of the present invention provides a kind of utilization smoulder at high temperature solves slag ladle and is etched lubricant for moulding with the cost of manufacture problem.
Lubricant for moulding proposed by the invention, the weight quota of its each component is respectively: graphite powder 20%-60%, thickener 10%-30%, cellulose ether 10%-40%, sodium phosphate trimer 5%-10%.Wherein, graphite is a kind of variant of crystalline state simple substance carbon, also is a kind of resistant to elevated temperatures stabilizing agent, and heat-flash meeting smoulder in air or oxygen; Cellulose ether has good wetting, dispersive property.Graphite combines with thickener, cellulose ether and sodium phosphate trimer and is subjected to understand smoulder behind the heat-flash under the effect of oxygen.
Described thickener is made of bentonite or organobentonite or diatomite, and described cellulose ether is selected methylcellulose or carboxymethyl cellulose for use.Bentonite has certain suction clothes ability to organic matter, and has certain viscosity and lubricity; And the equal viscosity of methylcellulose and carboxymethyl cellulose has the characteristic that the rising with temperature descends, and when its temperature rose to a certain degree, its viscosity forever reduced.
The weight quota of described lubricant each component is respectively: graphite powder 30%-40%, bentonite or organobentonite or diatomite 20%-30%, methylcellulose or carboxymethyl cellulose 20%-40%, sodium phosphate trimer 5%-10%.
In the present invention, graphite and thickener, cellulose ether and sodium phosphate trimer can spray or be coated in the inwall of slag ladle in conjunction with the formed liquid material in back, after molten metal or molten steel are poured in it, because this lubricant has the effect that isolating metal liquid and the inwall of slag ladle directly contact, and this resistant to elevated temperatures stabilizing agent of graphite is arranged in lubricant, even if the molten metal of high temperature can not destroy this lubricant yet, so, this lubricant can play certain lubricated and protective effect to slag ladle, and in the process that molten metal is poured out from slag ladle, this lubricant is the meeting smoulder under the effect of air or oxygen, composition in it can not be blended in the molten metal basically, so this lubricant can not have any impact to the quality of institute's smelting metal; In addition, what this lubricant adopted all is low-cost materials, and the relative prior art of its cost of manufacture is relatively low, but can realize very desirable technique effect.
